Talk:2025 Pacific hurricane season/ACE calcs

Modokai: /* Totals */

This is the page for calculating the [[Accumulated cyclone energy]] for the [[2025 Pacific hurricane season]]. If any storms of a season happen to cross years, the storm's ACE counts for the previous year.<ref>{{cite report|author=Stacy R. Stewart|title=Tropical Storm Zeta Discussion Number 30|url=http://www.nhc.noaa.gov/archive/2005/dis/al302005.discus.030.shtml?|publisher=National Hurricane Center|date=January 6, 2006|accessdate=May 17, 2020}}</ref> The ACE is calculated by [[Summation|summing]] the squares of the estimated maximum sustained velocity of every active tropical storm (wind speed 35 [[Knot (speed)|knots]] or higher), at six-hour intervals. The numbers are divided by 10,000 to make them more manageable. The unit of ACE is 104 kt2, and for use as an index the unit is assumed. Thus,

:<math>\text{ACE} = \sum_{}^{} \frac{{v_\mathrm{max}}^2}{10^4},</math>

where ''v''max is estimated sustained wind speed in knots.

== Article review ==

As the reviewer who marked this article as reviewed, also open to restoring redirect / draftying as it's a bit early. However, I think there's little harm in leaving the article as is as well. ~ '''[[User:BlueTurtles|BlueTurtles]]''' '''|''' [[User_Talk:BlueTurtles|talk]] 11:01, 12 January 2025 (UTC)
:I do think the article was premature. Typically, we wait for the first official forecast before creating the season article, as that is usually the first bit of information that will remain in the finished version of the article. ♫ [[User:Hurricanehink|Hurricanehink]] ([[User_talk:Hurricanehink|talk]]) 20:28, 12 January 2025 (UTC)

== First 2025 season forecast ==

TSR has released a forecast for 2025: https://www.tropicalstormrisk.com/docs/TSRATLForecastDecember2025.pdf. [[User:AwesomeAndEpicGamer|AwesomeAndEpicGamer]] ([[User talk:AwesomeAndEpicGamer|talk]]) 14:03, 11 December 2024 (UTC)

== Euro model forecast ==

The European Model has apparently issued a forecast for the season [https://www.khou.com/article/weather/hurricane/2025-hurricane-season-forecast/285-86aab8df-4f5b-4cd3-99fd-2583e4bc2426]. However, I feel like there are some red flags as the forecast seems odd compared to others. Can someone just give it a look over and their opinion on it?

The '''2025 Pacific hurricane season''' is the current [[Pacific hurricane season]] for the [[Northern Hemisphere]]. The season officially began on May 15, 2025, and ends on November 30, 2025. For the Central Pacific ([[140th meridian west|140ºW]] to [[180th meridian|180º]]), the season began on June 1, 2025, and it too ends on November 30, 2025. Those dates, adopted by convention, describe the period in which most subtropical or [[tropical cyclogenesis]] occurs in the [[Pacific Ocean]]. The first system of the season, Tropical Storm Alvin, formed off the coast of Southern Mexico on May 28, and remained over the open waters of the Eastern Pacific.

In advance of each [[Pacific hurricane]] season, [[Tropical cyclone seasonal forecasting|forecasts of hurricane activity]] are issued by forecasters from the United States [[National Oceanic and Atmospheric Administration]] (NOAA)'s [[Climate Prediction Center]], and [[Mexico]]'s [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN). The forecasts include weekly and monthly changes in significant factors that help determine the amount of tropical storms, hurricanes, and major hurricanes within a particular season.<ref name="Background"/>

According to NOAA, the average Pacific hurricane season between 1991 and 2020 contained about 15 named storms, 8 hurricanes and 4 major hurricanes (Category 3 and higher), as well as an [[Accumulated Cyclone Energy|accumulated cyclone energy]] (ACE) index of 80–115 units. Broadly speaking, ACE is the measure of the power of a tropical or [[subtropical cyclone]] multiplied by the length of time it existed. ACE is only calculated for full advisories on specific tropical or subtropical cyclones reaching wind speeds of 39 mph (63 km/h) or higher. NOAA typically describes a season as above-average, average, or below-average depending on the cumulative ACE index, but the number of tropical storms, hurricanes or major hurricanes can also be considered.<ref name="Background"/>

On May 7, 2025, the [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN) issued its first outlook for the Pacific hurricane season, forecasting an above average season with 16–20 named storms, 8–11 hurricanes, and 4–6 major hurricanes.<ref name="SMN"/> On May 22, the [[National Oceanic and Atmospheric Administration]] (NOAA) released its outlook for the eastern Pacific, which calls for a near-average season with 12 to 18 named storms, 5 to 10 hurricanes, and 2 to 5 major hurricanes, citing a continued neutral phase, the unlikelihood of an [[El Niño]], and the possibility of [[La Niña]] in the summer.<ref name="NOAA"/> This increases vertical wind shear in the basin and slightly reduces sea surface temperatures, thus favoring mild to moderate tropical cyclone activity. Furthermore, many global computer models predicted a negative [[Pacific decadal oscillation]] (PDO), a phase of a multi-decadal cycle that favored the continuation of much warmer-than-average sea surface temperatures, which had been occurring since [[2021 Pacific hurricane season|2021]], unlike the 1991-2020 period, which generally featured below-normal activity.<ref name="Background"/>

For storms that form in the North Pacific from 140°W to the [[International Date Line]], the names come from a series of four rotating lists. Names are used one after the other without regard to year, and when the bottom of one list is reached, the next named storm receives the name at the top of the next list.<ref name="ENP CNP"/> Any named storms that form within the area in 2025 will be listed below. Named storms in the table above that cross into the area during the season are noted (*).

==Season effects==
This is a table of all of the storms that have formed in the 2025 Pacific hurricane season. It includes their duration, names, intensities, areas affected, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2025 USD.

The '''2024–25 Australian region cyclone season''' was the most active, and first above-average season in the Australian region since [[2005–06 Australian region cyclone season|2005–06]]. This season also had the highest amount of severe tropical cyclones since 2005-06, as well as being the first non-below average season since [[2018–19 Australian region cyclone season|2018–19]]. The season recorded an average amount of tropical cyclones, an above average amount of tropical lows. It was also the third consecutive season with at least five severe tropical cyclones. The season officially started on 1 November 2024 and ended on 30 April 2025, however, a tropical cyclone could form at any time between 1 July 2024 and 30 June 2025 and would count towards the season total. During the season, tropical cyclones are officially monitored by one of the three tropical cyclone warning centres (TCWCs) for the region which are operated by the [[Australian Bureau of Meteorology]], National Weather Service of [[Papua New Guinea]] and the [[Indonesian Agency for Meteorology, Climatology and Geophysics]]. The United States [[Joint Typhoon Warning Center]] (JTWC) and other national meteorological services including [[Météo-France]] and the [[Fiji Meteorological Service]] will also monitor the basin during the season.

===Early season activity===
The season officially started on 1 November, 2024. On 14 November, the [[Bureau of Meteorology]] (BoM) noted that a tropical low may form west of Sumatra.<ref name="Sumatra TL"/> A westerly wind shear enhanced the disturbance's development. Despite moderate to high wind shear displacing deep convection, the tropical low further developed and the Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert. <ref name="TCFA 04U"/> On 28 November, the BoM named Tropical Cyclone ''Robyn''. The storm officially peaked as a high-end tropical storm before increasing wind shear caused the storm to dissipate. On 4 December, Tropical Low 04U formed off the coast of [[Java]] and headed west before dissipating on 11 December. Unfortunately, the disturbance caused landslides and floods, killing eleven people and leaving seven missing.<ref name="TL 04U Deaths"/><ref name="04U Deaths"/> The rest of December had Tropical Lows 02U, 06U, 07U, and 08U. Tropical Low 07U formed southeast of the [[Cocos (Keeling) Islands|Cocos Islands]] and JTWC designated it as a tropical storm. 08U later became Category 3 [[Cyclone Dikeledi]] in the Southwest Indian Ocean.

===Peak season activity===
The first half of January had Tropical Lows 09U and 10U. The latter half had Sean, 13U, Taliah, and Vince. On 17 January, the BoM designated Tropical Low 11U, which absorbed 10U, and later named ''Sean'' on 19 January. A day later, the storm rapidly intensified to a Category 4 major cyclone on the Australian cyclone scale, possessing a distinct eye and intense winds.<ref name="C4 Sean"/> Sean dissipated a couple days later. The cyclone caused heavy rainfall and gale-force winds across portions of Western Australia. A record amount of rain fell in [[Karratha, Western Australia|Karratha]], with 274.4 mm recorded within 24 hours on 20 January.<ref name="Sean rainfall"/> Tropical Low 13U briefly tracked along the coast of Queensland and flooding killed a 63 year old woman.<ref name="13U Fatality"/> On 31 January, the BoM designated Tropical Lows 14U and 15U, which were later named ''Taliah'' and ''Vince''. After dealing with moderate wind shear, on 3 February, Taliah peaked as a Category 3 severe tropical cyclone on the Australian cyclone scale and Category 2 on the SSHWS scale.<ref name="Cyclone Taliah"/> Taliah exited the basin on 12 February. Vince was named on 2 February and also intensified to a Category 3 on the Australian cyclone scale before exiting BoM area of responsibility on 4 February. February started with Tropical Lows 16U and 19U, though both disturbances exited the basin and entered the [[Fiji Meteorological Service]] area of responsibility. Meanwhile, the BoM designated Tropical Low 18U on 7 February, which was named ''Zelia'' on 11 February. Two days later, Zelia underwent [[rapid intensification]] due to warm sea surface temperatures and relatively low wind shear. At 00:00 UTC 13 February, Zelia intensified to a Category 4 severe tropical cyclone and later to Category 5 intensity.<ref name="C4 Zelia"/> Afterward, the cyclone stalled and underwent an [[eyewall replacement cycle]] (EWRC), which ended its rapid intensification phase. Radar imagery showed an EWRC, which was later completed before landfall near [[De Grey, Western Australia|De Grey]], northeast of [[Port Hedland, Western Australia|Port Hedland]].<ref name="Zelia EWRC"/>
On 18 February, the Bureau of Meteorology designated Tropical Low 21U in the eastern side of the Indian Ocean. BOM later named the system Tropical Cyclone Bianca. On 20 February, a tropical low was spotted by the Bureau of Meteorology in the Coral Sea. The disturbance, initially designated by the agency as 22U, was noted to likely develop into a tropical cyclone over the next several days. Two days later, BOM upgraded the system to a category 1, with the name Alfred being assigned to it. On 25 February, Bianca peaked as a Category 4 severe tropical cyclone on the Australian cyclone scale and Category 3 on the SSHWS scale. Afterward, increasing wind shear and cooler sea surface temperatures caused the storm to rapidly weaken, dissipating on 27 February. Over the next couple of days, Alfred continued to gradually move to the east, and was upgraded to a Category 2 tropical cyclone in the Australian scale at 16:00 AEST on 24 February. As Alfred turned south, it intensified to Category 3 status on 26 February at 22:00 AEST. The next day, the BOM further upgraded Alfred to a Category 4 cyclone, with a small eye appearing on visible satellite imagery. Later that night, an eyewall replacement cycle (ERC) occurred, prompting Alfred to fluctuate between Categories 3 and 4 on 1 March, before further weakening down to a Category 1 the following day. The cyclone then restrengthened slightly to Category 2 status by 3 March, before being downgraded to Category 1 intensity on 8 March. Alfred made landfall at Moreton Island on 01:00 AEST March 8 as a Category 1 tropical cyclone, and was downgraded to a tropical low five hours later.<ref>{{cite web |author=|date=2025-02-25|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250225.archive.shtml|website=Bureau of Meteorology|access-date=2025-02-25}}</ref>

===Late season activity===
[[File:Cyclone Errol explosively intensifying.gif|thumb|Timelapse of Cyclone Errol explosively intensifying from Category 1 to Category 5 in less than 16 hours.]]
Tropical Low 23U formed on 4 March before exiting the basin on 8 March. The system later intensified into Tropical Storm Ivone in the South-West Indian Ocean. Tropical Cyclone 25U formed on 17 March before dissipating on 21 March. Tropical Low 27U formed on 22 March and strengthened into Tropical Cyclone Courtney three days later. Afterward, Courtney intensified to a Category 5 cyclone on the Australian cyclone scale before entering the South-West Indian Ocean on 29 March. Tropical Cyclone Dianne formed near North Australia on 28 March and made landfall near Derby on 29 March. On 8 April, Tropical Low 29U formed in the Arafura Sea. Three days later, JTWC designated ''Tropical Cyclone 29S''. Later on 15 April, 29S was designated as Errol by BoM. Shortly after the designation, the cyclone explosively intensified to a powerful Category 5 equivalent cyclone with peak 1-minute sustained winds of 160 mph and 919 hPa according to the JTWC. Tropical Low 30U formed in the Arafura Sea on 13 April. On 18 April, JTWC designated 30U as 31P. It was expected to strengthen, but wind shear soon caused it to dissipate on 23 April.

===Off-season===
On 9 May 2025, Tropical Low 33U formed near Papua New Guinea. During 11 May, this system was upgraded to a tropical storm by the JTWC and designated ''32P''. On the same date, Tropical Low 34U formed near the [[Solomon Islands]]. 33U dissipated the next day.

On 20 February, a tropical low was spotted by the [[Bureau of Meteorology]] (BOM) in the [[Coral Sea]]. The disturbance, initially designated by the agency as ''22U'', was noted to likely develop into a tropical cyclone over the next several days.<ref>{{Cite news |first=Gabrielle |last=Becerra Mellet |date=20 February 2025 |title=Cyclone likely to form off Queensland coast, BOM says |url=https://www.abc.net.au/news/2025-02-21/queensland-weather-cyclone-developing-bom/104960468 |access-date=3 March 2025 |work=ABC News}}</ref> Two days later, the [[Joint Typhoon Warning Center]] (JTWC) – which unofficially monitors all tropical cyclone basins, including the Australian region – upgraded the system to a tropical storm on the [[Saffir–Simpson scale]] (SSHWS). Initially, the BOM did not immediately follow suit and kept it as a tropical low; however, around 16:20 AEST, BOM upgraded the system to a category 1, with the name ''Alfred'' being assigned to it. Over the next couple of days, the storm continued to gradually move to the east, and was upgraded to a category 2 tropical cyclone in the Australian scale at 16:00 AEST on 24 February. As Alfred then turned south, it also continued to intensify, attaining category 3 status on 26 February at 22:00 AEST. The next day, the BOM further upgraded Alfred to a category 4 cyclone as a small eye appeared on visible satellite imagery. Later that night, an [[eyewall replacement cycle]] (ERC) occurred, prompting Alfred to fluctuate between Categories 3 and 4 on 1 March, before further weakening down to a Category 1 the following day. The cyclone then restrengthened slightly to category 2 status by 3 March, before being downgraded to a Category 1 on 8 March.<ref name=":0">{{Cite news |date=2025-03-08 |title=Flooding risk for Queensland, northern NSW despite Alfred downgrade |url=https://www.abc.net.au/news/2025-03-08/threat-of-flooding-queensland-northern-nsw-risk-cyclone-alfred/105027148 |access-date=2025-03-08 |work=ABC News |language=en-AU}}</ref>

Beginning on 3 March, watches and warnings were issued in [[South East Queensland]] (SEQ) – including Brisbane – as Alfred posed a notable risk to the area, with all major forecast models having predicted an SEQ landfall between 6 and 8 March.

Tropical Low 25U formed in the South Indian Ocean on 17 March. On 18 March, Joint Typhoon Warning Center marked system as Tropical Cyclone 26S. 25U dissipated on 21 March and its remnants were absorbed by Tropical Low 27U, which would become Tropical Cyclone Courtney.

In late April, the BoM announced that based on post event reanalysis, Tropical Low 25U briefly reached tropical cyclone (TC) intensity near the Cocos Islands on 19 March, and thus has been reassigned as an unnamed tropical cyclone.<ref>{{cite web |author=|date=2025-04-29|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250429.archive.shtml|website=Bureau of Meteorology|access-date=2025-04-30}}</ref>

Tropical Low 27U formed on 22 March, located north-west of Australia. The system intensified into a category 1 tropical cyclone on 25 March, receiving the name Courtney. Courtney strengthened for a few days, reaching its peak intensity as a Category 5 tropical cyclone on 29 March. It moved into the South-West Indian Ocean later that day, still at peak intensity.<ref>{{cite web |author=|date=2025-04-01|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250401.archive.shtml|website=Bureau of Meteorology|access-date=2025-04-04}}</ref>

Tropical Low 28U formed north of Western Australia on 25 March. On 28 March, Joint Typhoon Warning Center marked system as Tropical Cyclone 28S. Tropical Low 28U gained gale force winds in the northern quadrants of the storm. A few hours later the Bureau of Meteorology named it Dianne on 28 March. It peaked at 85km/h. Dianne made landfall just east of Cockatoo Island in the Western Australia region a short time after being named.

130 mm of rain fell in Derby, causing street flooding. However, there were no reports of significant damage.<ref>{{Cite news |date=2025-03-29 |title='You can almost surf on it': Locals welcome deluge from cyclone in WA's north |url=https://www.abc.net.au/news/2025-03-29/ex-tropical-cyclone-dianne-brings-flooding-risk-to-wa-kimberley/105112090 |access-date=2025-03-29 |work=ABC News |language=en-AU}}</ref>

Errol formed on 9 April as Tropical Low 29U,<ref>{{cite web |author=|date=2025-04-08|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250408.archive.shtml|website=Bureau of Meteorology|access-date=2025-04-08}}</ref> and fluctuated from a Tropical Low to Category 1 from 12 April to 14 April. Starting late on 15 April, Errol begun a period of explosive deepening; 1-minute sustained winds increased from 100 km/h (65 mph) to {{cvt|260|km/h|mph|round=5|abbr=on}} in 24 hours and {{cvt|120|km/h|mph|round=5|abbr=on}} to 220 km/h (140 mph) in 12 hours, and the JTWC described it as 'explosive and extreme rapid intensification'. Early on 16 April, it reached its peak intensity as a Category 5 equivalent tropical cyclone with 1-minute sustained winds of {{convert|140|kn|km/h mph|round=5|order=out|abbr=on|sortable=on}}, according to JTWC, while the BOM estimated 10-minute sustained winds of {{convert|110|kn|km/h mph|round=5|order=out|abbr=on|sortable=on}} which made it a Category 5 severe tropical cyclone. On 16 April, Errol began to turn south, and on 17 April, as Errol took a sharp turn southeast-east, wind shear rapidly increased to 50 knots, causing Errol to rapidly weaken. It made landfall south of Kuri Bay on 18 April as a tropical low.<ref>{{cite web |author=|date=2025-04-22|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250422.archive.shtml|website=Bureau of Meteorology|access-date=2025-04-22}}</ref> After landfall, the BoM ceased advisories on the system as it fell below warning criteria.

Errol was a small tropical cyclone that brought heavy rain to the Northern Kimberley coast including Derby and Kalumburu on 18 and 19 April.<ref>{{Cite news |date=2025-04-18 |title=Ex-cyclone Errol 'a dodged bullet' as it crosses Kimberley as tropical low |url=https://www.abc.net.au/news/2025-04-19/ex-cyclone-errol-kimberley-tropical-low-impact-severe-weather/105192150 |access-date=2025-04-19 |work=ABC News |language=en-AU}}</ref> Kalumburu received 160.8 mm of rainfall in the 24 hours to 9 am on 19 April. Errol is the latest tropical cyclone to form or move into the Australian region since [[2021–22 Australian region cyclone season#Tropical Cyclone Karim|Cyclone Karim]] which formed on 7 May 2022. However, no major damage was recorded.

The '''2025 Pacific hurricane season''' is the current [[Pacific hurricane season]] for the [[Northern Hemisphere]]. The season officially began on May 15, 2025, and ends on November 30, 2025. For the Central Pacific ([[140th meridian west|140ºW]] to [[180th meridian|180º]]), the season begins on June 1, 2025, and ends on November 30, 2025. Those dates, adopted by convention, describe the period in which most subtropical or [[tropical cyclogenesis]] occurs in the [[Pacific Ocean]].

In advance of each [[Pacific hurricane]] season, [[Tropical cyclone seasonal forecasting|forecasts of hurricane activity]] are issued by forecasters from the United States [[National Oceanic and Atmospheric Administration]] (NOAA)'s [[Climate Prediction Center]], and [[Mexico]]'s [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN). The forecasts include weekly and monthly changes in significant factors that help determine the amount of tropical storms, hurricanes, and major hurricanes within a particular season.<ref name="Background"/>

According to NOAA, the average Pacific hurricane season between 1991 and 2020 contained about 15 named storms, 8 hurricanes and 4 major hurricanes (Category 3 and higher), as well as an [[Accumulated Cyclone Energy|accumulated cyclone energy]] (ACE) index of 80–115 units. Broadly speaking, ACE is the measure of the power of a tropical or [[subtropical cyclone]] multiplied by the length of time it existed. ACE is only calculated for full advisories on specific tropical or subtropical cyclones reaching wind speeds of 39 mph (63 km/h) or higher. NOAA typically describes a season as above-average, average, or below-average depending on the cumulative ACE index, but the number of tropical storms, hurricanes or major hurricanes can also be considered.<ref name="Background"/>

On May 7, 2025, the [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN) issued its first outlook for the Pacific hurricane season, forecasting an above average season with 16–20 named storms, 8–11 hurricanes, and 4–6 major hurricanes.<ref name="SMN"/> On May 22, the [[National Oceanic and Atmospheric Administration]] (NOAA) released its outlook for the eastern Pacific, which calls for an above-average season with 12 to 18 named storms, 5 to 10 hurricanes, and 2 to 5 major hurricanes, citing a continued neutral phase, the unlikelihood of an [[El Niño]], and the possibility of [[La Niña]] in the summer.<ref name="NOAA"/> This increases vertical wind shear in the basin and slightly reduces sea surface temperatures, thus favoring mild to moderate tropical cyclone activity. Furthermore, many global computer models predicted a negative [[Pacific decadal oscillation]] (PDO), a phase of a multi-decadal cycle that favored the continuation of much warmer-than-average sea surface temperatures, which had been occurring since [[2021 Pacific hurricane season|2021]], unlike the 1991-2020 period, which generally featured below-normal activity.<ref name="Background"/>

For storms that form in the North Pacific from 140°W to the [[International Date Line]], the names come from a series of four rotating lists. Names are used one after the other without regard to year, and when the bottom of one list is reached, the next named storm receives the name at the top of the next list.<ref name="ENP CNP"/> Any named storms that form within the area in 2025 will be listed below. Named storms in the table above that cross into the area during the season are noted (*).

==Season effects==
The following is a table which will include all of the storms that form in the 2025 Pacific hurricane season. It will include their duration, names, intensities, areas affected, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2025 USD.

In advance of each [[Pacific hurricane]] season, [[Tropical cyclone seasonal forecasting|forecasts of hurricane activity]] are issued by forecasters from the United States [[National Oceanic and Atmospheric Administration]] (NOAA)'s [[Climate Prediction Center]], and [[Mexico]]'s [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN). The forecasts include weekly and monthly changes in significant factors that help determine the amount of tropical storms, hurricanes, and major hurricanes within a particular season.<ref name="Background"/>

According to NOAA, the average Pacific hurricane season between 1991 and 2020 contained about 15 named storms, 8 hurricanes and 4 major hurricanes (Category 3 and higher), as well as an [[Accumulated Cyclone Energy|accumulated cyclone energy]] (ACE) index of 80–115 units. Broadly speaking, ACE is the measure of the power of a tropical or [[subtropical cyclone]] multiplied by the length of time it existed. ACE is only calculated for full advisories on specific tropical or subtropical cyclones reaching wind speeds of 39 mph (63 km/h) or higher. NOAA typically describes a season as above-average, average, or below-average depending on the cumulative ACE index, but the number of tropical storms, hurricanes or major hurricanes can also be considered.<ref name="Background"/>

On May 7, 2025, the [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN) issued its first outlook for the Pacific hurricane season, forecasting an above average season with 16–20 named storms, 8–11 hurricanes, and 4–6 major hurricanes.<ref name="SMN"/> On May 22, the National Oceanic and Atmospheric Administration (NOAA) released its outlook for the eastern Pacific, which calls for an above-average season with 12 to 18 named storms, 5 to 10 hurricanes, and 2 to 5 major hurricanes,

On May 22, the [[National Oceanic and Atmospheric Administration]] (NOAA) released its outlook for the eastern Pacific, which calls for an above-average season with 12 to 18 named storms, 5 to 10 hurricanes, and 2 to 5 major hurricanes, citing a continued neutral phase, the unlikelihood of an [[El Niño]], and the possibility of [[La Niña]] in the summer.<ref name="NOAA"/> This increases vertical wind shear in the basin and slightly reduces sea surface temperatures, thus favoring mild to moderate tropical cyclone activity. Furthermore, many global computer models predicted a negative [[Pacific decadal oscillation]] (PDO), a phase of a multi-decadal cycle that favored the continuation of much warmer-than-average sea surface temperatures, which had been occurring since [[2021 Pacific hurricane season|2021]], unlike the 1991-2020 period, which generally featured below-normal activity.<ref name="Background"/>

For storms that form in the North Pacific from 140°W to the [[International Date Line]], the names come from a series of four rotating lists. Names are used one after the other without regard to year, and when the bottom of one list is reached, the next named storm receives the name at the top of the next list.<ref name="ENP CNP"/> Any named storms that form within the area in 2025 will be listed below. Named storms in the table above that cross into the area during the season are noted (*).

==Season effects==
The following is a table which will include all of the storms that form in the 2025 Pacific hurricane season. It will include their duration, names, intensities, areas affected, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2025 USD.

'''Hurricane Alex''' was the first [[tropical cyclone]] of the [[2010 Atlantic hurricane season]], and a rare June [[Atlantic hurricane]]. Originating from an area of disturbed weather on June 25, 2010, it slowly developed in the western [[Caribbean Sea]] and struck [[Belize]] as a strong tropical storm. After entering the [[Gulf of Mexico]], Alex became very large and encountered conditions favorable for gradual development. Early on June 30, the cyclone attained hurricane status as it approached northeastern Mexico, the first June hurricane in the Atlantic basin since [[Hurricane Allison (1995)|Hurricane Allison]] in 1995, and the storm [[rapidly intensified]] just off the coast of [[Tamaulipas]]. Alex made [[landfall]] near [[Soto la Marina]] as a [[List of Category 2 Atlantic hurricanes|Category 2 hurricane]] on the [[Saffir-Simpson Hurricane Scale|Saffir-Simpson Hurricane Wind Scale]]. Alex rapidly weakened after landfall, with the storm losing its tropical status on July 2, before fully dissipating on July 6.<ref name="WPC report" />

Alex caused the deaths of at least 51 people along its path, and produced over $1.5 billion (2010 [[USD]]) in damage. The precursor of the hurricane produced substantial rainfall across the [[Greater Antilles]], causing one death in the [[Dominican Republic]]. Fourteen people were killed in [[Central America]] as a result of flooding during the first landfall of Alex. In Mexico, the storm's outer [[rainband]]s killed three people in [[Acapulco]], one person in [[Oaxaca]], and another in [[Chiapas]]. At its final landfall, Alex caused at least fifteen deaths in [[Nuevo León]], eight in [[Coahuila]], six in [[Guanajuato]], and one in both [[Tamaulipas]] and [[San Luis Potosí]]; an additional twenty persons were reported missing.

Alex triggered widespread power outages throughout northeastern Mexico and southern Texas. Damage was most evident in the [[Monterrey Metropolitan area|Monterrey metropolitan area]], which faced what Nuevo León governor [[Rodrigo Medina|Rodrigo Medina de la Cruz]] described as, "the worst weather phenomenon in its history."<ref name="EFE Mty impact"/> Following Alex's final [[landfall]], a state of emergency was declared for most of Nuevo León, portions of Tamaulipas, and Texas. Widespread flooding from the storm affected 500,000 people throughout northeast Mexico, and ruined over {{convert|200000|ha|acre|sigfig=1}} of crops in the region, equivalent to 11% of the region's total farmland. Despite the significant damage and death toll, the name ''Alex'' was not retired following the season.

As floodwaters receded from the Pesquería River in [[Escobedo, Nuevo León]], the remnants of a 15,000-year-old [[mammoth]] were discovered by local residents. It is believed that the remains were carried from the state of Coahuila to Escobedo by the floodwaters. The remnants were identified and dated by personnel from the [[Instituto Nacional de Antropología e Historia]].<ref>{{cite news| last=Staff writer| title=Encuentran mamut muerto en río Pesquería| url=http://www.milenio.com/cdb/doc/noticias2011/7c954b2a681dd8c89db2c26caf91095c| access-date=2010-07-06| newspaper=[[Milenio]]| date=2010-07-05| language=es| archive-date=2023-02-04| archive-url=https://web.archive.org/web/20230204142659/https://www.milenio.com/cdb/doc/noticias2011/7c954b2a681dd8c89db2c26caf91095c| url-status=live}}</ref>

=== Records ===
Alex equaled the lowest recorded barometric pressure for a June Atlantic hurricane set by [[Hurricane Audrey]] in [[1957 Atlantic hurricane season|1957]]. It was also the first June Atlantic hurricane since [[Hurricane Allison (1995)|Hurricane Allison]] in [[1995 Atlantic hurricane season|1995]], and the strongest in terms of sustained wind speed since [[Hurricane Alma (1966)|Hurricane Alma]] in [[1966 Atlantic hurricane season|1966]].{{hurdat}}

The '''2024–25 Australian region cyclone season''' was the most active season in the Australian region since [[2005–06 Australian region cyclone season|2005–06]]. This season also had the highest amount of severe tropical cyclones since 2005-06, as well as being the first non-below average season since [[2018–19 Australian region cyclone season|2018–19]]. The season recorded an average amount of tropical cyclones, an above average amount of tropical lows. The season officially started on 1 November 2024 and ended on 30 April 2025, however, a tropical cyclone could form at any time between 1 July 2024 and 30 June 2025 and would count towards the season total. During the season, tropical cyclones are officially monitored by one of the three tropical cyclone warning centres (TCWCs) for the region which are operated by the [[Australian Bureau of Meteorology]], National Weather Service of [[Papua New Guinea]] and the [[Indonesian Agency for Meteorology, Climatology and Geophysics]]. The United States [[Joint Typhoon Warning Center]] (JTWC) and other national meteorological services including [[Météo-France]] and the [[Fiji Meteorological Service]] will also monitor the basin during the season.

===Early season activity===
The season officially started on 1 November, 2024. On 14 November, the [[Bureau of Meteorology]] (BoM) noted that a tropical low may form west of Sumatra.<ref name="Sumatra TL"/> A westerly wind shear enhanced the disturbance's development. Despite moderate to high wind shear displacing deep convection, the tropical low further developed and the Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert. <ref name="TCFA 04U"/> On 28 November, the BoM named Tropical Cyclone ''Robyn''. The storm officially peaked as a high-end tropical storm before increasing wind shear caused the storm to dissipate. On 4 December, Tropical Low 04U formed off the coast of [[Java]] and headed west before dissipating on 11 December. Unfortunately, the disturbance caused landslides and floods, killing eleven people and leaving seven missing.<ref name="TL 04U Deaths"/><ref name="04U Deaths"/> The rest of December had Tropical Lows 02U, 06U, 07U, and 08U. Tropical Low 07U formed southeast of the [[Cocos (Keeling) Islands|Cocos Islands]] and JTWC designated it as a tropical storm. 08U later became Category 3 [[Cyclone Dikeledi]] in the Southwest Indian Ocean.

===Peak season activity===
The first half of January had Tropical Lows 09U and 10U. The latter half had Sean, 13U, Taliah, and Vince. On 17 January, the BoM designated Tropical Low 11U, which absorbed 10U, and later named ''Sean'' on 19 January. A day later, the storm rapidly intensified to a Category 4 major cyclone on the Australian cyclone scale, possessing a distinct eye and intense winds.<ref name="C4 Sean"/> Sean dissipated a couple days later. The cyclone caused heavy rainfall and gale-force winds across portions of Western Australia. A record amount of rain fell in [[Karratha, Western Australia|Karratha]], with 274.4 mm recorded within 24 hours on 20 January.<ref name="Sean rainfall"/> Tropical Low 13U briefly tracked along the coast of Queensland and flooding killed a 63 year old woman.<ref name="13U Fatality"/> On 31 January, the BoM designated Tropical Lows 14U and 15U, which were later named ''Taliah'' and ''Vince''. After dealing with moderate wind shear, on 3 February, Taliah peaked as a Category 3 severe tropical cyclone on the Australian cyclone scale and Category 2 on the SSHWS scale.<ref name="Cyclone Taliah"/> Taliah exited the basin on 12 February. Vince was named on 2 February and also intensified to a Category 3 on the Australian cyclone scale before exiting BoM area of responsibility on 4 February. February started with Tropical Lows 16U and 19U, though both disturbances exited the basin and entered the [[Fiji Meteorological Service]] area of responsibility. Meanwhile, the BoM designated Tropical Low 18U on 7 February, which was named ''Zelia'' on 11 February. Two days later, Zelia underwent [[rapid intensification]] due to warm sea surface temperatures and relatively low wind shear. At 00:00 UTC 13 February, Zelia intensified to a Category 4 severe tropical cyclone and later to Category 5 intensity.<ref name="C4 Zelia"/> Afterward, the cyclone stalled and underwent an [[eyewall replacement cycle]] (EWRC), which ended its rapid intensification phase. Radar imagery showed an EWRC, which was later completed before landfall near [[De Grey, Western Australia|De Grey]], northeast of [[Port Hedland, Western Australia|Port Hedland]].<ref name="Zelia EWRC"/>
On 18 February, the Bureau of Meteorology designated Tropical Low 21U in the eastern side of the Indian Ocean. BOM later named the system Tropical Cyclone Bianca. On 20 February, a tropical low was spotted by the Bureau of Meteorology in the Coral Sea. The disturbance, initially designated by the agency as 22U, was noted to likely develop into a tropical cyclone over the next several days. Two days later, BOM upgraded the system to a category 1, with the name Alfred being assigned to it. On 25 February, Bianca peaked as a Category 4 severe tropical cyclone on the Australian cyclone scale and Category 3 on the SSHWS scale. Afterward, increasing wind shear and cooler sea surface temperatures caused the storm to rapidly weaken, dissipating on 27 February. Over the next couple of days, Alfred continued to gradually move to the east, and was upgraded to a Category 2 tropical cyclone in the Australian scale at 16:00 AEST on 24 February. As Alfred turned south, it intensified to Category 3 status on 26 February at 22:00 AEST. The next day, the BOM further upgraded Alfred to a Category 4 cyclone, with a small eye appearing on visible satellite imagery. Later that night, an eyewall replacement cycle (ERC) occurred, prompting Alfred to fluctuate between Categories 3 and 4 on 1 March, before further weakening down to a Category 1 the following day. The cyclone then restrengthened slightly to Category 2 status by 3 March, before being downgraded to Category 1 intensity on 8 March. Alfred made landfall at Moreton Island on 01:00 AEST March 8 as a Category 1 tropical cyclone, and was downgraded to a tropical low five hours later.<ref>{{cite web |author=|date=2025-02-25|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250225.archive.shtml|website=Bureau of Meteorology|access-date=2025-02-25}}</ref>

===Late season activity===
[[File:Cyclone Errol explosively intensifying.gif|thumb|Timelapse of Cyclone Errol explosively intensifying from Category 1 to Category 5 in less than 16 hours.]]
Tropical Low 23U formed on 4 March before exiting the basin on 8 March. The system later intensified into Tropical Storm Ivone in the South-West Indian Ocean. Tropical Cyclone 25U formed on 17 March before dissipating on 21 March. Tropical Low 27U formed on 22 March and strengthened into Tropical Cyclone Courtney three days later. Afterward, Courtney intensified to a Category 5 cyclone on the Australian cyclone scale before entering the South-West Indian Ocean on 29 March. Tropical Cyclone Dianne formed near North Australia on 28 March and made landfall near Derby on 29 March. On 8 April, Tropical Low 29U formed in the Arafura Sea. Three days later, JTWC designated ''Tropical Cyclone 29S''. Later on 15 April, 29S was designated as Errol by BoM. Shortly after the designation, the cyclone explosively intensified to a powerful Category 5 equivalent cyclone with peak 1-minute sustained winds of 160 mph and 919 hPa according to the JTWC. Tropical Low 30U formed in the Arafura Sea on 13 April. On 18 April, JTWC designated 30U as 31P. It was expected to strengthen, but wind shear soon caused it to dissipate on 23 April.

===Off-season===
On 9 May 2025, Tropical Low 33U formed near Papua New Guinea. During 11 May, this system was upgraded to a tropical storm by the JTWC and designated ''32P''. On the same date, Tropical Low 34U formed near the [[Solomon Islands]]. 33U dissipated the next day.

On 20 February, a tropical low was spotted by the [[Bureau of Meteorology]] (BOM) in the [[Coral Sea]].

Initially, the BOM did not immediately follow suit and kept it as a tropical low; however, around 16:20 AEST, BOM upgraded the system to a category 1, with the name ''Alfred'' being assigned to it. Over the next couple of days, the storm continued to gradually move to the east, and was upgraded to a category 2 tropical cyclone in the Australian scale at 16:00 AEST on 24 February. As Alfred then turned south, it also continued to intensify, attaining category 3 status on 26 February at 22:00 AEST. The next day, the BOM further upgraded Alfred to a category 4 cyclone as a small eye appeared on visible satellite imagery. Later that night, an [[eyewall replacement cycle]] (ERC) occurred, prompting Alfred to fluctuate between Categories 3 and 4 on 1 March, before further weakening down to a Category 1 the following day. The cyclone then restrengthened slightly to category 2 status by 3 March, before being downgraded to a Category 1 on 8 March.<ref name=":0">{{Cite news |date=2025-03-08 |title=Flooding risk for Queensland, northern NSW despite Alfred downgrade |url=https://www.abc.net.au/news/2025-03-08/threat-of-flooding-queensland-northern-nsw-risk-cyclone-alfred/105027148 |access-date=2025-03-08 |work=ABC News |language=en-AU}}</ref>

The '''2025 Pacific hurricane season''' is the current [[Pacific hurricane season]] for the [[Northern Hemisphere]]. The season officially began on May 15, 2025, and ends on November 30, 2025. For the Central Pacific ([[140th meridian west|140ºW]] to [[180th meridian|180º]]), the season begins on June 1, 2025, and ends on November 30, 2025. Those dates, adopted by convention, describe the period in which most subtropical or [[tropical cyclogenesis]] occurs in the [[Pacific Ocean]]. The [[National Hurricane Center]] (NHC) will begin issuing routine Tropical Weather Outlooks for east of 140ºW on May 15, 2025, and the [[Central Pacific Hurricane Center]] will begin issuing routine Tropical Weather Outlooks for west of 140ºW and east of 180º on June 1, 2025, both on the same date as the seasons starting dates.

In advance of each [[Pacific hurricane]] season, [[Tropical cyclone seasonal forecasting|forecasts of hurricane activity]] are issued by forecasters from the United States [[National Oceanic and Atmospheric Administration]] (NOAA)'s [[Climate Prediction Center]], and [[Mexico]]'s [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN). The forecasts include weekly and monthly changes in significant factors that help determine the amount of tropical storms, hurricanes, and major hurricanes within a particular season.<ref name="Background"/>

According to NOAA, the average Pacific hurricane season between 1991 and 2020 contained about 15 named storms, 8 hurricanes and 4 major hurricanes (Category 3 and higher), as well as an [[Accumulated Cyclone Energy|accumulated cyclone energy]] (ACE) index of 80–115 units. Broadly speaking, ACE is the measure of the power of a tropical or [[subtropical cyclone]] multiplied by the length of time it existed. ACE is only calculated for full advisories on specific tropical or subtropical cyclones reaching wind speeds of 39 mph (63 km/h) or higher. NOAA typically describes a season as above-average, average, or below-average depending on the cumulative ACE index, but the number of tropical storms, hurricanes or major hurricanes can also be considered.<ref name="Background"/>

On May 7, 2025, the [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN) issued its first outlook for the Pacific hurricane season, forecasting an above average season with 16–20 named storms, 8–11 hurricanes, and 4–6 major hurricanes.<ref name="SMN"/>

For storms that form in the North Pacific from 140°W to the [[International Date Line]], the names come from a series of four rotating lists. Names are used one after the other without regard to year, and when the bottom of one list is reached, the next named storm receives the name at the top of the next list.<ref name="ENP CNP"/> Any named storms that form within the area in 2025 will be listed below. Named storms in the table above that cross into the area during the season are noted (*).

==Season effects==
The following is a table which will include all of the storms that form in the 2025 Pacific hurricane season. It will include their duration, names, intensities, areas affected, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2025 USD.

The '''2024 Atlantic hurricane season''' was a very active and extremely destructive [[Atlantic hurricane season]] that became the third-costliest on record, behind only [[2017 Atlantic hurricane season|2017]] and [[2005 Atlantic hurricane season|2005]]. The season featured 18 [[Tropical cyclone naming|named storms]], 11 hurricanes, and 5 [[major hurricane]]s; it was also the first since [[2019 Atlantic hurricane season|2019]] to feature multiple [[List of Category 5 Atlantic hurricanes|Category 5 hurricanes]]. Additionally, the season had the highest [[accumulated cyclone energy]] (ACE) rating since [[2020 Atlantic hurricane season|2020]], with a value of 161.6 units. The season officially began on June 1, and ended on November 30. These dates, adopted by convention, have historically described the period in each year when most subtropical or [[tropical cyclogenesis]] occurs in the [[Atlantic Ocean]].

The first system, [[Tropical Storm Alberto (2024)|Tropical Storm Alberto]], developed on June 19, made landfall near [[Tampico, Tamaulipas]] the next day. Afterward, two storms formed in quick succession at the end of June, with the first, [[Hurricane Beryl]], being a rare June major hurricane, the earliest Category 5 Atlantic hurricane on record, and only the second recorded in July. Next came [[Tropical Storm Chris (2024)|Tropical Storm Chris]], which formed on the last day of June and quickly made landfall in [[Veracruz]]. Activity then quieted down across the basin for most of July after Beryl dissipated, with no new tropical cyclones forming due to the presence of the [[Saharan air layer]] (SAL) across much of the Atlantic. In early August, [[Hurricane Debby]] developed in the [[Gulf of Mexico]] before making landfall in [[Florida]] and [[South Carolina]]. Shortly thereafter came [[Hurricane Ernesto (2024)|Hurricane Ernesto]], which impacted the [[Lesser Antilles]], [[Puerto Rico]], and [[Bermuda]] in mid-August. After an unusual lull in activity in late August and early September, [[Hurricane Francine]] formed in the western Gulf of Mexico, then made landfall in [[Louisiana]].

Activity dramatically increased in late September with several strong storms developing. [[Hurricane Helene]] developed over the western Caribbean before moving toward the Big Bend region of Florida and making landfall there on September 26 at Category 4 strength, causing catastrophic flooding and numerous fatalities over central [[Appalachia]]. [[Hurricane Kirk (2024)|Hurricane Kirk]] formed soon after and rapidly intensified into a Category 4 hurricane in the Eastern Atlantic before striking Europe as a post-tropical cyclone. October was also very active, with four named storms developing during the month, of which all but one were hurricanes. The strongest, [[Hurricane Milton]], formed in the Gulf of Mexico and explosively intensified into the second Category 5 hurricane of the season; it was also the strongest [[Tropical cyclones in 2024|tropical cyclone worldwide in 2024]].<ref>{{cite web|title=Category 5 Super Typhoon Man-yi hits the Philippines|last1=Masters|first1=Jeff|last2=Henson|first2=Bob|date=November 16, 2024|url=https://yaleclimateconnections.org/2024/11/category-5-super-typhoon-man-yi-hits-the-philippines/|publisher=Yale Climate Connection|location=New Haven, Connecticut|access-date=November 16, 2024}}</ref> Milton later made landfall near [[Siesta Key, Florida|Siesta Key]], Florida, on October 9, as a [[Category 3 hurricane]]. In mid-October, [[Tropical Storm Nadine (2024)|Tropical Storm Nadine]] and [[Hurricane Oscar (2024)|Hurricane Oscar]] formed in quick succession, with the former quickly making landfall in [[Belize]] while the latter rapidly intensified into a Category 1 hurricane, and achieved the smallest hurricane-force wind field on record in the Atlantic. It made landfall in [[Inagua]] and [[Cuba]]. In early November, [[Hurricane Rafael]] made landfall in western Cuba at Category 3 strength, and later attained sustained winds of {{cvt|105|kn|mph km/h|order=out|round=5}}, tying 1985's [[Hurricane Kate (1985)|Hurricane Kate]] as the strongest November hurricane on record in the Gulf of Mexico.<ref name="tied">{{cite news|author=Patrick Smith|title=Hurricane Rafael moves across Gulf of Mexico as a rare major November storm while Cuba recovers|url=https://www.nbcnews.com/weather/hurricanes/hurricane-rafael-moves-gulf-mexico-rare-major-november-storm-cuba-reco-rcna179273|publisher=NBC News|language=en-US|date=November 8, 2024|access-date=November 8, 2024}}</ref> In mid-November, the last system, [[Tropical Storm Sara]], moved very slowly along the coast of [[Honduras]], before making landfall in Belize, while producing widespread heavy rainfall resulting in severe flash flooding and mudslides across northern Central America.

