Worldwide climate classifications

The climate of Georgia is typical of a humid subtropical climate with mild winters and hot summers. The Chattahoochee River divides Georgia into separate climatic regions with mountain region to the northwest being colder than the rest of Georgia, the average temperature for that region in January and July being 39°F (4°C) and 78°F (26°C) respectively.

General climatology

The average daily temperature of Atlanta, Georgia

The majority of Georgia is primarily a humid subtropical climate tempered somewhat by occasional polar air masses in the winter. Hot and humid summers are typical, except at the highest elevations. The entire state, including the north Georgia mountains, receives moderate to heavy precipitation, which varies from 45 inches (1143 mm) in central Georgia to approximately 75 inches (1905 mm) around the Northeast part of the state. The degree to which the weather of a certain area of Georgia is subtropical depends not just on the latitude, but also on how close it is to the Atlantic Ocean or Gulf of Mexico and the altitude. This is especially true in the mountainous areas in the northern part of the state, which are further away from ocean waters and can be up to 4500 feet (1350 m) or higher above sea level.

The areas near the Florida/Georgia border, extending from the entire Georgia coastline west to the Florida panhandle, experiences the most subtropical weather, similar to that of Florida: hot, humid summers with frequent afternoon thunderstorms and mild, somewhat drier winters. These areas experience snow much less frequently than other parts of Georgia. The Georgia Piedmont area is somewhat cooler in winter than the coastal areas. The Southern areas of the Piedmont may receive snow every other year, while areas close to the foothills get snow several times a year. This part of Georgia is especially vulnerable to ice storms. The mountains of Georgia have the coolest climate and most frequent snowfall in the state, although snowfall is less than any other part of the Appalachian Mountains.

In spite of having moderate weather compared to many other states, Georgia has occasional extreme weather. The highest temperature ever recorded is 112 °F (44.4 °C), while the lowest ever recorded is -17 °F (-27.2 °C). Georgia is one of the leading states in incidents of tornadoes. The areas closest to the Florida border get the same small F0 and F1 tornadoes associated with summer afternoon thunderstorms. However, it is very uncommon for tornadoes to become severe (over F3). As it is on the Atlantic coast, Georgia is also vulnerable to hurricanes, although the Georgia coastline only rarely experiences a direct hurricane strike. More common are hurricanes which strike the Florida panhandle, weaken over land, and bring strong tropical storm winds and heavy rain to the Georgia interior, as well as hurricanes that come close to the Georgia coastline, brushing the coast on their recurvature on the way up to hit the Carolinas.

In 2006 and 2007, however, Georgia has had severe droughts, especially in 2007. Temperatures over 100 degrees have been recorded.

Winter

Winter in Georgia most noticeably affects North and Central Georgia. The main winter weather hazards in those regions "freezing rain - or icing, heavy snow - which is 2 or more inches of snow falling in a 12 hour period, or 4 or more inches in a 24 hour period." The exception to this is the mountain areas of Fannin, Gilmer, Pickens, and other surrounding counties heavy snow is "3 inches or more of snow in a 12 hour period or 4 inches or more of snow in a 24 hour period". Watches for heavy snow are issued when a 50 percent or greater chance of 2 or more inches of snow falling in a 12 hour period, or 4 or more inches in a 24 hour period occurs. Again, the are exceptions in the counties listed previously. The criteria for the mountain counties is "3 inches or more of snow in a 12 hour period or 4 inches or more of snow in a 24 hour period".

Ice is another danger in the region. Watches are issued when there is a "50 percent or greater chance of significant and damaging accumulations of ice during freezing rain situations"; these watches are normally issued 12 to 48 hours in advance. A winter storm warning for an ice storm means that icy conditions are "occurring, imminent, or have a very high probability of occurring". These warnings are usually issued when there is an 80 percent or greater chance of meeting ice storm conditions.

Also in North and Central Georgia a Wind Chill Advisory is issued for wind chill index values of zero or below. A wind chill warning is issued whenever wind chill index values reach minus 15 degrees or lower. It is rare in Georgia for any portion of the state to have a blizzard. In fact, the last blizzard the state had was in March of 1993.

Winter in South Georgia, which lasts from December to January, is much more mild. Daytime highs range from approximately 50 degrees (around 10-15 C.) in the northernmost interior areas to the 60s and 70s (15-26 degrees C.) on the coast and in the extreme south.