In advance of, and during, each hurricane season, several [[Tropical cyclone seasonal forecasting|forecasts of hurricane activity]] are issued by national meteorological services, scientific agencies, and noted hurricane experts. These include forecasters from the United States [[National Oceanic and Atmospheric Administration]] (NOAA)'s [[Climate Prediction Center]], Tropical Storm Risk (TSR), the United Kingdom's [[Met Office]] (UKMO), and [[Colorado State University]] (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year.<ref name="Klotzbach et al. 2019">{{cite journal |last1=Klotzbach |first1=Philip |last2=Blake |first2=Eric |last3=Camp |first3=Joanne |last4=Caron |first4=Louis-Philippe |last5=Chan |first5=Johnny C.L. |last6=Kang |first6=Nam-Young |last7=Kuleshov |first7=Yuri |last8=Lee |first8=Sai-Ming |last9=Murakami |first9=Hiroyuki |last10=Saunders |first10=Mark |last11=Takaya |first11=Yuhei |last12=Vitart |first12=Frederic |last13=Zhan |first13=Ruifen |title=Seasonal Tropical Cyclone Forecasting |journal=Tropical Cyclone Research and Review |date=September 2019 |volume=8 |issue=3 |pages=134–149 |doi=10.1016/j.tcrr.2019.10.003 |doi-access=free|bibcode=2019TCRR....8..134K }}</ref>

According to NOAA and CSU, the average [[Atlantic hurricane season]] between 1991 and 2020 contained roughly 14 tropical storms, 7 hurricanes, 3 major hurricanes, and an [[accumulated cyclone energy]] (ACE) index of 72–111 units.<ref name="Background"/><ref name="YCCExtremely">{{cite web |last1=Masters |first1=Jeff |title=Forecasters predict an extremely active 2024 Atlantic hurricane season |url=https://yaleclimateconnections.org/2024/04/forecasters-predict-an-extremely-active-2024-atlantic-hurricane-season/ |publisher=Yale Climate Connections |access-date=June 1, 2024 |date=April 4, 2024 |archive-date=June 1, 2024 |archive-url=https://web.archive.org/web/20240601163314/https://yaleclimateconnections.org/2024/04/forecasters-predict-an-extremely-active-2024-atlantic-hurricane-season/ |url-status=live }}</ref> Broadly speaking, ACE is a measure of the power of a tropical or [[subtropical storm]] multiplied by the length of time it existed. It is only calculated for full advisories on specific tropical and subtropical systems reaching or exceeding wind speeds of {{cvt|39|mph}}. NOAA typically categorizes a season as above-average, average, or below-average based on the cumulative ACE index, but the number of tropical storms, hurricanes, and major hurricanes within a hurricane season is sometimes also considered.<ref name="Background" />

A [[Central American gyre]] resulted in the formation of convection over the [[Gulf of Tehuantepec]] on June 15. As the convective activity progressed northward over southeastern [[Mexico]] and exited into the [[Bay of Campeche]], an area of low pressure gradually developed on June 17 about {{convert|105|mi|km}} northwest of [[Ciudad del Carmen]], [[Mexico]]. The system gradually became better organized, though still remained rather broad, developing into Tropical Storm Alberto by 12:00 UTC on June 19. Under the influence of light vertical wind shear and warm sea surface temperatures, Alberto intensified up to landfall, attaining peak winds of {{cvt|45|kn|mph km/h|round=5|order=out}} and a minimum central pressure of {{cvt|992|mbar|inHg|sigfig=4}} by the morning of June 20.

On June 23, a [[tropical wave]] exited the west coast of Africa and entered the Atlantic. After initially moving westward with little development for a few days, the wave began organizing on June 27. By 12:00 UTC on the following day, Tropical Depression Two formed about {{convert|1380|mi|km|abbr=on|round=5}} east of [[Barbados]].<ref name="btcr">{{cite report|url=https://www.nhc.noaa.gov/data/tcr/AL022024_Beryl.pdf|title=Tropical Cyclone Report: Hurricane Beryl|author=Beven, John|author2=Fritz, Cody|author3=Alaka, Laura|date=May 1, 2025|publisher=National Hurricane Center|location=Miami, Florida|accessdate=May 7, 2025}}</ref> A strong [[subtropical ridge]] caused the depression to move generally west-northwestward through an unusually favorable environment for the time of year with warm [[sea surface temperature]]s (SST) and minimal [[wind shear]], consequently beginning a period of [[rapid intensification]].<ref>{{cite report|last=Cangialosi|first=John|title=Tropical Storm Beryl Discussion Number 2|url=https://www.nhc.noaa.gov/archive/2024/al02/al022024.discus.002.shtml?|publisher=National Hurricane Center|location=Miami, Florida|language=en-US|date=June 28, 2024|access-date=June 28, 2024}}</ref> The depression strengthened into Tropical Storm Beryl by 00:00 UTC June 29 and then into a hurricane about 24 hours thereafter. Beryl intensified into a Category 3 major hurricane around 12:00 UTC on June 30 and reached an intensity peak intensity as a Category 4 hurricane with sustained winds of 130 mph (215 km/h) six hours later. Beryl then underwent an [[eyewall replacement cycle]] and briefly weakened to a Category 3 hurricane early on July 1, but regained Category 4 strength six hours later once the cycle was completed. At 15:10 UTC the same day, Beryl made landfall in [[Carriacou]], [[Grenada]], with winds of 140 mph (220 km/h). After entering the Caribbean, the hurricane further intensified into a Category 5 hurricane early on July 2 and soon peaked with winds of 165 mph (270 km/h) and a minimum pressure of {{convert|932|mbar|inHg|abbr=on}}, recorded by a [[dropsonde]].<ref name="btcr"/>

Increasing wind shear caused Beryl to begin weakening later on July 2 as it passed well south of [[Hispaniola]], falling to Category 4 intensity by 18:00 UTC. Beryl's center passed close to the southern coast of [[Jamaica]] late on July 3 and early on July 4. Around 12:00 UTC on the latter date, the cyclone weakened to a Category 2 hurricane southeast of the [[Cayman Islands]]. Beryl briefly re-gained major hurricane status early on July 5, but quickly weakened back. At 11:00 UTC, the storm made landfall in Mexico near [[Tulum]], [[Quintana Roo]], as a Category 1 hurricane with winds of 90 mph (150 km/h). Beryl quickly fell to tropical storm status before emerging into the Gulf of Mexico later on July 5. Turning north-northwestward on July 7 due to a mid-latitude trough, the cyclone began re-intensifying significantly as wind shear decreased and moisture increased. Early on July 8, Beryl became a Category 1 hurricane, before making landfall near [[Matagorda, Texas]], at 08:40 UTC with winds of 90 mph (150 km/h). While passing over western [[Greater Houston]], Beryl weakened to a tropical storm at 18:00 UTC and turned northeastward. Around 00:00 UTC on July 9, the cyclone weakened to a tropical depression, approximately 12 hours before becoming [[Extratropical cyclone|extratropical]] over central [[Arkansas]]. The extratropical remnants crossed the [[Midwestern United States]] and southern [[Ontario]] before being absorbed over western [[New York (state)|New York]] by a frontal system on July 11.<ref name="btcr"/>

Continuously favorable conditions allowed the storm to intensify into a hurricane about 24 hours later as it moved northwestward and passed just offshore the Yucatán Peninsula. Helene then accelerated northeastward across the Gulf of Mexico due to a ridge and a deep-layer cut-off low-pressure area situated over the [[Tennessee Valley]] while expanding significantly and reaching major hurricane status late on September 26. At 03:10 UTC on the following day, Helene peaked as a Category 4 hurricane with maximum sustained winds of 140 mph (220 km/h) and a minimum pressure of {{convert|939|mbar|inHg|abbr=on}} as it struck Florida just east of the mouth of the [[Aucilla River]], based on data from a Texas Tech StickNet observation site located about halfway between the landfall point and [[Perry, Florida|Perry]]. Thus, the cyclone became the most intense to make landfall in the [[Big Bend (Florida)|Big Bend]] region of Florida since reliable records began.

{{main|Hurricane Milton}}
In mid-September, two African tropical waves and a low-level trough merged over the eastern Atlantic. Although disorganized upon reaching the Lesser Antilles on September 26, the wave began interacting with a CAG over the western Caribbean on September 29. This led to the formation of a low-level trough with two centers over the Gulf of Mexico. One center persisted, resulting in the development of Tropical Depression Fourteen about {{convert|155|mi|km|abbr=on|round=5}} east of [[Tampico]], [[Tamaulipas]], at 12:00 UTC on October 5. Strengthening into Tropical Storm Milton within six hours, the cyclone moved slowly eastward to east-southeastward over the next few days along the southern periphery of the mid-latitude westerlies. Milton underwent explosive intensification due to very warm waters and low-to-moderate wind shear, becoming a hurricane around 18:00 UTC on October 6 and then a major hurricane within 18 hours thereafter. At 20:00 UTC on October 7, the system peaked as a Category 5 hurricane with winds of 180 mph (285 km/h) and a minimum pressure of {{convert|895|mbar|inHg|abbr=on}}.<ref name="MTCR"/>

Early on October 8, the storm weakened to a Category 4 hurricane due to an [[eyewall replacement cycle]]; however, upon the cycle's completion, it quickly re-strengthened back to Category 5 intensity while turning northeastward in response to stronger deep-laying southwesterly flow. However, the next day, Milton weakened to a Category 4 hurricane and then to Category 3 intensity late on October 9 because of increasing wind shear. At 00:30 UTC on October 10, Milton struck near [[Siesta Key, Florida]], with {{convert|115|mph|km/h|abbr=on|round=5}} winds. Milton weakened over Florida and entered the Atlantic as a Category 1 hurricane, merging with a nearby frontal boundary. Around 18:00 UTC on October 10, it had transitioned into an [[Extratropical cyclone|extratropical low]]. The extratropical low gradually weakened, passed near Bermuda on October 11, and merged with a frontal zone on October 12.<ref name="MTCR"/>

On October 10, a tropical wave emerged into the Atlantic from the west coast of Africa. After remaining disorganized for several days due to dry air and moderate wind shear, a circulation began developing as the system passed north of the Lesser Antilles, and early on October 19, Tropical Storm Oscar formed approximately {{convert|180|mi|km|abbr=on|round=5}} north of Puerto Rico. In addition to very warm seas and light to moderate wind shear, the cyclone's small size allowed for quick intensification, with Oscar reaching hurricane status by 18:00 UTC. Hurricane-force winds less than {{convert|6|mi|km|abbr=on|sigfig=1}} from the center. Late on October 19, Oscar struck [[Grand Turk Island]] with winds of 85 mph (140 km/h). The system then turned southwestward due to low- to mid-level ridge over the eastern United States and passed near [[Inagua]] in the Bahamas on October 20, shortly before Oscar's barometric pressure fell to {{convert|984|mbar|inHg|abbr=on}}. At 22:00 UTC, Oscar made landfall in [[Baracoa]], located in the Cuban province of Guantánamo. Oscar quickly weakened to a tropical storm early on October 21 and slowed considerably due to collapsing steering currents, but re-emerged into the Atlantic several hours later. Late on October 22, Oscar degenerated into a trough over the central Bahamas, before soon being absorbed by a non-tropical low.<ref name="otcr">{{cite report|last=Papin|first=Philippe|title=Tropical Cyclone Report: Hurricane Oscar|date=March 11, 2025|url=https://www.nhc.noaa.gov/data/tcr/AL162024_Oscar.pdf|publisher=National Hurricane Center|location=Miami, Florida|access-date=April 6, 2025}}</ref>

On November 1, despite SSTs around {{Convert|20 to 22|C|F}}, convection and bands formed around the center due to an unstable environment. The storm had attained hybrid characteristics of a [[subtropical storm]]. Upon formation, Patty had winds of {{Convert|50|mph|km/h|abbr=on}}.

On October 26, the NHC began monitoring the southwestern Caribbean in anticipation of tropical development.<ref>{{cite report|last=Berg|first=Robbie|title=Tropical Weather Outlook|url=https://www.nhc.noaa.gov/archive/xgtwo/gtwo_archive.php?current_issuance=202410262323&basin=atl&fdays=7|date=October 26, 2024|publisher=National Hurricane Center|location=Miami, Florida|access-date=November 3, 2024}}</ref> Convection increased markedly in early November in association with a Central American Gyre. However, the presence of a well-defined circulation could not be confirmed until November 4, when Tropical Depression Eighteen formed at 12:00 UTC roughly {{convert|205|mi|km|abbr=on|round=5}} southwest of Kingston, Jamaica. The depression continued to strengthen, and became Tropical Storm Rafael six hours later. The storm tracked northwestward along the southwestern side of a ridge over the western Atlantic on November 5, and passed to the west of Jamaica. That afternoon it developed an inner wind core, and strengthened into a hurricane early on November 6. Later that day, at 21:15 UTC, Rafael made landfall just east of Playa Majana, in the Cuban province of [[Artemisa]], with winds of {{cvt|100|kn|mph km/h|order=out|round=5}}. A few hours later, the system entered the Gulf of Mexico, as a weaker Category 2 hurricane. It then proceeded to turn west-northwestward and re-intensify, becoming a major hurricane once again early on November 8 with peak winds of {{cvt|105|kn|mph km/h|order=out|round=5}} and a minimum pressure of {{convert|954|mbar|inHg|abbr=on}}. That afternoon, however, the system turned westward and began losing strength and organization, due to increasing westerly wind shear and dry air intrusion. This trend continued, and Rafael was downgraded to a tropical storm early on November 9. Rafael's remaining convection collapsed on November 10, and it degenerated into a [[remnant low]] about {{convert|230|mi|km|abbr=on|round=5}} southwest of [[Port Fourchon, Louisiana]], before opening up into a [[trough (meteorology)|trough]] on the next day.<ref name="rtcr">{{cite report|last=Blake|first=Eric|title=Tropical Cyclone Report: Hurricane Rafael|date=March 10, 2025|url=https://www.nhc.noaa.gov/data/tcr/AL182024_Rafael.pdf|publisher=National Hurricane Center|location=Miami, Florida|access-date=April 6, 2025}}</ref>

{{main|Tropical Storm Sara}}
On November 11, a large area of low-pressure merged with a tropical wave south of [[Hispaniola]] over the central Caribbean Sea. The system moved generally westward and gradually organized over the next few days. Then, early on November 14, the system developed into Tropical Depression Nineteen about {{cvt|150|mi|km|round=5|abbr=on}} east of the Honduras-Nicaragua border. Later that day, Air Force Reserve reconnaissance aircraft found maximum sustained winds of around {{cvt|35|kn|mph km/h|order=out|round=5}}, indicating that the depression strengthened into Tropical Storm Sara. The cyclone then made landfall in Honduras near Punt Patuca early on November 15, but soon re-emerged into the Caribbean and strengthened further, peaking with winds of 50 mph (85 km/h) and a minimum pressure of {{convert|997|mbar|inHg|abbr=on}} around 12:00 UTC.

On April 2, 2025, during the 47th Session of the RA IV Hurricane Committee, the [[World Meteorological Organization]] retired the names ''Beryl'', ''Helene'', and ''Milton'' from its rotating name lists due to the severity of the damage and number of deaths the three storms caused, and they will not be used again in the North Atlantic basin. They were replaced with ''Brianna'', ''Holly'',{{#tag:ref|The name Holly was used twice under previous naming conventions: [[1969 Atlantic hurricane season#Hurricane Holly|in 1969]], and [[1976 Atlantic hurricane season#Hurricane Holly|in 1976]].|group="nb"}} and ''Miguel'', respectively, which will first appear on the 2030 season list.<ref>{{Cite news|date=April 2, 2025|title=WMO Hurricane Committee retires names of Beryl, Helene, Milton and John|url=https://wmo.int/media/news/wmo-hurricane-committee-retires-names-of-beryl-helene-milton-and-john|author=World Meteorological Organization|access-date=April 2, 2025 |archive-url=https://web.archive.org/web/20250409211622/https://wmo.int/news/media-centre/wmo-hurricane-committee-retires-names-of-beryl-helene-milton-and-john |archive-date=April 9, 2025}}</ref>

== Season effects ==

This is a table of all of the storms that formed in the 2024 Atlantic hurricane season. It includes their name, duration, peak classification and intensities, areas affected, damage, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2024 USD.

The '''2024–25 South-West Indian Ocean cyclone season''' was tied as the third-busiest season in the South-West Indian Ocean since records began in 1967, and the costliest in the basin, surpassing the [[2018–19 South-West Indian Ocean cyclone season|2018–19]] season, mostly due to [[Cyclone Chido]]. It was an above-average season featuring thirteen named storms (three of them crossed from the Australian region), nine tropical cyclones, six intense tropical cyclones, and only one very intense tropical cyclone. The season began on 15 November 2024 and ended on 30 April 2025, with the exception of [[Mauritius]] and the [[Seychelles]], for which it ended on 15 May 2025. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of [[90th meridian east|90°E]] and south of the [[Equator]]. However, tropical cyclones can form year-round, with any cyclone forming between 1 July 2024 and 30 June 2025, such as 01, Ancha, and Bheki, being part of the season.

The first system formed before the official start of the season, Tropical Depression 01, but the disturbance failed to organize into a tropical storm and dissipated on 17 August. In late September, Tropical Storm Ancha formed without making landfall, and a month later, three days before the official start of the season, Tropical Storm Bheki formed, which became the first intense tropical cyclone of the season a few days later, leaving heavy rains in the [[Mascarene Islands]]. In mid-December, Tropical Storm Chido formed and rapidly intensified into a Category 4-equivalent tropical cyclone two days later, then made landfall on [[Agaléga Islands|Agaléga North Island]]. Chido then peaked as a high-end Category 4 equivalent cyclone before weakening down to a Category 3 then eventually to a Category 2 northeast of Madagascar. The cyclone then rapidly intensified back to a Category 4 equivalent cyclone and made landfall on [[Mayotte]], becoming the strongest landfalling cyclone in the island on record. Chido went on to strike Mozambique as a powerful Category 4 equivalent cyclone. Dikeledi formed on 6 January, gradually intensifying over the next four days until making landfalling in Northern Madagascar as a Category 2 equivalent cyclone on 11 January. The cyclone weakened to a tropical storm south of Mayotte before rapidly strengthening back to Category 2 intensity, making landfall near [[Nacala]] at that strength on 13 January.

In late January, two tropical cyclones formed; one of them was the moderate Tropical Storm Faida, which brought heavy rainfall to Madagascar on 5 February. After Faida dissipated, Tropical Cyclone Vince entered the basin from the Australian region on 4 February. Four days later, it became the most intense cyclone of the season and the first very intense tropical cyclone since [[Cyclone Freddy]] two years before. At 12 February, Vince had transitioned to being extratropical. At the same day, Taliah had entered the basin fluctuating between a moderate tropical storm and a strong tropical storm before becoming a post-tropical cyclone at 18 February. Six days later, Garance and Honde had formed, Garance receiving its name the day after. Garance intensified rapidly into an Intense Tropical Cyclone, making landfall at [[Réunion]] at 28 February as a Category 2. Honde brought heavy rainfall to [[Mozambique]] and then southern Madagascar as a Category 1. Jude formed as a disturbance south of the [[Chagos Islands]] on 6 March. It intensified at 8 March, receiving its name. Ivone entered the basin on 8 March and on the same day intensified to a Moderate Tropical Storm and received its name. Jude made landfall in Mozambique as a Category 1 at 10 March. Courtney from the Australian region entered the basin on 29 March, becoming an intense tropical cyclone. After nearly a month of inactivity, on 20 April Subtropical storm Kanto was named reaching a peak intensity of 75 km/h (10 minute sustained) winds with a central pressure of 993 hPa. This was the first subtropical storm named by Meteo France, which added the subtropical cyclone category starting with this cyclone season.

===Preseason/early-season activity===
The season officially started on 15 November 2024; however, the first system, Tropical Depression 01, formed on 15 August, a whole three months before the official start. In late–September, Moderate Tropical Storm Ancha formed on 30 September and dissipated five days later without making landfall. Three days before the official start of the season, Tropical Storm Bheki formed, which days later became the first intense tropical cyclone in the basin. Bheki caused heavy rainfall in parts of the [[Mascarene Islands]] such as [[Réunion]] and [[Rodrigues]]. After the dissipation of Bheki, Tropical Storm Chido formed on 9 December, and two days later became the second intense tropical cyclone of the season. Chido devastated Agaléga, Mayotte, and Mozambique, and caused hundreds of deaths and injuries.

===Peak season activity===
[[File:Garance and Honde 2025-02-28 0730Z.jpg|200px|thumb|right|Two systems active on 28 February near Madagascar: Tropical Cyclone Honde (left) and Intense Tropical Cyclone Garance (right).]]
Cyclone Dikeledi formed near [[Java]], [[Indonesia]] on 30 December 2024, and was named on 9 January. It hit [[Madagascar]] as a tropical cyclone, then [[Mozambique]], fluctuating in strength. It peaked as an intense tropical cyclone on 16 January, setting a record for its southerly location, before weakening and becoming extratropical on 17 January. In late January, Moderate Tropical Storm Elvis formed in the southern [[Mozambique Channel]] where it brought heavy rain to south-western Madagascar specifically in the [[Toliara Province]] but also the [[Morombe District]]. Soon after on 28 January [[RSMC La Réunion]] started to monitor tropical disturbance 07. It strengthened to Tropical Depression 07 the next day and remained that intensity whilst impacting [[Rodrigues]], where a class 2 cyclone warning was issued, and [[Mauritius]] where a class 1 was issued. It also effected Réunion's weather before moving away to the west-north-west towards Madagascar, where it eventually strengthened into Moderate Tropical Storm Faida on 2 February. However, in post-storm analysis Faida was downgraded to tropical depression status.

Early on 4 February, Tropical Cyclone Vince moved into the basin, from the Australian Region. Vince would continue to steadily intensify until 6 February, when Vince underwent rapid intensification, and acquired winds of 155 miles per hour, and a minimum central pressure of 924 millibars. Tropical Cyclone Taliah also moved into the basin from the Australian Region on 12 February at tropical cyclone intensity. On 24 February, two tropical cyclones formed near [[Madagascar]], Garance and Honde, one of which became an intense tropical cyclone three days later. On 24 February, two tropical cyclones formed near Madagascar, Garance and Honde. Garance rapidly intensified, reaching intense tropical cyclone status on 27 February, with peak winds of 110 miles per hour and a minimum central pressure of 951 millibars. Honde, a larger and less intense system, gradually strengthened, reaching tropical cyclone status on 28 February, with peak winds of 75 miles per hour and a minimum central pressure of 968 millibars.

===Late season activity===

Ivone and Jude formed on 8 March, in the far-eastern South-West Indian Ocean and Mozambique channel, respectively. Ivone reached its peak as a Severe Tropical Storm on 9 March. Ivone turned post-tropical on 11 March.
Jude made landfall in Mozambique as a Tropical Cyclone also on 11 March, and dissipated on the same day over Mozambique, but re-emerged as a tropical storm over the Mozambique Channel two days later. On 29 March, Severe Tropical Cyclone Courtney entered in the basin, and later this day it peaked with winds of 125 mph (205 km/h) before weakening far from land. It transitioned into an post-tropical cyclone on 31 March.

After a period of nearly a month with little activity, Meteo France began monitoring a weather system far south of Madagascar that showed potential for subtropical development, and on 20 April, it was classified as a subtropical depression; later that same evening, Madagascar's Meteorological services further upgraded it to a [[subtropical storm]], assigning it the name Kanto, which marked the first subtropical storm named by Meteo France.

The MFR upgraded Tropical Depression 06 into Tropical Storm Faida on 28 February.

According to [[Météo-France]], there was generally 30 to 50 mm of rain in the north and east of [[Réunion|Réunion Island]], with higher totals on the mountain slopes reaching 100 to 150 mm and, locally, up to 180 mm in Brûlé, south of [[Saint-Denis, Réunion|Saint-Denis]]. These quantities were not enough to compensate for the rainfall deficit of almost 80% on average on the island over the previous two months.

On 4 February, Severe Tropical Cyclone Vince entered the South-West Indian Ocean basin from the Australian Region. Vince would continue to steadily intensify until the 6 February, when Vince underwent [[rapid intensification]], and acquired 10-minute sustained winds of {{convert|130|mph|km/h|abbr=on|round=5}}, and a minimum central pressure of 930 millibars late on 6 February. The storm fluctuated in intensity until where at 06:00 UTC of 7 February it resumed strengthening.<ref name=bsh>https://www.ssd.noaa.gov/PS/TROP/DATA/ATCF/JTWC/bsh132025.dat</ref> Later that day Vince would be upgraded to a Very Intense Tropical Cyclone.

[[Météo-France]] began monitoring an area of potential development in the southern [[Mozambique Channel]] on 24 February. Unlike Garance, which organised quickly, this system was much larger and more disorganised, requiring more time to develop. Several days before its formation, the system that would become Tropical Cyclone Honde was already bringing heavy and disruptive rainfall to southern [[Mozambique]] and, particularly, [[Madagascar]]. Météo-France officially upgraded Honde to a Moderate Tropical Storm on 26 February. Subsequently, it gradually strengthened to a Severe Tropical Storm the following day, before reaching Tropical Cyclone stage on 28 February, when it made its closest approach to Madagascar.

Honde caused severe damage in Madagascar. 43,200 people were affected, mainly in the Andrefana and Menabe regions. 7,200 homes were damaged and 1,900 homes were destroyed from strong winds and flooding. Three people were killed and 69 were injured during the storm.<ref>{{Cite web |date=6 March 2025 |title=Tropical Cyclone Honde - Feb 2025 {{!}} ReliefWeb |url=https://reliefweb.int/disaster/tc-2025-000025-mdg |access-date=9 March 2025 |website=reliefweb.int |language=en}}</ref>

On 29 March, Severe Tropical Cyclone Courtney entered from the Australian region. The system intensified further to a 140 mph (220 km/h) cyclone with a minimum central pressure of 929 according to Meteo France shortly after its arrival in the basin. Later that day, it started to show signs of weakening due to cooler sea surface temperatures. The Dvorak analysis carried out by the RSMC initially gave winds at 140 mph. The best track has therefore been revised slightly downwards to peaking at 125 mph instead.  Courtney turned into a post-tropical cyclone due to nearby dry air, wind shear, and cooler water while traversing through the Indian Ocean. The remnants of Courtney then travelled between Australia and Antarctica. There were no reports of damages.

Kanto was the first subtropical system to develop in the region since Subtropical Depression Issa during the 2021–22 season. It was also the first to be designated a "subtropical storm" by Meteo France, which was introduced as a category for subtropical cyclones with maximum sustained winds above {{convert|65|km/h|mph|abbr=on}} beginning with the 2024–25 season.<ref>{{cite report|title=Regional Association I — Tropical Cyclone Operational Plan for the South-West Indian Ocean|date=2023|access-date=21 April 2025|publisher=World Meteorological Organization|url=https://wmoomm.sharepoint.com/:b:/s/wmocpdb/EYlTpV0sKLFAjl1s8ktbVBgBLNG3v60mFBTQ9TXnOcZZUw?e=GfpWcm}}</ref>

== Storm names ==
{{Main|Tropical cyclone naming}}
Within the South-West Indian Ocean, tropical depressions and subtropical depressions that are judged to have 10-minute sustained windspeeds of 65 km/h (40 mph) by the [[Regional Specialized Meteorological Center]] on [[Réunion]] island, France (RSMC La Réunion) are usually assigned a name. However, it is the Sub-Regional Tropical Cyclone Advisory Centers in Mauritius and Madagascar who name the systems. The Sub-Regional Tropical Cyclone Advisory Center (Mauritius Meteorological Services) in Mauritius names a storm if it intensifies into a moderate tropical storm between [[55th meridian east|55°E]] and [[90th meridian east|90°E]]. If instead a cyclone intensifies into a moderate tropical storm between [[30th meridian east|30°E]] and [[55th meridian east|55°E]] then the Sub-Regional Tropical Cyclone Advisory Center (Meteo Madagascar) in Madagascar assigns the appropriate name to the storm. Storm names are taken from three pre-determined lists of names, which rotate on a triennial basis, with any names that have been used automatically removed. New names this season are: Ancha, Bheki, Chido, Dikeledi, Elvis, Faida, Garance, Honde, Ivone, Jude, Kanto and Lira. They replaced Ana, Batsirai, Cliff, Dumako, Emnati, Fezile, Gombe, Halima, Issa, Jasmine and Karim during the [[2021–22 South-West Indian Ocean cyclone season|2021–22 season]], and also Letlama, which was not used, but the reason for its removal is unknown.<ref name="SWIO TCOP">{{cite report|author=RA I Tropical Cyclone Committee |publisher=World Meteorological Organization |title=Tropical Cyclone Operational Plan for the South-West Indian Ocean|year=2023|format=PDF |url=https://community.wmo.int/en/tropical-cyclone-operational-plans|archive-url=https://web.archive.org/web/20240702081536/https://www.theedkins.co.uk/storms/RAI_TCC-25_OperationalPlan_WMO-Nr1178_EN.pdf|archive-date=2 July 2024}}</ref>

If a tropical cyclone crosses 90°E into the South-West Indian basin from the [[Tropical cyclone basins#Australian region|Australian region basin]], it will retain the name assigned to it by the [[Australian Bureau of Meteorology]] (BoM). The following storms were named in this manner.<ref>{{cite report |url=http://www.bom.gov.au/cyclone/tropical-cyclone-knowledge-centre/understanding/tc-names/ |title=Tropical cyclone names |date= |publisher=[[Australian Bureau of Meteorology]] |archive-url=https://web.archive.org/web/20221226050506/http://www.bom.gov.au/cyclone/tropical-cyclone-knowledge-centre/understanding/tc-names/ |archive-date=26 December 2022 |access-date=26 December 2022}}</ref>

The '''2024–25 South-West Indian Ocean cyclone season''' was the third-busiest season in the South-West Indian Ocean since records began in 1967, and the costliest in the basin, surpassing the [[2018–19 South-West Indian Ocean cyclone season|2018–19]], mostly due to [[Cyclone Chido]]. It was an above-average season featuring thirteen named storms (three of them crossed from the Australian region), nine tropical cyclones, six intense tropical cyclones, and only one very intense tropical cyclone. The season began on 15 November 2024 and ended on 30 April 2025, with the exception of [[Mauritius]] and the [[Seychelles]], for which it ended on 15 May 2025. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of [[90th meridian east|90°E]] and south of the [[Equator]]. However, tropical cyclones can form year-round, with any cyclone forming between 1 July 2024 and 30 June 2025, such as 01, Ancha, and Bheki, being part of the season.

The first system formed before the official start of the season, Tropical Depression 01, but the disturbance failed to organize into a tropical storm and dissipated on 17 August. In late September, Tropical Storm Ancha formed without making landfall, and a month later, three days before the official start of the season, Tropical Storm Bheki formed, which became the first intense tropical cyclone of the season a few days later, leaving heavy rains in the [[Mascarene Islands]]. In mid-December, Tropical Storm Chido formed and rapidly intensified into a Category 4-equivalent tropical cyclone two days later, then made landfall on [[Agaléga Islands|Agaléga North Island]]. Chido then peaked as a high-end Category 4 equivalent cyclone before weakening down to a Category 3 then eventually to a Category 2 northeast of Madagascar. The cyclone then rapidly intensified back to a Category 4 equivalent cyclone and made landfall on [[Mayotte]], becoming the strongest landfalling cyclone in the island on record. Chido went on to strike Mozambique as a powerful Category 4 equivalent cyclone. Dikeledi formed on 6 January, gradually intensifying over the next four days until making landfalling in Northern Madagascar as a Category 2 equivalent cyclone on 11 January. The cyclone weakened to a tropical storm south of Mayotte before rapidly strengthening back to Category 2 intensity, making landfall near [[Nacala]] at that strength on 13 January.

In late January, two tropical cyclones formed; one of them was the moderate Tropical Storm Faida, which brought heavy rainfall to Madagascar on 5 February. After Faida dissipated, Tropical Cyclone Vince entered the basin from the Australian region on 4 February. Four days later, it became the most intense cyclone of the season and the first very intense tropical cyclone since [[Cyclone Freddy]] two years before. At 12 February, Vince had transitioned to being extratropical. At the same day, Taliah had entered the basin fluctuating between a moderate tropical storm and a strong tropical storm before becoming a post-tropical cyclone at 18 February. Six days later, Garance and Honde had formed, Garance receiving its name the day after. Garance intensified rapidly into an Intense Tropical Cyclone, making landfall at [[Réunion]] at 28 February as a Category 2. Honde brought heavy rainfall to [[Mozambique]] and then southern Madagascar as a Category 1. Jude formed as a disturbance south of the [[Chagos Islands]] on 6 March. It intensified at 8 March, receiving its name. Ivone entered the basin on 8 March and on the same day intensified to a Moderate Tropical Storm and received its name. Jude made landfall in Mozambique as a Category 1 at 10 March. Courtney from the Australian region entered the basin on 29 March, becoming an intense tropical cyclone. After nearly a month of inactivity, on 20 April Subtropical storm Kanto was named reaching a peak intensity of 75 km/h (10 minute sustained) winds with a central pressure of 993 hPa. This was the first subtropical storm named by Meteo France, which added the subtropical cyclone category starting with this cyclone season.

The season officially started on 15 November 2024; however, the first system, Tropical Depression 01, formed on 15 August, a whole three months before the official start. In late–September, Moderate Tropical Storm Ancha formed on 30 September and dissipated five days later without making landfall. Three days before the official start of the season, Tropical Storm Bheki formed, which days later became the first intense tropical cyclone in the basin. Bheki caused heavy rainfall in parts of the [[Mascarene Islands]] such as [[Réunion]] and [[Rodrigues]]. After the dissipation of Bheki, Tropical Storm Chido formed on 9 December, and two days later became the second intense tropical cyclone of the season. Chido devastated Agaléga, Mayotte, and Mozambique, and caused hundreds of deaths and injuries.

===Peak season activity===
[[File:Garance and Honde 2025-02-28 0730Z.jpg|200px|thumb|right|Two systems active on 28 February near Madagascar: Tropical Cyclone Honde (left) and Intense Tropical Cyclone Garance (right).]]
Cyclone Dikeledi formed near [[Java]], [[Indonesia]] on 30 December 2024, and was named on 9 January. It hit [[Madagascar]] as a tropical cyclone, then [[Mozambique]], fluctuating in strength. It peaked as an intense tropical cyclone on 16 January, setting a record for its southerly location, before weakening and becoming extratropical on 17 January. In late January, Moderate Tropical Storm Elvis formed in the southern [[Mozambique Channel]] where it brought heavy rain to south-western Madagascar specifically in the [[Toliara Province]] but also the [[Morombe District]]. Soon after on 28 January [[RSMC La Réunion]] started to monitor tropical disturbance 07. It strengthened to Tropical Depression 07 the next day and remained that intensity whilst impacting [[Rodrigues]], where a class 2 cyclone warning was issued, and [[Mauritius]] where a class 1 was issued. It also effected Réunion's weather before moving away to the west-north-west towards Madagascar, where it eventually strengthened into Moderate Tropical Storm Faida on 2 February. However, in post-storm analysis Faida was downgraded to tropical depression status.

Early on 4 February, Tropical Cyclone Vince moved into the basin, from the Australian Region. Vince would continue to steadily intensify until 6 February, when Vince underwent rapid intensification, and acquired winds of 155 miles per hour, and a minimum central pressure of 924 millibars. Tropical Cyclone Taliah also moved into the basin from the Australian Region on 12 February at tropical cyclone intensity. On 24 February, two tropical cyclones formed near [[Madagascar]], Garance and Honde, one of which became an intense tropical cyclone three days later. On 24 February, two tropical cyclones formed near Madagascar, Garance and Honde. Garance rapidly intensified, reaching intense tropical cyclone status on 27 February, with peak winds of 110 miles per hour and a minimum central pressure of 951 millibars. Honde, a larger and less intense system, gradually strengthened, reaching tropical cyclone status on 28 February, with peak winds of 75 miles per hour and a minimum central pressure of 968 millibars.

===Late season activity===

Ivone and Jude formed on 8 March, in the far-eastern South-West Indian Ocean and Mozambique channel, respectively. Ivone reached its peak as a Severe Tropical Storm on 9 March. Ivone turned post-tropical on 11 March.
Jude made landfall in Mozambique as a Tropical Cyclone also on 11 March, and dissipated on the same day over Mozambique, but re-emerged as a tropical storm over the Mozambique Channel two days later. On 29 March, Severe Tropical Cyclone Courtney entered in the basin, and later this day it peaked with winds of 125 mph (205 km/h) before weakening far from land. It transitioned into an post-tropical cyclone on 31 March.

After a period of nearly a month with little activity, Meteo France began monitoring a weather system far south of Madagascar that showed potential for subtropical development, and on 20 April, it was classified as a subtropical depression; later that same evening, Madagascar's Meteorological services further upgraded it to a [[subtropical storm]], assigning it the name Kanto, which marked the first subtropical storm named by Meteo France.

On 12 February, Tropical Cyclone Taliah crossed over from the Australian region at [[List of South-West Indian Ocean moderate tropical storms|moderate tropical storm]] intensity, having formed there on 31 January. Almost immediately, Taliah reintensified into a tropical cyclone before weakening into a moderate tropical storm the next day while moving southwest.<ref>{{cite web|url=https://www.ssd.noaa.gov/PS/TROP/DATA/ATCF/JTWC/bsh142025.dat|title=Severe Tropical Cyclone Taliah Best Track|work=Joint Typhoon Warning Center|publisher=National Oceanic and Atmospheric Administration|access-date=12 February 2025}}</ref>

Taliah then continued on its path while varying in intensity between moderate and strong tropical storm before becoming a [[post-tropical cyclone]] on 18 February near 31°S latitude over increasingly cooler waters and showing very sporadic storm activity far from the center.

[[Météo-France]] started monitoring what would become Garance on 24 February. It subsequently received the name Garance, and was upgraded to a Moderate Tropical Storm on 25 February. From 26 to 27 February, Garance rapidly intensified into an Intense Tropical Cyclone. The purple alert was issued in Reunion on 28 February, as the cyclone approached.<ref>{{Cite web|url=https://www.france24.com/en/asia-pacific/20250228-cyclone-garance-puts-mauritius-la-reunion-on-high-alert |title=La Reunion island under 'purple alert' as Cyclone Garance approaches |access-date=28 February 2025 |website=France 24|date=28 February 2025 }}</ref> On 28 February, Intense Tropical Cyclone Garance made landfall at 10:00 RET in the morning near [[Sainte-Suzanne, Réunion|Sainte-Suzanne]], in the north of [[Réunion]] at Tropical Cyclone intensity.

[[Météo-France]] began monitoring an area of potential development in the southern [[Mozambique Channel]] on 24 February. Unlike Garance, which organised quickly, this system was much larger and more disorganised, requiring more time to develop. Several days before its formation, the system that would become Tropical Cyclone Honde was already bringing heavy and disruptive rainfall to southern [[Mozambique]] and, particularly, [[Madagascar]]. Météo-France officially upgraded Honde to a Moderate Tropical Storm on 26 February. Subsequently, it gradually strengthened to a Severe Tropical Storm the following day, before reaching Tropical Cyclone stage on 28 February, when it made its closest approach to Madagascar.

Honde caused severe damage in Madagascar. 43,200 people were affected, mainly in the Andrefana and Menabe regions. 7,200 homes were damaged and 1,900 homes were destroyed from strong winds and flooding. Three people were killed and 69 were injured during the storm.<ref>{{Cite web |date=6 March 2025 |title=Tropical Cyclone Honde - Feb 2025 {{!}} ReliefWeb |url=https://reliefweb.int/disaster/tc-2025-000025-mdg |access-date=9 March 2025 |website=reliefweb.int |language=en}}</ref>

Honde weakened into a tropical storm after passing Madagascar. Before turning extratropical, Honde briefly strengthened into a severe tropical storm on 5 March in the Southern Indian Ocean.

[[Météo-France]] began monitoring a disturbance south of the [[Chagos Islands]] on 6 March. It got upgraded to a depression a day later. It was then upgraded to a Moderate Tropical Storm on 8 March, where it got the name Jude. The tropical cyclone made landfall in Cabaceira, [[Mozambique]] as a Category 1 at 10 March.

In the municipality of [[Nacala-Porto]], six fatalities were recorded.<ref>{{Cite web |title=Mozambique: Tropical storm leaves fatalities and trail of destruction in Nampula |url=https://clubofmozambique.com/news/mozambique-tropical-storm-leaves-fatalities-and-trail-of-destruction-in-nampula-277563/ |access-date=11 March 2025 |website=Mozambique |language=en-US}}</ref> Overall, the cyclone caused 16 fatalities in Mozambique,<ref name=death-Jude-Mozambique>{{Cite web |last=Presse |first=AFP-Agence France |title=Mozambique Cyclone Death Toll Rises To 16 |url=https://www.barrons.com/articles/mozambique-cyclone-death-toll-rises-to-16-0ea12132 |access-date=15 March 2025 |website=barrons |language=en-us}}</ref> 2 in Madagascar,<ref name=death-Jude-Madagascar>{{cite web |language=en |url=https://reliefweb.int/report/madagascar/southern-africa-tropical-cyclone-jude-flash-update-no-1-11-march-2025 |title=Southern Africa: Tropical Cyclone Jude Flash Update No. 1 (as of 11 March 2025) |author=[[OCHA]] |date=11 March 2025 |publisher=ReliefWeb |access-date=11 March 2025}}</ref><ref name=OCHA-3-Jude>{{cite web |language=en |url=https://reliefweb.int/report/madagascar/southern-africa-tropical-storm-jude-flash-update-no-2-18-march-2025 |title=Southern Africa: Tropical Storm Jude Flash Update No. 2 (as of 18 March 2025) |author=[[OCHA]] |date=18 March 2025 |publisher=ReliefWeb |access-date=18 March 2025}}</ref> and 3 in Malawi.<ref name=death-Malawi-Jude>{{cite news |language=en |author1=Jamal Jamal |title=Tropical Cyclone Jude kills 9 people in Mozambique, Malawi |agency=[[Anadolu Agency]] |date= 14 March 2025 |url=https://www.aa.com.tr/en/asia-pacific/tropical-cyclone-jude-kills-9-people-in-mozambique-malawi/3509203 |access-date=15 March 2025

Meteo France started monitoring this system in the extreme eastern reaches of the basin on 8 March. It was upgraded to Moderate Tropical Storm Ivone the same day.

Ivone sustained its strength for a few days, as a tropical storm before dissipating on 11 March.

}}

On 29 March, Severe Tropical Cyclone Courtney entered from the Australian region. The system intensified further to a 140 mph (220 km/h) cyclone with a minimum central pressure of 929 according to Meteo France shortly after its arrival in the basin. Later that day, it started to show signs of weakening due to cooler sea surface temperatures. The Dvorak analysis carried out by the RSMC initially gave winds at 140 mph. The best track has therefore been revised slightly downwards to peaking at 125 mph instead.  Courtney turned into a post-tropical cyclone due to nearby dry air, wind shear, and cooler water while traversing through the Indian Ocean. The remnants of Courtney then travelled between Australia and Antarctica. There were no reports of damages.

Meteo France began monitoring an extratropical system hundreds of miles south of [[Madagascar]]. On the evening of 20 April, the system transitioned into a subtropical storm, thus receiving the name Kanto by Madagascar Meteorological services.<ref>http://metservice.intnet.mu/synoptic-chart.php</ref>

Kanto was the first subtropical system to develop in the region since Subtropical Depression Issa during the 2021–22 season. It was also the first to be designated a "subtropical storm" by Meteo France, which was introduced as a category for subtropical cyclones with maximum sustained winds above {{convert|65|km/h|mph|abbr=on}} beginning with the 2024–25 season.<ref>{{cite report|title=Regional Association I — Tropical Cyclone Operational Plan for the South-West Indian Ocean|date=2023|access-date=21 April 2025|publisher=World Meteorological Organization|url=https://wmoomm.sharepoint.com/:b:/s/wmocpdb/EYlTpV0sKLFAjl1s8ktbVBgBLNG3v60mFBTQ9TXnOcZZUw?e=GfpWcm}}</ref>

== Storm names ==
{{Main|Tropical cyclone naming}}
Within the South-West Indian Ocean, tropical depressions and subtropical depressions that are judged to have 10-minute sustained windspeeds of 65 km/h (40 mph) by the [[Regional Specialized Meteorological Center]] on [[Réunion]] island, France (RSMC La Réunion) are usually assigned a name. However, it is the Sub-Regional Tropical Cyclone Advisory Centers in Mauritius and Madagascar who name the systems. The Sub-Regional Tropical Cyclone Advisory Center (Mauritius Meteorological Services) in Mauritius names a storm if it intensifies into a moderate tropical storm between [[55th meridian east|55°E]] and [[90th meridian east|90°E]]. If instead a cyclone intensifies into a moderate tropical storm between [[30th meridian east|30°E]] and [[55th meridian east|55°E]] then the Sub-Regional Tropical Cyclone Advisory Center (Meteo Madagascar) in Madagascar assigns the appropriate name to the storm. Storm names are taken from three pre-determined lists of names, which rotate on a triennial basis, with any names that have been used automatically removed. New names this season are: Ancha, Bheki, Chido, Dikeledi, Elvis, Faida, Garance, Honde, Ivone, Jude, Kanto and Lira. They replaced Ana, Batsirai, Cliff, Dumako, Emnati, Fezile, Gombe, Halima, Issa, Jasmine and Karim during the [[2021–22 South-West Indian Ocean cyclone season|2021–22 season]], and also Letlama, which was not used, but the reason for its removal is unknown.<ref name="SWIO TCOP">{{cite report|author=RA I Tropical Cyclone Committee |publisher=World Meteorological Organization |title=Tropical Cyclone Operational Plan for the South-West Indian Ocean|year=2023|format=PDF |url=https://community.wmo.int/en/tropical-cyclone-operational-plans|archive-url=https://web.archive.org/web/20240702081536/https://www.theedkins.co.uk/storms/RAI_TCC-25_OperationalPlan_WMO-Nr1178_EN.pdf|archive-date=2 July 2024}}</ref>

[[File:Major Tropical Cyclones of 2015 with text.jpg|thumb|300px|Taken by various of satellites throughout 2015, these are the 40 tropical cyclones that reached at least Category 3 on the Saffir-Simpson scale during that year, from [[Cyclone Bansi|Bansi]] in January to [[Cyclone Ula|Ula]] in December (second to last image), though it peaked in January 2016. Among them, [[Hurricane Patricia|Patricia]] (third image in the fourth row) was the most intense with a minimum central pressure of 872 hPa.]]
During 2015, [[tropical cyclone]]s formed in seven major bodies of water, commonly known as [[tropical cyclone basins]]. Tropical cyclones will be assigned names by various weather agencies if they attain [[maximum sustained winds]] of {{convert|35|knots|km/h mph|round=5}}. During the year, one hundred thirty-four systems have formed and ninety-two were named. The most intense storm of the year was [[Hurricane Patricia]], with maximum 1-minute sustained wind speeds of {{cvt|345|km/h|round=5}} and a minimum pressure of {{convert|872|hPa|inHg|sigfig=4|abbr=on|comma=off}}. The deadliest tropical cyclone was [[Cyclone Komen]], which caused 280 fatalities in Southeast India and Bangladesh, while the costliest was [[Typhoon Mujigae]], which caused an estimated $4.25 billion [[United States dollar|USD]] in damage after striking [[China]]. A record-high forty [[Saffir-Simpson scale|Category 3 tropical cyclones]] formed, including nine [[Saffir-Simpson scale|Category 5 tropical cyclones]] in the year. The [[accumulated cyclone energy]] (ACE) index for the 2015 (seven basins combined), as calculated by [[Colorado State University]] (CSU) was 1,047 units.

The most active basin in the year was the Eastern Pacific which documented 26 named systems, was its basin's most active since [[1992 Pacific hurricane season|1992]], despite only amounting to 25 named systems in the [[Pacific typhoon|Western Pacific]]. Conversely, both the [[Atlantic hurricane|North Atlantic hurricane]] and [[North Indian Ocean|North Indian Ocean cyclone]] seasons experienced a below average season numbering 11 and 4, respectively. Activity across the southern hemisphere's three basins–[[South-West Indian Ocean tropical cyclone|South-West Indian]], [[Australian region tropical cyclone|Australian]], and [[South Pacific tropical cyclone|South Pacific]]–was spread evenly, with each region recording seven named storms apiece. That hemisphere's strongest tropical cyclone was [[Cyclone Pam]], which bottomed out with a barometric pressure of 896 mbar (hPa; {{convert|896|mbar|inHg|abbr=on|sigfig=4|disp=out}}) in the South-Pacific Ocean.

Tropical cyclones are primarily monitored by a group of ten warning centers, which have been designated as a [[Regional Specialized Meteorological Centre]] (RSMC) or a [[Tropical Cyclone Warning Center]] (TCWC) by the [[World Meteorological Organization]]. These are the United States [[National Hurricane Center]] (NHC) and [[Central Pacific Hurricane Center]], the [[Japan Meteorological Agency]] (JMA), the [[Indian Meteorological Department]] (IMD), [[Météo-France]] (MFR), Indonesia's [[Meteorology, Climatology, and Geophysical Agency|Badan Meteorologi, Klimatologi, dan Geofisika]], the Australian [[Bureau of Meteorology]] (BOM), Papua New Guinea's National Weather Service, the [[Fiji Meteorological Service]] (FMS) as well as New Zealand's [[MetService]]. Other notable warning centers include the [[Philippine Atmospheric, Geophysical, and Astronomical Services Administration]] (PAGASA), the United States [[Joint Typhoon Warning Center]] (JTWC), and the [[Brazilian Navy|Brazilian Navy Hydrographic Center (BNHC)]].

{{see also|2014–16 El Niño event}}

===Background===
[[File:El Niño in November 2015.png|320px|thumb|right|Map of [[sea surface temperature]] (SST) anomalies in the Pacific Ocean in November 2015]]
By January 2015, westerly wind burst activity picked up again. The first [[Kelvin wave]] developed around March and another formed around May. In addition, another strong westerly wind burst event took place around July as a result of twin tropical cyclones straddling the equator. An even stronger event in October, and an unusually stronger event during late December 2015 into January 2016, also resulted from twin cyclones on opposite sides of the equator. In May 2015, the Australian [[Bureau of Meteorology]] respectively confirmed the arrival of weak El Niño conditions.<ref>{{cite web|url=http://www.bom.gov.au/climate/enso/archive/ensowrap_20150512.pdf|title=ENSO Wrap-Up |publisher=Australian Bureau of Meteorology|date=12 May 2015|accessdate=28 July 2015}}</ref> El Niño conditions were forecast in July to intensify into strong conditions by fall and winter of 2015.<ref>{{cite news|url=http://www.oregonlive.com/weather/index.ssf/2015/06/el_Niño_is_officially_back_and.html |title=El Niño is officially back, and looks stronger than ever |work=OregonLive.com |accessdate=28 July 2015}}</ref><ref>{{cite web|url=http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.html |archiveurl=https://web.archive.org/web/20150614040420/http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.html |archivedate=14 June 2015 |title=Climate Prediction Center: ENSO Diagnostic Discussion |accessdate=28 July 2015}}</ref> In addition to the warmer than normal waters generated by the El Niño conditions, the [[Pacific decadal oscillation|Pacific Decadal Oscillation]] was also creating persistently higher than normal sea surface temperatures in the northeastern Pacific.<ref>{{cite web |url=http://www.nnvl.noaa.gov/MediaDetail2.php?MediaID=1726&MediaTypeID=1 |title=NOAA Environmental Visualization Laboratory — July 2015 Ocean Temperatures |publisher=Nnvl.noaa.gov |date=21 July 2015 |accessdate=28 July 2015 |archive-url=https://web.archive.org/web/20150724071542/http://www.nnvl.noaa.gov/MediaDetail2.php?MediaID=1726&MediaTypeID=1 |archive-date=24 July 2015 |url-status=dead }}</ref><ref>{{cite web|title = How This Year's El Niño Compares to the Past|url = http://www.scientificamerican.com/article/how-this-year-s-el-Niño-compares-to-the-past/|accessdate = 23 July 2015|first = Andrea Thompson,Climate|last = Central| website=[[Scientific American]] }}</ref> In August, the NOAA CPC predicted that the 2015 El Niño "could be among the strongest in the historical record dating back to 1950."<ref name = TheTimes>{{cite news |last= Bremner|first= Charles|date= 15 August 2015|title= 'Godzilla' El Niño is strongest in 50 years|url= https://www.thetimes.com/travel/destinations/north-america-travel/us-travel/california/godzilla-el-nino-is-strongest-in-50-years-2nr02222dh3|newspaper= [[The Times]]|location= London, UK|url-access=subscription |access-date= 15 August 2015}}</ref> In mid November, NOAA reported that the temperature anomaly in the Niño 3.4 region for the 3-month average from August to October 2015 was the 2nd warmest on record with only 1997 warmer.<ref>{{cite web|url=https://www.climate.gov/news-features/blogs/enso/november-el-ni%C3%B1o-update-it%E2%80%99s-small-world|title=ENSO Blog: November El Niño update: It's a small world|publisher=United States National Oceanic and Atmospheric Administration|website=Climate.Gov}}</ref>

The 2014–16 El Niño event influenced tropical cyclone activity around the world, where it contributed to record breaking seasons in the Central Pacific and Eastern Pacific [[tropical cyclone basins]]. By contrast, it limited [[Atlantic hurricane]] activity, producing strong vertical wind shear, increased atmospheric stability, stronger sinking motion and drier air across the tropical Atlantic.<ref name="NOAA end of season">{{cite web|url=http://www.noaanews.noaa.gov/stories2015/120115-below-normal-atlantic-hurricane-season-ends-active-eastern-and-central-pacific-seasons-shatter-records.html|title=Below-normal Atlantic hurricane season ends; active eastern and central Pacific seasons shatter records}}</ref> The Central Pacific basin saw its most active tropical cyclone season on record with 16 tropical cyclones recorded during 2015.<ref name="NOAA end of season"/><ref>{{cite web|url=http://www.prh.noaa.gov/cphc/pages/TWS.php?dt=201601|title=Tropical Weather Summary for the Central North Pacific: January 2016|publisher=United States Central Pacific Hurricane Center}}</ref> Within the Southern Hemisphere, the El Niño pushed tropical cyclone activity in the South Pacific Ocean eastwards, with activity flourishing near [[Vanuatu]], [[Fiji]] and [[Tonga]].<ref name="Slowest">{{cite web |url=http://www.accuweather.com/en/weather-news/3-cyclones-mark-slowest-tropic/56967800 |title=3 cyclones mark slowest tropical season on record for Australia |publisher=Accuweather.com |date=30 April 2016 |accessdate=29 May 2016 |archive-date=7 October 2019 |archive-url=https://web.archive.org/web/20191007044739/https://www.accuweather.com/en/weather-news/3-cyclones-mark-slowest-tropic/56967800 |url-status=dead }}</ref><ref name="46-year record">{{cite web|author=Brian K Sullivan WeatherSullivan |url=https://www.bloomberg.com/news/articles/2016-04-20/el-nino-tames-australian-cyclones-as-46-year-old-mark-to-fall |title=El Nino Tames Australian Cyclones as 46-Year-Old Mark to Fall |publisher=Bloomberg |date=20 April 2016 |accessdate=29 May 2016}}</ref> As a result of this displacement and other factors such as a positive [[Indian Ocean Dipole]], the [[2015–16 Australian region cyclone season]] was the least active since reliable records started during the 1950s, with only three named tropical cyclones developing in the region compared to an average of eleven.<ref name="Slowest"/><ref name="46-year record"/><ref>{{cite report|publisher=Australian Bureau of Meteorology |date=May 2016 |accessdate=10 May 2016 |url=http://www.bom.gov.au/climate/updates/articles/a017.shtml |title=Dry and hot in the northern tropics |archivedate=17 June 2016 |archiveurl=https://web.archive.org/web/20160617081717/http://www.bom.gov.au/climate/updates/articles/a017.shtml |url-status=live }}</ref><ref>{{cite report|publisher=Australian Bureau of Meteorology |date=10 May 2016 |accessdate=10 May 2016 |archivedate=17 June 2016 |url=http://www.bom.gov.au/climate/tropical-note/archive/20160510.archive.shtml |title=2015–16 southern hemisphere wet-season review |archiveurl=https://web.archive.org/web/20160617084525/http://www.bom.gov.au/climate/tropical-note/archive/20160510.archive.shtml |url-status=live }}</ref>

The event also contributed to six systems forming outside of the season boundaries, within the North Atlantic, Eastern and Southern Pacific basins. These systems included Tropical Cyclone Raquel, which was considered by some to be a part of both the [[2014–15 South Pacific cyclone season|2014–15]] and [[2015–16 Australian region cyclone season|2015–16]] seasons, but was later deemed to only be a part of the 2014–15 season.<ref>{{cite report|publisher=Australian Bureau of Meteorology|date=23 October 2015|accessdate=16 November 2015|pages=1–4|url=http://www.bom.gov.au/inside/eiab/reports/ar14-15/doc/bureau-annual-report-2014-2015.pdf|title=Australian Bureau of Meteorology Annual Report 2014–15}}</ref><ref>{{cite news|title=Top 10 Most Unusual Tropical Weather Events of 2015 #10: Earliest and Latest Cyclone on Record in the South Pacific |author=Vagell, Quincy |url=https://weather.com/storms/hurricane/news/ten-odd-facts-tropics-hurricanes-2015#/2 |publisher=The Weather Channel |accessdate=30 January 2016 |archiveurl=https://web.archive.org/web/20150726022716/http://www.radionz.co.nz/international/pacific-news/277646/pacific-cyclone-in-july-a-freak-event |archivedate=26 July 2015 |url-status=live }}</ref> Tropical Depressions 01F and 02F developed in the South Pacific during July and October 2015, which affected Fiji, Vanuatu and the Solomon Islands.<ref>{{cite web|author=Young, Steve |date=31 August 2015 |title=Monthly Global Tropical Cyclone Tracks: July 2015 |url=http://www.australiasevereweather.com/cyclones/2015/trak1506.htm |url-status=live |archiveurl=https://web.archive.org/web/20151009115105/http://australiasevereweather.com/cyclones/2016/trak1507.htm |archivedate=9 October 2015 |website=Australian Severe Weather |accessdate=6 June 2016 }}</ref><ref name="15 OCT FICS">{{cite report |author=Climate Services Division |title=Fiji Climate Summary: October 2015 |accessdate=6 June 2016 |url=http://www.met.gov.fj/Summary2.pdf |archivedate=4 March 2016 |archiveurl=https://web.archive.org/web/20160304042600/http://www.met.gov.fj/Summary1.pdf |date=8 November 2015 |publisher=Fiji Meteorological Service |volume=36 |issue=10 |url-status=live }}</ref> [[2015 Pacific hurricane season#Tropical Depression Nine-C|Tropical Depression Nine-C]] subsequently formed in the Central Pacific on 31 December, whose remnants in turn contributed to the development of [[Hurricane Pali]] on 7 January.

{{Main|2015 Atlantic hurricane season}}
[[File:2015 Atlantic hurricane season summary map.png|300px|thumb|2015 Atlantic hurricane season summary map]]
The season was the last of three consecutive below-average [[Atlantic hurricane season]]s. It was a slightly below average season in which twelve tropical cyclones formed. Eleven of the twelve designated cyclones attained tropical storm status. Of the eight tropical storms, four reached at least Category 1 hurricane intensity. The 2015 season extended the period without major hurricane landfalls in the United States to ten years, with the last such system being [[Hurricane Wilma]] in [[2005 Atlantic hurricane season|2005]]. The lack of activity was primarily attributed to an atmospheric circulation that favored dry, sinking air over low latitudes to the west of 40°W and westerly wind shear enhanced by [[El Niño]].<ref name="summary">{{cite report|url=http://www.nhc.noaa.gov/data/tcr/summary_atlc_2015.pdf|title=Annual Summary: 2015 Atlantic hurricane season|author=Stacy R.

[[Hurricane Fred (2015)|Fred]] was one of the easternmost tropical storms recorded and made landfall in [[Cape Verde]] as a Category 1 hurricane, becoming the first hurricane to strike that country since [[1892 Atlantic hurricane season#Hurricane Five|1892]].<ref>{{cite web|url=https://www.wunderground.com/blog/JeffMasters/top-ten-2015-atlantic-hurricane-season-events-paris-climate-talks-ram.html|title=Top Ten 2015 Atlantic Hurricane Season Events; Paris Climate Talks Ramp Up|author1=Jeff Masters |author2=Bob Henson |date=December 1, 2015|publisher=[[Weather Underground (weather service)|Weather Underground]]|access-date=September 29, 2021}}</ref> Joaquin was the most intense storm of non-tropical origin in the satellite era and the strongest to affect the Bahamas in October since [[1866 Atlantic hurricane season#Hurricane Six|1866]].

}}</ref> The Atlantic hurricane season officially ended on November 30, 2015.
[[Tropical cyclogenesis]] began early, with Ana developing on May 8, over three weeks prior to the official beginning of the season and far ahead of the long-term climatological average of July 9. The month of June featured one tropical cyclone, Bill, which formed on June 16. Claudette, the only system in the month of July, developed on July 13. The rate of tropical cyclogenesis increased in August, though no storms developed in the first half of the month. [[Hurricane Danny (2015)|Danny]], the season's first major hurricane, formed on August 16, followed by Erika on August 24, and Fred on August 30. September, which is the climatological peak of hurricane season, featured five additional tropical cyclones – Grace, Henri, Tropical Depression Nine, Ida, and Joaquin.

The season started rather late compared to the last two years, with the first storm, Ashobaa, not developing until June 7. Ashobaa was followed by 2 depressions, before Komen formed in July. Komen produced torrential rainfall in Bangladesh. September featured no storms, before Chapala formed at the end of October. Chapala rapidly intensified over the Arabian Sea into an Extremely Severe Cyclonic Storm, becoming the strongest in the Arabian Sea since [[Cyclone Gonu|Gonu in 2007]]. Chapala also became the only hurricane force system to make landfall in Yemen, and the first since 1922 in Socotra. Chapala was followed by Megh, which reached a weaker intensity in the same general area.

Under the influence of an ongoing onset of a southwest monsoon, a low-pressure area formed on June 6. It slowly consolidated, prompting the Joint Typhoon Warning Center (JTWC) to issue a Tropical Cyclone Formation Alert (TCFA) on June 6.<ref>{{cite web|last1=Joint Typhoon Warning Center (JTWC) |title=Tropical Cyclone Formation Alert WTIO21 Issued on 06 June 2015 at 1100 UTC |url=http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/warnings/io9515web.txt |website=Joint Typhoon Warning Center (JTWC) |access-date=June 7, 2015 |url-status=dead |archive-url=https://archive.today/20240522115616/https://www.webcitation.org/6Z6QYqI2o?url=http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/warnings/io9515web.txt |archive-date=22 May 2024 }}</ref> The following day, the India Meteorological Department (IMD) issued its first advisory for the system, designating it ''ARB 01''.

The storm continued to track northwestwards for a while, before turning westwards and weakening due to moderate to high wind shear and land interaction.

A [[trough (meteorology)|trough]] over Madhya Pradesh drifted westwards into eastern [[Rajasthan]] and lead to the formation of an area of low pressure in its vicinity on July 24. Continuing on its westward track, the system became more organised and intensified into a depression on July 27, to the west of [[Jodhpur]]. A [[Western Disturbance|western disturbance]] over Pakistan and adjoining areas of [[Jammu and Kashmir (state)|Jammu and Kashmir]] kept the system from moving further north into drier portions of Rajasthan. This allowed it to intensify further into a deep depression, about {{convert|110|km|mi|abbr=on}} southeast of [[Barmer, Rajasthan|Barmer]]. However, the system accelerated in a chiefly northward track on July 29, absorbing dry air along its path.

In early October, a low-pressure area formed over the [[Arabian Sea]]. It slowly consolidated, prompting the JTWC to issue a TCFA on October 7. On October 9, the IMD started issuing its advisories for the system, designating it ARB 03. During the late hours of October 9, the JTWC stated the storm had reached gale-force winds, and commenced its advisories. On the following day, the depression intensified into a Deep depression, reaching its peak intensity with sustained wind speeds at {{convert|55|km/h|mph|abbr=on|round=5}} and a minimum central pressure estimated near {{convert|1001|mbar|inHg|abbr=on|sigfig=4}}. On the following days, the storm followed a generally northwestward track, where it encountered areas having low mid-to-upper level moisture in the atmosphere. The system struggled to maintain its intensity and weakened, prompting the JTWC to issue its final warning on ARB 03 in the morning of October 11. On next day, IMD reported that the storm had degenerated into a well-marked low-pressure area. The storm, being over water during its entire lifespan, did not directly impact any landmass. However, under the influence of the storm's rain bands, heavy Rains lashed the [[Kanyakumari district]] of [[Tamil Nadu]], India.

On 6 April, the BoM had reported that Ikola had entered the basin as a severe tropical cyclone from the Southwest Indian Ocean basin and was designated as ''19U''. Ikola rapidly weakened due to moving into a region of increasing wind shear, becoming a category 3 tropical cyclone by the evening of 7 April. Along with decreasing sea surface temperatures and further increases of wind shear caused Ikola to weaken more to a tropical low on the afternoon of 8 April. The low then proceeded to become a trough system, bringing heavy rainfall to the southwestern parts of Western Australia and severe storms to the southeast of Western Australia. Ikola soaked Central Western Australia and affected [[Perth]] from 6–12 April. Ikola was also the first cyclone to move into the Australian basin from the Southwest Indian Ocean basin since [[Cyclone Alenga (2011)|Cyclone Alenga]] in 2011.

Cyclone Lam was the strongest storm to strike Australia's Northern Territory since [[Cyclone Monica]] in 2006. It formed from the monsoon trough on 12 February in the Coral Sea. For much of its duration, the system moved westward due to a ridge to the south. The system crossed over the Cape York Peninsula and moved into the Gulf of Carpentaria, whereupon it gradually organized due to warm waters and favorable outflow. On 16 February, the Bureau of Meteorology (BoM) classified it as a Category 1 on the Australian tropical cyclone intensity scale and gave it the name Lam. The storm intensified further while drifting toward the Wessel Islands, developing an eye and strengthening to the equivalence of a minimal hurricane on 18 February. It strengthened to reach maximum sustained winds of {{convert|185|km/h|mph|abbr=on|round=5}} early on 19 February before turning to the southwest, making it a Category 4 cyclone. That day, it made landfall on Northern Territory between Milingimbi and Elcho Island at peak intensity, and it rapidly weakened over land. About six hours after Lam moved ashore, Cyclone Marcia struck Queensland as a Category 5 cyclone, marking the first time on record that two storms of Category 4 intensity struck Australia on the same day. In its formative stages, Lam produced heavy rainfall and flooding in Far North Queensland. Later, the cyclone's rainfall set daily precipitation records in Northern Territory. However, the winds caused the most damage, with gusts estimated as high as {{convert|230|km/h|mph|abbr=on|round=5}}. The highest gust was {{convert|170|km/h|mph|abbr=on|round=5}} at Cape Wessel on Rimbija Island. Lam caused considerable destruction, particularly affecting local aboriginal communities. Total damage in the Northern Territory reached at least A$82.4 million (US$64.3 million).

On 16 February, the BoM started to monitor a weak tropical disturbance in the [[Coral Sea]]. It quickly developed into a Category 1 tropical cyclone on 18 February, earning the name Marcia. It was upgraded to Category 2 the following day when it was approximately {{convert|555|km|mi}} north of [[Bundaberg]] and again upgraded to Category 3 severe tropical cyclone when approximately {{convert|290|km|mi}} north of [[Yeppoon]]. On 19 February, due to a developing, clear [[eye (cyclone)|eye]], the JTWC upgraded Marcia to a Category 2 whilst the BoM upgraded it as a Category 4. Due to [[rapid deepening|explosive intensification]], Marcia became a Category 5 according to the BoM early on 20 February. It affected [[Queensland]], and last noted on 26th of the same month as it dissipated, west-southwest of [[New Caledonia]].

On 8 March, the BoM started to monitor a weak tropical low over [[Western Australia]]. The system was later designated as ''16U'' a few days later. Due to an increase in convection, both the BoM and JTWC upgraded the system to a Category 1 tropical cyclone, naming it ''Olwyn'' on 11 March. Just before 12 March, Olwyn rapidly developed a ragged [[eye (cyclone)|eye]], as the BoM upgraded the system to a Category 3 severe tropical cyclone. Early on 13 March, Olwyn reached its peak strength of {{convert|140|km/h|mph|abbr=on}} as the JTWC classified it as a Category 2 cyclone. However, after a few hours, the JTWC downgraded it to a Category 1 cyclone as it weakened from land interaction.

Shortly after [[Cyclone Pam]] was classified on the South Pacific, the outer [[rainband]]s of Pam led to the formation of a tropical low near Australia on 9 March. Later that day, the BoM designated the system as ''17U'' and intensified into Tropical Cyclone Nathan several hours later. It slowly executed a cyclonic loop over the next few days, moving across [[Arnhem Land]].<ref>{{cite news|last=Purtill|first=James|title=Cyclone Nathan: Cyclone-ready Northern Territory town of Nhulunbuy hit harder than ever before|url=http://www.abc.net.au/news/2015-03-22/prepared-nhulunbuy-community-weathers-cyclone-nathan/6339396|access-date=23 March 2015|agency=ABC News}}</ref> {{citation needed span|After intensifying to an initial peak intensity of {{convert|165|km/h|mph|abbr=on|round=5}}, Nathan weakened while crossing the [[Cape York Peninsula]] and reintensified over the [[Gulf of Carpentaria]].

On 6 April, the BoM had reported that Ikola had entered the basin as a severe tropical cyclone from the Southwest Indian Ocean basin and was designated as ''19U''. Ikola rapidly weakened due to moving into a region of increasing wind shear, becoming a category 3 tropical cyclone by the evening of 7 April. Along with decreasing sea surface temperatures and further increases of wind shear caused Ikola to weaken more to a tropical low on the afternoon of 8 April. The low then proceeded to become a trough system, bringing heavy rainfall to the southwestern parts of Western Australia and severe storms to the southeast of Western Australia. Ikola soaked Central Western Australia and affected [[Perth]] from 6–12 April. Ikola was also the first cyclone to move into the Australian basin from the Southwest Indian Ocean basin since [[Cyclone Alenga (2011)|Cyclone Alenga]] in 2011.

On 27 April, the BoM started to monitor a tropical low over [[Western Australia]] that had formed from a monsoon trough. Later that day, the system gradually intensified as it was designated as ''21U''. The next day, 21U intensified into Tropical Cyclone Quang. Quang proceeded to intensify rapidly during 29 and 30 April, reaching a maximum intensity of a category 4 severe tropical cyclone. Quang was located 600 km northwest of the North West Cape region before turning in a southeast direction. Quang moved southeast during 1 May while rapidly weakening due to an increase of wind shear, disrupting the cyclones structure in the process. Quang was downgraded to a category 3 severe tropical cyclone in the morning of 1 May and continued to weaken during the course of the day, becoming a Category 1 before making landfall near the [[Exmouth, Western Australia|Exmouth]] coast on the night of 1 May and quickly weakened to a tropical low after it hit Exmouth. It dissipated thereafter. Quang did minimal damage to Exmouth, Western Australia.<ref>{{cite news|author=Bureau of Meteorology|access-date=25 May 2017|title=Tropical Cyclone Quang|url=http://www.bom.gov.au/cyclone/history/quang.shtml}}</ref>

Late on 30 June, Tropical Depression 17F moved into the Australian region from the [[2014–15 South Pacific cyclone season|South Pacific]] and intensified gradually into Tropical Cyclone Raquel. After drifting for the next two days, it exited the basin, moving back into the [[2015–16 South Pacific cyclone season|South Pacific]]. However, Raquel re-entered the basin early on 4 July as a weakening depression. The next day, Raquel was declared a remnant low. According to the [[Bureau of Meteorology]], it is the only known instance of a tropical cyclone during July in the region since the [[satellite]] era began (since at least 1970).<ref>{{cite news|author=Bureau of Meteorology|access-date=19 March 2016|title=Tropical Cyclone Raquel Impacts|url=http://www.bom.gov.au/announcements/sevwx/qld/qldtc20150630.shtml}}</ref> As a byproduct of becoming a tropical cyclone on the first day of the new cyclone year, it marked the earliest start to a season in the basin on record.<ref>{{cite news|author=Peter Hannam|newspaper=[[The Sydney Morning Herald]] |date=1 July 2015|access-date=2 July 2015|title=Cyclone Raquel forms as earliest big storm recorded off Australia's north-east |url=http://www.smh.com.au/environment/weather/cyclone-raquel-forms-as-earliest-big-storm-recorded-off-australias-northeast-20150701-gi23c7.html}}</ref>

===December===
[[File:Melor 2015-12-14 0215Z.jpg|thumb|[[Typhoon Melor]]]]
December was active, with 12 storms forming, however, only 3 of these storms were named, a number unusually below average. The month started with Tropical Disturbance 04F on December 1st, which impacted French Polynesia briefly before dissipating the following day. Tropical Disturbance 06F impacted Wallis and Futuna, and Tropical Depression 07F impacted the Solomon Islands, Fiji, and Tuvalu. In the South-West Indian Ocean, Cyclone Bohale stayed out to sea, not causing any threats. In the Australian Region, no cyclones were named. A few tropical lows existed, and never severely threatened land. Tropical Low 05U made landfall on Northern Territory, and extended into Queensland. In the Western Pacific, Typhoon Melor (named Typhoon Nona in the Philippines) is the strongest storm this month. Tropical Depression 29W caused minor damage to the Caroline Islands as well as the Philippines after Typhoon Melor. An unnamed tropical depression also formed and made landfall on Borneo and Malaysia. In the Eastern Pacific, Tropical Depression Nine-C became the latest forming and dissipating Tropical Cyclone in the Eastern Pacific on record, forming on December 31st, and dissipating a few hours later.

The '''2024–25 Australian region cyclone season''' was the most active season in the Australian region since [[2005–06 Australian region cyclone season|2005–06]]. This season also had the highest amount of severe tropical cyclones since 2005-06, as well as being the first non-below average season since [[2018–19 Australian region cyclone season|2018–19]]. The season recorded an average amount of tropical cyclones, an above average amount of tropical lows. The season officially started on 1 November 2024 and ended on 30 April 2025, however, a tropical cyclone could form at any time between 1 July 2024 and 30 June 2025 and would count towards the season total. During the season, tropical cyclones are officially monitored by one of the three tropical cyclone warning centres (TCWCs) for the region which are operated by the [[Australian Bureau of Meteorology]], National Weather Service of [[Papua New Guinea]] and the [[Indonesian Agency for Meteorology, Climatology and Geophysics]]. The United States [[Joint Typhoon Warning Center]] (JTWC) and other national meteorological services including [[Météo-France]] and the [[Fiji Meteorological Service]] will also monitor the basin during the season.

Ahead of the season officially starting on 1 November, the Australian [[Bureau of Meteorology]] (BoM) and New Zealand's [[National Institute of Water and Atmospheric Research]] (NIWA) both issued a tropical cyclone outlook that discussed the upcoming season.<ref name="2024–25 SO"/><ref name="NIWA">{{cite report|url=https://niwa.co.nz/sites/default/files/inline-images/Tropical-cyclone_outlook_2024-25_NIWA.pdf|publisher=New Zealand's National Institute of Water and Atmospheric Research |date=October 9, 2024 |access-date=October 29, 2024|title=2024-25 Southwest Pacific Tropical Cyclone Outlook}}</ref> These outlooks took into account a variety of factors such as a developing weak to moderate [[La Niña]] event and what had happened in previous seasons such as [[1983–84 Australian region cyclone season|1983–84]], [[1995–96 Australian region cyclone season|1995–96]], [[2005–06 Australian region cyclone season|2005–06]] and [[2017–18 Australian region cyclone season|2017–18]].<ref name="2024–25 SO"/><ref name="NIWA"/> The Southwest Pacific tropical cyclone outlook issued by New Zealand's [[National Institute of Water and Atmospheric Research]] (NIWA) in conjunction with [[MetService]], the BoM and various other Pacific meteorological services, predicted that six to ten tropical cyclones would occur over the South Pacific Ocean between 135°E and 120°W.<ref name="NIWA"/> The outlook also predicted that three to four of these tropical cyclones would intensify further and become either a Category [[List of Category 3 South Pacific severe tropical cyclones|three]], [[List of Category 4 South Pacific severe tropical cyclones|four]] or [[List of Category 5 South Pacific severe tropical cyclones|five]] severe tropical cyclone on the [[Australian tropical cyclone intensity scale]].<ref name="NIWA"/> In addition to contributing towards the Southwest Pacific tropical cyclone outlook, the BoM predicted that tropical cyclone activity within the whole region between 90°E – 160°E and each of its self-defined subregions would be near normal.<ref name="2024–25 SO"/> They also warned that the likelihood of a severe tropical cyclone was higher than average because of the warmer than average ocean temperatures that had been forecast for the region.<ref name="2024–25 SO"/>

===Early season activity===
The season officially started on 1 November, 2024. On 14 November, the [[Bureau of Meteorology]] (BoM) noted that a tropical low may form west of Sumatra.<ref name="Sumatra TL"/> A westerly wind shear enhanced the disturbance's development. Despite moderate to high wind shear displacing deep convection, the tropical low further developed and the Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert. <ref name="TCFA 04U"/> On 28 November, the BoM named Tropical Cyclone ''Robyn''. The storm officially peaked as a high-end tropical storm before increasing wind shear caused the storm to dissipate. On 4 December, Tropical Low 04U formed off the coast of [[Java]] and headed west before dissipating on 11 December. Unfortunately, the disturbance caused landslides and floods, killing eleven people and leaving seven missing.<ref name="TL 04U Deaths"/><ref name="04U Deaths"/> The rest of December had Tropical Lows 02U, 06U, 07U, and 08U. Tropical Low 07U formed southeast of the [[Cocos (Keeling) Islands|Cocos Islands]] and JTWC designated it as a tropical storm. 08U later became Category 3 [[Cyclone Dikeledi]] in the Southwest Indian Ocean.

===Peak season activity===
The first half of January had Tropical Lows 09U and 10U. The latter half had Sean, 13U, Taliah, and Vince. On 17 January, the BoM designated Tropical Low 11U, which absorbed 10U, and later named ''Sean'' on 19 January. A day later, the storm rapidly intensified to a Category 4 major cyclone on the Australian cyclone scale, possessing a distinct eye and intense winds.<ref name="C4 Sean"/> Sean dissipated a couple days later. The cyclone caused heavy rainfall and gale-force winds across portions of Western Australia. A record amount of rain fell in [[Karratha, Western Australia|Karratha]], with 274.4 mm recorded within 24 hours on 20 January.<ref name="Sean rainfall"/> Tropical Low 13U briefly tracked along the coast of Queensland and flooding killed a 63 year old woman.<ref name="13U Fatality"/> On 31 January, the BoM designated Tropical Lows 14U and 15U, which were later named ''Taliah'' and ''Vince''. After dealing with moderate wind shear, on 3 February, Taliah peaked as a Category 3 severe tropical cyclone on the Australian cyclone scale and Category 2 on the SSHWS scale.<ref name="Cyclone Taliah"/> Taliah exited the basin on 12 February. Vince was named on 2 February and also intensified to a Category 3 on the Australian cyclone scale before exiting BoM area of responsibility on 4 February. February started with Tropical Lows 16U and 19U, though both disturbances exited the basin and entered the [[Fiji Meteorological Service]] area of responsibility. Meanwhile, the BoM designated Tropical Low 18U on 7 February, which was named ''Zelia'' on 11 February. Two days later, Zelia underwent [[rapid intensification]] due to warm sea surface temperatures and relatively low wind shear. At 00:00 UTC 13 February, Zelia intensified to a Category 4 severe tropical cyclone and later to Category 5 intensity.<ref name="C4 Zelia"/> Afterward, the cyclone stalled and underwent an [[eyewall replacement cycle]] (EWRC), which ended its rapid intensification phase. Radar imagery showed an EWRC, which was later completed before landfall near [[De Grey, Western Australia|De Grey]], northeast of [[Port Hedland, Western Australia|Port Hedland]].<ref name="Zelia EWRC"/>
On 18 February, the Bureau of Meteorology designated Tropical Low 21U in the eastern side of the Indian Ocean. BOM later named the system Tropical Cyclone Bianca. On 20 February, a tropical low was spotted by the Bureau of Meteorology in the Coral Sea. The disturbance, initially designated by the agency as 22U, was noted to likely develop into a tropical cyclone over the next several days. Two days later, BOM upgraded the system to a category 1, with the name Alfred being assigned to it. On 25 February, Bianca peaked as a Category 4 severe tropical cyclone on the Australian cyclone scale and Category 3 on the SSHWS scale. Afterward, increasing wind shear and cooler sea surface temperatures caused the storm to rapidly weaken, dissipating on 27 February. Over the next couple of days, Alfred continued to gradually move to the east, and was upgraded to a Category 2 tropical cyclone in the Australian scale at 16:00 AEST on 24 February. As Alfred turned south, it intensified to Category 3 status on 26 February at 22:00 AEST. The next day, the BOM further upgraded Alfred to a Category 4 cyclone, with a small eye appearing on visible satellite imagery. Later that night, an eyewall replacement cycle (ERC) occurred, prompting Alfred to fluctuate between Categories 3 and 4 on 1 March, before further weakening down to a Category 1 the following day. The cyclone then restrengthened slightly to Category 2 status by 3 March, before being downgraded to Category 1 intensity on 8 March. Alfred made landfall at Moreton Island on 01:00 AEST March 8 as a Category 1 tropical cyclone, and was downgraded to a tropical low five hours later.<ref>{{cite web |author=|date=2025-02-25|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250225.archive.shtml|website=Bureau of Meteorology|access-date=2025-02-25}}</ref>

===Late season activity===
[[File:Cyclone Errol explosively intensifying.gif|thumb|Timelapse of Cyclone Errol explosively intensifying from Category 1 to Category 5 in less than 16 hours.]]
Tropical Low 23U formed on 4 March before exiting the basin on 8 March. The system later intensified into Tropical Storm Ivone in the South-West Indian Ocean. Tropical Cyclone 25U formed on 17 March before dissipating on 21 March. Tropical Low 27U formed on 22 March and strengthened into Tropical Cyclone Courtney three days later. Afterward, Courtney intensified to a Category 5 cyclone on the Australian cyclone scale before entering the South-West Indian Ocean on 29 March. Tropical Cyclone Dianne formed near North Australia on 28 March and made landfall near Derby on 29 March. On 8 April, Tropical Low 29U formed in the Arafura Sea. Three days later, JTWC designated ''Tropical Cyclone 29S''. Later on 15 April, 29S was designated as Errol by BoM. Shortly after the designation, the cyclone explosively intensified to a powerful Category 5 equivalent cyclone with peak winds of 260km/h and 919 hPa according to the JTWC. Tropical Low 30U formed in the Arafura Sea on 13 April. On 18 April, JTWC designated 30U as 31P. It was expected to strengthen, but wind shear soon caused it to dissipate on 23 April.

===Off-season===
On 9 May 2025, Tropical Low 33U formed near Papua New Guinea.

On 20 February, a tropical low was spotted by the [[Bureau of Meteorology]] (BOM) in the [[Coral Sea]]. The disturbance, initially designated by the agency as ''22U'', was noted to likely develop into a tropical cyclone over the next several days.<ref>{{Cite news |first=Gabrielle |last=Becerra Mellet |date=20 February 2025 |title=Cyclone likely to form off Queensland coast, BOM says |url=https://www.abc.net.au/news/2025-02-21/queensland-weather-cyclone-developing-bom/104960468 |access-date=3 March 2025 |work=ABC News}}</ref> Two days later, the [[Joint Typhoon Warning Center]] (JTWC) – which unofficially monitors all tropical cyclone basins, including the Australian region – upgraded the system to a tropical storm on the [[Saffir–Simpson scale]] (SSHWS). Initially, the BOM did not immediately follow suit and kept it as a tropical low; however, around 16:20 AEST, BOM upgraded the system to a category 1, with the name ''Alfred'' being assigned to it. Over the next couple of days, the storm continued to gradually move to the east, and was upgraded to a category 2 tropical cyclone in the Australian scale at 16:00 AEST on 24 February. As Alfred then turned south, it also continued to intensify, attaining category 3 status on 26 February at 22:00 AEST. The next day, the BOM further upgraded Alfred to a category 4 cyclone as a small eye appeared on visible satellite imagery. Later that night, an [[eyewall replacement cycle]] (ERC) occurred, prompting Alfred to fluctuate between Categories 3 and 4 on 1 March, before further weakening down to a Category 1 the following day.

Tropical Low 25U formed in the South Indian Ocean on 17 March. On 18 March, Joint Typhoon Warning Center marked system as Tropical Cyclone 26S. 25U dissipated on 21 March and its remnants were absorbed by Tropical Low 27U, which would become Tropical Cyclone Courtney.

In late April, the BoM announced that based on post event reanalysis, Tropical Low 25U briefly reached tropical cyclone (TC) intensity near the Cocos Islands on 19 March, and thus has been reassigned as an unnamed tropical cyclone.<ref>{{cite web |author=|date=2025-04-29|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250429.archive.shtml|website=Bureau of Meteorology|access-date=2025-04-30}}</ref>

Tropical Low 27U formed on 22 March, located north-west of Australia. The system intensified into a category 1 tropical cyclone on 25 March, receiving the name Courtney. Courtney strengthened for a few days, reaching its peak intensity as a Category 5 tropical cyclone on 29 March. It moved into the South-West Indian Ocean later that day, still at peak intensity.<ref>{{cite web |author=|date=2025-04-01|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250401.archive.shtml|website=Bureau of Meteorology|access-date=2025-04-04}}</ref>

Tropical Low 28U formed north of Western Australia on 25 March. On 28 March, Joint Typhoon Warning Center marked system as Tropical Cyclone 28S. Tropical Low 28U gained gale force winds in the northern quadrants of the storm. A few hours later the Bureau of Meteorology named it Dianne on 28 March. It peaked at 85km/h. Dianne made landfall just east of Cockatoo Island in the Western Australia region a short time after being named.

130 mm of rain fell in Derby, causing street flooding. However, there were no reports of significant damage.<ref>{{Cite news |date=2025-03-29 |title='You can almost surf on it': Locals welcome deluge from cyclone in WA's north |url=https://www.abc.net.au/news/2025-03-29/ex-tropical-cyclone-dianne-brings-flooding-risk-to-wa-kimberley/105112090 |access-date=2025-03-29 |work=ABC News |language=en-AU}}</ref>

Early on 16 April, it reached its peak intensity as a Category 5 equivalent tropical cyclone with 1-minute sustained winds of {{convert|140|kn|km/h mph|round=5|order=out|abbr=on|sortable=on}}, according to JTWC, while the BOM estimated 10-minute sustained winds of {{convert|100|kn|km/h mph|round=5|order=out|abbr=on|sortable=on}} which made it a Category 4 severe tropical cyclone. On 16 April, Errol began to turn south, and on 17 April, as Errol took a sharp turn southeast-east, wind shear rapidly increased to 50 knots, causing Errol to rapidly weaken. It made landfall south of Kuri Bay on 18 April as a tropical low.<ref>{{cite web |author=|date=2025-04-22|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250422.archive.shtml|website=Bureau of Meteorology|access-date=2025-04-22}}</ref> After landfall, the BoM ceased advisories on the system as it fell below warning criteria.

The '''2024–25 Australian region cyclone season''' was the most active season in the Australian region since [[2005–06 Australian region cyclone season|2005–06]]. This season also had the highest amount of severe tropical cyclones since 2005-06, as well as being the first non-below average season since [[2018–19 Australian region cyclone season|2018–19]]. The season recorded an average amount of tropical cyclones, an above average amount of tropical lows. The season officially started on 1 November 2024 and ended on 30 April 2025, however, a tropical cyclone could form at any time between 1 July 2024 and 30 June 2025 and would count towards the season total. During the season, tropical cyclones are officially monitored by one of the three tropical cyclone warning centres (TCWCs) for the region which are operated by the [[Australian Bureau of Meteorology]], National Weather Service of [[Papua New Guinea]] and the [[Indonesian Agency for Meteorology, Climatology and Geophysics]]. The United States [[Joint Typhoon Warning Center]] (JTWC) and other national meteorological services including [[Météo-France]] and the [[Fiji Meteorological Service]] will also monitor the basin during the season.

===Early season activity===
The season officially started on 1 November, 2024. On 14 November, the [[Bureau of Meteorology]] (BoM) noted that a tropical low may form west of Sumatra.<ref name="Sumatra TL"/> A westerly wind shear enhanced the disturbance's development. Despite moderate to high wind shear displacing deep convection, the tropical low further developed and the Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert. <ref name="TCFA 04U"/> On 28 November, the BoM named Tropical Cyclone ''Robyn''. The storm officially peaked as a high-end tropical storm before increasing wind shear caused the storm to dissipate. On 4 December, Tropical Low 04U formed off the coast of [[Java]] and headed west before dissipating on 11 December. Unfortunately, the disturbance caused landslides and floods, killing eleven people and leaving seven missing.<ref name="TL 04U Deaths"/><ref name="04U Deaths"/> The rest of December had Tropical Lows 02U, 06U, 07U, and 08U. Tropical Low 07U formed southeast of the [[Cocos (Keeling) Islands|Cocos Islands]] and JTWC designated it as a tropical storm. 08U later became Category 3 [[Cyclone Dikeledi]] in the Southwest Indian Ocean.

===Peak season activity===
The first half of January had Tropical Lows 09U and 10U. The latter half had Sean, 13U, Taliah, and Vince. On 17 January, the BoM designated Tropical Low 11U, which absorbed 10U, and later named ''Sean'' on 19 January. A day later, the storm rapidly intensified to a Category 4 major cyclone on the Australian cyclone scale, possessing a distinct eye and intense winds.<ref name="C4 Sean"/> Sean dissipated a couple days later. The cyclone caused heavy rainfall and gale-force winds across portions of Western Australia. A record amount of rain fell in [[Karratha, Western Australia|Karratha]], with 274.4 mm recorded within 24 hours on 20 January.<ref name="Sean rainfall"/> Tropical Low 13U briefly tracked along the coast of Queensland and flooding killed a 63 year old woman.<ref name="13U Fatality"/> On 31 January, the BoM designated Tropical Lows 14U and 15U, which were later named ''Taliah'' and ''Vince''. After dealing with moderate wind shear, on 3 February, Taliah peaked as a Category 3 severe tropical cyclone on the Australian cyclone scale and Category 2 on the SSHWS scale.<ref name="Cyclone Taliah"/> Taliah exited the basin on 12 February. Vince was named on 2 February and also intensified to a Category 3 on the Australian cyclone scale before exiting BoM area of responsibility on 4 February. February started with Tropical Lows 16U and 19U, though both disturbances exited the basin and entered the [[Fiji Meteorological Service]] area of responsibility. Meanwhile, the BoM designated Tropical Low 18U on 7 February, which was named ''Zelia'' on 11 February. Two days later, Zelia underwent [[rapid intensification]] due to warm sea surface temperatures and relatively low wind shear. At 00:00 UTC 13 February, Zelia intensified to a Category 4 severe tropical cyclone and later to Category 5 intensity.<ref name="C4 Zelia"/> Afterward, the cyclone stalled and underwent an [[eyewall replacement cycle]] (EWRC), which ended its rapid intensification phase. Radar imagery showed an EWRC, which was later completed before landfall near [[De Grey, Western Australia|De Grey]], northeast of [[Port Hedland, Western Australia|Port Hedland]].<ref name="Zelia EWRC"/>
On 18 February, the Bureau of Meteorology designated Tropical Low 21U in the eastern side of the Indian Ocean. BOM later named the system Tropical Cyclone Bianca. On 20 February, a tropical low was spotted by the Bureau of Meteorology in the Coral Sea. The disturbance, initially designated by the agency as 22U, was noted to likely develop into a tropical cyclone over the next several days. Two days later, BOM upgraded the system to a category 1, with the name Alfred being assigned to it. On 25 February, Bianca peaked as a Category 4 severe tropical cyclone on the Australian cyclone scale and Category 3 on the SSHWS scale. Afterward, increasing wind shear and cooler sea surface temperatures caused the storm to rapidly weaken, dissipating on 27 February. Over the next couple of days, Alfred continued to gradually move to the east, and was upgraded to a Category 2 tropical cyclone in the Australian scale at 16:00 AEST on 24 February. As Alfred turned south, it intensified to Category 3 status on 26 February at 22:00 AEST. The next day, the BOM further upgraded Alfred to a Category 4 cyclone, with a small eye appearing on visible satellite imagery. Later that night, an eyewall replacement cycle (ERC) occurred, prompting Alfred to fluctuate between Categories 3 and 4 on 1 March, before further weakening down to a Category 1 the following day. The cyclone then restrengthened slightly to Category 2 status by 3 March, before being downgraded to Category 1 intensity on 8 March. Alfred made landfall at Moreton Island on 01:00 AEST March 8 as a Category 1 tropical cyclone, and was downgraded to a tropical low five hours later.<ref>{{cite web |author=|date=2025-02-25|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250225.archive.shtml|website=Bureau of Meteorology|access-date=2025-02-25}}</ref>

===Late season activity===
[[File:Cyclone Errol explosively intensifying.gif|thumb|Timelapse of Cyclone Errol explosively intensifying from Category 1 to Category 5 in less than 16 hours.]]
Tropical Low 23U formed on 4 March before exiting the basin on 8 March. The system later intensified into Tropical Storm Ivone in the South-West Indian Ocean. Tropical Cyclone 25U formed on 17 March before dissipating on 21 March. Tropical Low 27U formed on 22 March and strengthened into Tropical Cyclone Courtney three days later. Afterward, Courtney intensified to a Category 5 cyclone on the Australian cyclone scale before entering the South-West Indian Ocean on 29 March. Tropical Cyclone Dianne formed near North Australia on 28 March and made landfall near Derby on 29 March. On 8 April, Tropical Low 29U formed in the Arafura Sea. Three days later, JTWC designated ''Tropical Cyclone 29S''. Later on 15 April, 29S was designated as Errol by BoM. Shortly after the designation, the cyclone explosively intensified to a powerful Category 5 equivalent cyclone with peak winds of 260km/h and 919 hPa according to the JTWC. Tropical Low 30U formed in the Arafura Sea on 13 April. On 18 April, JTWC designated 30U as 31P. It was expected to strengthen, but wind shear soon caused it to dissipate on 23 April.

===Off-season===
On 9 May 2025, Tropical Low 33U formed near Papua New Guinea.

Tropical low 11U formed on 17 January, before moving westward, and absorbing TL 10U. On 19 January, it was identified by the Bureau of Meteorology to have reached Tropical Cyclone status, and was named Sean. The following day, Sean rapidly intensified, becoming a Category 3 Severe Tropical Cyclone on the Australian scale by 8am on January 20, and a Category 2 tropical cyclone on the Saffir-Simpson scale later the same day.

On 20 February, a tropical low was spotted by the [[Bureau of Meteorology]] (BOM) in the [[Coral Sea]]. The disturbance, initially designated by the agency as ''22U'', was noted to likely develop into a tropical cyclone over the next several days.<ref>{{Cite news |first=Gabrielle |last=Becerra Mellet |date=20 February 2025 |title=Cyclone likely to form off Queensland coast, BOM says |url=https://www.abc.net.au/news/2025-02-21/queensland-weather-cyclone-developing-bom/104960468 |access-date=3 March 2025 |work=ABC News}}</ref> Two days later, the [[Joint Typhoon Warning Center]] (JTWC) – which unofficially monitors all tropical cyclone basins, including the Australian region – upgraded the system to a tropical storm on the [[Saffir–Simpson scale]] (SSHWS). Initially, the BOM did not immediately follow suit and kept it as a tropical low; however, around 16:20 AEST, BOM upgraded the system to a category 1, with the name ''Alfred'' being assigned to it. Over the next couple of days, the storm continued to gradually move to the east, and was upgraded to a category 2 tropical cyclone in the Australian scale at 16:00 AEST on 24 February. As Alfred then turned south, it also continued to intensify, attaining category 3 status on 26 February at 22:00 AEST. The next day, the BOM further upgraded Alfred to a category 4 cyclone as a small eye appeared on visible satellite imagery. Later that night, an [[eyewall replacement cycle]] (ERC) occurred, prompting Alfred to fluctuate between Categories 3 and 4 on 1 March, before further weakening down to a Category 1 the following day. The cyclone then restrengthened slightly to category 2 status by 3 March, before being downgraded to a Category 1 on 8 March.<ref name=":0">{{Cite news |date=2025-03-08 |title=Flooding risk for Queensland, northern NSW despite Alfred downgrade |url=https://www.abc.net.au/news/2025-03-08/threat-of-flooding-queensland-northern-nsw-risk-cyclone-alfred/105027148 |access-date=2025-03-08 |work=ABC News |language=en-AU}}</ref>

The '''2024–25 Australian region cyclone season''' was the most active season in the Australian region since [[2005–06 Australian region cyclone season|2005–06]]. This season also had the highest amount of severe tropical cyclones since 2005-06, as well as being the first non-below average season since [[2018–19 Australian region cyclone season|2018–19]]. The season recorded an average amount of tropical cyclones, an above average amount of tropical lows. The season officially started on 1 November 2024 and ended on 30 April 2025, however, a tropical cyclone could form at any time between 1 July 2024 and 30 June 2025 and would count towards the season total. During the season, tropical cyclones are officially monitored by one of the three tropical cyclone warning centres (TCWCs) for the region which are operated by the [[Australian Bureau of Meteorology]], National Weather Service of [[Papua New Guinea]] and the [[Indonesian Agency for Meteorology, Climatology and Geophysics]]. The United States [[Joint Typhoon Warning Center]] (JTWC) and other national meteorological services including [[Météo-France]] and the [[Fiji Meteorological Service]] will also monitor the basin during the season.

Ahead of the season officially starting on 1 November, the Australian [[Bureau of Meteorology]] (BoM) and New Zealand's [[National Institute of Water and Atmospheric Research]] (NIWA) both issued a tropical cyclone outlook that discussed the upcoming season.<ref name="2024–25 SO"/><ref name="NIWA">{{cite report|url=https://niwa.co.nz/sites/default/files/inline-images/Tropical-cyclone_outlook_2024-25_NIWA.pdf|publisher=New Zealand's National Institute of Water and Atmospheric Research |date=October 9, 2024 |access-date=October 29, 2024|title=2024-25 Southwest Pacific Tropical Cyclone Outlook}}</ref> These outlooks took into account a variety of factors such as a developing weak to moderate [[La Niña]] event and what had happened in previous seasons such as [[1983–84 Australian region cyclone season|1983–84]], [[1995–96 Australian region cyclone season|1995–96]], [[2005–06 Australian region cyclone season|2005–06]] and [[2017–18 Australian region cyclone season|2017–18]].<ref name="2024–25 SO"/><ref name="NIWA"/> The Southwest Pacific tropical cyclone outlook issued by New Zealand's [[National Institute of Water and Atmospheric Research]] (NIWA) in conjunction with [[MetService]], the BoM and various other Pacific meteorological services, predicted that six to ten tropical cyclones would occur over the South Pacific Ocean between 135°E and 120°W.<ref name="NIWA"/> The outlook also predicted that three to four of these tropical cyclones would intensify further and become either a Category [[List of Category 3 South Pacific severe tropical cyclones|three]], [[List of Category 4 South Pacific severe tropical cyclones|four]] or [[List of Category 5 South Pacific severe tropical cyclones|five]] severe tropical cyclone on the [[Australian tropical cyclone intensity scale]].<ref name="NIWA"/> In addition to contributing towards the Southwest Pacific tropical cyclone outlook, the BoM predicted that tropical cyclone activity within the whole region between 90°E – 160°E and each of its self-defined subregions would be near normal.<ref name="2024–25 SO"/> They also warned that the likelihood of a severe tropical cyclone was higher than average because of the warmer than average ocean temperatures that had been forecast for the region.<ref name="2024–25 SO"/>

===Early season activity===
The season officially started on 1 November, 2024. On 14 November, the [[Bureau of Meteorology]] (BoM) noted that a tropical low may form west of Sumatra.<ref name="Sumatra TL"/> A westerly wind shear enhanced the disturbance's development. Despite moderate to high wind shear displacing deep convection, the tropical low further developed and the Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert. <ref name="TCFA 04U"/> On 28 November, the BoM named Tropical Cyclone ''Robyn''. The storm officially peaked as a high-end tropical storm before increasing wind shear caused the storm to dissipate. On 4 December, Tropical Low 04U formed off the coast of [[Java]] and headed west before dissipating on 11 December. Unfortunately, the disturbance caused landslides and floods, killing eleven people and leaving seven missing.<ref name="TL 04U Deaths"/><ref name="04U Deaths"/> The rest of December had Tropical Lows 02U, 06U, 07U, and 08U. Tropical Low 07U formed southeast of the [[Cocos (Keeling) Islands|Cocos Islands]] and JTWC designated it as a tropical storm. 08U later became Category 3 [[Cyclone Dikeledi]] in the Southwest Indian Ocean.

===Peak season activity===
The first half of January had Tropical Lows 09U and 10U. The latter half had Sean, 13U, Taliah, and Vince. On 17 January, the BoM designated Tropical Low 11U, which absorbed 10U, and later named ''Sean'' on 19 January. A day later, the storm rapidly intensified to a Category 4 major cyclone on the Australian cyclone scale, possessing a distinct eye and intense winds.<ref name="C4 Sean"/> Sean dissipated a couple days later.

Vince was named on 2 February and also intensified to a Category 3 on the Australian cyclone scale before exiting BoM area of responsibility on 4 February. February started with Tropical Lows 16U and 19U, though both disturbances exited the basin and entered the [[Fiji Meteorological Service]] area of responsibility. Meanwhile, the BoM designated Tropical Low 18U on 7 February, which was named ''Zelia'' on 11 February. Two days later, Zelia underwent [[rapid intensification]] due to warm sea surface temperatures and relatively low wind shear. At 00:00 UTC 13 February, Zelia intensified to a Category 4 severe tropical cyclone and later to Category 5 intensity.<ref name="C4 Zelia"/> Afterward, the cyclone stalled and underwent an [[eyewall replacement cycle]] (EWRC), which ended its rapid intensification phase.

On 18 February, the Bureau of Meteorology designated Tropical Low 21U in the eastern side of the Indian Ocean. BOM later named the system Tropical Cyclone Bianca. On 20 February, a tropical low was spotted by the Bureau of Meteorology in the Coral Sea. The disturbance, initially designated by the agency as 22U, was noted to likely develop into a tropical cyclone over the next several days. Two days later, BOM upgraded the system to a category 1, with the name Alfred being assigned to it. On 25 February, Bianca peaked as a Category 4 severe tropical cyclone on the Australian cyclone scale and Category 3 on the SSHWS scale. Afterward, increasing wind shear and cooler sea surface temperatures caused the storm to rapidly weaken, dissipating on 27 February. Over the next couple of days, Alfred continued to gradually move to the east, and was upgraded to a Category 2 tropical cyclone in the Australian scale at 16:00 AEST on 24 February. As Alfred turned south, it intensified to Category 3 status on 26 February at 22:00 AEST. The next day, the BOM further upgraded Alfred to a Category 4 cyclone, with a small eye appearing on visible satellite imagery. Later that night, an eyewall replacement cycle (ERC) occurred, prompting Alfred to fluctuate between Categories 3 and 4 on 1 March, before further weakening down to a Category 1 the following day. The cyclone then restrengthened slightly to Category 2 status by 3 March, before being downgraded to Category 1 intensity on 8 March. Alfred made landfall at Moreton Island on 01:00 AEST March 8 as a Category 1 tropical cyclone, and was downgraded to a tropical low five hours later.<ref>{{cite web |author=|date=2025-02-25|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250225.archive.shtml|website=Bureau of Meteorology|access-date=2025-02-25}}</ref>

Tropical Low 23U formed on 4 March before exiting the basin on 8 March. The system later intensified into Tropical Storm Ivone in the South-West Indian Ocean. Tropical Cyclone 25U formed on 17 March before dissipating on 21 March. Tropical Low 27U formed on 22 March and strengthened into Tropical Cyclone Courtney three days later. Afterward, Courtney intensified to a Category 5 cyclone on the Australian cyclone scale before entering the South-West Indian Ocean on 29 March. Tropical Cyclone Dianne formed near North Australia on 28 March and made landfall near Derby on 29 March. On 8 April, Tropical Low 29U formed in the Arafura Sea. Three days later, JTWC designated ''Tropical Cyclone 29S''. Later on 15 April, 29S was designated as Errol by BoM. Shortly after the designation, the cyclone explosively intensified to a powerful Category 5 equivalent cyclone with peak winds of 260km/h and 919 hPa according to the JTWC. Tropical Low 30U formed in the Arafura Sea on 13 April. On 18 April, JTWC designated 30U as 31P. It was expected to strengthen, but wind shear soon caused it to dissipate on 23 April.

===Off-season===
On 9 May 2025, Tropical Low 33U formed near Papua New Guinea.

Errol formed on 9 April as Tropical Low 29U,<ref>{{cite web |author=|date=2025-04-08|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250408.archive.shtml|website=Bureau of Meteorology|access-date=2025-04-08}}</ref> and fluctuated from a Tropical Low to Category 1 from 12 April to 14 April. Starting late on 15 April, Errol begun a period of explosive deepening; 1-minute sustained winds increased from 100 km/h (65 mph) to {{cvt|260|km/h|mph|round=5|abbr=on}} in 24 hours and {{cvt|120|km/h|mph|round=5|abbr=on}} to 220 km/h (140 mph) in 12 hours, and the JTWC described it as 'explosive and extreme rapid intensification'. Early on 16 April, it reached its peak intensity as a Category 5 equivalent tropical cyclone with 1-minute sustained winds of {{convert|140|kn|km/h mph|round=5|order=out|abbr=on|sortable=on}}, according to JTWC, while the BOM estimated 10-minute sustained winds of {{convert|100|kn|km/h mph|round=5|order=out|abbr=on|sortable=on}} which made it a Category 4 severe tropical cyclone. On 16 April, Errol began to turn south, and on 17 April, as Errol took a sharp turn southeast-east, wind shear rapidly increased to 50 knots, causing Errol to rapidly weaken. It made landfall south of Kuri Bay on 18 April as a tropical low.<ref>{{cite web |author=|date=2025-04-22|title=Tropical Climate Update|url=http://www.bom.gov.au/climate/tropical-note/archive/20250422.archive.shtml|website=Bureau of Meteorology|access-date=2025-04-22}}</ref> After landfall, the BoM ceased advisories on the system as it fell below warning criteria.

Errol was a small tropical cyclone that brought heavy rain to the Northern Kimberley coast including Derby and Kalumburu on 18 and 19 April.<ref>{{Cite news |date=2025-04-18 |title=Ex-cyclone Errol 'a dodged bullet' as it crosses Kimberley as tropical low |url=https://www.abc.net.au/news/2025-04-19/ex-cyclone-errol-kimberley-tropical-low-impact-severe-weather/105192150 |access-date=2025-04-19 |work=ABC News |language=en-AU}}</ref> Kalumburu received 160.8 mm of rainfall in the 24 hours to 9 am on 19 April. Errol is the latest tropical cyclone to form or move into the Australian region since [[2021–22 Australian region cyclone season#Tropical Cyclone Karim|Karim]] which formed on 7th May 2022.

The '''2025 Pacific hurricane season''' is the next season of the annual [[Pacific hurricane season]] for the [[Northern Hemisphere]]. The season officially begins on May 15, 2025, and ends on November 30, 2025. For the Central Pacific ([[140th meridian west|140ºW]] to [[180th meridian|180º]]), the season begins on June 1, 2025, and ends on November 30, 2025. Those dates, adopted by convention, describe the period in which most subtropical or [[tropical cyclogenesis]] occurs in the [[Pacific Ocean]]. The [[National Hurricane Center]] (NHC) will begin issuing routine Tropical Weather Outlooks for east of 140ºW on May 15, 2025, and the [[Central Pacific Hurricane Center]] will begin issuing routine Tropical Weather Outlooks for west of 140ºW and east of 180º on June 1, 2025, both on the same date as the seasons starting dates.

In advance of each [[Pacific hurricane]] season, [[Tropical cyclone seasonal forecasting|forecasts of hurricane activity]] are issued by forecasters from the United States [[National Oceanic and Atmospheric Administration]] (NOAA)'s [[Climate Prediction Center]], and [[Mexico]]'s [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN). The forecasts include weekly and monthly changes in significant factors that help determine the amount of tropical storms, hurricanes, and major hurricanes within a particular season.<ref name="Background"/>

According to NOAA, the average Pacific hurricane season between 1991 and 2020 contained about 15 named storms, 8 hurricanes and 4 major hurricanes (Category 3 and higher), as well as an [[Accumulated Cyclone Energy|accumulated cyclone energy]] (ACE) index of 80–115 units. Broadly speaking, ACE is the measure of the power of a tropical or [[subtropical cyclone]] multiplied by the length of time it existed. ACE is only calculated for full advisories on specific tropical or subtropical cyclones reaching wind speeds of 39 mph (63 km/h) or higher. NOAA typically describes a season as above-average, average, or below-average depending on the cumulative ACE index, but the number of tropical storms, hurricanes or major hurricanes can also be considered.<ref name="Background"/>

On May 7, 2025, the [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN) issued its first outlook for the Pacific hurricane season, forecasting an above average season with 16–20 named storms, 8–11 hurricanes, and 4–6 major hurricanes.<ref name="SMN"/>

For storms that form in the North Pacific from 140°W to the [[International Date Line]], the names come from a series of four rotating lists. Names are used one after the other without regard to year, and when the bottom of one list is reached, the next named storm receives the name at the top of the next list.<ref name="ENP CNP"/> Any named storms that form within the area in 2025 will be listed below. Named storms in the table above that cross into the area during the season are noted (*).

==Season effects==
The following is a table which will include all of the storms that form in the 2025 Pacific hurricane season. It will include their duration, names, intensities, areas affected, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2025 USD.

The '''2025 Pacific hurricane season''' is the next season of the annual [[Pacific hurricane season]] for the [[Northern Hemisphere]]. The season officially begins on May 15, 2025, and ends on November 30, 2025. For the Central Pacific ([[140th meridian west|140ºW]] to [[180th meridian|180º]]), the season begins on June 1, 2025, and ends on November 30, 2025. Those dates, adopted by convention, describe the period in which most subtropical or [[tropical cyclogenesis]] occurs in the [[Pacific Ocean]]. The [[National Hurricane Center]] (NHC) will begin issuing routine Tropical Weather Outlooks for east of 140ºW on May 15, 2025, and the [[Central Pacific Hurricane Center]] will begin issuing routine Tropical Weather Outlooks for west of 140ºW and east of 180º on June 1, 2025, both on the same date as the seasons starting dates.

The '''2025 Atlantic hurricane season''' is the next [[Atlantic hurricane season]] in the [[Northern Hemisphere]]. The season officially begins on June 1, 2025, and will end on November 30, 2025. These dates, adopted by convention, historically describe the period in each year when most subtropical or [[tropical cyclogenesis]] occurs in the [[Atlantic Ocean]] (over 97%). The [[National Hurricane Center]] (NHC) will begin issuing regular Tropical Weather Outlooks on May 15, 2025, about two weeks prior to the start of the season.

In advance of, and during, each hurricane season, several [[Tropical cyclone seasonal forecasting|forecasts of hurricane activity]] are issued by national meteorological services, scientific agencies, and noted hurricane experts. These include forecasters from the United States [[National Oceanic and Atmospheric Administration]] (NOAA)'s [[Climate Prediction Center]], Tropical Storm Risk (TSR), the United Kingdom's [[Met Office]], and [[Colorado State University]] (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the amount of tropical storms, hurricanes, and major hurricanes within a particular season.

According to NOAA and CSU, the average hurricane season between 1991 and 2020 contained about 14 named storms, 7 hurricanes and 3 major hurricanes (Category 3 and higher), as well as an [[Accumulated Cyclone Energy|accumulated cyclone energy]] (ACE) index of 72–111 units. Broadly speaking, ACE is the measure of the power of a tropical or [[subtropical cyclone]] multiplied by the length of time it existed. ACE is only calculated for full advisories on specific tropical or subtropical cyclones reaching wind speeds of 39 mph (63 km/h) or higher. NOAA typically describes a season as above-average, average, or below-average depending on the cumulative ACE index, but the number of tropical storms, hurricanes or major hurricanes can also be considered.

=== Pre-season forecasts ===
On December 10, 2024, Tropical Storm Risk (TSR) released its extended range forecast for the 2025 season, predicting an average season with fifteen [[Tropical cyclone naming|named storms]], seven hurricanes, and three major hurricanes, but noted that the forecast had higher than normal uncertainty due to environmental factors.<ref name="Dec21TSR" />

On April 3, 2025, Colorado State University (CSU) released its forecast, which predicts an above-average hurricane season with seventeen named storms, nine hurricanes, and four major hurricanes, with an ACE index of 155, citing extremely warm Atlantic sea surface temperatures and a weakening [[La Niña]] transitioning to a neutral phase by summer.<ref name="Apr3CSU" /> Four days later, TSR issued an updated forecast, again calling for a near-average season reducing the number of tropical storms to fourteen.<ref name="Apr7TSR" /> April 9, the [[University of Arizona]] (UA) posted their forecast calling for a fairly normal season featuring fifteen named storms, seven hurricanes, three major hurricanes, and an ACE index of 110 units.<ref name="Apr9UA"/> On April 15, [[North Carolina State University]] (NCSU) predicted a season with 12–15 tropical storms, 6–8 hurricanes, and 2–3 major hurricanes.<ref name=":0" /> On April 17, [[The Weather Company]] (TWC) released their outlook anticipating an well above average season with nineteen named systems, nine hurricanes and four major hurricanes.<ref name=":1" /> On April 23, the [[University of Pennsylvania]] (UPenn) issued their forecast of 10–18 named storms with a best guess of 14 storms.<ref name="UPenn"/> On May 7, the [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN) issued their forecast of 13–17 tropical storms, 6–8 hurricanes, and 3–4 major hurricanes.<ref name="SMN"/>

The '''2025 Atlantic hurricane season''' is the next [[Atlantic hurricane season]] in the [[Northern Hemisphere]]. The season officially begins on June 1, 2025, and will end on November 30, 2025. These dates, adopted by convention, historically describe the period in each year when most subtropical or [[tropical cyclogenesis]] occurs in the [[Atlantic Ocean]] (over 97%). The [[National Hurricane Center]] (NHC) will begin issuing regular Tropical Weather Outlooks on May 15, 2025, about two weeks prior to the start of the season.

In advance of, and during, each hurricane season, several [[Tropical cyclone seasonal forecasting|forecasts of hurricane activity]] are issued by national meteorological services, scientific agencies, and noted hurricane experts. These include forecasters from the United States [[National Oceanic and Atmospheric Administration]] (NOAA)'s [[Climate Prediction Center]], Tropical Storm Risk (TSR), the United Kingdom's [[Met Office]], and [[Colorado State University]] (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the amount of tropical storms, hurricanes, and major hurricanes within a particular season.

According to NOAA and CSU, the average hurricane season between 1991 and 2020 contained about 14 named storms, 7 hurricanes and 3 major hurricanes (Category 3 and higher), as well as an [[Accumulated Cyclone Energy|accumulated cyclone energy]] (ACE) index of 72–111 units. Broadly speaking, ACE is the measure of the power of a tropical or [[subtropical cyclone]] multiplied by the length of time it existed. ACE is only calculated for full advisories on specific tropical or subtropical cyclones reaching wind speeds of 39 mph (63 km/h) or higher. NOAA typically describes a season as above-average, average, or below-average depending on the cumulative ACE index, but the number of tropical storms, hurricanes or major hurricanes can also be considered.

=== Pre-season forecasts ===
On December 10, 2024, Tropical Storm Risk (TSR) released its extended range forecast for the 2025 season, predicting an average season with fifteen [[Tropical cyclone naming|named storms]], seven hurricanes, and three major hurricanes, but noted that the forecast had higher than normal uncertainty due to environmental factors.<ref name="Dec21TSR" />

On April 3, 2025, Colorado State University (CSU) released its forecast, which predicts an above-average hurricane season with seventeen named storms, nine hurricanes, and four major hurricanes, with an ACE index of 155, citing extremely warm Atlantic sea surface temperatures and a weakening [[La Niña]] transitioning to a neutral phase by summer.<ref name="Apr3CSU" /> Four days later, TSR issued an updated forecast, again calling for a near-average season reducing the number of tropical storms to fourteen.<ref name="Apr7TSR" /> April 9, the [[University of Arizona]] (UA) posted their forecast calling for a fairly normal season featuring fifteen named storms, seven hurricanes, three major hurricanes, and an ACE index of 110 units.<ref name="Apr9UA"/> On April 15, [[North Carolina State University]] (NCSU) predicted a season with 12–15 tropical storms, 6–8 hurricanes, and 2–3 major hurricanes.<ref name=":0" /> On April 17, [[The Weather Company]] (TWC) released their outlook anticipating an well above average season with nineteen named systems, nine hurricanes and four major hurricanes.<ref name=":1" /> On April 23, the [[University of Pennsylvania]] (UPenn) issued their forecast of 10–18 named storms with a best guess of 14 storms.<ref name=":2" /> large-scale warming.<ref name="UPenn"/> On May 7, the [[Servicio Meteorológico Nacional (Mexico)|Servicio Meteorológico Nacional]] (SMN) issued their forecast of 13–17 tropical storms, 6–8 hurricanes, and 3–4 major hurricanes.<ref name="SMN"/>

The '''2025 Atlantic hurricane season''' is the next [[Atlantic hurricane season]] in the [[Northern Hemisphere]]. The season officially begins on June 1, 2025, and will end on November 30, 2025. These dates, adopted by convention, historically describe the period in each year when most subtropical or [[tropical cyclogenesis]] occurs in the [[Atlantic Ocean]] (over 97%). The [[National Hurricane Center]] (NHC) will begin issuing regular Tropical Weather Outlooks on May 15, 2025, about two weeks prior to the start of the season.

Among them, Vince (third image in the first row) is the most intense with a minimum central pressure of 923 hPa.]]
In 2025, tropical cyclones will form in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones will be named by various weather agencies when they attain [[maximum sustained winds]] of {{convert|35|knots|km/h mph|round=5}}. The strongest system this year so far is [[Cyclone Vince (2025)|Cyclone Vince]] which attained a minimum barometric pressure of 923 hPa (27.26 inHg), [[Cyclone Jude]] is the deadliest system this year so far, causing at least 21 deaths in south-east Africa. [[Cyclone Garance]] is the costliest system this year so far at $940 million in damage. The [[accumulated cyclone energy]] (ACE) index for the year (seven basins combined) so far, as calculated by Colorado State University (CSU), is 213.1 units overall.<ref>https://tropical.atmos.colostate.edu/Realtime/</ref>

Tropical cyclones are primarily monitored by ten warning centers around the world, which are designated as a [[Regional Specialized Meteorological Center]] (RSMC) or a [[Tropical Cyclone Warning Center]] (TCWC) by the [[World Meteorological Organization]] (WMO). These centers are: [[National Hurricane Center]] (NHC), [[Central Pacific Hurricane Center]] (CPHC), [[Japan Meteorological Agency]] (JMA), [[Indian Meteorological Department]] (IMD), [[Météo-France]] (MFR), Indonesia's [[Meteorology, Climatology, and Geophysical Agency]] (BMKG), Australian [[Bureau of Meteorology]] (BoM), Papua New Guinea's National Weather Service (PNGNWS), [[Fiji Meteorological Service]] (FMS), and New Zealand's [[MetService]]. Unofficial, but still notable, warning centers include the [[Philippine Atmospheric, Geophysical and Astronomical Services Administration]] (PAGASA; albeit official within the Philippines), the United States's [[Joint Typhoon Warning Center]] (JTWC), and the [[Brazilian Navy Hydrographic Center]].

In January, the [[Intertropical Convergence Zone]] (ITCZ), which allows for the formation of [[tropical wave]]s, is located in the [[Southern Hemisphere]], remaining there until May.<ref name="ITCZ">{{cite book|last=Longshore|first=David|title=Encyclopedia of Hurricanes, Typhoons, and Cyclones, New Edition|url=https://books.google.com/books?id=8kXwskQHBLoC&pg=PA115|year=2009|publisher=Infobase Publishing|isbn=978-1-4381-1879-6|page=333}}</ref> This limits [[Northern Hemisphere]] cyclone formation to comparatively rare non-tropical sources.<ref name=nontrop>{{cite web|url=http://ams.allenpress.com/perlserv/?request=get-abstract&doi=10.1175/1520-0493(1979)107%3C0812:NCSANE%3E2.0.CO;2|title=Northeasterly Cold Surges and Near-Equatorial Disturbances over the Winter MONEX Area during December 1974.

In the [[Southern Hemisphere]] basins, January, at the height of the [[austral summer]], is the most active month by cumulative number of storms since records began. Of the four Northern Hemisphere basins, none is very active in January, as the month is during the winter, but the most active basin is the Western Pacific, which occasionally sees weak tropical storms form during the month.<ref name="BOM database" /> January was unusually active, with twelve systems forming and seven storms getting named.

The month started off in the South-West Indian Ocean with [[Cyclone Dikeledi]], which intensified into a major cyclone before it made two landfalls at [[Antsiranana|Antsiranana, Madagascar]] and [[Nampula Province|Nampula Province, Mozambique]], [[Cyclone Elvis]] and [[Cyclone Faida]] also formed but was downgraded into a depression by MFR in post-storm analysis. Meanwhile, short-lived [[Cyclone Pita (2025)|Cyclone Pita]] formed on January 6, affecting some islands in the South Pacific basin. Weeks later, in the Australian basin, [[Cyclone Sean (2025)|Cyclone Sean]] developed on January 17. Sean rapidly intensified into a Category 3-tropical cyclone, marking it the second major tropical cyclone of the year after Dikeledi. [[Cyclone Taliah]] and [[Cyclone Vince (2025)|Cyclone Vince]] formed as well, with the latter rapidly intensifying into a Very Intense Tropical Cyclone in the South-West Indian Ocean, making it the strongest cyclone this month.

===February===
[[File:Zelia 2025-02-13 0000Z.jpg|thumb|[[Cyclone Zelia (2025)|Cyclone Zelia]]]]
February was extremely active. It was the most active month, and one of the third-most active months in any given year on record, with twelve systems forming and seven storms getting named. A total of seven tropical cyclones reached Category 3 strength or higher, the highest number since records began in [[Tropical cyclones in 2003|2003]].

Historically, February is normally similar to January in terms of activity, with most formations being effectively restricted to the Southern Hemisphere (with the exception of the rare Western Pacific disturbance this year). The month also tends to see more strong tropical cyclones forming compared to January, despite seeing marginally fewer overall storms, due to the [[monsoon]] being at its height in the Southern Hemisphere.<ref name="BOM database" /> In the Northern Hemisphere, February is the least active month, with no [[Pacific hurricane|Eastern or Central Pacific tropical cyclone]]s{{EPAC hurricane best track}} and [[1952 Groundhog Day tropical storm|only one]] Atlantic tropical cyclone having ever formed in the month. Even in the Western Pacific, February activity is low: in 2025, the month never saw a typhoon-strength storm, the first being [[Typhoon Higos (2015)|Typhoon Higos]] in 2015.

The month started off active with five systems forming in January and then persisting into February: Faida, 13U, Vince, Taliah, and 05F. [[Cyclone Zelia (2025)|Cyclone Zelia]] formed on February 7 near the [[Kimberley region]], and rapidly intensified into a Category 5 severe tropical cyclone six days later; it then made landfall near [[De Grey, Western Australia|De Grey]] in [[Australia]] as a Category 4 tropical cyclone.<ref>{{cite news|last=Yoon|first=John|url=https://www.nytimes.com/2025/02/14/world/australia/tropical-cyclone-zelia.html|title=Tropical Cyclone Zelia Makes Landfall in Northwest Australia|publisher=The New York Times|date=February 14, 2025|access-date=February 15, 2025|archive-url=https://web.archive.org/web/20250215040927/https://www.nytimes.com/2025/02/14/world/australia/tropical-cyclone-zelia.html|archive-date=February 15, 2025|url-status=live}}</ref> Two tropical cyclones formed in the Australian region on February 20 – Bianca and Alfred – while in the South-West Indian Ocean, two cyclones also formed near Madagascar: Garance and Honde. The former eventually became an intense tropical cyclone on February 27 before making landfall in the northern part of [[Réunion]] the next day as a slightly weaker tropical cyclone.

=== March ===
[[File:Courtney 2025-03-29 1000Z.jpg|thumb|[[Cyclone Courtney (2025)|Cyclone Courtney]]]]
During March, activity tends to be lower than in preceding months. In the Southern Hemisphere, the peak of the season has normally already passed, and the monsoon has begun to weaken, decreasing cyclonic activity, however, the month often sees more intense tropical cyclones than January or February.<ref name="BOM database" /> Meanwhile, in the Northern Hemisphere basins, sea surface temperatures are still far too low to normally support tropical cyclogenesis. The exception is the Western Pacific, which usually sees its first storm, often a weak depression, at some point between January and April.

March was slightly-inactive, featuring five storms, all of them were named. [[Cyclone Alfred (2025)|Cyclone Alfred]], [[Cyclone Honde|Honde]], and [[Cyclone Garance|Garance]] formed in February and persisted into March. The strongest storm of the month is [[2024–25 Australian region cyclone season#Severe Tropical Cyclone Courtney|Cyclone Courtney]]. At the start of the month, [[Cyclone Jude]] caused 21 deaths in Southeastern Africa.

===April===
[[File:Errol 2025-04-16 0520Z.jpg|thumb|[[Cyclone Errol (2025)|Cyclone Errol]]]]
The factors that begin to inhibit Southern Hemisphere cyclone formation in March are even more pronounced in April, with the average number of storms formed being hardly half that of March.<ref name="BOM database" /><ref name="apr" /> However, even this limited activity exceeds the activity in the Northern Hemisphere, which is rare, with the exception of the Western Pacific basin. All [[Pacific typhoon season]]s between [[1998 Pacific typhoon season|1998]] and [[2016 Pacific typhoon season|2016]] saw activity between January and April, although many of these seasons saw only weak tropical depressions.<ref name="JMA BT" /> By contrast, only two [[Atlantic hurricane season]]s during those years saw tropical cyclone formation during that period.{{Atlantic hurricane best track}} With the combination of the decreasing temperatures in the Southern Hemisphere and the still-low temperatures in the Northern Hemisphere, April and May tend to be the least active months worldwide for tropical cyclone formation.<ref name="apr" />

April 2025 was an example of this phenomenon, seeing four storms forming, three being named. The month started off in the Australian basin with the formation of [[Cyclone Errol (2025)|Cyclone Errol]], which would later become the first Category 5 equivalent cyclone of the year, and is the strongest cyclone this month so far. Following that was the formation of [[2024–25 Australian region cyclone season#Tropical Low 30U|Tropical Low 30U]]. In the South Pacific basin, [[Cyclone Tam (2025)|Cyclone Tam]] formed and briefly impacted [[Vanuatu]]. On 20 April, subtropical storm Kanto formed, become the first subtropical cyclone in the South-west Indian Ocean since subtropical storm Issa in April 2022.

The '''2024–25 South-West Indian Ocean cyclone season''' is the current annual cycle of [[tropical cyclone]] and [[subtropical cyclone]] formation in the South-West Indian Ocean. It began on 15 November 2024, and will end on 30 April 2025, with the exception for [[Mauritius]] and the [[Seychelles]], for which it will end on 15 May 2025. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of [[90th meridian east|90°E]] and south of the [[Equator]]. However, tropical cyclones can form year-round with any cyclone forming between 1 July 2024 and 30 June 2025, such as 01, Ancha, and Bheki, will be part of the season. Tropical and subtropical cyclones in this basin are monitored by the [[Regional Specialised Meteorological Centre]] in [[Réunion]] and unofficially by the [[Joint Typhoon Warning Center]].

The first system formed before the official start of the season, Tropical Depression 01, but the disturbance failed to organize into a tropical storm and dissipated on 17 August. In late September, Tropical Storm Ancha formed without making landfall, and a month later, three days before the official start of the season, Tropical Storm Bheki formed, which became the first intense tropical cyclone of the season a few days later, leaving heavy rains in the [[Mascarene Islands]]. In mid-December, Tropical Storm Chido formed and rapidly intensified into a Category 4-equivalent tropical cyclone two days later, then made landfall on [[Agaléga Islands|Agaléga North Island]]. Chido then peaked as a high-end Category 4 equivalent cyclone before weakening down to a Category 3 then eventually to a Category 2 northeast of Madagascar. The cyclone then rapidly intensified back to a Category 4 equivalent cyclone and made landfall on [[Mayotte]], becoming the strongest landfalling cyclone in the island on record. Chido went on to strike Mozambique as a powerful Category 4 equivalent cyclone. Dikeledi formed on 6 January, gradually intensifying over the next four days until making landfalling in Northern Madagascar as a Category 2 equivalent cyclone on 11 January. The cyclone weakened to a tropical storm south of Mayotte before rapidly strengthening back to Category 2 intensity, making landfall near [[Nacala]] at that strength on 13 January.

In late January, two tropical cyclones formed; one of them was the moderate Tropical Storm Faida, which brought heavy rainfall to Madagascar on 5 February. After Faida dissipated, Tropical Cyclone Vince entered the basin from the Australian region on 4 February. Four days later, it became the most intense cyclone of the season and the first very intense tropical cyclone since [[Cyclone Freddy]] two years before. At 12 February, Vince had transitioned to being extratropical. At the same day, Taliah had entered the basin fluctuating between a moderate tropical storm and a strong tropical storm before becoming a post-tropical cyclone at 18 February. Six days later, Garance and Honde had formed, Garance receiving its name the day after. Garance intensified rapidly into an Intense Tropical Cyclone, making landfall at [[Réunion]] at 28 February as a Category 2. Honde brought heavy rainfall to [[Mozambique]] and then southern Madagascar as a Category 1. Jude formed as a disturbance south of the [[Chagos Islands]] on 6 March. It intensified at 8 March, receiving its name. Ivone entered the basin on 8 March and on the same day intensified to a Moderate Tropical Storm and received its name. Jude made landfall in Mozambique as a Category 1 at 10 March. Courtney from the Australian region entered the basin on 29 March, becoming an intense tropical cyclone. After nearly a month of inactivity, on 20 April Subtropical storm Kanto was named reaching a peak intensity of 75 km/h (10 minute sustained) winds with a central pressure of 993 hPa. This was the first subtropical storm named by Meteo France, which added the subtropical cyclone category starting with this cyclone season.

===Preseason/early-season activity===
The season officially started on 15 November 2024; however, the first system, Tropical Depression 01, formed on 15 August, a whole three months before the official start. In late–September, Moderate Tropical Storm Ancha formed on 30 September and dissipated five days later without making landfall. Three days before the official start of the season, Tropical Storm Bheki formed, which days later became the first intense tropical cyclone in the basin. Bheki caused heavy rainfall in parts of the [[Mascarene Islands]] such as [[Réunion]] and [[Rodrigues]]. After the dissipation of Bheki, Tropical Storm Chido formed on 9 December, and two days later became the second intense tropical cyclone of the season. Chido devastated Agaléga, Mayotte, and Mozambique, and caused hundreds of deaths and injuries.

===Peak season activity===
[[File:Garance and Honde 2025-02-28 0730Z.jpg|200px|thumb|right|Two systems active on 28 February near Madagascar: Tropical Cyclone Honde (left) and Intense Tropical Cyclone Garance (right).]]
Cyclone Dikeledi formed near [[Java]], [[Indonesia]] on 30 December 2024, and was named on 9 January. It hit [[Madagascar]] as a tropical cyclone, then [[Mozambique]], fluctuating in strength. It peaked as an intense tropical cyclone on 16 January, setting a record for its southerly location, before weakening and becoming extratropical on 17 January. In late January, Moderate Tropical Storm Elvis formed in the southern [[Mozambique Channel]] where it brought heavy rain to south-western Madagascar specifically in the [[Toliara Province]] but also the [[Morombe District]]. Soon after on 28 January [[RSMC La Réunion]] started to monitor tropical disturbance 07. It strengthened to Tropical Depression 07 the next day and remained that intensity whilst impacting [[Rodrigues]], where a class 2 cyclone warning was issued, and [[Mauritius]] where a class 1 was issued. It also effected Réunion's weather before moving away to the west-north-west towards Madagascar, where it eventually strengthened into Moderate Tropical Storm Faida on 2 February. However, in post-storm analysis Faida was downgraded to tropical depression status.

Early on 4 February, Tropical Cyclone Vince moved into the basin, from the Australian Region. Vince would continue to steadily intensify until 6 February, when Vince underwent rapid intensification, and acquired winds of 155 miles per hour, and a minimum central pressure of 924 millibars. Tropical Cyclone Taliah also moved into the basin from the Australian Region on 12 February at tropical cyclone intensity. On 24 February, two tropical cyclones formed near [[Madagascar]], Garance and Honde, one of which became an intense tropical cyclone three days later. On 24 February, two tropical cyclones formed near Madagascar, Garance and Honde. Garance rapidly intensified, reaching intense tropical cyclone status on 27 February, with peak winds of 110 miles per hour and a minimum central pressure of 951 millibars. Honde, a larger and less intense system, gradually strengthened, reaching tropical cyclone status on 28 February, with peak winds of 75 miles per hour and a minimum central pressure of 968 millibars.

===Late season activity===

Ivone and Jude formed on 8 March, in the far-eastern South-West Indian Ocean and Mozambique channel, respectively. Ivone reached its peak as a Severe Tropical Storm on 9 March. Ivone turned post-tropical on 11 March.
Jude made landfall in Mozambique as a Tropical Cyclone also on 11 March, and dissipated on the same day over Mozambique, but re-emerged as a tropical storm over the Mozambique Channel two days later. On 29 March, Severe Tropical Cyclone Courtney entered in the basin, and later this day it peaked with winds of 125 mph (205 km/h) before weakening far from land. It transitioned into an post-tropical cyclone on 31 March.

After a period of nearly a month with little activity, Meteo France began monitoring a weather system far south of Madagascar that showed potential for subtropical development, and on 20 April, it was classified as a subtropical depression; later that same evening, Madagascar's Meteorological services further upgraded it to a [[subtropical storm]], assigning it the name Kanto, which marked the first subtropical storm named by Meteo France.

On 24 September, the MFR noted that tropical cyclogenesis would be possible in late September due to the passage of an [[equatorial Rossby wave]] and a [[Kelvin wave]], which would help cause the formation of a temporary near-equatorial trough.<ref>{{cite report |url=http://www.meteo.fr/temps/domtom/La_Reunion/webcmrs9.0/anglais/activiteope/bulletins/zcit/ZCITA_202409241212.pdf |title=Bulletin

The MFR upgraded Tropical Depression 06 into Tropical Storm Faida on 28 February.

According to [[Météo-France]], there was generally 30 to 50 mm of rain in the north and east of [[Réunion|Réunion Island]], with higher totals on the mountain slopes reaching 100 to 150 mm and, locally, up to 180 mm in Brûlé, south of [[Saint-Denis, Réunion|Saint-Denis]]. These quantities were not enough to compensate for the rainfall deficit of almost 80% on average on the island over the previous two months.

On 4 February, Severe Tropical Cyclone Vince entered the South-West Indian Ocean basin from the Australian Region. Vince would continue to steadily intensify until the 6 February, when Vince underwent [[rapid intensification]], and acquired 10-minute sustained winds of {{convert|130|mph|km/h|abbr=on|round=5}}, and a minimum central pressure of 930 millibars late on 6 February. The storm fluctuated in intensity until where at 06:00 UTC of 7 February it resumed strengthening.<ref name=bsh>https://www.ssd.noaa.gov/PS/TROP/DATA/ATCF/JTWC/bsh132025.dat</ref> Later that day Vince would be upgraded to a Very Intense Tropical Cyclone.

[[Météo-France]] began monitoring an area of potential development in the southern [[Mozambique Channel]] on 24 February. Unlike Garance, which organised quickly, this system was much larger and more disorganised, requiring more time to develop. Several days before its formation, the system that would become Tropical Cyclone Honde was already bringing heavy and disruptive rainfall to southern [[Mozambique]] and, particularly, [[Madagascar]]. Météo-France officially upgraded Honde to a Moderate Tropical Storm on 26 February. Subsequently, it gradually strengthened to a Severe Tropical Storm the following day, before reaching Tropical Cyclone stage on 28 February, when it made its closest approach to Madagascar.

Honde caused severe damage in Madagascar. 43,200 people were affected, mainly in the Andrefana and Menabe regions. 7,200 homes were damaged and 1,900 homes were destroyed from strong winds and flooding. Three people were killed and 69 were injured during the storm.<ref>{{Cite web |date=6 March 2025 |title=Tropical Cyclone Honde - Feb 2025 {{!}} ReliefWeb |url=https://reliefweb.int/disaster/tc-2025-000025-mdg |access-date=9 March 2025 |website=reliefweb.int |language=en}}</ref>

On 29 March, Severe Tropical Cyclone Courtney entered from the Australian region. The system intensified further to a 140 mph (220 km/h) cyclone with a minimum central pressure of 929 according to Meteo France shortly after its arrival in the basin. Later that day, it started to show signs of weakening due to cooler sea surface temperatures. The Dvorak analysis carried out by the RSMC initially gave winds at 140 mph. The best track has therefore been revised slightly downwards to peaking at 125 mph instead.  Courtney turned into a post-tropical cyclone due to nearby dry air, wind shear, and cooler water while traversing through the Indian Ocean. The remnants of Courtney then travelled between Australia and Antarctica. There were no reports of damages.

Kanto was the first subtropical system to develop in the region since Subtropical Depression Issa during the 2021–22 season. It was also the first to be designated a "subtropical storm" by Meteo France, which was introduced as a category for subtropical cyclones with maximum sustained winds above {{convert|65|km/h|mph|abbr=on}} beginning with the 2024–25 season.<ref>{{cite report|title=Regional Association I — Tropical Cyclone Operational Plan for the South-West Indian Ocean|date=2023|access-date=21 April 2025|publisher=World Meteorological Organization|url=https://wmoomm.sharepoint.com/:b:/s/wmocpdb/EYlTpV0sKLFAjl1s8ktbVBgBLNG3v60mFBTQ9TXnOcZZUw?e=GfpWcm}}</ref>

== Storm names ==
{{Main|Tropical cyclone naming}}
Within the South-West Indian Ocean, tropical depressions and subtropical depressions that are judged to have 10-minute sustained windspeeds of 65 km/h (40 mph) by the [[Regional Specialized Meteorological Center]] on [[Réunion]] island, France (RSMC La Réunion) are usually assigned a name. However, it is the Sub-Regional Tropical Cyclone Advisory Centers in Mauritius and Madagascar who name the systems. The Sub-Regional Tropical Cyclone Advisory Center (Mauritius Meteorological Services) in Mauritius names a storm if it intensifies into a moderate tropical storm between [[55th meridian east|55°E]] and [[90th meridian east|90°E]]. If instead a cyclone intensifies into a moderate tropical storm between [[30th meridian east|30°E]] and [[55th meridian east|55°E]] then the Sub-Regional Tropical Cyclone Advisory Center (Meteo Madagascar) in Madagascar assigns the appropriate name to the storm. Storm names are taken from three pre-determined lists of names, which rotate on a triennial basis, with any names that have been used automatically removed. New names this season are: Ancha, Bheki, Chido, Dikeledi, Elvis, Faida, Garance, Honde, Ivone, Jude, Kanto and Lira. They replaced Ana, Batsirai, Cliff, Dumako, Emnati, Fezile, Gombe, Halima, Issa, Jasmine and Karim during the [[2021–22 South-West Indian Ocean cyclone season|2021–22 season]], and also Letlama, which was not used, but the reason for its removal is unknown.<ref name="SWIO TCOP">{{cite report|author=RA I Tropical Cyclone Committee |publisher=World Meteorological Organization |title=Tropical Cyclone Operational Plan for the South-West Indian Ocean|year=2023|format=PDF |url=https://community.wmo.int/en/tropical-cyclone-operational-plans|archive-url=https://web.archive.org/web/20240702081536/https://www.theedkins.co.uk/storms/RAI_TCC-25_OperationalPlan_WMO-Nr1178_EN.pdf|archive-date=2 July 2024}}</ref>

If a tropical cyclone crosses 90°E into the South-West Indian basin from the [[Tropical cyclone basins#Australian region|Australian region basin]], it will retain the name assigned to it by the [[Australian Bureau of Meteorology]] (BoM). The following storms were named in this manner.<ref>{{cite report |url=http://www.bom.gov.au/cyclone/tropical-cyclone-knowledge-centre/understanding/tc-names/ |title=Tropical cyclone names |date= |publisher=[[Australian Bureau of Meteorology]] |archive-url=https://web.archive.org/web/20221226050506/http://www.bom.gov.au/cyclone/tropical-cyclone-knowledge-centre/understanding/tc-names/ |archive-date=26 December 2022 |access-date=26 December 2022}}</ref>

The '''2024–25 South-West Indian Ocean cyclone season''' is the current annual cycle of [[tropical cyclone]] and [[subtropical cyclone]] formation in the South-West Indian Ocean. It began on 15 November 2024, and will end on 30 April 2025, with the exception for [[Mauritius]] and the [[Seychelles]], for which it will end on 15 May 2025. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of [[90th meridian east|90°E]] and south of the [[Equator]]. However, tropical cyclones can form year-round with any cyclone forming between 1 July 2024 and 30 June 2025, such as 01, Ancha, and Bheki, will be part of the season. Tropical and subtropical cyclones in this basin are monitored by the [[Regional Specialised Meteorological Centre]] in [[Réunion]] and unofficially by the [[Joint Typhoon Warning Center]].

The first system formed before the official start of the season, Tropical Depression 01, but the disturbance failed to organize into a tropical storm and dissipated on 17 August. In late September, Tropical Storm Ancha formed without making landfall, and a month later, three days before the official start of the season, Tropical Storm Bheki formed, which became the first intense tropical cyclone of the season a few days later, leaving heavy rains in the [[Mascarene Islands]]. In mid-December, Tropical Storm Chido formed and rapidly intensified into a Category 4-equivalent tropical cyclone two days later, then made landfall on [[Agaléga Islands|Agaléga North Island]]. Chido then peaked as a high-end Category 4 equivalent cyclone before weakening down to a Category 3 then eventually to a Category 2 northeast of Madagascar. The cyclone then rapidly intensified back to a Category 4 equivalent cyclone and made landfall on [[Mayotte]], becoming the strongest landfalling cyclone in the island on record. Chido went on to strike Mozambique as a powerful Category 4 equivalent cyclone. Dikeledi formed on 6 January, gradually intensifying over the next four days until making landfalling in Northern Madagascar as a Category 2 equivalent cyclone on 11 January. The cyclone weakened to a tropical storm south of Mayotte before rapidly strengthening back to Category 2 intensity, making landfall near [[Nacala]] at that strength on 13 January.

In late January, two tropical cyclones formed; one of them was the moderate Tropical Storm Faida, which brought heavy rainfall to Madagascar on 5 February. After Faida dissipated, Tropical Cyclone Vince entered the basin from the Australian region on 4 February. Four days later, it became the most intense cyclone of the season and the first very intense tropical cyclone since [[Cyclone Freddy]] two years before. At 12 February, Vince had transitioned to being extratropical. At the same day, Taliah had entered the basin fluctuating between a moderate tropical storm and a strong tropical storm before becoming a post-tropical cyclone at 18 February. Six days later, Garance and Honde had formed, Garance receiving its name the day after. Garance intensified rapidly into an Intense Tropical Cyclone, making landfall at [[Réunion]] at 28 February as a Category 2. Honde brought heavy rainfall to [[Mozambique]] and then southern Madagascar as a Category 1. Jude formed as a disturbance south of the [[Chagos Islands]] on 6 March. It intensified at 8 March, receiving its name. Ivone entered the basin on 8 March and on the same day intensified to a Moderate Tropical Storm and received its name. Jude made landfall in Mozambique as a Category 1 at 10 March. Courtney from the Australian region entered the basin on 29 March, becoming an intense tropical cyclone. After nearly a month of inactivity, on 20 April Subtropical storm Kanto was named reaching a peak intensity of 75 km/h (10 minute sustained) winds with a central pressure of 993 hPa. This was the first subtropical storm named by Meteo France, which added the subtropical cyclone category starting with this cyclone season.

===Preseason/early-season activity===
The season officially started on 15 November 2024; however, the first system, Tropical Depression 01, formed on 15 August, a whole three months before the official start. In late–September, Moderate Tropical Storm Ancha formed on 30 September and dissipated five days later without making landfall. Three days before the official start of the season, Tropical Storm Bheki formed, which days later became the first intense tropical cyclone in the basin. Bheki caused heavy rainfall in parts of the [[Mascarene Islands]] such as [[Réunion]] and [[Rodrigues]]. After the dissipation of Bheki, Tropical Storm Chido formed on 9 December, and two days later became the second intense tropical cyclone of the season. Chido devastated Agaléga, Mayotte, and Mozambique, and caused hundreds of deaths and injuries.

===Peak season activity===
[[File:Garance and Honde 2025-02-28 0730Z.jpg|200px|thumb|right|Two systems active on 28 February near Madagascar: Tropical Cyclone Honde (left) and Intense Tropical Cyclone Garance (right).]]
Cyclone Dikeledi formed near [[Java]], [[Indonesia]] on 30 December 2024, and was named on 9 January. It hit [[Madagascar]] as a tropical cyclone, then [[Mozambique]], fluctuating in strength. It peaked as an intense tropical cyclone on 16 January, setting a record for its southerly location, before weakening and becoming extratropical on 17 January. In late January, Moderate Tropical Storm Elvis formed in the southern [[Mozambique Channel]] where it brought heavy rain to south-western Madagascar specifically in the [[Toliara Province]] but also the [[Morombe District]]. Soon after on 28 January [[RSMC La Réunion]] started to monitor tropical disturbance 07. It strengthened to Tropical Depression 07 the next day and remained that intensity whilst impacting [[Rodrigues]], where a class 2 cyclone warning was issued, and [[Mauritius]] where a class 1 was issued. It also effected Réunion's weather before moving away to the west-north-west towards Madagascar, where it eventually strengthened into Moderate Tropical Storm Faida on 2 February. However, in post-storm analysis Faida was downgraded to tropical depression status.

Early on 4 February, Tropical Cyclone Vince moved into the basin, from the Australian Region. Vince would continue to steadily intensify until 6 February, when Vince underwent rapid intensification, and acquired winds of 155 miles per hour, and a minimum central pressure of 924 millibars. Tropical Cyclone Taliah also moved into the basin from the Australian Region on 12 February at tropical cyclone intensity. On 24 February, two tropical cyclones formed near [[Madagascar]], Garance and Honde, one of which became an intense tropical cyclone three days later. On 24 February, two tropical cyclones formed near Madagascar, Garance and Honde. Garance rapidly intensified, reaching intense tropical cyclone status on 27 February, with peak winds of 110 miles per hour and a minimum central pressure of 951 millibars. Honde, a larger and less intense system, gradually strengthened, reaching tropical cyclone status on 28 February, with peak winds of 75 miles per hour and a minimum central pressure of 968 millibars.

===Late season activity===

Ivone and Jude formed on 8 March, in the far-eastern South-West Indian Ocean and Mozambique channel, respectively. Ivone reached its peak as a Severe Tropical Storm on 9 March. Ivone turned post-tropical on 11 March.
Jude made landfall in Mozambique as a Tropical Cyclone also on 11 March, and dissipated on the same day over Mozambique, but re-emerged as a tropical storm over the Mozambique Channel two days later. On 29 March, Severe Tropical Cyclone Courtney entered in the basin, and later this day it peaked with winds of 125 mph (205 km/h) before weakening far from land. It transitioned into an post-tropical cyclone on 31 March.

After a period of nearly a month with little activity, Meteo France began monitoring a weather system far south of Madagascar that showed potential for subtropical development, and on 20 April, it was classified as a subtropical depression; later that same evening, Madagascar's Meteorological services further upgraded it to a [[subtropical storm]], assigning it the name Kanto, which marked the first subtropical storm named by Meteo France.

On 12 February, Tropical Cyclone Taliah crossed over from the Australian region at [[List of South-West Indian Ocean moderate tropical storms|moderate tropical storm]] intensity, having formed there on 31 January. Almost immediately, Taliah reintensified into a tropical cyclone before weakening into a moderate tropical storm the next day while moving southwest.<ref>{{cite web|url=https://www.ssd.noaa.gov/PS/TROP/DATA/ATCF/JTWC/bsh142025.dat|title=Severe Tropical Cyclone Taliah Best Track|work=Joint Typhoon Warning Center|publisher=National Oceanic and Atmospheric Administration|access-date=12 February 2025}}</ref>

Taliah then continued on its path while varying in intensity between moderate and strong tropical storm before becoming a [[post-tropical cyclone]] on 18 February near 31°S latitude over increasingly cooler waters and showing very sporadic storm activity far from the center.

[[Météo-France]] started monitoring what would become Garance on 24 February. It subsequently received the name Garance, and was upgraded to a Moderate Tropical Storm on 25 February. From 26 to 27 February, Garance rapidly intensified into an Intense Tropical Cyclone. The purple alert was issued in Reunion on 28 February, as the cyclone approached.<ref>{{Cite web|url=https://www.france24.com/en/asia-pacific/20250228-cyclone-garance-puts-mauritius-la-reunion-on-high-alert |title=La Reunion island under 'purple alert' as Cyclone Garance approaches |access-date=28 February 2025 |website=France 24|date=28 February 2025 }}</ref> On 28 February, Intense Tropical Cyclone Garance made landfall at 10:00 RET in the morning near [[Sainte-Suzanne, Réunion|Sainte-Suzanne]], in the north of [[Réunion]] at Tropical Cyclone intensity.

[[Météo-France]] began monitoring an area of potential development in the southern [[Mozambique Channel]] on 24 February. Unlike Garance, which organised quickly, this system was much larger and more disorganised, requiring more time to develop. Several days before its formation, the system that would become Tropical Cyclone Honde was already bringing heavy and disruptive rainfall to southern [[Mozambique]] and, particularly, [[Madagascar]]. Météo-France officially upgraded Honde to a Moderate Tropical Storm on 26 February. Subsequently, it gradually strengthened to a Severe Tropical Storm the following day, before reaching Tropical Cyclone stage on 28 February, when it made its closest approach to Madagascar.

Honde caused severe damage in Madagascar. 43,200 people were affected, mainly in the Andrefana and Menabe regions. 7,200 homes were damaged and 1,900 homes were destroyed from strong winds and flooding. Three people were killed and 69 were injured during the storm.<ref>{{Cite web |date=6 March 2025 |title=Tropical Cyclone Honde - Feb 2025 {{!}} ReliefWeb |url=https://reliefweb.int/disaster/tc-2025-000025-mdg |access-date=9 March 2025 |website=reliefweb.int |language=en}}</ref>

Honde weakened into a tropical storm after passing Madagascar. Before turning extratropical, Honde briefly strengthened into a severe tropical storm on 5 March in the Southern Indian Ocean.

[[Météo-France]] began monitoring a disturbance south of the [[Chagos Islands]] on 6 March. It got upgraded to a depression a day later. It was then upgraded to a Moderate Tropical Storm on 8 March, where it got the name Jude. The tropical cyclone made landfall in Cabaceira, [[Mozambique]] as a Category 1 at 10 March.

In the municipality of [[Nacala-Porto]], six fatalities were recorded.<ref>{{Cite web |title=Mozambique: Tropical storm leaves fatalities and trail of destruction in Nampula |url=https://clubofmozambique.com/news/mozambique-tropical-storm-leaves-fatalities-and-trail-of-destruction-in-nampula-277563/ |access-date=11 March 2025 |website=Mozambique |language=en-US}}</ref> Overall, the cyclone caused 16 fatalities in Mozambique,<ref name=death-Jude-Mozambique>{{Cite web |last=Presse |first=AFP-Agence France |title=Mozambique Cyclone Death Toll Rises To 16 |url=https://www.barrons.com/articles/mozambique-cyclone-death-toll-rises-to-16-0ea12132 |access-date=15 March 2025 |website=barrons |language=en-us}}</ref> 2 in Madagascar,<ref name=death-Jude-Madagascar>{{cite web |language=en |url=https://reliefweb.int/report/madagascar/southern-africa-tropical-cyclone-jude-flash-update-no-1-11-march-2025 |title=Southern Africa: Tropical Cyclone Jude Flash Update No. 1 (as of 11 March 2025) |author=[[OCHA]] |date=11 March 2025 |publisher=ReliefWeb |access-date=11 March 2025}}</ref><ref name=OCHA-3-Jude>{{cite web |language=en |url=https://reliefweb.int/report/madagascar/southern-africa-tropical-storm-jude-flash-update-no-2-18-march-2025 |title=Southern Africa: Tropical Storm Jude Flash Update No. 2 (as of 18 March 2025) |author=[[OCHA]] |date=18 March 2025 |publisher=ReliefWeb |access-date=18 March 2025}}</ref> and 3 in Malawi.<ref name=death-Malawi-Jude>{{cite news |language=en |author1=Jamal Jamal |title=Tropical Cyclone Jude kills 9 people in Mozambique, Malawi |agency=[[Anadolu Agency]] |date= 14 March 2025 |url=https://www.aa.com.tr/en/asia-pacific/tropical-cyclone-jude-kills-9-people-in-mozambique-malawi/3509203 |access-date=15 March 2025

Meteo France started monitoring this system in the extreme eastern reaches of the basin on 8 March. It was upgraded to Moderate Tropical Storm Ivone the same day.

Ivone sustained its strength for a few days, as a tropical storm before dissipating on 11 March.

=== Intense Tropical Cyclone Kanto-Courtney ===

}}

On 29 March, Severe Tropical Cyclone Courtney entered from the Australian region. The system intensified further to a 140 mph (220 km/h) cyclone with a minimum central pressure of 929 according to Meteo France shortly after its arrival in the basin. Later that day, it started to show signs of weakening due to cooler sea surface temperatures. The Dvorak analysis carried out by the RSMC initially gave winds at 140 mph. The best track has therefore been revised slightly downwards to peaking at 125 mph instead.  Courtney turned into a post-tropical cyclone due to nearby dry air, wind shear, and cooler water while traversing through the Indian Ocean. The remnants of Courtney then travelled between Australia and Antarctica. There were no reports of damages.

Meteo France began monitoring an extratropical system hundreds of miles south of [[Madagascar]]. On the evening of 20 April, the system transitioned into a subtropical storm, thus receiving the name Kanto by Madagascar Meteorological services.<ref>http://metservice.intnet.mu/synoptic-chart.php</ref>

Kanto was the first subtropical system to develop in the region since Subtropical Depression Issa during the 2021–22 season. It was also the first to be designated a "subtropical storm" by Meteo France, which was introduced as a category for subtropical cyclones with maximum sustained winds above {{convert|65|km/h|mph|abbr=on}} beginning with the 2024–25 season.<ref>{{cite report|title=Regional Association I — Tropical Cyclone Operational Plan for the South-West Indian Ocean|date=2023|access-date=21 April 2025|publisher=World Meteorological Organization|url=https://wmoomm.sharepoint.com/:b:/s/wmocpdb/EYlTpV0sKLFAjl1s8ktbVBgBLNG3v60mFBTQ9TXnOcZZUw?e=GfpWcm}}</ref>

== Storm names ==
{{Main|Tropical cyclone naming}}
Within the South-West Indian Ocean, tropical depressions and subtropical depressions that are judged to have 10-minute sustained windspeeds of 65 km/h (40 mph) by the [[Regional Specialized Meteorological Center]] on [[Réunion]] island, France (RSMC La Réunion) are usually assigned a name. However, it is the Sub-Regional Tropical Cyclone Advisory Centers in Mauritius and Madagascar who name the systems. The Sub-Regional Tropical Cyclone Advisory Center (Mauritius Meteorological Services) in Mauritius names a storm if it intensifies into a moderate tropical storm between [[55th meridian east|55°E]] and [[90th meridian east|90°E]]. If instead a cyclone intensifies into a moderate tropical storm between [[30th meridian east|30°E]] and [[55th meridian east|55°E]] then the Sub-Regional Tropical Cyclone Advisory Center (Meteo Madagascar) in Madagascar assigns the appropriate name to the storm. Storm names are taken from three pre-determined lists of names, which rotate on a triennial basis, with any names that have been used automatically removed. New names this season are: Ancha, Bheki, Chido, Dikeledi, Elvis, Faida, Garance, Honde, Ivone, Jude, Kanto and Lira. They replaced Ana, Batsirai, Cliff, Dumako, Emnati, Fezile, Gombe, Halima, Issa, Jasmine and Karim during the [[2021–22 South-West Indian Ocean cyclone season|2021–22 season]], and also Letlama, which was not used, but the reason for its removal is unknown.<ref name="SWIO TCOP">{{cite report|author=RA I Tropical Cyclone Committee |publisher=World Meteorological Organization |title=Tropical Cyclone Operational Plan for the South-West Indian Ocean|year=2023|format=PDF |url=https://community.wmo.int/en/tropical-cyclone-operational-plans|archive-url=https://web.archive.org/web/20240702081536/https://www.theedkins.co.uk/storms/RAI_TCC-25_OperationalPlan_WMO-Nr1178_EN.pdf|archive-date=2 July 2024}}</ref>

The '''2024–25 South-West Indian Ocean cyclone season''' is the current annual cycle of [[tropical cyclone]] and [[subtropical cyclone]] formation in the South-West Indian Ocean. It began on 15 November 2024, and will end on 30 April 2025, with the exception for [[Mauritius]] and the [[Seychelles]], for which it will end on 15 May 2025. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of [[90th meridian east|90°E]] and south of the [[Equator]]. However, tropical cyclones can form year-round with any cyclone forming between 1 July 2024 and 30 June 2025, such as 01, Ancha, and Bheki, will be part of the season. Tropical and subtropical cyclones in this basin are monitored by the [[Regional Specialised Meteorological Centre]] in [[Réunion]] and unofficially by the [[Joint Typhoon Warning Center]].

The first system formed before the official start of the season, Tropical Depression 01, but the disturbance failed to organize into a tropical storm and dissipated on 17 August. In late September, Tropical Storm Ancha formed without making landfall, and a month later, three days before the official start of the season, Tropical Storm Bheki formed, which became the first intense tropical cyclone of the season a few days later, leaving heavy rains in the [[Mascarene Islands]]. In mid-December, Tropical Storm Chido formed and rapidly intensified into a Category 4-equivalent tropical cyclone two days later, then made landfall on [[Agaléga Islands|Agaléga North Island]]. Chido then peaked as a high-end Category 4 equivalent cyclone before weakening down to a Category 3 then eventually to a Category 2 northeast of Madagascar. The cyclone then rapidly intensified back to a Category 4 equivalent cyclone and made landfall on [[Mayotte]], becoming the strongest landfalling cyclone in the island on record. Chido went on to strike Mozambique as a powerful Category 4 equivalent cyclone. Dikeledi formed on 6 January, gradually intensifying over the next four days until making landfalling in Northern Madagascar as a Category 2 equivalent cyclone on 11 January. The cyclone weakened to a tropical storm south of Mayotte before rapidly strengthening back to Category 2 intensity, making landfall near [[Nacala]] at that strength on 13 January.

In late January, two tropical cyclones formed; one of them was the moderate Tropical Storm Faida, which brought heavy rainfall to Madagascar on 5 February. After Faida dissipated, Tropical Cyclone Vince entered the basin from the Australian region on 4 February. Four days later, it became the most intense cyclone of the season and the first very intense tropical cyclone since [[Cyclone Freddy]] two years before. At 12 February, Vince had transitioned to being extratropical. At the same day, Taliah had entered the basin fluctuating between a moderate tropical storm and a strong tropical storm before becoming a post-tropical cyclone at 18 February. Six days later, Garance and Honde had formed, Garance receiving its name the day after. Garance intensified rapidly into an Intense Tropical Cyclone, making landfall at [[Réunion]] at 28 February as a Category 2. Honde brought heavy rainfall to [[Mozambique]] and then southern Madagascar as a Category 1. Jude formed as a disturbance south of the [[Chagos Islands]] on 6 March. It intensified at 8 March, receiving its name. Ivone entered the basin on 8 March and on the same day intensified to a Moderate Tropical Storm and received its name. Jude made landfall in Mozambique as a Category 1 at 10 March. Courtney from the Australian region entered the basin on 29 March, becoming an intense tropical cyclone. After nearly a month of inactivity, on 20 April Subtropical storm Kanto was named reaching a peak intensity of 75 km/h (10 minute sustained) winds with a central pressure of 993 hPa. This was the first subtropical storm named by Meteo France, which added the subtropical cyclone category starting with this cyclone season.

===Preseason/early-season activity===
The season officially started on 15 November 2024; however, the first system, Tropical Depression 01, formed on 15 August, a whole three months before the official start. In late–September, Moderate Tropical Storm Ancha formed on 30 September and dissipated five days later without making landfall. Three days before the official start of the season, Tropical Storm Bheki formed, which days later became the first intense tropical cyclone in the basin. Bheki caused heavy rainfall in parts of the [[Mascarene Islands]] such as [[Réunion]] and [[Rodrigues]]. After the dissipation of Bheki, Tropical Storm Chido formed on 9 December, and two days later became the second intense tropical cyclone of the season. Chido devastated Agaléga, Mayotte, and Mozambique, and caused hundreds of deaths and injuries.

===Peak season activity===
[[File:Garance and Honde 2025-02-28 0730Z.jpg|200px|thumb|right|Two systems active on 28 February near Madagascar: Tropical Cyclone Honde (left) and Intense Tropical Cyclone Garance (right).]]
Cyclone Dikeledi formed near [[Java]], [[Indonesia]] on 30 December 2024, and was named on 9 January. It hit [[Madagascar]] as a tropical cyclone, then [[Mozambique]], fluctuating in strength. It peaked as an intense tropical cyclone on 16 January, setting a record for its southerly location, before weakening and becoming extratropical on 17 January. In late January, Moderate Tropical Storm Elvis formed in the southern [[Mozambique Channel]] where it brought heavy rain to south-western Madagascar specifically in the [[Toliara Province]] but also the [[Morombe District]]. Soon after on 28 January [[RSMC La Réunion]] started to monitor tropical disturbance 07. It strengthened to Tropical Depression 07 the next day and remained that intensity whilst impacting [[Rodrigues]], where a class 2 cyclone warning was issued, and [[Mauritius]] where a class 1 was issued. It also effected Réunion's weather before moving away to the west-north-west towards Madagascar, where it eventually strengthened into Moderate Tropical Storm Faida on 2 February. However, in post-storm analysis Faida was downgraded to tropical depression status.

Early on 4 February, Tropical Cyclone Vince moved into the basin, from the Australian Region. Vince would continue to steadily intensify until 6 February, when Vince underwent rapid intensification, and acquired winds of 155 miles per hour, and a minimum central pressure of 924 millibars. Tropical Cyclone Taliah also moved into the basin from the Australian Region on 12 February at tropical cyclone intensity. On 24 February, two tropical cyclones formed near [[Madagascar]], Garance and Honde, one of which became an intense tropical cyclone three days later. On 24 February, two tropical cyclones formed near Madagascar, Garance and Honde. Garance rapidly intensified, reaching intense tropical cyclone status on 27 February, with peak winds of 110 miles per hour and a minimum central pressure of 951 millibars. Honde, a larger and less intense system, gradually strengthened, reaching tropical cyclone status on 28 February, with peak winds of 75 miles per hour and a minimum central pressure of 968 millibars.

===Late season activity===

Ivone and Jude formed on 8 March, in the far-eastern South-West Indian Ocean and Mozambique channel, respectively. Ivone reached its peak as a Severe Tropical Storm on 9 March. Ivone turned post-tropical on 11 March.
Jude made landfall in Mozambique as a Tropical Cyclone also on 11 March, and dissipated on the same day over Mozambique, but re-emerged as a tropical storm over the Mozambique Channel two days later. On 29 March, Severe Tropical Cyclone Courtney entered in the basin, and later this day it peaked with winds of 125 mph (205 km/h) before weakening far from land. It transitioned into an post-tropical cyclone on 31 March.

After a period of nearly a month with little activity, Meteo France began monitoring a weather system far south of Madagascar that showed potential for subtropical development, and on 20 April, it was classified as a subtropical depression; later that same evening, Madagascar's Meteorological services further upgraded it to a [[subtropical storm]], assigning it the name Kanto, which marked the first subtropical storm named by Meteo France.

On 24 September, the MFR noted that tropical cyclogenesis would be possible in late September due to the passage of an [[equatorial Rossby wave]] and a [[Kelvin wave]], which would help cause the formation of a temporary near-equatorial trough.<ref>{{cite report |url=http://www.meteo.fr/temps/domtom/La_Reunion/webcmrs9.0/anglais/activiteope/bulletins/zcit/ZCITA_202409241212.pdf |title=Bulletin

The MFR upgraded Tropical Depression 06 into Tropical Storm Faida on 28 February.

According to [[Météo-France]], there was generally 30 to 50 mm of rain in the north and east of [[Réunion|Réunion Island]], with higher totals on the mountain slopes reaching 100 to 150 mm and, locally, up to 180 mm in Brûlé, south of [[Saint-Denis, Réunion|Saint-Denis]]. These quantities were not enough to compensate for the rainfall deficit of almost 80% on average on the island over the previous two months.

On 4 February, Severe Tropical Cyclone Vince entered the South-West Indian Ocean basin from the Australian Region. Vince would continue to steadily intensify until the 6 February, when Vince underwent [[rapid intensification]], and acquired 10-minute sustained winds of {{convert|130|mph|km/h|abbr=on|round=5}}, and a minimum central pressure of 930 millibars late on 6 February. The storm fluctuated in intensity until where at 06:00 UTC of 7 February it resumed strengthening.<ref name=bsh>https://www.ssd.noaa.gov/PS/TROP/DATA/ATCF/JTWC/bsh132025.dat</ref> Later that day Vince would be upgraded to a Very Intense Tropical Cyclone.

[[Météo-France]] began monitoring an area of potential development in the southern [[Mozambique Channel]] on 24 February. Unlike Garance, which organised quickly, this system was much larger and more disorganised, requiring more time to develop. Several days before its formation, the system that would become Tropical Cyclone Honde was already bringing heavy and disruptive rainfall to southern [[Mozambique]] and, particularly, [[Madagascar]]. Météo-France officially upgraded Honde to a Moderate Tropical Storm on 26 February. Subsequently, it gradually strengthened to a Severe Tropical Storm the following day, before reaching Tropical Cyclone stage on 28 February, when it made its closest approach to Madagascar.

Honde caused severe damage in Madagascar. 43,200 people were affected, mainly in the Andrefana and Menabe regions. 7,200 homes were damaged and 1,900 homes were destroyed from strong winds and flooding. Three people were killed and 69 were injured during the storm.<ref>{{Cite web |date=6 March 2025 |title=Tropical Cyclone Honde - Feb 2025 {{!}} ReliefWeb |url=https://reliefweb.int/disaster/tc-2025-000025-mdg |access-date=9 March 2025 |website=reliefweb.int |language=en}}</ref>

On 29 March, Severe Tropical Cyclone Courtney entered from the Australian region. The system intensified further to a 140 mph (220 km/h) cyclone with a minimum central pressure of 929 according to Meteo France shortly after its arrival in the basin. Later that day, it started to show signs of weakening due to cooler sea surface temperatures. The Dvorak analysis carried out by the RSMC initially gave winds at 140 mph. The best track has therefore been revised slightly downwards to peaking at 125 mph instead.  Courtney turned into a post-tropical cyclone due to nearby dry air, wind shear, and cooler water while traversing through the Indian Ocean. The remnants of Courtney then travelled between Australia and Antarctica. There were no reports of damages.

Kanto was the first subtropical system to develop in the region since Subtropical Depression Issa during the 2021–22 season. It was also the first to be designated a "subtropical storm" by Meteo France, which was introduced as a category for subtropical cyclones with maximum sustained winds above {{convert|65|km/h|mph|abbr=on}} beginning with the 2024–25 season.<ref>{{cite report|title=Regional Association I — Tropical Cyclone Operational Plan for the South-West Indian Ocean|date=2023|access-date=21 April 2025|publisher=World Meteorological Organization|url=https://wmoomm.sharepoint.com/:b:/s/wmocpdb/EYlTpV0sKLFAjl1s8ktbVBgBLNG3v60mFBTQ9TXnOcZZUw?e=GfpWcm}}</ref>

== Storm names ==
{{Main|Tropical cyclone naming}}
Within the South-West Indian Ocean, tropical depressions and subtropical depressions that are judged to have 10-minute sustained windspeeds of 65 km/h (40 mph) by the [[Regional Specialized Meteorological Center]] on [[Réunion]] island, France (RSMC La Réunion) are usually assigned a name. However, it is the Sub-Regional Tropical Cyclone Advisory Centers in Mauritius and Madagascar who name the systems. The Sub-Regional Tropical Cyclone Advisory Center (Mauritius Meteorological Services) in Mauritius names a storm if it intensifies into a moderate tropical storm between [[55th meridian east|55°E]] and [[90th meridian east|90°E]]. If instead a cyclone intensifies into a moderate tropical storm between [[30th meridian east|30°E]] and [[55th meridian east|55°E]] then the Sub-Regional Tropical Cyclone Advisory Center (Meteo Madagascar) in Madagascar assigns the appropriate name to the storm. Storm names are taken from three pre-determined lists of names, which rotate on a triennial basis, with any names that have been used automatically removed. New names this season are: Ancha, Bheki, Chido, Dikeledi, Elvis, Faida, Garance, Honde, Ivone, Jude, Kanto and Lira. They replaced Ana, Batsirai, Cliff, Dumako, Emnati, Fezile, Gombe, Halima, Issa, Jasmine and Karim during the [[2021–22 South-West Indian Ocean cyclone season|2021–22 season]], and also Letlama, which was not used, but the reason for its removal is unknown.<ref name="SWIO TCOP">{{cite report|author=RA I Tropical Cyclone Committee |publisher=World Meteorological Organization |title=Tropical Cyclone Operational Plan for the South-West Indian Ocean|year=2023|format=PDF |url=https://community.wmo.int/en/tropical-cyclone-operational-plans|archive-url=https://web.archive.org/web/20240702081536/https://www.theedkins.co.uk/storms/RAI_TCC-25_OperationalPlan_WMO-Nr1178_EN.pdf|archive-date=2 July 2024}}</ref>

If a tropical cyclone crosses 90°E into the South-West Indian basin from the [[Tropical cyclone basins#Australian region|Australian region basin]], it will retain the name assigned to it by the [[Australian Bureau of Meteorology]] (BoM). The following storms were named in this manner.<ref>{{cite report |url=http://www.bom.gov.au/cyclone/tropical-cyclone-knowledge-centre/understanding/tc-names/ |title=Tropical cyclone names |date= |publisher=[[Australian Bureau of Meteorology]] |archive-url=https://web.archive.org/web/20221226050506/http://www.bom.gov.au/cyclone/tropical-cyclone-knowledge-centre/understanding/tc-names/ |archive-date=26 December 2022 |access-date=26 December 2022}}</ref>

The '''2024–25 South-West Indian Ocean cyclone season''' is the current annual cycle of [[tropical cyclone]] and [[subtropical cyclone]] formation in the South-West Indian Ocean. It began on 15 November 2024, and will end on 30 April 2025, with the exception for [[Mauritius]] and the [[Seychelles]], for which it will end on 15 May 2025. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of [[90th meridian east|90°E]] and south of the [[Equator]]. However, tropical cyclones can form year-round with any cyclone forming between 1 July 2024 and 30 June 2025, such as 01, Ancha, and Bheki, will be part of the season. Tropical and subtropical cyclones in this basin are monitored by the [[Regional Specialised Meteorological Centre]] in [[Réunion]] and unofficially by the [[Joint Typhoon Warning Center]].

The first system formed before the official start of the season, Tropical Depression 01, but the disturbance failed to organize into a tropical storm and dissipated on 17 August. In late September, Tropical Storm Ancha formed without making landfall, and a month later, three days before the official start of the season, Tropical Storm Bheki formed, which became the first intense tropical cyclone of the season a few days later, leaving heavy rains in the [[Mascarene Islands]]. In mid-December, Tropical Storm Chido formed and rapidly intensified into a Category 4-equivalent tropical cyclone two days later, then made landfall on [[Agaléga Islands|Agaléga North Island]]. Chido then peaked as a high-end Category 4 equivalent cyclone before weakening down to a Category 3 then eventually to a Category 2 northeast of Madagascar. The cyclone then rapidly intensified back to a Category 4 equivalent cyclone and made landfall on [[Mayotte]], becoming the strongest landfalling cyclone in the island on record. Chido went on to strike Mozambique as a powerful Category 4 equivalent cyclone. Dikeledi formed on 6 January, gradually intensifying over the next four days until making landfalling in Northern Madagascar as a Category 2 equivalent cyclone on 11 January. The cyclone weakened to a tropical storm south of Mayotte before rapidly strengthening back to Category 2 intensity, making landfall near [[Nacala]] at that strength on 13 January.

In late January, two tropical cyclones formed; one of them was the moderate Tropical Storm Faida, which brought heavy rainfall to Madagascar on 5 February. After Faida dissipated, Tropical Cyclone Vince entered the basin from the Australian region on 4 February. Four days later, it became the most intense cyclone of the season and the first very intense tropical cyclone since [[Cyclone Freddy]] two years before. At 12 February, Vince had transitioned to being extratropical. At the same day, Taliah had entered the basin fluctuating between a moderate tropical storm and a strong tropical storm before becoming a post-tropical cyclone at 18 February. Six days later, Garance and Honde had formed, Garance receiving its name the day after. Garance intensified rapidly into an Intense Tropical Cyclone, making landfall at [[Réunion]] at 28 February as a Category 2. Honde brought heavy rainfall to [[Mozambique]] and then southern Madagascar as a Category 1. Jude formed as a disturbance south of the [[Chagos Islands]] on 6 March. It intensified at 8 March, receiving its name. Ivone entered the basin on 8 March and on the same day intensified to a Moderate Tropical Storm and received its name. Jude made landfall in Mozambique as a Category 1 at 10 March. Courtney from the Australian region entered the basin on 29 March, becoming an intense tropical cyclone. After nearly a month of inactivity, on 20 April Subtropical storm Kanto was named reaching a peak intensity of 75 km/h (10 minute sustained) winds with a central pressure of 993 hPa. This was the first subtropical storm named by Meteo France, which added the subtropical cyclone category starting with this cyclone season.

===Preseason/early-season activity===
The season officially started on 15 November 2024; however, the first system, Tropical Depression 01, formed on 15 August, a whole three months before the official start. In late–September, Moderate Tropical Storm Ancha formed on 30 September and dissipated five days later without making landfall. Three days before the official start of the season, Tropical Storm Bheki formed, which days later became the first intense tropical cyclone in the basin. Bheki caused heavy rainfall in parts of the [[Mascarene Islands]] such as [[Réunion]] and [[Rodrigues]]. After the dissipation of Bheki, Tropical Storm Chido formed on 9 December, and two days later became the second intense tropical cyclone of the season. Chido devastated Agaléga, Mayotte, and Mozambique, and caused hundreds of deaths and injuries.

===Peak season activity===
[[File:Garance and Honde 2025-02-28 0730Z.jpg|200px|thumb|right|Two systems active on 28 February near Madagascar: Tropical Cyclone Honde (left) and Intense Tropical Cyclone Garance (right).]]
Cyclone Dikeledi formed near [[Java]], [[Indonesia]] on 30 December 2024, and was named on 9 January. It hit [[Madagascar]] as a tropical cyclone, then [[Mozambique]], fluctuating in strength. It peaked as an intense tropical cyclone on 16 January, setting a record for its southerly location, before weakening and becoming extratropical on 17 January. In late January, Moderate Tropical Storm Elvis formed in the southern [[Mozambique Channel]] where it brought heavy rain to south-western Madagascar specifically in the [[Toliara Province]] but also the [[Morombe District]]. Soon after on 28 January [[RSMC La Réunion]] started to monitor tropical disturbance 07. It strengthened to Tropical Depression 07 the next day and remained that intensity whilst impacting [[Rodrigues]], where a class 2 cyclone warning was issued, and [[Mauritius]] where a class 1 was issued. It also effected Réunion's weather before moving away to the west-north-west towards Madagascar, where it eventually strengthened into Moderate Tropical Storm Faida on 2 February. However, in post-storm analysis Faida was downgraded to tropical depression status.

Early on 4 February, Tropical Cyclone Vince moved into the basin, from the Australian Region. Vince would continue to steadily intensify until 6 February, when Vince underwent rapid intensification, and acquired winds of 155 miles per hour, and a minimum central pressure of 924 millibars. Tropical Cyclone Taliah also moved into the basin from the Australian Region on 12 February at tropical cyclone intensity. On 24 February, two tropical cyclones formed near [[Madagascar]], Garance and Honde, one of which became an intense tropical cyclone three days later. On 24 February, two tropical cyclones formed near Madagascar, Garance and Honde. Garance rapidly intensified, reaching intense tropical cyclone status on 27 February, with peak winds of 110 miles per hour and a minimum central pressure of 951 millibars. Honde, a larger and less intense system, gradually strengthened, reaching tropical cyclone status on 28 February, with peak winds of 75 miles per hour and a minimum central pressure of 968 millibars.

===Late season activity===

Ivone and Jude formed on 8 March, in the far-eastern South-West Indian Ocean and Mozambique channel, respectively. Ivone reached its peak as a Severe Tropical Storm on 9 March. Ivone turned post-tropical on 11 March.
Jude made landfall in Mozambique as a Tropical Cyclone also on 11 March, and dissipated on the same day over Mozambique, but re-emerged as a tropical storm over the Mozambique Channel two days later. On 29 March, Severe Tropical Cyclone Courtney entered in the basin, and later this day it peaked with winds of 125 mph (205 km/h) before weakening far from land. It transitioned into an post-tropical cyclone on 31 March.

After a period of nearly a month with little activity, Meteo France began monitoring a weather system far south of Madagascar that showed potential for subtropical development, and on 20 April, it was classified as a subtropical depression; later that same evening, Madagascar's Meteorological services further upgraded it to a [[subtropical storm]], assigning it the name Kanto, which marked the first subtropical storm named by Meteo France.

On 12 February, Tropical Cyclone Taliah crossed over from the Australian region at [[List of South-West Indian Ocean moderate tropical storms|moderate tropical storm]] intensity, having formed there on 31 January. Almost immediately, Taliah reintensified into a tropical cyclone before weakening into a moderate tropical storm the next day while moving southwest.<ref>{{cite web|url=https://www.ssd.noaa.gov/PS/TROP/DATA/ATCF/JTWC/bsh142025.dat|title=Severe Tropical Cyclone Taliah Best Track|work=Joint Typhoon Warning Center|publisher=National Oceanic and Atmospheric Administration|access-date=12 February 2025}}</ref>

Taliah then continued on its path while varying in intensity between moderate and strong tropical storm before becoming a [[post-tropical cyclone]] on 18 February near 31°S latitude over increasingly cooler waters and showing very sporadic storm activity far from the center.

[[Météo-France]] started monitoring what would become Garance on 24 February. It subsequently received the name Garance, and was upgraded to a Moderate Tropical Storm on 25 February. From 26 to 27 February, Garance rapidly intensified into an Intense Tropical Cyclone. The purple alert was issued in Reunion on 28 February, as the cyclone approached.<ref>{{Cite web|url=https://www.france24.com/en/asia-pacific/20250228-cyclone-garance-puts-mauritius-la-reunion-on-high-alert |title=La Reunion island under 'purple alert' as Cyclone Garance approaches |access-date=28 February 2025 |website=France 24|date=28 February 2025 }}</ref> On 28 February, Intense Tropical Cyclone Garance made landfall at 10:00 RET in the morning near [[Sainte-Suzanne, Réunion|Sainte-Suzanne]], in the north of [[Réunion]] at Tropical Cyclone intensity.

[[Météo-France]] began monitoring an area of potential development in the southern [[Mozambique Channel]] on 24 February. Unlike Garance, which organised quickly, this system was much larger and more disorganised, requiring more time to develop. Several days before its formation, the system that would become Tropical Cyclone Honde was already bringing heavy and disruptive rainfall to southern [[Mozambique]] and, particularly, [[Madagascar]]. Météo-France officially upgraded Honde to a Moderate Tropical Storm on 26 February. Subsequently, it gradually strengthened to a Severe Tropical Storm the following day, before reaching Tropical Cyclone stage on 28 February, when it made its closest approach to Madagascar.

Honde caused severe damage in Madagascar. 43,200 people were affected, mainly in the Andrefana and Menabe regions. 7,200 homes were damaged and 1,900 homes were destroyed from strong winds and flooding. Three people were killed and 69 were injured during the storm.<ref>{{Cite web |date=6 March 2025 |title=Tropical Cyclone Honde - Feb 2025 {{!}} ReliefWeb |url=https://reliefweb.int/disaster/tc-2025-000025-mdg |access-date=9 March 2025 |website=reliefweb.int |language=en}}</ref>

Honde weakened into a tropical storm after passing Madagascar. Before turning extratropical, Honde briefly strengthened into a severe tropical storm on 5 March in the Southern Indian Ocean.

[[Météo-France]] began monitoring a disturbance south of the [[Chagos Islands]] on 6 March. It got upgraded to a depression a day later. It was then upgraded to a Moderate Tropical Storm on 8 March, where it got the name Jude. The tropical cyclone made landfall in Cabaceira, [[Mozambique]] as a Category 1 at 10 March.

In the municipality of [[Nacala-Porto]], six fatalities were recorded.<ref>{{Cite web |title=Mozambique: Tropical storm leaves fatalities and trail of destruction in Nampula |url=https://clubofmozambique.com/news/mozambique-tropical-storm-leaves-fatalities-and-trail-of-destruction-in-nampula-277563/ |access-date=11 March 2025 |website=Mozambique |language=en-US}}</ref> Overall, the cyclone caused 16 fatalities in Mozambique,<ref name=death-Jude-Mozambique>{{Cite web |last=Presse |first=AFP-Agence France |title=Mozambique Cyclone Death Toll Rises To 16 |url=https://www.barrons.com/articles/mozambique-cyclone-death-toll-rises-to-16-0ea12132 |access-date=15 March 2025 |website=barrons |language=en-us}}</ref> 2 in Madagascar,<ref name=death-Jude-Madagascar>{{cite web |language=en |url=https://reliefweb.int/report/madagascar/southern-africa-tropical-cyclone-jude-flash-update-no-1-11-march-2025 |title=Southern Africa: Tropical Cyclone Jude Flash Update No. 1 (as of 11 March 2025) |author=[[OCHA]] |date=11 March 2025 |publisher=ReliefWeb |access-date=11 March 2025}}</ref><ref name=OCHA-3-Jude>{{cite web |language=en |url=https://reliefweb.int/report/madagascar/southern-africa-tropical-storm-jude-flash-update-no-2-18-march-2025 |title=Southern Africa: Tropical Storm Jude Flash Update No. 2 (as of 18 March 2025) |author=[[OCHA]] |date=18 March 2025 |publisher=ReliefWeb |access-date=18 March 2025}}</ref> and 3 in Malawi.<ref name=death-Malawi-Jude>{{cite news |language=en |author1=Jamal Jamal |title=Tropical Cyclone Jude kills 9 people in Mozambique, Malawi |agency=[[Anadolu Agency]] |date= 14 March 2025 |url=https://www.aa.com.tr/en/asia-pacific/tropical-cyclone-jude-kills-9-people-in-mozambique-malawi/3509203 |access-date=15 March 2025

Meteo France started monitoring this system in the extreme eastern reaches of the basin on 8 March. It was upgraded to Moderate Tropical Storm Ivone the same day.

Ivone sustained its strength for a few days, as a tropical storm before dissipating on 11 March.

=== Intense Tropical Cyclone Kanto-Courtney ===

}}

On 29 March, Severe Tropical Cyclone Courtney entered from the Australian region. The system intensified further to a 140 mph (220 km/h) cyclone with a minimum central pressure of 929 according to Meteo France shortly after its arrival in the basin. Later that day, it started to show signs of weakening due to cooler sea surface temperatures. The Dvorak analysis carried out by the RSMC initially gave winds at 140 mph. The best track has therefore been revised slightly downwards to peaking at 125 mph instead.  Courtney turned into a post-tropical cyclone due to nearby dry air, wind shear, and cooler water while traversing through the Indian Ocean. The remnants of Courtney then travelled between Australia and Antarctica. There were no reports of damages.

Meteo France began monitoring an extratropical system hundreds of miles south of [[Madagascar]]. On the evening of 20 April, the system transitioned into a subtropical storm, thus receiving the name Kanto by Madagascar Meteorological services.<ref>http://metservice.intnet.mu/synoptic-chart.php</ref>

Kanto was the first subtropical system to develop in the region since Subtropical Depression Issa during the 2021–22 season. It was also the first to be designated a "subtropical storm" by Meteo France, which was introduced as a category for subtropical cyclones with maximum sustained winds above {{convert|65|km/h|mph|abbr=on}} beginning with the 2024–25 season.<ref>{{cite report|title=Regional Association I — Tropical Cyclone Operational Plan for the South-West Indian Ocean|date=2023|access-date=21 April 2025|publisher=World Meteorological Organization|url=https://wmoomm.sharepoint.com/:b:/s/wmocpdb/EYlTpV0sKLFAjl1s8ktbVBgBLNG3v60mFBTQ9TXnOcZZUw?e=GfpWcm}}</ref>

== Storm names ==
{{Main|Tropical cyclone naming}}
Within the South-West Indian Ocean, tropical depressions and subtropical depressions that are judged to have 10-minute sustained windspeeds of 65 km/h (40 mph) by the [[Regional Specialized Meteorological Center]] on [[Réunion]] island, France (RSMC La Réunion) are usually assigned a name. However, it is the Sub-Regional Tropical Cyclone Advisory Centers in Mauritius and Madagascar who name the systems. The Sub-Regional Tropical Cyclone Advisory Center (Mauritius Meteorological Services) in Mauritius names a storm if it intensifies into a moderate tropical storm between [[55th meridian east|55°E]] and [[90th meridian east|90°E]]. If instead a cyclone intensifies into a moderate tropical storm between [[30th meridian east|30°E]] and [[55th meridian east|55°E]] then the Sub-Regional Tropical Cyclone Advisory Center (Meteo Madagascar) in Madagascar assigns the appropriate name to the storm. Storm names are taken from three pre-determined lists of names, which rotate on a triennial basis, with any names that have been used automatically removed. New names this season are: Ancha, Bheki, Chido, Dikeledi, Elvis, Faida, Garance, Honde, Ivone, Jude, Kanto and Lira. They replaced Ana, Batsirai, Cliff, Dumako, Emnati, Fezile, Gombe, Halima, Issa, Jasmine and Karim during the [[2021–22 South-West Indian Ocean cyclone season|2021–22 season]], and also Letlama, which was not used, but the reason for its removal is unknown.<ref name="SWIO TCOP">{{cite report|author=RA I Tropical Cyclone Committee |publisher=World Meteorological Organization |title=Tropical Cyclone Operational Plan for the South-West Indian Ocean|year=2023|format=PDF |url=https://community.wmo.int/en/tropical-cyclone-operational-plans|archive-url=https://web.archive.org/web/20240702081536/https://www.theedkins.co.uk/storms/RAI_TCC-25_OperationalPlan_WMO-Nr1178_EN.pdf|archive-date=2 July 2024}}</ref>

Among them, Errol (third image in the second row) is the most intense with a minimum central pressure of 919 hPa.]]
In 2025, tropical cyclones will form in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones will be named by various weather agencies when they attain [[maximum sustained winds]] of {{convert|35|knots|km/h mph|round=5}}. The strongest system this year so far is [[2024–25 Australian region cyclone season#Severe Tropical Cyclone Errol|Cyclone Errol]], which attained a minimum barometric pressure of 919 hPa (27.26 inHg), [[Cyclone Jude]] is the deadliest system this year so far, causing at least 21 deaths in south-east Africa. [[Cyclone Alfred (2025)|Cyclone Alfred]] is the costliest system this year so far at $759 million in damage. The [[accumulated cyclone energy]] (ACE) index for the year (seven basins combined) so far, as calculated by Colorado State University (CSU), is 213.1 units overall.<ref>https://tropical.atmos.colostate.edu/Realtime/</ref>

Tropical cyclones are primarily monitored by ten warning centers around the world, which are designated as a [[Regional Specialized Meteorological Center]] (RSMC) or a [[Tropical Cyclone Warning Center]] (TCWC) by the [[World Meteorological Organization]] (WMO). These centers are: [[National Hurricane Center]] (NHC), [[Central Pacific Hurricane Center]] (CPHC), [[Japan Meteorological Agency]] (JMA), [[Indian Meteorological Department]] (IMD), [[Météo-France]] (MFR), Indonesia's [[Meteorology, Climatology, and Geophysical Agency]] (BMKG), Australian [[Bureau of Meteorology]] (BoM), Papua New Guinea's National Weather Service (PNGNWS), [[Fiji Meteorological Service]] (FMS), and New Zealand's [[MetService]]. Unofficial, but still notable, warning centers include the [[Philippine Atmospheric, Geophysical and Astronomical Services Administration]] (PAGASA; albeit official within the Philippines), the United States's [[Joint Typhoon Warning Center]] (JTWC), and the [[Brazilian Navy Hydrographic Center]].

In January, the [[Intertropical Convergence Zone]] (ITCZ), which allows for the formation of [[tropical wave]]s, is located in the [[Southern Hemisphere]], remaining there until May.<ref name="ITCZ">{{cite book|last=Longshore|first=David|title=Encyclopedia of Hurricanes, Typhoons, and Cyclones, New Edition|url=https://books.google.com/books?id=8kXwskQHBLoC&pg=PA115|year=2009|publisher=Infobase Publishing|isbn=978-1-4381-1879-6|page=333}}</ref> This limits [[Northern Hemisphere]] cyclone formation to comparatively rare non-tropical sources.<ref name=nontrop>{{cite web|url=http://ams.allenpress.com/perlserv/?request=get-abstract&doi=10.1175/1520-0493(1979)107%3C0812:NCSANE%3E2.0.CO;2|title=Northeasterly Cold Surges and Near-Equatorial Disturbances over the Winter MONEX Area during December 1974.

In the [[Southern Hemisphere]] basins, January, at the height of the [[austral summer]], is the most active month by cumulative number of storms since records began. Of the four Northern Hemisphere basins, none is very active in January, as the month is during the winter, but the most active basin is the Western Pacific, which occasionally sees weak tropical storms form during the month.<ref name="BOM database" /> January was unusually active, with twelve systems forming and seven storms getting named.

The month started off in the South-West Indian Ocean with [[Cyclone Dikeledi]], which intensified into a major cyclone before it made two landfalls at [[Antsiranana|Antsiranana, Madagascar]] and [[Nampula Province|Nampula Province, Mozambique]], [[Cyclone Elvis]] and [[Cyclone Faida]] also formed but was downgraded into a depression by MFR in post-storm analysis. Meanwhile, short-lived [[Cyclone Pita (2025)|Cyclone Pita]] formed on January 6, affecting some islands in the South Pacific basin. Weeks later, in the Australian basin, [[Cyclone Sean (2025)|Cyclone Sean]] developed on January 17. Sean rapidly intensified into a Category 3-tropical cyclone, marking it the second major tropical cyclone of the year after Dikeledi. [[Cyclone Taliah]] and [[Cyclone Vince (2025)|Cyclone Vince]] formed as well, with the latter rapidly intensifying into a Very Intense Tropical Cyclone in the South-West Indian Ocean, making it the strongest cyclone this month.

===February===
[[File:Zelia 2025-02-13 0000Z.jpg|thumb|[[Cyclone Zelia (2025)|Cyclone Zelia]]]]
February was extremely active. It was the most active month, and one of the third-most active months in any given year on record, with twelve systems forming and seven storms getting named. A total of seven tropical cyclones reached Category 3 strength or higher, the highest number since records began in [[Tropical cyclones in 2003|2003]].

Historically, February is normally similar to January in terms of activity, with most formations being effectively restricted to the Southern Hemisphere (with the exception of the rare Western Pacific disturbance this year). The month also tends to see more strong tropical cyclones forming compared to January, despite seeing marginally fewer overall storms, due to the [[monsoon]] being at its height in the Southern Hemisphere.<ref name="BOM database" /> In the Northern Hemisphere, February is the least active month, with no [[Pacific hurricane|Eastern or Central Pacific tropical cyclone]]s{{EPAC hurricane best track}} and [[1952 Groundhog Day tropical storm|only one]] Atlantic tropical cyclone having ever formed in the month. Even in the Western Pacific, February activity is low: in 2025, the month never saw a typhoon-strength storm, the first being [[Typhoon Higos (2015)|Typhoon Higos]] in 2015.

The month started off active with five systems forming in January and then persisting into February: Faida, 13U, Vince, Taliah, and 05F. [[Cyclone Zelia (2025)|Cyclone Zelia]] formed on February 7 near the [[Kimberley region]], and rapidly intensified into a Category 5 severe tropical cyclone six days later; it then made landfall near [[De Grey, Western Australia|De Grey]] in [[Australia]] as a Category 4 tropical cyclone.<ref>{{cite news|last=Yoon|first=John|url=https://www.nytimes.com/2025/02/14/world/australia/tropical-cyclone-zelia.html|title=Tropical Cyclone Zelia Makes Landfall in Northwest Australia|publisher=The New York Times|date=February 14, 2025|access-date=February 15, 2025|archive-url=https://web.archive.org/web/20250215040927/https://www.nytimes.com/2025/02/14/world/australia/tropical-cyclone-zelia.html|archive-date=February 15, 2025|url-status=live}}</ref> Two tropical cyclones formed in the Australian region on February 20 – Bianca and Alfred – while in the South-West Indian Ocean, two cyclones also formed near Madagascar: Garance and Honde. The former eventually became an intense tropical cyclone on February 27 before making landfall in the northern part of [[Réunion]] the next day as a slightly weaker tropical cyclone.

[[File:Courtney 2025-03-29 1000Z.jpg|thumb|[[Cyclone Courtney (2025)|Cyclone Courtney]]]]
During March, activity tends to be lower than in preceding months. In the Southern Hemisphere, the peak of the season has normally already passed, and the monsoon has begun to weaken, decreasing cyclonic activity, however, the month often sees more intense tropical cyclones than January or February.<ref name="BOM database" /> Meanwhile, in the Northern Hemisphere basins, sea surface temperatures are still far too low to normally support tropical cyclogenesis. The exception is the Western Pacific, which usually sees its first storm, often a weak depression, at some point between January and April.

March was inactive, featuring five storms, of which four have been named. [[Cyclone Alfred (2025)|Cyclone Alfred]], [[Cyclone Honde|Honde]], and [[Cyclone Garance|Garance]] formed in February and persisted into March. The strongest storm of the month is [[2024–25 Australian region cyclone season#Severe Tropical Cyclone Courtney|Cyclone Courtney]]. At the start of the month, [[Cyclone Jude]] had caused 21 deaths in Southeastern Africa.

===April===
[[File:Errol 2025-04-16 0520Z.jpg|thumb|[[Cyclone Errol (2025)|Cyclone Errol]]]]
The factors that begin to inhibit Southern Hemisphere cyclone formation in March are even more pronounced in April, with the average number of storms formed being hardly half that of March.<ref name="BOM database" /><ref name="apr" /> However, even this limited activity exceeds the activity in the Northern Hemisphere, which is rare, with the exception of the Western Pacific basin. All [[Pacific typhoon season]]s between [[1998 Pacific typhoon season|1998]] and [[2016 Pacific typhoon season|2016]] saw activity between January and April, although many of these seasons saw only weak tropical depressions.<ref name="JMA BT" /> By contrast, only two [[Atlantic hurricane season]]s during those years saw tropical cyclone formation during that period.{{Atlantic hurricane best track}} With the combination of the decreasing temperatures in the Southern Hemisphere and the still-low temperatures in the Northern Hemisphere, April and May tend to be the least active months worldwide for tropical cyclone formation.<ref name="apr" />

So far in April, three storms have formed, two being named. The month started off in the Australian basin with the formation of [[Cyclone Errol (2025)|Cyclone Errol]], which would later become the first Category 5 equivalent cyclone of the year, and is the strongest cyclone this month so far. Following that was the formation of [[2024–25 Australian region cyclone season#Tropical Low 30U|Tropical Low 30U]]. In the southern pacific, [[Cyclone Tam (2025)|Cyclone Tam]] formed and breifly impacted [[Vanuatu]].

Among them, Vince (third image in the first row) is the most intense with a minimum central pressure of 923 hPa.]]
In 2025, tropical cyclones will form in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones will be named by various weather agencies when they attain [[maximum sustained winds]] of {{convert|35|knots|km/h mph|round=5}}. The strongest system this year so far is [[Cyclone Vince (2025)|Cyclone Vince]], which attained a minimum barometric pressure of 923 hPa (27.26 inHg), [[Cyclone Jude]] is the deadliest system this year so far, causing at least 21 deaths in south-east Africa. [[Cyclone Alfred (2025)|Cyclone Alfred]] is the costliest system this year so far at $759 million in damage. The [[accumulated cyclone energy]] (ACE) index for the year (seven basins combined) so far, as calculated by Colorado State University (CSU), is 200.9 units overall.<ref>https://tropical.atmos.colostate.edu/Realtime/</ref>

Tropical cyclones are primarily monitored by ten warning centers around the world, which are designated as a [[Regional Specialized Meteorological Center]] (RSMC) or a [[Tropical Cyclone Warning Center]] ((TCWC) by the [[World Meteorological Organization]] (WMO). These centers are: [[National Hurricane Center]] (NHC), [[Central Pacific Hurricane Center]] (CPHC), [[Japan Meteorological Agency]] (JMA), [[Indian Meteorological Department]] (IMD), [[Météo-France]] (MFR), Indonesia's [[Meteorology, Climatology, and Geophysical Agency]] (BMKG), Australian [[Bureau of Meteorology]] (BoM), Papua New Guinea's National Weather Service (PNGNWS), [[Fiji Meteorological Service]] (FMS), and New Zealand's [[MetService]]. Unofficial, but still notable, warning centers include the [[Philippine Atmospheric, Geophysical and Astronomical Services Administration]] (PAGASA; albeit official within the Philippines), the United States's [[Joint Typhoon Warning Center]] (JTWC), and the [[Brazilian Navy Hydrographic Center]].

In January, the [[Intertropical Convergence Zone]] (ITCZ), which allows for the formation of [[tropical wave]]s, is located in the [[Southern Hemisphere]], remaining there until May.<ref name="ITCZ">{{cite book|last=Longshore|first=David|title=Encyclopedia of Hurricanes, Typhoons, and Cyclones, New Edition|url=https://books.google.com/books?id=8kXwskQHBLoC&pg=PA115|year=2009|publisher=Infobase Publishing|isbn=978-1-4381-1879-6|page=333}}</ref> This limits [[Northern Hemisphere]] cyclone formation to comparatively rare non-tropical sources.<ref name=nontrop>{{cite web|url=http://ams.allenpress.com/perlserv/?request=get-abstract&doi=10.1175/1520-0493(1979)107%3C0812:NCSANE%3E2.0.CO;2|title=Northeasterly Cold Surges and Near-Equatorial Disturbances over the Winter MONEX Area during December 1974.

In the [[Southern Hemisphere]] basins, January, at the height of the [[austral summer]], is the most active month by cumulative number of storms since records began. Of the four Northern Hemisphere basins, none is very active in January, as the month is during the winter, but the most active basin is the Western Pacific, which occasionally sees weak tropical storms form during the month.<ref name="BOM database" /> January was unusually active, with twelve systems forming and seven storms getting named.

The month started off in the South-West Indian Ocean with [[Cyclone Dikeledi]], which intensified into a major cyclone before it made two landfalls at [[Antsiranana|Antsiranana, Madagascar]] and [[Nampula Province|Nampula Province, Mozambique]], [[Cyclone Elvis]] and [[Cyclone Faida]] also formed but was downgraded into a depression by MFR in post-storm analysis. Meanwhile, short-lived [[Cyclone Pita (2025)|Cyclone Pita]] formed on January 6, affecting some islands in the South Pacific basin. Weeks later, in the Australian basin, [[Cyclone Sean (2025)|Cyclone Sean]] developed on January 17. Sean rapidly intensified into a Category 3-tropical cyclone, marking it the second major tropical cyclone of the year after Dikeledi. [[Cyclone Taliah]] and [[Cyclone Vince (2025)|Cyclone Vince]] formed as well, with the latter rapidly intensifying into a Very Intense Tropical Cyclone in the South-West Indian Ocean, making it the strongest cyclone this month.

===February===
[[File:Zelia 2025-02-13 0000Z.jpg|thumb|[[Cyclone Zelia (2025)|Cyclone Zelia]]]]
February was extremely active. It was the most active month, and one of the third-most active months in any given year on record, with twelve systems forming and seven storms getting named. A total of seven tropical cyclones reached Category 3 strength or higher, the highest number since records began in [[Tropical cyclones in 2003|2003]].

Historically, February is normally similar to January in terms of activity, with most formations being effectively restricted to the Southern Hemisphere (with the exception of the rare Western Pacific disturbance this year). The month also tends to see more strong tropical cyclones forming compared to January, despite seeing marginally fewer overall storms, due to the [[monsoon]] being at its height in the Southern Hemisphere.<ref name="BOM database" /> In the Northern Hemisphere, February is the least active month, with no [[Pacific hurricane|Eastern or Central Pacific tropical cyclone]]s{{EPAC hurricane best track}} and [[1952 Groundhog Day tropical storm|only one]] Atlantic tropical cyclone having ever formed in the month. Even in the Western Pacific, February activity is low: in 2025, the month never saw a typhoon-strength storm, the first being [[Typhoon Higos (2015)|Typhoon Higos]] in 2015.

The month started off active with five systems forming in January and then persisting into February: Faida, 13U, Vince, Taliah, and 05F. [[Cyclone Zelia (2025)|Cyclone Zelia]] formed on February 7 near the [[Kimberley region]], and rapidly intensified into a Category 5 severe tropical cyclone six days later; it then made landfall near [[De Grey, Western Australia|De Grey]] in [[Australia]] as a Category 4 tropical cyclone.<ref>{{cite news|last=Yoon|first=John|url=https://www.nytimes.com/2025/02/14/world/australia/tropical-cyclone-zelia.html|title=Tropical Cyclone Zelia Makes Landfall in Northwest Australia|publisher=The New York Times|date=February 14, 2025|access-date=February 15, 2025|archive-url=https://web.archive.org/web/20250215040927/https://www.nytimes.com/2025/02/14/world/australia/tropical-cyclone-zelia.html|archive-date=February 15, 2025|url-status=live}}</ref> Two tropical cyclones formed in the Australian region on February 20 – Bianca and Alfred – while in the South-West Indian Ocean, two cyclones also formed near Madagascar: Garance and Honde. The former eventually became an intense tropical cyclone on February 27 before making landfall in the northern part of [[Réunion]] the next day as a slightly weaker tropical cyclone.

=== March ===
[[File:Courtney 2025-03-29 1000Z.jpg|thumb|[[Cyclone Courtney (2025)|Cyclone Courtney]]]]
During March, activity tends to be lower than in preceding months. In the Southern Hemisphere, the peak of the season has normally already passed, and the monsoon has begun to weaken, decreasing cyclonic activity, however, the month often sees more intense tropical cyclones than January or February.<ref name="BOM database" /> Meanwhile, in the Northern Hemisphere basins, sea surface temperatures are still far too low to normally support tropical cyclogenesis. The exception is the Western Pacific, which usually sees its first storm, often a weak depression, at some point between January and April.

March was inactive, featuring five storms, of which four have been named. [[Cyclone Alfred (2025)|Cyclone Alfred]], [[Cyclone Honde|Honde]], and [[Cyclone Garance|Garance]] formed in February and persisted into March. The strongest storm of the month is [[2024–25 Australian region cyclone season#Severe Tropical Cyclone Courtney|Cyclone Courtney]]. At the start of the month, [[Cyclone Jude]] had caused 21 deaths in Southeastern Africa.

===April===
[[File:Errol 2025-04-15 2350Z.jpg|thumb|[[Cyclone Errol (2025)|Cyclone Errol]]]]
The factors that begin to inhibit Southern Hemisphere cyclone formation in March are even more pronounced in April, with the average number of storms formed being hardly half that of March.<ref name="BOM database" /><ref name="apr" /> However, even this limited activity exceeds the activity in the Northern Hemisphere, which is rare, with the exception of the Western Pacific basin. All [[Pacific typhoon season]]s between [[1998 Pacific typhoon season|1998]] and [[2016 Pacific typhoon season|2016]] saw activity between January and April, although many of these seasons saw only weak tropical depressions.<ref name="JMA BT" /> By contrast, only two [[Atlantic hurricane season]]s during those years saw tropical cyclone formation during that period.{{Atlantic hurricane best track}} With the combination of the decreasing temperatures in the Southern Hemisphere and the still-low temperatures in the Northern Hemisphere, April and May tend to be the least active months worldwide for tropical cyclone formation.<ref name="apr" />

Among them, Vince (third image in the first row) is the most intense with a minimum central pressure of 923 hPa.]]
In 2025, tropical cyclones will form in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones will be named by various weather agencies when they attain [[maximum sustained winds]] of {{convert|35|knots|km/h mph|round=5}}. The strongest system this year so far is [[Cyclone Vince (2025)|Cyclone Vince]], which attained a minimum barometric pressure of 923 hPa (27.26 inHg), [[Cyclone Jude]] is the deadliest system this year so far, causing at least 21 deaths in south-east Africa. [[Cyclone Alfred (2025)|Cyclone Alfred]] is the costliest system this year so far at $759 million in damage. The [[accumulated cyclone energy]] (ACE) index for the year (seven basins combined) so far, as calculated by Colorado State University (CSU), is 200.9 units overall.<ref>https://tropical.atmos.colostate.edu/Realtime/</ref>

Tropical cyclones are primarily monitored by ten warning centers around the world, which are designated as a [[Regional Specialized Meteorological Center]] (RSMC) or a [[Tropical Cyclone Warning Center]] ((TCWC) by the [[World Meteorological Organization]] (WMO). These centers are: [[National Hurricane Center]] (NHC), [[Central Pacific Hurricane Center]] (CPHC), [[Japan Meteorological Agency]] (JMA), [[Indian Meteorological Department]] (IMD), [[Météo-France]] (MFR), Indonesia's [[Meteorology, Climatology, and Geophysical Agency]] (BMKG), Australian [[Bureau of Meteorology]] (BoM), Papua New Guinea's National Weather Service (PNGNWS), [[Fiji Meteorological Service]] (FMS), and New Zealand's [[MetService]]. Unofficial, but still notable, warning centers include the [[Philippine Atmospheric, Geophysical and Astronomical Services Administration]] (PAGASA; albeit official within the Philippines), the United States's [[Joint Typhoon Warning Center]] (JTWC), and the [[Brazilian Navy Hydrographic Center]].

In January, the [[Intertropical Convergence Zone]] (ITCZ), which allows for the formation of [[tropical wave]]s, is located in the [[Southern Hemisphere]], remaining there until May.<ref name="ITCZ">{{cite book|last=Longshore|first=David|title=Encyclopedia of Hurricanes, Typhoons, and Cyclones, New Edition|url=https://books.google.com/books?id=8kXwskQHBLoC&pg=PA115|year=2009|publisher=Infobase Publishing|isbn=978-1-4381-1879-6|page=333}}</ref> This limits [[Northern Hemisphere]] cyclone formation to comparatively rare non-tropical sources.<ref name=nontrop>{{cite web|url=http://ams.allenpress.com/perlserv/?request=get-abstract&doi=10.1175/1520-0493(1979)107%3C0812:NCSANE%3E2.0.CO;2|title=Northeasterly Cold Surges and Near-Equatorial Disturbances over the Winter MONEX Area during December 1974.

In the [[Southern Hemisphere]] basins, January, at the height of the [[austral summer]], is the most active month by cumulative number of storms since records began. Of the four Northern Hemisphere basins, none is very active in January, as the month is during the winter, but the most active basin is the Western Pacific, which occasionally sees weak tropical storms form during the month.<ref name="BOM database" /> January was unusually active, with twelve systems forming and seven storms getting named.

The month started off in the South-West Indian Ocean with [[Cyclone Dikeledi]], which intensified into a major cyclone before it made two landfalls at [[Antsiranana|Antsiranana, Madagascar]] and [[Nampula Province|Nampula Province, Mozambique]], [[Cyclone Elvis]] and [[Cyclone Faida]] also formed but was downgraded into a depression by MFR in post-storm analysis. Meanwhile, short-lived [[Cyclone Pita (2025)|Cyclone Pita]] formed on January 6, affecting some islands in the South Pacific basin. Weeks later, in the Australian basin, [[Cyclone Sean (2025)|Cyclone Sean]] developed on January 17. Sean rapidly intensified into a Category 3-tropical cyclone, marking it the second major tropical cyclone of the year after Dikeledi. [[Cyclone Taliah]] and [[Cyclone Vince (2025)|Cyclone Vince]] formed as well, with the latter rapidly intensifying into a Very Intense Tropical Cyclone in the South-West Indian Ocean, making it the strongest cyclone this month.

===February===
[[File:Zelia 2025-02-13 0000Z.jpg|thumb|[[Cyclone Zelia (2025)|Cyclone Zelia]]]]
February was extremely active. It was the most active month, and one of the third-most active months in any given year on record, with twelve systems forming and seven storms getting named. A total of seven tropical cyclones reached Category 3 strength or higher, the highest number since records began in [[Tropical cyclones in 2003|2003]].

Historically, February is normally similar to January in terms of activity, with most formations being effectively restricted to the Southern Hemisphere (with the exception of the rare Western Pacific disturbance this year). The month also tends to see more strong tropical cyclones forming compared to January, despite seeing marginally fewer overall storms, due to the [[monsoon]] being at its height in the Southern Hemisphere.<ref name="BOM database" /> In the Northern Hemisphere, February is the least active month, with no [[Pacific hurricane|Eastern or Central Pacific tropical cyclone]]s{{EPAC hurricane best track}} and [[1952 Groundhog Day tropical storm|only one]] Atlantic tropical cyclone having ever formed in the month. Even in the Western Pacific, February activity is low: in 2025, the month never saw a typhoon-strength storm, the first being [[Typhoon Higos (2015)|Typhoon Higos]] in 2015.

The month started off active with five systems forming in January and then persisting into February: Faida, 13U, Vince, Taliah, and 05F. [[Cyclone Zelia (2025)|Cyclone Zelia]] formed on February 7 near the [[Kimberley region]], and rapidly intensified into a Category 5 severe tropical cyclone six days later; it then made landfall near [[De Grey, Western Australia|De Grey]] in [[Australia]] as a Category 4 tropical cyclone.<ref>{{cite news|last=Yoon|first=John|url=https://www.nytimes.com/2025/02/14/world/australia/tropical-cyclone-zelia.html|title=Tropical Cyclone Zelia Makes Landfall in Northwest Australia|publisher=The New York Times|date=February 14, 2025|access-date=February 15, 2025|archive-url=https://web.archive.org/web/20250215040927/https://www.nytimes.com/2025/02/14/world/australia/tropical-cyclone-zelia.html|archive-date=February 15, 2025|url-status=live}}</ref> Two tropical cyclones formed in the Australian region on February 20 – Bianca and Alfred – while in the South-West Indian Ocean, two cyclones also formed near Madagascar: Garance and Honde. The former eventually became an intense tropical cyclone on February 27 before making landfall in the northern part of [[Réunion]] the next day as a slightly weaker tropical cyclone.

=== March ===
[[File:Courtney 2025-03-29 1000Z.jpg|thumb|[[Cyclone Courtney (2025)|Cyclone Courtney]]]]
During March, activity tends to be lower than in preceding months. In the Southern Hemisphere, the peak of the season has normally already passed, and the monsoon has begun to weaken, decreasing cyclonic activity, however, the month often sees more intense tropical cyclones than January or February.<ref name="BOM database" /> Meanwhile, in the Northern Hemisphere basins, sea surface temperatures are still far too low to normally support tropical cyclogenesis. The exception is the Western Pacific, which usually sees its first storm, often a weak depression, at some point between January and April.

March was inactive, featuring five storms, of which four have been named. [[Cyclone Alfred (2025)|Cyclone Alfred]], [[Cyclone Honde|Honde]], and [[Cyclone Garance|Garance]] formed in February and persisted into March. The strongest storm of the month is [[2024–25 Australian region cyclone season#Severe Tropical Cyclone Courtney|Cyclone Courtney]]. At the start of the month, [[Cyclone Jude]] had caused 21 deaths in Southeastern Africa.

The factors that begin to inhibit Southern Hemisphere cyclone formation in March are even more pronounced in April, with the average number of storms formed being hardly half that of March.<ref name="BOM database" /><ref name="apr" /> However, even this limited activity exceeds the activity in the Northern Hemisphere, which is rare, with the exception of the Western Pacific basin. All [[Pacific typhoon season]]s between [[1998 Pacific typhoon season|1998]] and [[2016 Pacific typhoon season|2016]] saw activity between January and April, although many of these seasons saw only weak tropical depressions.<ref name="JMA BT" /> By contrast, only two [[Atlantic hurricane season]]s during those years saw tropical cyclone formation during that period.{{Atlantic hurricane best track}} With the combination of the decreasing temperatures in the Southern Hemisphere and the still-low temperatures in the Northern Hemisphere, April and May tend to be the least active months worldwide for tropical cyclone formation.<ref name="apr" />

Among them, Vince (third image in the first row) is the most intense with a minimum central pressure of 923 hPa.]]
In 2025, tropical cyclones will form in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones will be named by various weather agencies when they attain [[maximum sustained winds]] of {{convert|35|knots|km/h mph|round=5}}. The strongest system this year so far is [[Cyclone Vince (2025)|Cyclone Vince]], which attained a minimum barometric pressure of 923 hPa (27.26 inHg), [[Cyclone Jude]] is the deadliest system this year so far, causing at least 21 deaths in south-east Africa. [[Cyclone Alfred (2025)|Cyclone Alfred]] is the costliest system this year so far at $759 million in damage. The [[accumulated cyclone energy]] (ACE) index for the year (seven basins combined) so far, as calculated by Colorado State University (CSU), is 200.9 units overall.<ref>https://tropical.atmos.colostate.edu/Realtime/</ref>

Tropical cyclones are primarily monitored by ten warning centers around the world, which are designated as a [[Regional Specialized Meteorological Center]] (RSMC) or a [[Tropical Cyclone Warning Center]] ((TCWC) by the [[World Meteorological Organization]] (WMO). These centers are: [[National Hurricane Center]] (NHC), [[Central Pacific Hurricane Center]] (CPHC), [[Japan Meteorological Agency]] (JMA), [[Indian Meteorological Department]] (IMD), [[Météo-France]] (MFR), Indonesia's [[Meteorology, Climatology, and Geophysical Agency]] (BMKG), Australian [[Bureau of Meteorology]] (BoM), Papua New Guinea's National Weather Service (PNGNWS), [[Fiji Meteorological Service]] (FMS), and New Zealand's [[MetService]]. Unofficial, but still notable, warning centers include the [[Philippine Atmospheric, Geophysical and Astronomical Services Administration]] (PAGASA; albeit official within the Philippines), the United States's [[Joint Typhoon Warning Center]] (JTWC), and the [[Brazilian Navy Hydrographic Center]].

In January, the [[Intertropical Convergence Zone]] (ITCZ), which allows for the formation of [[tropical wave]]s, is located in the [[Southern Hemisphere]], remaining there until May.<ref name="ITCZ">{{cite book|last=Longshore|first=David|title=Encyclopedia of Hurricanes, Typhoons, and Cyclones, New Edition|url=https://books.google.com/books?id=8kXwskQHBLoC&pg=PA115|year=2009|publisher=Infobase Publishing|isbn=978-1-4381-1879-6|page=333}}</ref> This limits [[Northern Hemisphere]] cyclone formation to comparatively rare non-tropical sources.<ref name=nontrop>{{cite web|url=http://ams.allenpress.com/perlserv/?request=get-abstract&doi=10.1175/1520-0493(1979)107%3C0812:NCSANE%3E2.0.CO;2|title=Northeasterly Cold Surges and Near-Equatorial Disturbances over the Winter MONEX Area during December 1974.

In the [[Southern Hemisphere]] basins, January, at the height of the [[austral summer]], is the most active month by cumulative number of storms since records began. Of the four Northern Hemisphere basins, none is very active in January, as the month is during the winter, but the most active basin is the Western Pacific, which occasionally sees weak tropical storms form during the month.<ref name="BOM database" /> January was unusually active, with twelve systems forming and seven storms getting named.

The month started off in the South-West Indian Ocean with [[Cyclone Dikeledi]], which intensified into a major cyclone before it made two landfalls at [[Antsiranana|Antsiranana, Madagascar]] and [[Nampula Province|Nampula Province, Mozambique]], [[Cyclone Elvis]] and [[Cyclone Faida]] also formed but was downgraded into a depression by MFR in post-storm analysis. Meanwhile, short-lived [[Cyclone Pita (2025)|Cyclone Pita]] formed on January 6, affecting some islands in the South Pacific basin. Weeks later, in the Australian basin, [[Cyclone Sean (2025)|Cyclone Sean]] developed on January 17. Sean rapidly intensified into a Category 3-tropical cyclone, marking it the second major tropical cyclone of the year after Dikeledi. [[Cyclone Taliah]] and [[Cyclone Vince (2025)|Cyclone Vince]] formed as well, with the latter rapidly intensifying into a Very Intense Tropical Cyclone in the South-West Indian Ocean, making it the strongest cyclone this month.

===February===
[[File:Zelia 2025-02-13 0000Z.jpg|thumb|[[Cyclone Zelia (2025)|Cyclone Zelia]]]]
February was extremely active. It was the most active month, and one of the third-most active months in any given year on record, with twelve systems forming and seven storms getting named. A total of seven tropical cyclones reached Category 3 strength or higher, the highest number since records began in [[Tropical cyclones in 2003|2003]].

Historically, February is normally similar to January in terms of activity, with most formations being effectively restricted to the Southern Hemisphere (with the exception of the rare Western Pacific disturbance this year). The month also tends to see more strong tropical cyclones forming compared to January, despite seeing marginally fewer overall storms, due to the [[monsoon]] being at its height in the Southern Hemisphere.<ref name="BOM database" /> In the Northern Hemisphere, February is the least active month, with no [[Pacific hurricane|Eastern or Central Pacific tropical cyclone]]s{{EPAC hurricane best track}} and [[1952 Groundhog Day tropical storm|only one]] Atlantic tropical cyclone having ever formed in the month. Even in the Western Pacific, February activity is low: in 2025, the month never saw a typhoon-strength storm, the first being [[Typhoon Higos (2015)|Typhoon Higos]] in 2015.

The month started off active with five systems forming in January and then persisting into February: Faida, 13U, Vince, Taliah, and 05F. [[Cyclone Zelia (2025)|Cyclone Zelia]] formed on February 7 near the [[Kimberley region]], and rapidly intensified into a Category 5 severe tropical cyclone six days later; it then made landfall near [[De Grey, Western Australia|De Grey]] in [[Australia]] as a Category 4 tropical cyclone.<ref>{{cite news|last=Yoon|first=John|url=https://www.nytimes.com/2025/02/14/world/australia/tropical-cyclone-zelia.html|title=Tropical Cyclone Zelia Makes Landfall in Northwest Australia|publisher=The New York Times|date=February 14, 2025|access-date=February 15, 2025|archive-url=https://web.archive.org/web/20250215040927/https://www.nytimes.com/2025/02/14/world/australia/tropical-cyclone-zelia.html|archive-date=February 15, 2025|url-status=live}}</ref> Two tropical cyclones formed in the Australian region on February 20 – Bianca and Alfred – while in the South-West Indian Ocean, two cyclones also formed near Madagascar: Garance and Honde. The former eventually became an intense tropical cyclone on February 27 before making landfall in the northern part of [[Réunion]] the next day as a slightly weaker tropical cyclone.

=== March ===
[[File:Courtney 2025-03-29 1000Z.jpg|thumb|[[Cyclone Courtney (2025)|Cyclone Courtney]]]]
During March, activity tends to be lower than in preceding months. In the Southern Hemisphere, the peak of the season has normally already passed, and the monsoon has begun to weaken, decreasing cyclonic activity, however, the month often sees more intense tropical cyclones than January or February.<ref name="BOM database" /> Meanwhile, in the Northern Hemisphere basins, sea surface temperatures are still far too low to normally support tropical cyclogenesis. The exception is the Western Pacific, which usually sees its first storm, often a weak depression, at some point between January and April.

March was inactive, featuring five storms, of which four have been named. [[Cyclone Alfred (2025)|Cyclone Alfred]], [[Cyclone Honde|Honde]], and [[Cyclone Garance|Garance]] formed in February and persisted into March. The strongest storm of the month is [[2024–25 Australian region cyclone season#Severe Tropical Cyclone Courtney|Cyclone Courtney]]. At the start of the month, [[Cyclone Jude]] had caused 21 deaths in Southeastern Africa.

The factors that begin to inhibit Southern Hemisphere cyclone formation in March are even more pronounced in April, with the average number of storms formed being hardly half that of March.<ref name="BOM database" /><ref name="apr" /> However, even this limited activity exceeds the activity in the Northern Hemisphere, which is rare, with the exception of the Western Pacific basin. All [[Pacific typhoon season]]s between [[1998 Pacific typhoon season|1998]] and [[2016 Pacific typhoon season|2016]] saw activity between January and April, although many of these seasons saw only weak tropical depressions.<ref name="JMA BT" /> By contrast, only two [[Atlantic hurricane season]]s during those years saw tropical cyclone formation during that period.{{Atlantic hurricane best track}} With the combination of the decreasing temperatures in the Southern Hemisphere and the still-low temperatures in the Northern Hemisphere, April and May tend to be the least active months worldwide for tropical cyclone formation.<ref name="apr" />

During 2021, [[tropical cyclone]]s formed in seven major bodies of water, commonly known as [[tropical cyclone basins]]. Tropical cyclones will be assigned names by various weather agencies if they attain [[maximum sustained winds]] of {{convert|35|knots|km/h mph|round=5}}. During the year, 136 systems have formed and 94 were named, including one subtropical depression and excluding one system, which was unofficial. [[Cyclones Gulab and Shaheen|One storm]] was given two names by the same [[Regional Specialized Meteorological Centre|RSMC]]. The most intense storm of the year was [[Typhoon Surigae]], with maximum 10-minute sustained wind speeds of {{cvt|220|km/h|round=10}} and a minimum pressure of {{convert|895|hPa|inHg|sigfig=4|abbr=on|comma=off}}. The deadliest tropical cyclone was [[Typhoon Rai]], which caused 410 fatalities in the [[Philippines]] and 1 in [[Vietnam]], while the costliest was [[Hurricane Ida]], which caused an estimated $75.25 billion [[United States dollar|USD]] in damage after striking [[Louisiana]] and the [[Northeastern United States]].

Like last year, 2021 had an above average amount of tropical cyclones globally. The most active basin of the year was the [[2021 Pacific typhoon season|West Pacific]], which had another below average season, with only 23 named storms. The [[2021 Atlantic hurricane season|North Atlantic]] had another very active season, producing 21 named storms, while the [[2021 Pacific hurricane season|East Pacific]] featured average activity, with 19 named storms forming in the basin. The [[2023 North Indian Ocean cyclone season|North Indian]] basin was also average, featuring 5 named storms. The Southern Hemisphere featured relatively average activity, with Cyclones [[Cyclone Faraji|Faraji]] and [[Cyclone Niran|Niran]] both attaining [[Saffir–Simpson scale|Category 5]] intensity. The rest of the [[Saffir-Simpson scale|Category 5 tropical cyclones]] occurred in the West Pacific, totalling to six [[Saffir-Simpson scale|Category 5 tropical cyclones]] that formed during the year, tying [[Tropical cyclones in 2003|2003]]. However, the number of [[Saffir–Simpson scale|major tropical cyclones]] across the world was below average, with only 16 forming. The [[accumulated cyclone energy]] (ACE) index for 2021 (seven basins combined), as calculated by Colorado State University (CSU) was 621.1 units overall, which was below the 1991-2020 mean of 789.0 units globally.<ref>{{Cite web |[email protected] |title=Annual 2021 Tropical Cyclones Report {{!}} National Centers for Environmental Information (NCEI) |url=https://www.ncei.noaa.gov/access/monitoring/monthly-report/tropical-cyclones/202113 |access-date=2024-03-19 |website=www.ncei.noaa.gov |language=en}}</ref><ref>{{Cite web |title=Global Metrics of Tropical Cyclones |url=https://tropical.atmos.colostate.edu/Realtime/index.php?arch&loc=global}}</ref>

Tropical cyclones are primarily monitored by a group of ten warning centers, which have been designated as a [[Regional Specialized Meteorological Centre]] (RSMC) or a [[Tropical Cyclone Warning Center]] (TCWC) by the [[World Meteorological Organization]]. These are the United States [[National Hurricane Center]] (NHC) and [[Central Pacific Hurricane Center]], the [[Japan Meteorological Agency]] (JMA), the [[Indian Meteorological Department]] (IMD), [[Météo-France]] (MFR), Indonesia's [[Meteorology, Climatology, and Geophysical Agency|Badan Meteorologi, Klimatologi, dan Geofisika]], the Australian [[Bureau of Meteorology]] (BOM), Papua New Guinea's National Weather Service, the [[Fiji Meteorological Service]] (FMS) as well as New Zealand's [[MetService]]. Other notable warning centers include the [[Philippine Atmospheric, Geophysical, and Astronomical Services Administration]] (PAGASA), the United States [[Joint Typhoon Warning Center]] (JTWC), and the [[Brazilian Navy|Brazilian Navy Hydrographic Center (BNHC)]].

{{further|2021 Atlantic hurricane season}}
The 2021 Atlantic hurricane season officially ran from June 1 to November 30. A total of 21 tropical depressions formed, all of which reached at least tropical or subtropical intensity. The season ranks as the third-most active of all time in the Atlantic basin, behind only [[2005 Atlantic hurricane season|2005]] and [[2020 Atlantic hurricane season|2020]]. Consequently, the 2021 Atlantic hurricane season was the third on record to exhaust its [[Tropical cyclone naming|naming list]]. Nine of the systems lasted for two days or less, tied with [[2007 Atlantic hurricane season|2007]] for the most since the NHC began monitoring subtropical systems in [[1968 Atlantic hurricane season|1968]]. Although the season was highly active in terms of the number of named storms, seven of those tropical or subtropical systems intensified into a hurricane and four of those became a major hurricane, which is near-average and just slightly above-average, respectively. Nonetheless, 2021 marked the record sixth consecutive above-average season in the Atlantic.<ref name="Masters summary">{{cite web|last=Masters|first=Jeff|title=Top-10 weirdest things about the bonkers 2021 Atlantic hurricane season|date=November 30, 2021|url=https://yaleclimateconnections.org/2021/11/top-10-weirdest-things-about-the-bonkers-2021-atlantic-hurricane-season/|publisher=Yale Center for Environmental Communication|location=New Haven, Connecticut|access-date=May 27, 2022}}</ref> The ongoing warm [[Atlantic multidecadal oscillation]], which began in [[1995 Atlantic hurricane season|1995]], contributed to the season's high level of activity, as it led to above-average [[sea surface temperature]]s in the Atlantic basin. Other factors included the presence of a [[La Niña]] and abnormally heavy West African Monsoon precipitation.<ref name="noaa11/30">{{cite web|url=https://www.noaa.gov/news-release/active-2021-atlantic-hurricane-season-officially-ends|title=Active 2021 Atlantic hurricane season officially ends|date=November 30, 2021|publisher=National Oceanic and Atmospheric Administration|accessdate=May 28, 2022}}</ref>

Collectively, the tropical and subtropical systems of the 2021 Atlantic hurricane season caused 194 deaths and about $80.727 billion in damage,<ref>

On August 11, Fred formed in the eastern Caribbean, bringing impacts to the [[Greater Antilles|Greater]] and [[Lesser Antilles]], and the Southeastern United States. A few days later, [[Hurricane Grace|Grace]] formed and strengthened into the second hurricane and first major hurricane of the season, and brought impacts to the Greater Antilles and the [[Yucatán Peninsula]], before making landfall in the [[List of states of Mexico|Mexican state]] of [[Veracruz]]. A third tropical system, Henri, developed on August 16, near [[Bermuda]]. Henri meandered for several days before becoming the third hurricane of the season on August 21 and impacted New England, causing record flooding in some places. Towards the end of the month, Hurricane Ida formed, leaving major damage in western Cuba before rapidly intensifying into a Category 4 hurricane and making landfall in southeastern Louisiana at peak intensity, producing widespread, catastrophic damage. Its remnants then generated a [[Hurricane Ida tornado outbreak|deadly tornado outbreak]] and widespread, record-breaking flooding across the Northeastern United States. Two other tropical storms, Julian and Kate, also existed briefly during this time but remained at sea. [[Hurricane Larry|Larry]] formed on the last day of August and strengthened into a major hurricane early in September. It became the first hurricane to make landfall on [[Newfoundland (island)|Newfoundland]] since [[Hurricane Igor|Igor]] in [[2010 Atlantic hurricane season|2010]]. As the mid-point of the hurricane season approached,{{#tag:ref|September 10 is the climatological mid-point of the Atlantic hurricane season.<ref name=IOTS0909>{{cite web|last=Masters|first=Jeff|title=Mindy hits Florida Panhandle; Cat 1 Larry grazes Bermuda; Cat 4 Chanthu takes aim at Taiwan, and Cat 1 Olaf threatens Baja|date=September 9, 2021|url=https://yaleclimateconnections.org/2021/09/mindy-hits-florida-panhandle-cat-1-larry-grazes-bermuda-cat-4-chanthu-takes-aim-at-taiwan-and-cat-1-olaf-threatens-baja/|publisher=Yale Climate Connections|location=New Haven, Connecticut|access-date=September 9, 2021}}</ref>|group="nb"}} Mindy formed on September 8 and struck the [[Florida Panhandle]] shortly thereafter. It was followed by Nicholas, which developed on September 12 and made landfall along the central [[Texas]] coast two days later as a hurricane. Three tropical storms—Odette, Peter, and Rose—then formed in quick succession and were steered by prevailing winds away from any interaction with land. The busy pace of storm-formation continued late into September. Sam, a long-lived major hurricane, developed in the central tropical Atlantic and proceeded to rapidly intensify from a tropical depression to a hurricane within 24 hours on September 23 and 24. Sam peaked in strength on September 26 as a high-end Category 4 hurricane. It remained a major hurricane (Category 3 or stronger) for nearly eight consecutive days, the longest continuous stretch at that intensity for an Atlantic hurricane since [[Hurricane Ivan|Ivan]], in 2004. Meanwhile, [[Subtropical Storm]] Teresa formed north of Bermuda on September 24. Short-lived Victor developed late in the month at an unusually low [[latitude]] of 8.1°N, tying [[Tropical Storm Kirk (2018)|Kirk in 2018]] and behind only an [[1902 Atlantic hurricane season#Hurricane Three|unnamed 1902 hurricane]] (7.7°N) for the southernmost location in which an Atlantic system has reached tropical storm intensity.<ref name=EOTS92921>{{cite web|last1=Masters|first1=Jeff|last2=Hensen|first2=Bob|title=Hurricane Sam still a Cat 4; Tropical Depression 20 forms off coast of Africa|date=September 29, 2021|url=https://yaleclimateconnections.org/2021/09/hurricane-sam-still-a-cat-4-tropical-depression-20-forms-off-coast-of-africa/|publisher=Yale Climate Connections|location=New Haven, Connecticut|access-date=September 29, 2021}}</ref>

However, [[tropical cyclogenesis]] then paused again for much of the month of October, primarily due to the presence of drier air. For the first time since [[2006 Atlantic hurricane season|2006]] and only the second time during the hyperactive era which began in 1995, no named storms developed between October 6 and October 30. Finally, [[October 2021 nor'easter|Subtropical Storm Wanda]] formed in the central North Atlantic on October 30 and transitioned into a fully tropical storm on November 1. This system was the same storm that previously had brought rain and damaging wind gusts to southern [[New England]] as a potent [[nor'easter]]. Wanda remained a tropical cyclone until transitioning into an extratropical low on November 7, which marked the conclusion of activity during the 2021 Atlantic hurricane season.

{{further|2021 Pacific typhoon season}}
On January 19, a tropical depression formed, becoming the first Northern Hemisphere tropical cyclone of the year and of the 2021 Pacific typhoon season. It brought minor damage to the [[Philippines]]. On February 16, another system formed, with the PAGASA giving it the name ''Auring'' and the JTWC designating the system as ''01W''. On February 17, it was named ''[[Tropical Storm Dujuan (2021)|Dujuan]]'' by the JMA. After passing over [[Palau]], it brought minor damage to the Philippines before dissipating on February 22. On March 14, a tropical depression formed near the [[Sulu Sea]], though it was short-lived and it quickly degenerated back into a low-pressure area. On April 12, a tropical depression formed south of [[Woleai]], and on the next day, the JMA upgraded it to a tropical storm, giving it the name ''[[Typhoon Surigae|Surigae]]''. On April 16, it was given the name Bising by the PAGASA as it entered the [[Philippine Area of Responsibility]]. Surigae underwent [[rapid intensification]], becoming the strongest tropical cyclone to form before May in the Northern Hemisphere. After bringing severe damages to the Philippines, it transitioned into an [[extratropical cyclone]] on April 24 and dissipated on April 30. On May 12, the JTWC began tracking a tropical depression, giving it the designation ''03W'' with the PAGASA assigning it the local name ''Crising''. It made landfall on the Philippines as a weak tropical storm, however damage was minimal due to the storm's small size. Two tropical depressions formed near Palau on May 29 and May 30 respectively, with the former being assigned the name ''Choi-wan'' by the JMA. Choi-wan moved through the Philippines before merging with the [[Meiyu front]] on June 4. After a week gap on June 11, another tropical depression formed over the [[South China Sea]] and it intensified further to a tropical storm named as ''Koguma''. However, it remained short-lived and made landfall over the nation of [[Vietnam]] by the next day and soon dissipated thereafter. After 10 days on June 21, Tropical Storm Champi formed. As a tropical depression, it affected the [[Mariana Islands]] and [[Guam]] before intensifying into a weak typhoon. It became extratropical on 27 June. A tropical depression with its Filipino name, Emong, formed a couple hundred miles from [[Mainland China]]. The storm remained a tropical depression and later dissipated. Another tropical depression formed near Vietnam a couple days later, the storm later made landfall in the country as a weak tropical depression. A tropical depression formed later in the month having the Filipino name Fabian, later intensifying to a tropical storm with the JMA giving it the name ''[[Typhoon In-fa (2021)|In-fa]]''. In-fa later intensified to a typhoon, made several landfalls in China and dissipated on July 31. Meanwhile, [[Tropical Storm Cempaka|Cempaka]] formed in the [[South China Sea]] and made landfall on Southern China and Vietnam causing moderate damage. Later, Tropical Storm Nepartak struck Miyagi Prefecture in [[Japan]]. The system had disturbed the ongoing Summer Olympics held in Japan. Nepartak was also the first tropical storm to hit Miyagi since records began in 1951. By the end of July, activities exploded as 8 systems formed within a week however, 5 of them were rather weak and dissipated without becoming tropical storms. The remaining 3 were named [[Tropical Storm Lupit (2021)|Lupit]], Nida, and Mirinae. [[Tropical Storm Lupit (2021)|Lupit]] affected most of [[East Asia]] while Nida and Mirinae approached [[Japan]] but stayed away from land. Later, a tropical wave from the Central Pacific traveled a long distance and became a tropical storm over the [[Philippine Sea]], which was named Omais (Isang). Omais caused minor damage to [[Ryukyu Islands|The Ryukyu Islands]] and [[South Korea]]. After Omais, the rest of August remained quiet when [[Tropical Storm Conson (2021)|Conson]] formed off the coast of the Philippines and became a typhoon in less than 24 hours. Conson struck the Philippines and Vietnam causing severe damage. Then, [[Typhoon Chanthu (2021)|Chanthu]] formed and became the second super typhoon of the season. Chanthu then headed over to the [[East China Sea]] where the system weakened and stalled. It later made landfall over [[Kyushu]], [[Japan]] and dissipated south of the country. On September 21, two new systems formed and was named Dianmu and Mindulle. Dianmu headed over to [[Vietnam]] where it made landfall. Meanwhile, following Chanthu, Mindulle rapidly intensified into the season's third super typhoon. Mindulle weakened and strengthened multiple times due to cool dry air and cool sea-surface temperatures. Mindulle eventually passed through [[Japan]]'s [[Izu Islands]] causing minor damage. On the start of October, Tropical storm [[Tropical Storm Lionrock (2021)|Lionrock]] formed east of the [[Philippines]] and made landfall on the Chinese Island of [[Hainan]]. Soon, two tropical depressions named ''Maring'' and ''Nando'' formed. However, the two storms eventually merged into Tropical Storm [[Tropical Storm Kompasu (2021)|Kompasu]] due to the storms being close to each other. Kompasu then intensified near typhoon strength and affected the same area where Lionrock had struck. The storm caused severe damage. Later, another tropical depression formed near [[Wake Island]], which was eventually named [[Tropical Storm Namtheun (2021)|Namtheun]]. Namtheun however, stayed away from any landmass and became an [[extratropical cyclone]]. On October 23, a tropical depression formed near [[Guam]] which then was named [[2021 Pacific typhoon season#Typhoon Malou|Malou]]. Malou reached its peak as a Category 2 typhoon but it did not effect any land. A day after Malou formed, another tropical depression formed near the Philippines and the JTWC designating the system as ''26W''. The storm then made landfall over Vietnam and dissipated. In November, [[Typhoon Nyatoh (2021)|Typhon Nyatoh]] being the only storm of the month formed southeast of [[Guam]] and unexpectedly rapidly intensified to a Category 4 super typhoon due to jet interaction. However, it was short lived and the JMA declared the storm became a remnant low. On December, [[Typhoon Rai]] formed very late during the season and struck [[Palau]] and caused severe destruction in the [[Philippines]]. Rai also became a Category 5 super typhoon twice near the Philippines and in the [[South China Sea]]. Rai became the first Category 5 super typhoon since [[Typhoon Nock-ten|Nock-ten]] to form in the month on December. It was also only the third Category 5 super typhoon recorded in the South China Sea, along with [[Typhoon Pamela (1954)|Pamela]] in [[1954 Pacific typhoon season|1954]] and [[Typhoon Rammasun|Rammasun]] in [[2014 Pacific typhoon season|2014]]. Additionally, a tropical depression classified as ''29W'' formed near the equator in the [[South China Sea]]. The depression then made landfall on [[Malaysia]], [[December 2021 Malaysian floods|flooding]] some states within the country.

[[File:2021 North Indian Ocean cyclone season summary.png|260px|thumb|2021 North Indian Ocean cyclone season map]]
On April 2, a tropical depression formed in the north [[Andaman Sea]] near the [[Myanmar]] coast. It remained short-lived, however, dissipating the next day. It was the fourth system to form within the first fifteen days of April since the satellite era began in 1960. Formation during this time is considered rare since the first storm of a season usually forms in mid-April or May. A month later, on May 14, another tropical depression formed in the [[Arabian Sea]]. Later that day, it intensified into a cyclonic storm, being assigned the name ''[[Cyclone Tauktae|Tauktae]]'' by the IMD. It intensified to an extremely severe cyclonic storm and made landfall on [[Gujarat]]. Ten days later another tropical depression formed in the Bay of Bengal in May 23, before strengthening into a cyclonic storm and receiving the name ''[[Cyclone Yaas|Yaas]]''. It rapidly intensified further to a very severe cyclonic storm and made landfall in [[Odisha]]. Both of these storms caused considerable loss of lives and damage. On September 12, after a long period of inactivity, BOB 03 formed. BOB 03 intensified to a deep depression, before making landfall in India. It dissipated on September 15. On September 24, a tropical depression formed in the Bay of Bengal. It was designated BOB 04 by the IMD. In the next two days, it intensified into a cyclonic storm and was named ''[[Cyclones Gulab and Shaheen|Gulab]]''. It made landfall in India. Later, the remnants of Gulab later re-intensified into ''[[Cyclones Gulab and Shaheen|Shaheen]]'' in the [[Arabian Sea]]. Shaheen entered the [[Gulf of Oman]], where it became a Severe Cyclonic Storm. However, it struggled to intensify any further, due to lack of convection. Shaheen eventually made landfall near [[Suwayq|Al Suwaiq]] in the governorate of [[Al Batinah North Governorate|Al Batinah North]] in [[Oman]]. Shaheen became the first cyclone to hit the country since [[Cyclone Hikaa]] in 2019. It was also the first cyclone to enter the [[Gulf of Oman]] since [[Cyclone Gonu]] in 2007. On November 7, ARB 03 formed. It stayed out to sea and dissipated two days later. On November 10, a tropical depression formed. It was designated [[2021 South India floods|BOB 05]] by the IMD. It was short lived, dissipating two days later. However, this depression caused severe flooding in [[Tamil Nadu]] and [[Andhra Pradesh]].

From the 2020 season, two systems crossed into the 2021 season after having formed during the previous year. The systems were Danilo, which peaked as a high-end severe tropical storm and briefly passed near the [[Mascarene Islands]], and a tropical depression designated as 05 which entered the South-West Indian Ocean basin on December 28, causing a [[Fujiwhara effect]] with Danilo before dissipating on January 3. In the 2021 season, a tropical disturbance formed in the South-West Indian Ocean, which intensified into a tropical storm, being given the name [[Cyclone Eloise|Eloise]]. After making landfall on Madagascar, it rapidly intensified into a tropical cyclone in the [[Mozambique Channel]] before making a second landfall on [[Beira, Mozambique|Beira]]. Its remnants affected [[Zimbabwe]], [[Eswatini]], and [[South Africa]]. Joshua entered the basin from the Australian Region on the same day. On January 27, ''10U'' from the Australian region entered the basin and was designated as ''Tropical Depression 09'' before quickly dissipating thereafter.

On February 4, a tropical depression formed and intensified into a tropical cyclone named ''Faraji'' which further intensified into the season's first intense and very intense tropical cyclone. On February 10, a subtropical depression intensified into a tropical cyclone, being named [[Cyclone Guambe|Guambe]] and peaking as a Category 2 equivalent tropical cyclone. On March 1, Marian briefly entered the basin before exiting the basin the next day. On March 2, two tropical disturbances formed, and both intensified, being given the names Habana and Iman respectively. While Iman peaked as a moderate tropical storm and then dissipated, Habana continued to intensify and became the season's second intense tropical cyclone. After a short period of inactivity, a tropical depression designated as ''15'' formed on March 25, though it remained weak and dissipated by March 28.

On April 10, a low-pressure area formed, but due to unfavorable conditions, development was limited. By April 19, the low-pressure area intensified into a tropical depression. The tropical depression intensified shortly into a moderate tropical storm earning the name ''Jobo''. It then rapidly intensified into a tropical cyclone before weakening due to an increase in wind shear, dissipating on April 24. Its remnant made landfall on [[Tanzania]], causing little damages in the area.

At the beginning of the 2021 season, a new tropical low formed in the Australian region near the [[Northern Territory]] of Australia, which further intensified into the first named cyclone of 2021, being given the name [[Cyclone Imogen|Imogen]] before making landfall on [[Far North Queensland]]. Another tropical low formed northeast of the [[Cocos Islands]] which lasted for five days and dissipated on January 10. Joshua formed on January 13 and crossed into the South-West Indian Ocean basin four days later. A new tropical low formed on January 16 near [[Queensland]], which intensified into a cyclone named [[Cyclone Kimi|Kimi]] on the next day. Four additional tropical lows formed after Kimi, of which one managed to intensify into [[Cyclone Lucas]] before crossing into the South Pacific basin on February 3, while the other three had minor effects on land.

In the month of February, four tropical disturbances formed out of which two were named, being given the names [[Cyclone Marian (2021)|Marian]] and [[Cyclone Niran|Niran]] respectively. Marian formed on February 23 and rapidly intensified into a Category 3 severe tropical cyclone on the Australian scale. It briefly entered the MFR's area of responsibility between March 1 and March 2 before re-entering into the basin on March 3, where it peaked as a Category 4 severe tropical cyclone on the Australian Scale. Niran formed on February 27 and also rapidly intensified, peaking as a Category 5 severe tropical cyclone. Although it remained offshore, its slow-motion caused damage to banana crops in Queensland. Niran exited the basin on March 5. In March, three tropical lows developed, though they did not intensify into tropical cyclones.

In the month of April, four systems have formed, with two being named ''[[Cyclone Seroja|Seroja]]'' by TCWC Jakarta and ''[[Cyclone Odette (2021)|Odette]]'' by BoM. The two systems engaged in a Fujiwhara interaction, with Seroja eventually absorbing Odette. The former would go on to intensify and strike [[Australia]] as a Category 3 severe tropical cyclone. On April 9, a tropical low formed off the east coast of Australia and quickly exited on the same day. On April 23, a late-season tropical low formed to the east of the [[Arafura Sea]]. On May 31 a very rare tropical low formed near the [[Cocos (Keeling) Islands|Cocos Islands]] and dissipated without any significant intensification on 4 June.

On November 10, a tropical low formed near the island of [[Sumatra]]. However the storm dissipated a few days later. On November 17, another low formed which then formed into [[Cyclone Paddy|Paddy]]. Following Paddy, another depression formed near the [[Cocos Islands]] before exiting the basin. On November 29, [[Cyclone Teratai|Teratai]] formed south of [[Java]] Island however the cyclone struggled to develop due to the lack of sufficient outflow.

[[Cyclone Ruby|Ruby]] became a named storm on December 12, and intensified to category 1-equivalent strength before crossing into the South Pacific basin on December 13.

In January 2021, four tropical disturbances formed in the South Pacific, all four of which intensified into tropical depressions, with [[Cyclone Ana|Ana]] and [[Cyclone Bina (2021)|Bina]] intensifying into tropical cyclones. On February 1, Lucas entered from the Australian region and affected [[New Caledonia]] and [[Vanuatu]]. A tropical depression designated as ''09F'' formed on February 7, before it was upgraded into a tropical storm by the JTWC. However, it accelerated southwards and became extratropical on February 11. Another tropical depression designated as ''10F'' formed on February 22, before dissipating on February 24. Niran entered the basin on March 5 and caused extensive damage in New Caledonia before accelerating southeast as it transitioned into an extratropical cyclone. On March 5, a short-lived tropical depression designated as ''11F'' existed from March 5 to March 6. On April 9, a tropical depression designated as ''13F'' entered the basin, however, it dissipated on April 11 without intensifying into a tropical cyclone.

On February 6, a weak system unofficially designated as ''01Q'' was briefly tracked by the [[NOAA]]. The system formed and dissipated on the same day without being monitored by the Brazilian Navy. Another system formed on February 14 near [[Rio Grande do Sul]], being designated as a subtropical depression by the Brazilian Navy. On April 19, a subtropical depression formed, although its precursor formed off the coast of [[Rio de Janeiro]]. On April 20 the subtropical depression gained strength and was classified as a subtropical storm by the Brazilian Navy, being assigned the name ''Potira''. It brought gale-force winds to [[Copacabana, Rio de Janeiro|Copacabana]].
On June 28, an extratropical cyclone in [[Uruguay]] transitioned into a subtropical depression on the evening of the same day, being given the designation Invest 1N by the NOAA. A day later, the storm strengthened into a subtropical storm. On June 29, as the subtropical storm entered Brazilian maritime territory, the Brazilian Navy named it ''Raoni''.<ref>{{cite web | url=https://www.marinha.mil.br/chm/dados-do-smm-cartas-sinoticas/cartas-sinoticas | title=Cartas Sinóticas | Centro de Hidrografia da Marinha }}</ref> On December 10, a subtropical cyclone evolved into a subtropical depression and on the morning of the same day it turned into a subtropical storm, called ''Ubá'' by the Brazilian Navy.<ref>{{cite web | url=https://metsul.com/enorme-ciclone-na-costa-do-sul-do-brasil-vira-tempestade-subtropical-uba/ | title=Enorme ciclone na costa do Sul do Brasil vira tempestade subtropical Ubá | date=10 December 2021 }}</ref>

January was unusually above-average, with fourteen tropical cyclones forming and seven being named. Before that, two systems crossed into the 2021 season after having formed during the previous year. Danilo was one of the systems that crossed over, peaking as a severe tropical storm and briefly passing near the Mascarene Islands. A tropical depression designated as 05 entered the South-West Indian Ocean basin on December 28 and caused a brief interaction with Danilo before dissipating on January 3. In the Australian region, Cyclone Imogen formed on January 1 and affected Far North Queensland, bringing minimal damage to the area. Following Imogen, Cyclone Joshua, Cyclone Kimi, and Cyclone Lucas developed, with Joshua later entering the South-West Indian Ocean on January 17. Kimi threatened to strike the coast of Queensland, but weakened suddenly due to unexpected wind shear, remaining just offshore instead. Lucas formed on January 25 and entered the South Pacific basin on February 1. Additionally, four tropical lows formed in the basin, out of which one system entered the South-West Indian Ocean basin. In the South-West Indian Ocean, Cyclone Eloise formed and first made landfall on [[Madagascar]] as a severe tropical storm. It rapidly intensified over the Mozambique Channel and became the strongest storm of the month shortly before making a damaging landfall on [[Mozambique]], with its remnants entering Zimbabwe, Eswatini, and South Africa. In the South Pacific, two tropical depressions formed, which were later assigned the names Ana and Bina, both of them affected [[Fiji]] and Vanuatu. In the West Pacific, a tropical depression formed, which became the first Northern Hemisphere tropical cyclone of 2021 and also marked the beginning of the [[2021 Pacific typhoon season]].

February was slightly above-average, featuring eleven systems, of which five were named. One system was unofficial and another was subtropical. In the Australian region, two tropical lows formed on February 6 and 18 respectively. [[2020–21 Australian region cyclone season#Severe Tropical Cyclone Marian|Cyclone Marian]] formed on February 23 and rapidly intensified, reaching Category 3-equivalent strength on February 28 with Niran following on February 27 and reaching Category 5 strength on both the [[Australian scale]] and the [[Saffir–Simpson scale]], bringing impacts to Queensland and New Caledonia. In the South Pacific, a tropical depression formed north of Fiji and strengthened, though it accelerated southwards and became extratropical on February 11. Another tropical disturbance also briefly existed from February 22 to 24. In the South-West Indian Ocean, [[2020–21 South-West Indian Ocean cyclone season#Very Intense Tropical Cyclone Faraji|Cyclone Faraji]] formed and rapidly intensified, being classified as a very intense tropical cyclone before becoming the strongest storm of the month as it strengthened into the first Category 5-equivalent tropical cyclone in the basin since [[2019–20 South-West Indian Ocean cyclone season#Very Intense Tropical Cyclone Ambali|Cyclone Ambali]] in 2019. It also became the first [[List of South-West Indian Ocean very intense tropical cyclones|very intense tropical cyclone]] recorded in the month of February. It then began to gradually weaken, dissipating on February 13. Another system formed on February 10 and made landfall on Mozambique before re-emerging back over water, and was given the name ''[[Tropical Storm Guambe|Guambe]]'' before reaching tropical cyclone status. In the Western Pacific, Tropical Storm Dujuan formed and became the basin's first named storm, bringing minor damage to the Philippines. In the South Atlantic, one system was unofficially monitored by NOAA, being given the unofficial designation of ''01Q''. However, the Brazilian Navy did not monitor the system. Another system formed near Rio Grande do Sul and was designated as a [[Subtropical cyclone|subtropical depression]] by the Brazilian Navy.

March was slightly below-average, featuring nine tropical cyclones with only two being named. In the Australian region, five tropical lows formed on March 10, 18, 21, and 29 respectively. In the South Pacific, a tropical depression formed and was designated as [[2020–21 South Pacific cyclone season#Other systems|''11F'']], though it was short-lived, dissipating the next day. In the South-West Indian Ocean, [[2020–21 South-West Indian Ocean cyclone season#Intense Tropical Cyclone Habana|Habana]] formed and explosively intensified to an intense tropical cyclone, persisting for two weeks and reaching three individual peak intensities. Forming along with Habana was [[2020–21 South-West Indian Ocean cyclone season#Moderate Tropical Storm Iman|Tropical Storm Iman]], which made landfall on Madagascar as a tropical depression and bringing heavy rainfall to [[Réunion]], dissipating a few days later. In the West Pacific, a tropical depression formed on March 14, however it was short-lived, dissipating the same day.

=== April ===
[[File:Surigae 2021-04-17 0800Z.jpg|thumb|[[Typhoon Surigae]]]]
April was above-average, featuring nine systems, of which five were named. In the Australian region, Cyclone Seroja formed near [[East Timor]] and [[Indonesia]]. Its precursor caused catastrophic damage and deadly landslides in the [[West Nusa Tenggara]] and [[East Nusa Tenggara]] provinces of Indonesia and East Timor, causing 229 fatalities before strengthening to a Category 3 severe tropical cyclone and making a rare landfall on [[Mid West (Western Australia)|Midwestern Australia]], becoming the first since [[Cyclone Elaine|Elaine]] in 1999. Odette also formed in the region near the Cocos Islands before undergoing a [[Fujiwhara interaction]] with Seroja quickly after its formation and later being absorbed by it. Additionally, two tropical lows formed on April 7 and April 9, of which one entered the South Pacific basin. In the North Indian Ocean, a short-lived tropical depression formed off the Myanmar coast in the north Andaman Sea, however it dissipated the next day. In the Australian region, a tropical low formed before later moving into the South Pacific basin, being designated as ''13F''; it was short-lived and dissipated on April 11. In the South-West Indian Ocean, Cyclone Jobo developed near the [[Seychelles]], undergoing a brief period of rapid intensification before dissipating near Tanzania on April 24. In the West Pacific, Typhoon Surigae formed south of Woleai and rapidly intensified into a Category 5-equivalent typhoon, becoming the strongest typhoon recorded in the month of April as it passed near the Philippines, and the strongest tropical cyclone of 2021. In the South Atlantic, [[South Atlantic tropical cyclone#Subtropical Storm Potira|Subtropical Storm Potira]] formed just off the coast of Rio de Janeiro, causing gale-force winds in Copacabana.

=== May ===
[[File:Tauktae 2021-05-17 0835Z.jpg|thumb|[[Cyclone Tauktae]]]]
May was well above average, even though tropical cyclogenesis started in mid-May. It featured the formation of nine systems, with six being named. In the Australian region near the Cocos Islands, an off-season tropical low formed before dissipating on June 3. In the East Pacific, [[2021 Pacific hurricane season#Tropical Storm Andres|Tropical Storm Andres]] formed and peaked as a tropical storm, becoming the earliest named storm in the basin in the East Pacific east of [[140th meridian west|140°W]], breaking the previous record of Adrian in [[2017 Pacific hurricane season|2017]] by twelve hours. [[2021 Pacific hurricane season#Tropical Storm Blanca|Tropical Storm Blanca]] also formed and peaked as a tropical storm near the end of the month. In the North Atlantic, [[2021 Atlantic hurricane season#Tropical Storm Ana|Tropical Storm Ana]] formed northeast of [[Bermuda]] as a subtropical storm before later transitioning into a tropical storm, marking the seventh consecutive Atlantic hurricane season to feature a storm formed before the official start date. In the North Indian Ocean, Cyclone Tauktae formed off the coast of [[Kerala]] and [[Lakshadweep]] and rapidly intensified to Category 4 equivalent storm, becoming the strongest storm of the month. It made a devastating landfall in Gujarat. Ten days later, Cyclone Yaas formed in the [[Bay of Bengal]] and intensified into a Category 1 equivalent strength, eventually making landfall in northwestern Odisha on May 26. Both storms brought considerable damage and loss of lives. In the West Pacific, [[2021 Pacific typhoon season#Tropical Depression Crising|a tropical depression]] formed on May 12 before making landfall on the Philippines and dissipating shortly thereafter. [[Tropical Storm Choi-wan (2021)|Tropical Storm Choi-wan]] and a tropical depression also formed later in the month, with Choi-wan peaking as a tropical storm. Choi-wan made several landfalls in the Philippines, causing severe damage. It later weakened into a tropical depression before transitioning into an extratropical cyclone.

=== August ===
[[File:Ida 2021-08-29 1321Z.jpg|thumb|[[Hurricane Ida]]]]
August was fair-above average, featuring eighteen tropical cyclones, with sixteen of them being named. In the East Pacific, [[2021 Pacific hurricane season#Tropical Storm Ignacio|Tropical Storm Ignacio]] formed, but dissipated a few days later due to strong wind shear partially due to its proximity to Hurricane Hilda. [[2021 Pacific hurricane season#Tropical Storm Kevin|Tropical Storm Kevin]] would then form a couple of days later, off the coast of Mexico with [[2021 Pacific hurricane season#Hurricane Linda|Hurricane Linda]] following shortly after, peaking as a low-end Category 4-equivalent hurricane. Linda was to be followed by [[2021 Pacific hurricane season#Tropical Storm Marty|Tropical Storm Marty]] and [[Hurricane Nora (2021)|Hurricane Nora]]. In the West Pacific, tropical storms [[Tropical Storm Lupit (2021)|Lupit]], [[2021 Pacific typhoon season#Tropical Storm Mirinae|Mirinae]], [[2021 Pacific typhoon season#Severe Tropical Storm Nida|Nida]] and [[2021 Pacific typhoon season#Tropical Storm Omais|Omais]] formed, with Lupit making landfall in [[China]] and [[Japan]]. In the North Atlantic, [[Tropical Storm Fred (2021)|Tropical Storm Fred]] formed south of [[Puerto Rico]] and made landfall in the [[Florida Panhandle]], with Hurricanes [[Hurricane Grace|Grace]] and [[Hurricane Henri|Henri]] forming later. Grace impacted the [[Caribbean]] before making landfall on the [[Yucatán Peninsula]] before rapidly intensifying in the Bay of Campeche and making landfall as a category 3 hurricane in mainland Mexico. Henri would impact the [[Northeastern United States]] as a tropical storm, becoming the first tropical cyclone to make landfall in [[Rhode Island]] since [[Hurricane Bob]] in 1991. At the end of the month, Hurricanes [[Hurricane Ida|Ida]] and [[Hurricane Larry|Larry]], as well as tropical storms [[2021 Atlantic hurricane season#Tropical Storm Julian|Julian]] and
[[2021 Atlantic hurricane season#Tropical Storm Kate|Kate]], and formed. Ida, which became the strongest storm of the month, brought impacts to Cuba before striking Louisiana on August 29, notably on the 16th anniversary of [[Hurricane Katrina]], tying with [[Hurricane Laura]] of [[2020 Atlantic hurricane season|the previous year]] and the [[1856 Last Island Hurricane]] as the strongest hurricane to make landfall in the state by maximum winds.

=== September ===
[[File:Chanthu 2021-09-10 0530Z.png|thumb|[[Typhoon Chanthu (2021)|Typhoon Chanthu]]]]

September was well–above average, featuring nineteen storms, with fifteen of them being named. In the East Pacific, [[Hurricane Olaf (2021)|Hurricane Olaf]] being the only system in the basin, formed on the east coast of Mexico and later made landfall on the [[Baja California Peninsula]] as a Category 2 hurricane. In the West Pacific, Tropical Storms [[2021 Pacific typhoon season#Tropical Storm Conson|Conson]] and [[2021 Pacific typhoon season#Tropical Storm Dianmu|Dianmu]], Typhoons [[Typhoon Chanthu (2021)|Chanthu]] and [[2021 Pacific typhoon season#Typhoon Mindulle|Mindulle]] as well as three short-lived depressions formed, with Chanthu becoming the strongest storm of the month. Conson made a series of landfalls in the [[Philippines]] while Chanthu affected most of [[East Asia]], due to the system stalling in the [[East China Sea]]. Mindulle on the other hand caused minor damage on [[Japan]]'s [[Izu Islands]]. In the Atlantic, (Sub)Tropical Storms [[Tropical Storm Mindy|Mindy]], [[2021 Atlantic hurricane season#Tropical Storm Odette|Odette]], [[2021 Atlantic hurricane season#Tropical Storm Peter|Peter]], [[2021 Atlantic hurricane season#Tropical Storm Rose|Rose]], [[2021 Atlantic hurricane season#Subtropical Storm Teresa|Teresa]], [[2021 Atlantic hurricane season#Tropical Storm Victor|Victor]] as well as Hurricanes [[Hurricane Nicholas|Nicholas]] and [[2021 Atlantic hurricane season#Hurricane Sam|Sam]] formed. Mindy made landfall on [[St. Vincent Island (Florida)|St. Vincent Island]] in Florida, while Nicholas made landfall near [[Sargent, Texas|Sargent]] in [[Texas]]. [[Hurricane Sam]] was a slow moving Category 4 hurricane which traveled across the Atlantic for two weeks. In the North Indian Ocean, [[Cyclones Gulab and Shaheen|Cyclonic Storm Gulab]], [[Cyclones Gulab and Shaheen|Shaheen]] (a regeneration of Gulab), and [[2021 North Indian Ocean cyclone season#Deep Depression BOB 03|BOB 03]] formed. Gulab made landfall in India, causing minor damage. Soon, the remnants of Gulab regenerated into [[Cyclones Gulab and Shaheen|Shaheen]] in the [[Arabian Sea]] west of India. Shaheen entered the [[Gulf of Oman]] and eventually made landfall near [[Suwayq|Al Suwaiq]] in the governorate of [[Al Batinah North Governorate|Al Batinah North]] in [[Oman]]. Shaheen became the first cyclone to hit the country since [[Cyclone Hikaa]] in 2019 and was the first cyclone to hit the area since 1890. It was also the first cyclone to enter the [[Gulf of Oman]] since [[Cyclone Gonu]] in 2007.

===October===
[[File:Malou 2021-10-28 0345Z.jpg|thumb|[[2021 Pacific typhoon season#Typhoon Malou|Typhoon Malou]]]]
October was unusually below-average, featuring only ten storms, with eight of them being named.{{#tag:ref|[[2021 Pacific typhoon season#Tropical Depression Nando|Nando]] isn't included because it's named by the PAGASA not by the JMA.|group="nb"}} The month also includes an unofficial cyclone named [[Cyclone Apollo|Apollo]] which formed in the [[Mediterranean tropical-like cyclone|Mediterranean Sea]]. In the East Pacific, two hurricanes named [[Hurricane Pamela|Pamela]] and [[Hurricane Rick (2021)|Rick]] formed with both of them impacting [[Mexico]]. [[Hurricane Pamela|Pamela]] formed on the southern coast of [[Zihuatanejo]] where it made landfall in [[Sinaloa]] and then rapidly weakened to a tropical depression. Almost a week after Pamela dissipated, [[Hurricane Rick (2021)|Rick]] formed south of Mexico and made landfall on the country as a Category 2 hurricane. In the West Pacific, Typhoon [[2021 Pacific typhoon season#Typhoon Malou|Malou]], Tropical storms [[Tropical Storm Lionrock (2021)|Lionrock]], [[Tropical Storm Kompasu (2021)|Kompasu]], [[2021 Pacific typhoon season#Severe Tropical Storm Namtheun|Namtheun]], and along with two tropical depressions formed. One of the depressions was named [[2021 Pacific typhoon season#Tropical Depression Nando|Nando]] by the PAGASA. Nando formed east of another developing tropical depression, where it then merged with the depression and contributed to the formation of [[Tropical Storm Kompasu (2021)|Kompasu]]. [[Tropical Storm Lionrock (2021)|Lionrock]] struck [[Hong Kong]], [[Southern China]] and [[Vietnam]]. [[Tropical Storm Kompasu (2021)|Kompasu]] also affected the same area where Lionrock struck a week prior, causing severe loss of life and damage. The Atlantic was unusually quiet, only featuring a tropical storm named [[2021 Atlantic hurricane season#Tropical Storm Wanda|Wanda]]. Wanda developed from a strong [[October 2021 nor'easter|late October nor'easter]] that had previously affected much of the [[Northeastern United States]]. The naming of Wanda made the [[2021 Atlantic hurricane season]] the second season in a row after [[2020 Atlantic hurricane season|the previous year]] to run out of names on the standard naming list.

[[File:Nyatoh 2021-12-03 0400Z.jpg|thumb|[[2021 Pacific typhoon season#Typhoon Nyatoh|Typhoon Nyatoh]]]]
November was an average month in terms of activity, featuring eleven storms, of which six were named. The month also includes another unofficial cyclone named [[Storm Blas|Blas]] which formed in the [[Mediterranean tropical-like cyclone|Mediterranean Sea]] near [[Spain]]. In the East Pacific, Tropical Storms [[2021 Pacific hurricane season#Tropical Storm Terry|Terry]] and [[2021 Pacific hurricane season#Tropical Storm Sandra|Sandra]] formed, with both of the storms being named simultaneously on November 7. The West Pacific only featured a super typhoon named [[2021 Pacific typhoon season#Typhoon Nyatoh|Nyatoh]] which developed near [[Guam]], ending the record-long streak without a major tropical cyclone worldwide since October 3. Nyatoh became the strongest cyclone of November, later crossing into December and dissipating. In the North Indian Ocean, three depressions classified as [[2021 North Indian Ocean cyclone season#Depression ARB 03|ARB 03]], [[2021 North Indian Ocean cyclone season#Depression BOB 05|BOB 05]] and [[2021 North Indian Ocean cyclone season#Depression BOB 06|BOB 06]] formed. BOB 05 caused [[2021 South India floods|severe flooding]] in Southern India and [[Sri Lanka]] which killed more than 40 people, with BOB 06 causing additional damages over the same places; the worst damages occurred in the [[Rayalaseema]] region of [[Andhra Pradesh]]. Additionally, a tropical low formed in the Southern Hemisphere which began the [[2021–22 Australian region cyclone season]]. Later, another low formed which was then named ''Paddy''. Following Paddy, a few more depressions formed but dissipated a few days later. At the end of the month, [[2021–22 Australian region cyclone season#Tropical Cyclone Teratai|Tropical Cyclone Teratai]] formed south of [[Java]] but struggled to develop due to the lack of outflow. It then re-strengthened back into a tropical storm before weakening again and dissipating.

===December===
[[File:Rai 2021-12-16 0159Z.jpg|thumb|[[Typhoon Rai]]]]
December was slightly inactive, featuring nine storms, with five of them being named. The month started off with the formation of [[Cyclone Jawad]] which formed in the North Indian Ocean. However, Jawad rapidly weakened due to wind shear shortly after being named, and degenerated into a low-pressure area before it could make landfall over [[West Bengal]]. The Western Pacific featured a tropical depression classified as ''29W'' and a deadly and destructive typhoon, [[Typhoon Rai]]. Rai formed east of [[Palau]] before rapidly intensifying into a Category 5 super typhoon. It then made multiple landfalls on the [[Philippines]] causing serious damage. Rai then entered the [[South China Sea]], re-strengthening into a Category 5 super typhoon east of [[Vietnam]] before dissipating near [[Hong Kong]]. Rai became the first Category 5 super typhoon since [[Typhoon Nock-ten|Nock-ten]] to form in the month on December. It was also the third Category 5 super typhoon recorded in the South China Sea, behind [[Typhoon Pamela (1954)|Pamela]] in [[1954 Pacific typhoon season|1954]] and [[Typhoon Rammasun|Rammasun]] in [[2014 Pacific typhoon season|2014]]. On the other hand, ''29W'' formed near the equator before making landfall on [[Peninsular Malaysia]], [[December 2021 Malaysian floods|flooding]] some states within [[Malaysia]]. The Southern Hemisphere was inactive, only featuring three tropical lows and two cyclones named [[Cyclone Ruby|Ruby]] and [[2021–22 Australian region cyclone season#Tropical Cyclone Seth|Seth]]. Ruby intensified into a Category 2 tropical cyclone on the Australian scale and entered the South Pacific basin, making it the first storm in the basin. Ruby then made landfall on the French overseas island of [[New Caledonia]]. [[2021–22 Australian region cyclone season#Tropical Cyclone Seth|Seth]], on the other hand, first originated in the [[Arafura Sea]]. It then wandered around the northern regions of Australia before being named in the [[Solomon Sea]]. The Southern Atlantic featured its third named storm of the year, [[Subtropical Storm Ubá]].

During 2021, [[tropical cyclone]]s formed in seven major bodies of water, commonly known as [[tropical cyclone basins]]. Tropical cyclones will be assigned names by various weather agencies if they attain [[maximum sustained winds]] of {{convert|35|knots|km/h mph|round=5}}. During the year, 136 systems have formed and 94 were named, including one subtropical depression and excluding one system, which was unofficial. [[Cyclones Gulab and Shaheen|One storm]] was given two names by the same [[Regional Specialized Meteorological Centre|RSMC]]. The most intense storm of the year was [[Typhoon Surigae]], with maximum 10-minute sustained wind speeds of {{cvt|220|km/h|round=10}} and a minimum pressure of {{convert|895|hPa|inHg|sigfig=4|abbr=on|comma=off}}. The deadliest tropical cyclone was [[Typhoon Rai]], which caused 410 fatalities in the [[Philippines]] and 1 in [[Vietnam]], while the costliest was [[Hurricane Ida]], which caused an estimated $75.25 billion [[United States dollar|USD]] in damage after striking [[Louisiana]] and the [[Northeastern United States]].

Like last year, 2021 had an above average amount of tropical cyclones globally. The most active basin of the year was the [[2021 Pacific typhoon season|West Pacific]], which had another below average season, with only 23 named storms. The [[2021 Atlantic hurricane season|North Atlantic]] had another very active season, producing 21 named storms, while the [[2021 Pacific hurricane season|East Pacific]] featured average activity, with 19 named storms forming in the basin. The [[2023 North Indian Ocean cyclone season|North Indian]] basin was also average, featuring 5 named storms. The Southern Hemisphere featured relatively average activity, with Cyclones [[Cyclone Faraji|Faraji]] and [[Cyclone Niran|Niran]] both attaining [[Saffir–Simpson scale|Category 5]] intensity. The rest of the [[Saffir-Simpson scale|Category 5 tropical cyclones]] occurred in the West Pacific, totalling to six [[Saffir-Simpson scale|Category 5 tropical cyclones]] that formed during the year, tying [[Tropical cyclones in 2003|2003]]. However, the number of [[Saffir–Simpson scale|major tropical cyclones]] across the world was below average, with only 16 forming. The [[accumulated cyclone energy]] (ACE) index for 2021 (seven basins combined), as calculated by Colorado State University (CSU) was 621.1 units overall, which was below the 1991-2020 mean of 789.0 units globally.<ref>{{Cite web |[email protected] |title=Annual 2021 Tropical Cyclones Report {{!}} National Centers for Environmental Information (NCEI) |url=https://www.ncei.noaa.gov/access/monitoring/monthly-report/tropical-cyclones/202113 |access-date=2024-03-19 |website=www.ncei.noaa.gov |language=en}}</ref><ref>{{Cite web |title=Global Metrics of Tropical Cyclones |url=https://tropical.atmos.colostate.edu/Realtime/index.php?arch&loc=global}}</ref>

Tropical cyclones are primarily monitored by a group of ten warning centers, which have been designated as a [[Regional Specialized Meteorological Centre]] (RSMC) or a [[Tropical Cyclone Warning Center]] (TCWC) by the [[World Meteorological Organization]]. These are the United States [[National Hurricane Center]] (NHC) and [[Central Pacific Hurricane Center]], the [[Japan Meteorological Agency]] (JMA), the [[Indian Meteorological Department]] (IMD), [[Météo-France]] (MFR), Indonesia's [[Meteorology, Climatology, and Geophysical Agency|Badan Meteorologi, Klimatologi, dan Geofisika]], the Australian [[Bureau of Meteorology]] (BOM), Papua New Guinea's National Weather Service, the [[Fiji Meteorological Service]] (FMS) as well as New Zealand's [[MetService]]. Other notable warning centers include the [[Philippine Atmospheric, Geophysical, and Astronomical Services Administration]] (PAGASA), the United States [[Joint Typhoon Warning Center]] (JTWC), and the [[Brazilian Navy|Brazilian Navy Hydrographic Center (BNHC)]].

[[File:2021 Atlantic hurricane season summary map.png|thumb|2021 Atlantic hurricane season summary map]]
{{further|2021 Atlantic hurricane season}}
The 2021 Atlantic hurricane season officially ran from June 1 to November 30. A total of 21 tropical depressions formed, all of which reached at least tropical or subtropical intensity. The season ranks as the third-most active of all time in the Atlantic basin, behind only [[2005 Atlantic hurricane season|2005]] and [[2020 Atlantic hurricane season|2020]]. Consequently, the 2021 Atlantic hurricane season was the third on record to exhaust its [[Tropical cyclone naming|naming list]]. Nine of the systems lasted for two days or less, tied with [[2007 Atlantic hurricane season|2007]] for the most since the NHC began monitoring subtropical systems in [[1968 Atlantic hurricane season|1968]]. Although the season was highly active in terms of the number of named storms, seven of those tropical or subtropical systems intensified into a hurricane and four of those became a major hurricane, which is near-average and just slightly above-average, respectively. Nonetheless, 2021 marked the record sixth consecutive above-average season in the Atlantic.<ref name="Masters summary">{{cite web|last=Masters|first=Jeff|title=Top-10 weirdest things about the bonkers 2021 Atlantic hurricane season|date=November 30, 2021|url=https://yaleclimateconnections.org/2021/11/top-10-weirdest-things-about-the-bonkers-2021-atlantic-hurricane-season/|publisher=Yale Center for Environmental Communication|location=New Haven, Connecticut|access-date=May 27, 2022}}</ref> The ongoing warm [[Atlantic multidecadal oscillation]], which began in [[1995 Atlantic hurricane season|1995]], contributed to the season's high level of activity, as it led to above-average [[sea surface temperature]]s in the Atlantic basin.

On August 11, Fred formed in the eastern Caribbean, bringing impacts to the [[Greater Antilles|Greater]] and [[Lesser Antilles]], and the Southeastern United States. A few days later, [[Hurricane Grace|Grace]] formed and strengthened into the second hurricane and first major hurricane of the season, and brought impacts to the Greater Antilles and the [[Yucatán Peninsula]], before making landfall in the [[List of states of Mexico|Mexican state]] of [[Veracruz]]. A third tropical system, Henri, developed on August 16, near [[Bermuda]]. Henri meandered for several days before becoming the third hurricane of the season on August 21 and impacted New England, causing record flooding in some places. Towards the end of the month, Hurricane Ida formed, leaving major damage in western Cuba before rapidly intensifying into a Category 4 hurricane and making landfall in southeastern Louisiana at peak intensity, producing widespread, catastrophic damage. Its remnants then generated a [[Hurricane Ida tornado outbreak|deadly tornado outbreak]] and widespread, record-breaking flooding across the Northeastern United States. Two other tropical storms, Julian and Kate, also existed briefly during this time but remained at sea. [[Hurricane Larry|Larry]] formed on the last day of August and strengthened into a major hurricane early in September. It became the first hurricane to make landfall on [[Newfoundland (island)|Newfoundland]] since [[Hurricane Igor|Igor]] in [[2010 Atlantic hurricane season|2010]].

It was followed by Nicholas, which developed on September 12 and made landfall along the central [[Texas]] coast two days later as a hurricane. Three tropical storms—Odette, Peter, and Rose—then formed in quick succession and were steered by prevailing winds away from any interaction with land. The busy pace of storm-formation continued late into September. Sam, a long-lived major hurricane, developed in the central tropical Atlantic and proceeded to rapidly intensify from a tropical depression to a hurricane within 24 hours on September 23 and 24. Sam peaked in strength on September 26 as a high-end Category 4 hurricane. It remained a major hurricane (Category 3 or stronger) for nearly eight consecutive days, the longest continuous stretch at that intensity for an Atlantic hurricane since [[Hurricane Ivan|Ivan]], in 2004. Meanwhile, [[Subtropical Storm]] Teresa formed north of Bermuda on September 24. Short-lived Victor developed late in the month at an unusually low [[latitude]] of 8.1°N, tying [[Tropical Storm Kirk (2018)|Kirk in 2018]] and behind only an [[1902 Atlantic hurricane season#Hurricane Three|unnamed 1902 hurricane]] (7.7°N) for the southernmost location in which an Atlantic system has reached tropical storm intensity.<ref name=EOTS92921>{{cite web|last1=Masters|first1=Jeff|last2=Hensen|first2=Bob|title=Hurricane Sam still a Cat 4; Tropical Depression 20 forms off coast of Africa|date=September 29, 2021|url=https://yaleclimateconnections.org/2021/09/hurricane-sam-still-a-cat-4-tropical-depression-20-forms-off-coast-of-africa/|publisher=Yale Climate Connections|location=New Haven, Connecticut|access-date=September 29, 2021}}</ref>

However, [[tropical cyclogenesis]] then paused again for much of the month of October, primarily due to the presence of drier air. For the first time since [[2006 Atlantic hurricane season|2006]] and only the second time during the hyperactive era which began in 1995, no named storms developed between October 6 and October 30. Finally, [[October 2021 nor'easter|Subtropical Storm Wanda]] formed in the central North Atlantic on October 30 and transitioned into a fully tropical storm on November 1. This system was the same storm that previously had brought rain and damaging wind gusts to southern [[New England]] as a potent [[nor'easter]]. Wanda remained a tropical cyclone until transitioning into an extratropical low on November 7, which marked the conclusion of activity during the 2021 Atlantic hurricane season.

{{further|2021 Pacific typhoon season}}
On January 19, a tropical depression formed, becoming the first Northern Hemisphere tropical cyclone of the year and of the 2021 Pacific typhoon season. It brought minor damage to the [[Philippines]]. On February 16, another system formed, with the PAGASA giving it the name ''Auring'' and the JTWC designating the system as ''01W''. On February 17, it was named ''[[Tropical Storm Dujuan (2021)|Dujuan]]'' by the JMA. After passing over [[Palau]], it brought minor damage to the Philippines before dissipating on February 22. On March 14, a tropical depression formed near the [[Sulu Sea]], though it was short-lived and it quickly degenerated back into a low-pressure area. On April 12, a tropical depression formed south of [[Woleai]], and on the next day, the JMA upgraded it to a tropical storm, giving it the name ''[[Typhoon Surigae|Surigae]]''. On April 16, it was given the name Bising by the PAGASA as it entered the [[Philippine Area of Responsibility]]. Surigae underwent [[rapid intensification]], becoming the strongest tropical cyclone to form before May in the Northern Hemisphere. After bringing severe damages to the Philippines, it transitioned into an [[extratropical cyclone]] on April 24 and dissipated on April 30. On May 12, the JTWC began tracking a tropical depression, giving it the designation ''03W'' with the PAGASA assigning it the local name ''Crising''. It made landfall on the Philippines as a weak tropical storm, however damage was minimal due to the storm's small size. Two tropical depressions formed near Palau on May 29 and May 30 respectively, with the former being assigned the name ''Choi-wan'' by the JMA. Choi-wan moved through the Philippines before merging with the [[Meiyu front]] on June 4. After a week gap on June 11, another tropical depression formed over the [[South China Sea]] and it intensified further to a tropical storm named as ''Koguma''. However, it remained short-lived and made landfall over the nation of [[Vietnam]] by the next day and soon dissipated thereafter. After 10 days on June 21, Tropical Storm Champi formed. As a tropical depression, it affected the [[Mariana Islands]] and [[Guam]] before intensifying into a weak typhoon. It became extratropical on 27 June. A tropical depression with its Filipino name, Emong, formed a couple hundred miles from [[Mainland China]]. The storm remained a tropical depression and later dissipated. Another tropical depression formed near Vietnam a couple days later, the storm later made landfall in the country as a weak tropical depression. A tropical depression formed later in the month having the Filipino name Fabian, later intensifying to a tropical storm with the JMA giving it the name ''[[Typhoon In-fa (2021)|In-fa]]''. In-fa later intensified to a typhoon, made several landfalls in China and dissipated on July 31. Meanwhile, [[Tropical Storm Cempaka|Cempaka]] formed in the [[South China Sea]] and made landfall on Southern China and Vietnam causing moderate damage. Later, Tropical Storm Nepartak struck Miyagi Prefecture in [[Japan]]. The system had disturbed the ongoing Summer Olympics held in Japan. Nepartak was also the first tropical storm to hit Miyagi since records began in 1951. By the end of July, activities exploded as 8 systems formed within a week however, 5 of them were rather weak and dissipated without becoming tropical storms. The remaining 3 were named [[Tropical Storm Lupit (2021)|Lupit]], Nida, and Mirinae. [[Tropical Storm Lupit (2021)|Lupit]] affected most of [[East Asia]] while Nida and Mirinae approached [[Japan]] but stayed away from land. Later, a tropical wave from the Central Pacific traveled a long distance and became a tropical storm over the [[Philippine Sea]], which was named Omais (Isang). Omais caused minor damage to [[Ryukyu Islands|The Ryukyu Islands]] and [[South Korea]]. After Omais, the rest of August remained quiet when [[Tropical Storm Conson (2021)|Conson]] formed off the coast of the Philippines and became a typhoon in less than 24 hours. Conson struck the Philippines and Vietnam causing severe damage. Then, [[Typhoon Chanthu (2021)|Chanthu]] formed and became the second super typhoon of the season. Chanthu then headed over to the [[East China Sea]] where the system weakened and stalled. It later made landfall over [[Kyushu]], [[Japan]] and dissipated south of the country. On September 21, two new systems formed and was named Dianmu and Mindulle. Dianmu headed over to [[Vietnam]] where it made landfall. Meanwhile, following Chanthu, Mindulle rapidly intensified into the season's third super typhoon. Mindulle weakened and strengthened multiple times due to cool dry air and cool sea-surface temperatures. Mindulle eventually passed through [[Japan]]'s [[Izu Islands]] causing minor damage. On the start of October, Tropical storm [[Tropical Storm Lionrock (2021)|Lionrock]] formed east of the [[Philippines]] and made landfall on the Chinese Island of [[Hainan]]. Soon, two tropical depressions named ''Maring'' and ''Nando'' formed. However, the two storms eventually merged into Tropical Storm [[Tropical Storm Kompasu (2021)|Kompasu]] due to the storms being close to each other. Kompasu then intensified near typhoon strength and affected the same area where Lionrock had struck. The storm caused severe damage. Later, another tropical depression formed near [[Wake Island]], which was eventually named [[Tropical Storm Namtheun (2021)|Namtheun]]. Namtheun however, stayed away from any landmass and became an [[extratropical cyclone]]. On October 23, a tropical depression formed near [[Guam]] which then was named [[2021 Pacific typhoon season#Typhoon Malou|Malou]]. Malou reached its peak as a Category 2 typhoon but it did not effect any land. A day after Malou formed, another tropical depression formed near the Philippines and the JTWC designating the system as ''26W''. The storm then made landfall over Vietnam and dissipated. In November, [[Typhoon Nyatoh (2021)|Typhon Nyatoh]] being the only storm of the month formed southeast of [[Guam]] and unexpectedly rapidly intensified to a Category 4 super typhoon due to jet interaction. However, it was short lived and the JMA declared the storm became a remnant low. On December, [[Typhoon Rai]] formed very late during the season and struck [[Palau]] and caused severe destruction in the [[Philippines]]. Rai also became a Category 5 super typhoon twice near the Philippines and in the [[South China Sea]]. Rai became the first Category 5 super typhoon since [[Typhoon Nock-ten|Nock-ten]] to form in the month on December. It was also only the third Category 5 super typhoon recorded in the South China Sea, along with [[Typhoon Pamela (1954)|Pamela]] in [[1954 Pacific typhoon season|1954]] and [[Typhoon Rammasun|Rammasun]] in [[2014 Pacific typhoon season|2014]]. Additionally, a tropical depression classified as ''29W'' formed near the equator in the [[South China Sea]]. The depression then made landfall on [[Malaysia]], [[December 2021 Malaysian floods|flooding]] some states within the country.

On April 2, a tropical depression formed in the north [[Andaman Sea]] near the [[Myanmar]] coast. It remained short-lived, however, dissipating the next day. It was the fourth system to form within the first fifteen days of April since the satellite era began in 1960. Formation during this time is considered rare since the first storm of a season usually forms in mid-April or May. A month later, on May 14, another tropical depression formed in the [[Arabian Sea]]. Later that day, it intensified into a cyclonic storm, being assigned the name ''[[Cyclone Tauktae|Tauktae]]'' by the IMD. It intensified to an extremely severe cyclonic storm and made landfall on [[Gujarat]]. Ten days later another tropical depression formed in the Bay of Bengal in May 23, before strengthening into a cyclonic storm and receiving the name ''[[Cyclone Yaas|Yaas]]''. It rapidly intensified further to a very severe cyclonic storm and made landfall in [[Odisha]]. Both of these storms caused considerable loss of lives and damage. On September 12, after a long period of inactivity, BOB 03 formed. BOB 03 intensified to a deep depression, before making landfall in India. It dissipated on September 15. On September 24, a tropical depression formed in the Bay of Bengal. It was designated BOB 04 by the IMD. In the next two days, it intensified into a cyclonic storm and was named ''[[Cyclones Gulab and Shaheen|Gulab]]''. It made landfall in India. Later, the remnants of Gulab later re-intensified into ''[[Cyclones Gulab and Shaheen|Shaheen]]'' in the [[Arabian Sea]]. Shaheen entered the [[Gulf of Oman]], where it became a Severe Cyclonic Storm. However, it struggled to intensify any further, due to lack of convection. Shaheen eventually made landfall near [[Suwayq|Al Suwaiq]] in the governorate of [[Al Batinah North Governorate|Al Batinah North]] in [[Oman]]. Shaheen became the first cyclone to hit the country since [[Cyclone Hikaa]] in 2019. It was also the first cyclone to enter the [[Gulf of Oman]] since [[Cyclone Gonu]] in 2007. On November 7, ARB 03 formed. It stayed out to sea and dissipated two days later. On November 10, a tropical depression formed. It was designated [[2021 South India floods|BOB 05]] by the IMD. It was short lived, dissipating two days later. However, this depression caused severe flooding in [[Tamil Nadu]] and [[Andhra Pradesh]].

From the 2020 season, two systems crossed into the 2021 season after having formed during the previous year. The systems were Danilo, which peaked as a high-end severe tropical storm and briefly passed near the [[Mascarene Islands]], and a tropical depression designated as 05 which entered the South-West Indian Ocean basin on December 28, causing a [[Fujiwhara effect]] with Danilo before dissipating on January 3. In the 2021 season, a tropical disturbance formed in the South-West Indian Ocean, which intensified into a tropical storm, being given the name [[Cyclone Eloise|Eloise]]. After making landfall on Madagascar, it rapidly intensified into a tropical cyclone in the [[Mozambique Channel]] before making a second landfall on [[Beira, Mozambique|Beira]]. Its remnants affected [[Zimbabwe]], [[Eswatini]], and [[South Africa]]. Joshua entered the basin from the Australian Region on the same day. On January 27, ''10U'' from the Australian region entered the basin and was designated as ''Tropical Depression 09'' before quickly dissipating thereafter.

On February 4, a tropical depression formed and intensified into a tropical cyclone named ''Faraji'' which further intensified into the season's first intense and very intense tropical cyclone. On February 10, a subtropical depression intensified into a tropical cyclone, being named [[Cyclone Guambe|Guambe]] and peaking as a Category 2 equivalent tropical cyclone. On March 1, Marian briefly entered the basin before exiting the basin the next day. On March 2, two tropical disturbances formed, and both intensified, being given the names Habana and Iman respectively. While Iman peaked as a moderate tropical storm and then dissipated, Habana continued to intensify and became the season's second intense tropical cyclone. After a short period of inactivity, a tropical depression designated as ''15'' formed on March 25, though it remained weak and dissipated by March 28.

On April 10, a low-pressure area formed, but due to unfavorable conditions, development was limited. By April 19, the low-pressure area intensified into a tropical depression. The tropical depression intensified shortly into a moderate tropical storm earning the name ''Jobo''. It then rapidly intensified into a tropical cyclone before weakening due to an increase in wind shear, dissipating on April 24. Its remnant made landfall on [[Tanzania]], causing little damages in the area.

At the beginning of the 2021 season, a new tropical low formed in the Australian region near the [[Northern Territory]] of Australia, which further intensified into the first named cyclone of 2021, being given the name [[Cyclone Imogen|Imogen]] before making landfall on [[Far North Queensland]]. Another tropical low formed northeast of the [[Cocos Islands]] which lasted for five days and dissipated on January 10. Joshua formed on January 13 and crossed into the South-West Indian Ocean basin four days later. A new tropical low formed on January 16 near [[Queensland]], which intensified into a cyclone named [[Cyclone Kimi|Kimi]] on the next day. Four additional tropical lows formed after Kimi, of which one managed to intensify into [[Cyclone Lucas]] before crossing into the South Pacific basin on February 3, while the other three had minor effects on land.

In the month of February, four tropical disturbances formed out of which two were named, being given the names [[Cyclone Marian (2021)|Marian]] and [[Cyclone Niran|Niran]] respectively. Marian formed on February 23 and rapidly intensified into a Category 3 severe tropical cyclone on the Australian scale. It briefly entered the MFR's area of responsibility between March 1 and March 2 before re-entering into the basin on March 3, where it peaked as a Category 4 severe tropical cyclone on the Australian Scale. Niran formed on February 27 and also rapidly intensified, peaking as a Category 5 severe tropical cyclone. Although it remained offshore, its slow-motion caused damage to banana crops in Queensland. Niran exited the basin on March 5. In March, three tropical lows developed, though they did not intensify into tropical cyclones.

In the month of April, four systems have formed, with two being named ''[[Cyclone Seroja|Seroja]]'' by TCWC Jakarta and ''[[Cyclone Odette (2021)|Odette]]'' by BoM. The two systems engaged in a Fujiwhara interaction, with Seroja eventually absorbing Odette. The former would go on to intensify and strike [[Australia]] as a Category 3 severe tropical cyclone. On April 9, a tropical low formed off the east coast of Australia and quickly exited on the same day. On April 23, a late-season tropical low formed to the east of the [[Arafura Sea]]. On May 31 a very rare tropical low formed near the [[Cocos (Keeling) Islands|Cocos Islands]] and dissipated without any significant intensification on 4 June.

On November 10, a tropical low formed near the island of [[Sumatra]]. However the storm dissipated a few days later. On November 17, another low formed which then formed into [[Cyclone Paddy|Paddy]]. Following Paddy, another depression formed near the [[Cocos Islands]] before exiting the basin. On November 29, [[Cyclone Teratai|Teratai]] formed south of [[Java]] Island however the cyclone struggled to develop due to the lack of sufficient outflow.

[[Cyclone Ruby|Ruby]] became a named storm on December 12, and intensified to category 1-equivalent strength before crossing into the South Pacific basin on December 13.

In January 2021, four tropical disturbances formed in the South Pacific, all four of which intensified into tropical depressions, with [[Cyclone Ana|Ana]] and [[Cyclone Bina (2021)|Bina]] intensifying into tropical cyclones. On February 1, Lucas entered from the Australian region and affected [[New Caledonia]] and [[Vanuatu]]. A tropical depression designated as ''09F'' formed on February 7, before it was upgraded into a tropical storm by the JTWC. However, it accelerated southwards and became extratropical on February 11. Another tropical depression designated as ''10F'' formed on February 22, before dissipating on February 24. Niran entered the basin on March 5 and caused extensive damage in New Caledonia before accelerating southeast as it transitioned into an extratropical cyclone. On March 5, a short-lived tropical depression designated as ''11F'' existed from March 5 to March 6. On April 9, a tropical depression designated as ''13F'' entered the basin, however, it dissipated on April 11 without intensifying into a tropical cyclone.

On February 6, a weak system unofficially designated as ''01Q'' was briefly tracked by the [[NOAA]]. The system formed and dissipated on the same day without being monitored by the Brazilian Navy. Another system formed on February 14 near [[Rio Grande do Sul]], being designated as a subtropical depression by the Brazilian Navy. On April 19, a subtropical depression formed, although its precursor formed off the coast of [[Rio de Janeiro]]. On April 20 the subtropical depression gained strength and was classified as a subtropical storm by the Brazilian Navy, being assigned the name ''Potira''. It brought gale-force winds to [[Copacabana, Rio de Janeiro|Copacabana]].
On June 28, an extratropical cyclone in [[Uruguay]] transitioned into a subtropical depression on the evening of the same day, being given the designation Invest 1N by the NOAA. A day later, the storm strengthened into a subtropical storm. On June 29, as the subtropical storm entered Brazilian maritime territory, the Brazilian Navy named it ''Raoni''.<ref>{{cite web | url=https://www.marinha.mil.br/chm/dados-do-smm-cartas-sinoticas/cartas-sinoticas | title=Cartas Sinóticas | Centro de Hidrografia da Marinha }}</ref> On December 10, a subtropical cyclone evolved into a subtropical depression and on the morning of the same day it turned into a subtropical storm, called ''Ubá'' by the Brazilian Navy.<ref>{{cite web | url=https://metsul.com/enorme-ciclone-na-costa-do-sul-do-brasil-vira-tempestade-subtropical-uba/ | title=Enorme ciclone na costa do Sul do Brasil vira tempestade subtropical Ubá | date=10 December 2021 }}</ref>

January was unusually above-average, with fourteen tropical cyclones forming and seven being named. Before that, two systems crossed into the 2021 season after having formed during the previous year. Danilo was one of the systems that crossed over, peaking as a severe tropical storm and briefly passing near the Mascarene Islands. A tropical depression designated as 05 entered the South-West Indian Ocean basin on December 28 and caused a brief interaction with Danilo before dissipating on January 3. In the Australian region, Cyclone Imogen formed on January 1 and affected Far North Queensland, bringing minimal damage to the area. Following Imogen, Cyclone Joshua, Cyclone Kimi, and Cyclone Lucas developed, with Joshua later entering the South-West Indian Ocean on January 17. Kimi threatened to strike the coast of Queensland, but weakened suddenly due to unexpected wind shear, remaining just offshore instead. Lucas formed on January 25 and entered the South Pacific basin on February 1. Additionally, four tropical lows formed in the basin, out of which one system entered the South-West Indian Ocean basin. In the South-West Indian Ocean, Cyclone Eloise formed and first made landfall on [[Madagascar]] as a severe tropical storm. It rapidly intensified over the Mozambique Channel and became the strongest storm of the month shortly before making a damaging landfall on [[Mozambique]], with its remnants entering Zimbabwe, Eswatini, and South Africa. In the South Pacific, two tropical depressions formed, which were later assigned the names Ana and Bina, both of them affected [[Fiji]] and Vanuatu. In the West Pacific, a tropical depression formed, which became the first Northern Hemisphere tropical cyclone of 2021 and also marked the beginning of the [[2021 Pacific typhoon season]].

February was slightly above-average, featuring eleven systems, of which five were named. One system was unofficial and another was subtropical. In the Australian region, two tropical lows formed on February 6 and 18 respectively. [[2020–21 Australian region cyclone season#Severe Tropical Cyclone Marian|Cyclone Marian]] formed on February 23 and rapidly intensified, reaching Category 3-equivalent strength on February 28 with Niran following on February 27 and reaching Category 5 strength on both the [[Australian scale]] and the [[Saffir–Simpson scale]], bringing impacts to Queensland and New Caledonia. In the South Pacific, a tropical depression formed north of Fiji and strengthened, though it accelerated southwards and became extratropical on February 11. Another tropical disturbance also briefly existed from February 22 to 24. In the South-West Indian Ocean, [[2020–21 South-West Indian Ocean cyclone season#Very Intense Tropical Cyclone Faraji|Cyclone Faraji]] formed and rapidly intensified, being classified as a very intense tropical cyclone before becoming the strongest storm of the month as it strengthened into the first Category 5-equivalent tropical cyclone in the basin since [[2019–20 South-West Indian Ocean cyclone season#Very Intense Tropical Cyclone Ambali|Cyclone Ambali]] in 2019. It also became the first [[List of South-West Indian Ocean very intense tropical cyclones|very intense tropical cyclone]] recorded in the month of February. It then began to gradually weaken, dissipating on February 13. Another system formed on February 10 and made landfall on Mozambique before re-emerging back over water, and was given the name ''[[Tropical Storm Guambe|Guambe]]'' before reaching tropical cyclone status. In the Western Pacific, Tropical Storm Dujuan formed and became the basin's first named storm, bringing minor damage to the Philippines. In the South Atlantic, one system was unofficially monitored by NOAA, being given the unofficial designation of ''01Q''. However, the Brazilian Navy did not monitor the system. Another system formed near Rio Grande do Sul and was designated as a [[Subtropical cyclone|subtropical depression]] by the Brazilian Navy.

=== March ===
{{Unreferenced section|date=January 2023}}
[[File:Habana 2021-03-10 0840Z.jpg|thumb|[[Cyclone Habana]]]]
March was slightly below-average, featuring nine tropical cyclones with only two being named. In the Australian region, five tropical lows formed on March 10, 18, 21, and 29 respectively. In the South Pacific, a tropical depression formed and was designated as [[2020–21 South Pacific cyclone season#Other systems|''11F'']], though it was short-lived, dissipating the next day. In the South-West Indian Ocean, [[2020–21 South-West Indian Ocean cyclone season#Intense Tropical Cyclone Habana|Habana]] formed and explosively intensified to an intense tropical cyclone, persisting for two weeks and reaching three individual peak intensities. Forming along with Habana was [[2020–21 South-West Indian Ocean cyclone season#Moderate Tropical Storm Iman|Tropical Storm Iman]], which made landfall on Madagascar as a tropical depression and bringing heavy rainfall to [[Réunion]], dissipating a few days later. In the West Pacific, a tropical depression formed on March 14, however it was short-lived, dissipating the same day.

=== April ===
[[File:Surigae 2021-04-17 0800Z.jpg|thumb|[[Typhoon Surigae]]]]
April was above-average, featuring nine systems, of which five were named. In the Australian region, Cyclone Seroja formed near [[East Timor]] and [[Indonesia]]. Its precursor caused catastrophic damage and deadly landslides in the [[West Nusa Tenggara]] and [[East Nusa Tenggara]] provinces of Indonesia and East Timor, causing 229 fatalities before strengthening to a Category 3 severe tropical cyclone and making a rare landfall on [[Mid West (Western Australia)|Midwestern Australia]], becoming the first since [[Cyclone Elaine|Elaine]] in 1999. Odette also formed in the region near the Cocos Islands before undergoing a [[Fujiwhara interaction]] with Seroja quickly after its formation and later being absorbed by it. Additionally, two tropical lows formed on April 7 and April 9, of which one entered the South Pacific basin. In the North Indian Ocean, a short-lived tropical depression formed off the Myanmar coast in the north Andaman Sea, however it dissipated the next day. In the Australian region, a tropical low formed before later moving into the South Pacific basin, being designated as ''13F''; it was short-lived and dissipated on April 11. In the South-West Indian Ocean, Cyclone Jobo developed near the [[Seychelles]], undergoing a brief period of rapid intensification before dissipating near Tanzania on April 24. In the West Pacific, Typhoon Surigae formed south of Woleai and rapidly intensified into a Category 5-equivalent typhoon, becoming the strongest typhoon recorded in the month of April as it passed near the Philippines, and the strongest tropical cyclone of 2021. In the South Atlantic, [[South Atlantic tropical cyclone#Subtropical Storm Potira|Subtropical Storm Potira]] formed just off the coast of Rio de Janeiro, causing gale-force winds in Copacabana.

[[File:Tauktae 2021-05-17 0835Z.jpg|thumb|[[Cyclone Tauktae]]]]
May was well above average, even though tropical cyclogenesis started in mid-May. It featured the formation of nine systems, with six being named. In the Australian region near the Cocos Islands, an off-season tropical low formed before dissipating on June 3. In the East Pacific, [[2021 Pacific hurricane season#Tropical Storm Andres|Tropical Storm Andres]] formed and peaked as a tropical storm, becoming the earliest named storm in the basin in the East Pacific east of [[140th meridian west|140°W]], breaking the previous record of Adrian in [[2017 Pacific hurricane season|2017]] by twelve hours. [[2021 Pacific hurricane season#Tropical Storm Blanca|Tropical Storm Blanca]] also formed and peaked as a tropical storm near the end of the month. In the North Atlantic, [[2021 Atlantic hurricane season#Tropical Storm Ana|Tropical Storm Ana]] formed northeast of [[Bermuda]] as a subtropical storm before later transitioning into a tropical storm, marking the seventh consecutive Atlantic hurricane season to feature a storm formed before the official start date. In the North Indian Ocean, Cyclone Tauktae formed off the coast of [[Kerala]] and [[Lakshadweep]] and rapidly intensified to Category 4 equivalent storm, becoming the strongest storm of the month. It made a devastating landfall in Gujarat. Ten days later, Cyclone Yaas formed in the [[Bay of Bengal]] and intensified into a Category 1 equivalent strength, eventually making landfall in northwestern Odisha on May 26. Both storms brought considerable damage and loss of lives. In the West Pacific, [[2021 Pacific typhoon season#Tropical Depression Crising|a tropical depression]] formed on May 12 before making landfall on the Philippines and dissipating shortly thereafter. [[Tropical Storm Choi-wan (2021)|Tropical Storm Choi-wan]] and a tropical depression also formed later in the month, with Choi-wan peaking as a tropical storm. Choi-wan made several landfalls in the Philippines, causing severe damage. It later weakened into a tropical depression before transitioning into an extratropical cyclone.

[[2021 Pacific hurricane season#Hurricane Hilda|Hurricane Hilda]] would then form at the end of the month. In the West Pacific, two tropical depressions formed and were designated as ''07W'' and ''08W'' respectively. The former received the name ''Emong'' from PAGASA. Further into the month, two typhoons named [[Typhoon In-fa|In-fa]] and [[Typhoon Cempaka|Cempaka]] and [[2021 Pacific typhoon season#Tropical Storm Nepartak|Tropical Storm Nepartak]] formed, with In-fa making landfall in China as severe tropical storm while Cempaka made landfall in Southern China as a typhoon; both were associated with the [[2021 Henan floods]]. Nepartak, on the other hand, made landfall on the Miyagi Prefecture in Japan. The storm disturbed the ongoing Summer Olympics held in the country.

=== August ===
[[File:Ida 2021-08-29 1321Z.jpg|thumb|[[Hurricane Ida]]]]
August was fair-above average, featuring eighteen tropical cyclones, with sixteen of them being named. In the East Pacific, [[2021 Pacific hurricane season#Tropical Storm Ignacio|Tropical Storm Ignacio]] formed, but dissipated a few days later due to strong wind shear partially due to its proximity to Hurricane Hilda. [[2021 Pacific hurricane season#Tropical Storm Kevin|Tropical Storm Kevin]] would then form a couple of days later, off the coast of Mexico with [[2021 Pacific hurricane season#Hurricane Linda|Hurricane Linda]] following shortly after, peaking as a low-end Category 4-equivalent hurricane. Linda was to be followed by [[2021 Pacific hurricane season#Tropical Storm Marty|Tropical Storm Marty]] and [[Hurricane Nora (2021)|Hurricane Nora]]. In the West Pacific, tropical storms [[Tropical Storm Lupit (2021)|Lupit]], [[2021 Pacific typhoon season#Tropical Storm Mirinae|Mirinae]], [[2021 Pacific typhoon season#Severe Tropical Storm Nida|Nida]] and [[2021 Pacific typhoon season#Tropical Storm Omais|Omais]] formed, with Lupit making landfall in [[China]] and [[Japan]]. In the North Atlantic, [[Tropical Storm Fred (2021)|Tropical Storm Fred]] formed south of [[Puerto Rico]] and made landfall in the [[Florida Panhandle]], with Hurricanes [[Hurricane Grace|Grace]] and [[Hurricane Henri|Henri]] forming later. Grace impacted the [[Caribbean]] before making landfall on the [[Yucatán Peninsula]] before rapidly intensifying in the Bay of Campeche and making landfall as a category 3 hurricane in mainland Mexico. Henri would impact the [[Northeastern United States]] as a tropical storm, becoming the first tropical cyclone to make landfall in [[Rhode Island]] since [[Hurricane Bob]] in 1991. At the end of the month, Hurricanes [[Hurricane Ida|Ida]] and [[Hurricane Larry|Larry]], as well as tropical storms [[2021 Atlantic hurricane season#Tropical Storm Julian|Julian]] and
[[2021 Atlantic hurricane season#Tropical Storm Kate|Kate]], and formed. Ida, which became the strongest storm of the month, brought impacts to Cuba before striking Louisiana on August 29, notably on the 16th anniversary of [[Hurricane Katrina]], tying with [[Hurricane Laura]] of [[2020 Atlantic hurricane season|the previous year]] and the [[1856 Last Island Hurricane]] as the strongest hurricane to make landfall in the state by maximum winds.

=== September ===
[[File:Chanthu 2021-09-10 0530Z.png|thumb|[[Typhoon Chanthu (2021)|Typhoon Chanthu]]]]

September was well–above average, featuring nineteen storms, with fifteen of them being named. In the East Pacific, [[Hurricane Olaf (2021)|Hurricane Olaf]] being the only system in the basin, formed on the east coast of Mexico and later made landfall on the [[Baja California Peninsula]] as a Category 2 hurricane. In the West Pacific, Tropical Storms [[2021 Pacific typhoon season#Tropical Storm Conson|Conson]] and [[2021 Pacific typhoon season#Tropical Storm Dianmu|Dianmu]], Typhoons [[Typhoon Chanthu (2021)|Chanthu]] and [[2021 Pacific typhoon season#Typhoon Mindulle|Mindulle]] as well as three short-lived depressions formed, with Chanthu becoming the strongest storm of the month. Conson made a series of landfalls in the [[Philippines]] while Chanthu affected most of [[East Asia]], due to the system stalling in the [[East China Sea]]. Mindulle on the other hand caused minor damage on [[Japan]]'s [[Izu Islands]]. In the Atlantic, (Sub)Tropical Storms [[Tropical Storm Mindy|Mindy]], [[2021 Atlantic hurricane season#Tropical Storm Odette|Odette]], [[2021 Atlantic hurricane season#Tropical Storm Peter|Peter]], [[2021 Atlantic hurricane season#Tropical Storm Rose|Rose]], [[2021 Atlantic hurricane season#Subtropical Storm Teresa|Teresa]], [[2021 Atlantic hurricane season#Tropical Storm Victor|Victor]] as well as Hurricanes [[Hurricane Nicholas|Nicholas]] and [[2021 Atlantic hurricane season#Hurricane Sam|Sam]] formed. Mindy made landfall on [[St. Vincent Island (Florida)|St. Vincent Island]] in Florida, while Nicholas made landfall near [[Sargent, Texas|Sargent]] in [[Texas]]. [[Hurricane Sam]] was a slow moving Category 4 hurricane which traveled across the Atlantic for two weeks. In the North Indian Ocean, [[Cyclones Gulab and Shaheen|Cyclonic Storm Gulab]], [[Cyclones Gulab and Shaheen|Shaheen]] (a regeneration of Gulab), and [[2021 North Indian Ocean cyclone season#Deep Depression BOB 03|BOB 03]] formed. Gulab made landfall in India, causing minor damage. Soon, the remnants of Gulab regenerated into [[Cyclones Gulab and Shaheen|Shaheen]] in the [[Arabian Sea]] west of India. Shaheen entered the [[Gulf of Oman]] and eventually made landfall near [[Suwayq|Al Suwaiq]] in the governorate of [[Al Batinah North Governorate|Al Batinah North]] in [[Oman]]. Shaheen became the first cyclone to hit the country since [[Cyclone Hikaa]] in 2019 and was the first cyclone to hit the area since 1890. It was also the first cyclone to enter the [[Gulf of Oman]] since [[Cyclone Gonu]] in 2007.

===October===
[[File:Malou 2021-10-28 0345Z.jpg|thumb|[[2021 Pacific typhoon season#Typhoon Malou|Typhoon Malou]]]]
October was unusually below-average, featuring only ten storms, with eight of them being named.{{#tag:ref|[[2021 Pacific typhoon season#Tropical Depression Nando|Nando]] isn't included because it's named by the PAGASA not by the JMA.|group="nb"}} The month also includes an unofficial cyclone named [[Cyclone Apollo|Apollo]] which formed in the [[Mediterranean tropical-like cyclone|Mediterranean Sea]]. In the East Pacific, two hurricanes named [[Hurricane Pamela|Pamela]] and [[Hurricane Rick (2021)|Rick]] formed with both of them impacting [[Mexico]]. [[Hurricane Pamela|Pamela]] formed on the southern coast of [[Zihuatanejo]] where it made landfall in [[Sinaloa]] and then rapidly weakened to a tropical depression. Almost a week after Pamela dissipated, [[Hurricane Rick (2021)|Rick]] formed south of Mexico and made landfall on the country as a Category 2 hurricane. In the West Pacific, Typhoon [[2021 Pacific typhoon season#Typhoon Malou|Malou]], Tropical storms [[Tropical Storm Lionrock (2021)|Lionrock]], [[Tropical Storm Kompasu (2021)|Kompasu]], [[2021 Pacific typhoon season#Severe Tropical Storm Namtheun|Namtheun]], and along with two tropical depressions formed. One of the depressions was named [[2021 Pacific typhoon season#Tropical Depression Nando|Nando]] by the PAGASA. Nando formed east of another developing tropical depression, where it then merged with the depression and contributed to the formation of [[Tropical Storm Kompasu (2021)|Kompasu]]. [[Tropical Storm Lionrock (2021)|Lionrock]] struck [[Hong Kong]], [[Southern China]] and [[Vietnam]]. [[Tropical Storm Kompasu (2021)|Kompasu]] also affected the same area where Lionrock struck a week prior, causing severe loss of life and damage. The Atlantic was unusually quiet, only featuring a tropical storm named [[2021 Atlantic hurricane season#Tropical Storm Wanda|Wanda]]. Wanda developed from a strong [[October 2021 nor'easter|late October nor'easter]] that had previously affected much of the [[Northeastern United States]]. The naming of Wanda made the [[2021 Atlantic hurricane season]] the second season in a row after [[2020 Atlantic hurricane season|the previous year]] to run out of names on the standard naming list.

[[File:Nyatoh 2021-12-03 0400Z.jpg|thumb|[[2021 Pacific typhoon season#Typhoon Nyatoh|Typhoon Nyatoh]]]]
November was an average month in terms of activity, featuring eleven storms, of which six were named. The month also includes another unofficial cyclone named [[Storm Blas|Blas]] which formed in the [[Mediterranean tropical-like cyclone|Mediterranean Sea]] near [[Spain]]. In the East Pacific, Tropical Storms [[2021 Pacific hurricane season#Tropical Storm Terry|Terry]] and [[2021 Pacific hurricane season#Tropical Storm Sandra|Sandra]] formed, with both of the storms being named simultaneously on November 7. The West Pacific only featured a super typhoon named [[2021 Pacific typhoon season#Typhoon Nyatoh|Nyatoh]] which developed near [[Guam]], ending the record-long streak without a major tropical cyclone worldwide since October 3. Nyatoh became the strongest cyclone of November, later crossing into December and dissipating. In the North Indian Ocean, three depressions classified as [[2021 North Indian Ocean cyclone season#Depression ARB 03|ARB 03]], [[2021 North Indian Ocean cyclone season#Depression BOB 05|BOB 05]] and [[2021 North Indian Ocean cyclone season#Depression BOB 06|BOB 06]] formed. BOB 05 caused [[2021 South India floods|severe flooding]] in Southern India and [[Sri Lanka]] which killed more than 40 people, with BOB 06 causing additional damages over the same places; the worst damages occurred in the [[Rayalaseema]] region of [[Andhra Pradesh]]. Additionally, a tropical low formed in the Southern Hemisphere which began the [[2021–22 Australian region cyclone season]]. Later, another low formed which was then named ''Paddy''. Following Paddy, a few more depressions formed but dissipated a few days later. At the end of the month, [[2021–22 Australian region cyclone season#Tropical Cyclone Teratai|Tropical Cyclone Teratai]] formed south of [[Java]] but struggled to develop due to the lack of outflow. It then re-strengthened back into a tropical storm before weakening again and dissipating.

===December===
[[File:Rai 2021-12-16 0159Z.jpg|thumb|[[Typhoon Rai]]]]
December was slightly inactive, featuring nine storms, with five of them being named. The month started off with the formation of [[Cyclone Jawad]] which formed in the North Indian Ocean. However, Jawad rapidly weakened due to wind shear shortly after being named, and degenerated into a low-pressure area before it could make landfall over [[West Bengal]]. The Western Pacific featured a tropical depression classified as ''29W'' and a deadly and destructive typhoon, [[Typhoon Rai]]. Rai formed east of [[Palau]] before rapidly intensifying into a Category 5 super typhoon. It then made multiple landfalls on the [[Philippines]] causing serious damage. Rai then entered the [[South China Sea]], re-strengthening into a Category 5 super typhoon east of [[Vietnam]] before dissipating near [[Hong Kong]]. Rai became the first Category 5 super typhoon since [[Typhoon Nock-ten|Nock-ten]] to form in the month on December. It was also the third Category 5 super typhoon recorded in the South China Sea, behind [[Typhoon Pamela (1954)|Pamela]] in [[1954 Pacific typhoon season|1954]] and [[Typhoon Rammasun|Rammasun]] in [[2014 Pacific typhoon season|2014]]. On the other hand, ''29W'' formed near the equator before making landfall on [[Peninsular Malaysia]], [[December 2021 Malaysian floods|flooding]] some states within [[Malaysia]]. The Southern Hemisphere was inactive, only featuring three tropical lows and two cyclones named [[Cyclone Ruby|Ruby]] and [[2021–22 Australian region cyclone season#Tropical Cyclone Seth|Seth]]. Ruby intensified into a Category 2 tropical cyclone on the Australian scale and entered the South Pacific basin, making it the first storm in the basin. Ruby then made landfall on the French overseas island of [[New Caledonia]]. [[2021–22 Australian region cyclone season#Tropical Cyclone Seth|Seth]], on the other hand, first originated in the [[Arafura Sea]]. It then wandered around the northern regions of Australia before being named in the [[Solomon Sea]]. The Southern Atlantic featured its third named storm of the year, [[Subtropical Storm Ubá]].

There are a total of nine [[tropical cyclone basins]], seven are seasonal and two are non-seasonal, thus all seven basins except the [[Mediterranean tropical-like cyclone|Mediterranean]] and [[South Atlantic tropical cyclone|South Atlantic]] are active. In this table, data from all these basins are added. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident).<ref name="Tropical Cyclone Heat Potential Seven Basins">{{cite web |title=Tropical Cyclone Heat Potential Seven Basins |url=https://www.aoml.noaa.gov/phod/cyclone/data/seven.php |publisher=NOAA |access-date=20 October 2021 |archive-date=12 May 2021 |archive-url=https://web.archive.org/web/20210512200540/https://www.aoml.noaa.gov/phod/cyclone/data/seven.php |url-status=live}}</ref>
