The majority of Georgia is primarily a humid subtropical climate. 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 region of Georgia is subtropical depends on the latitude, its proximity to the Atlantic Ocean or Gulf of Mexico and the elevation. The latter factor is felt chiefly in the mountainous areas of the northern part of the state, which are farther away from the ocean and can be 4500 feet (1350 m) above sea level. The USDA Plant hardiness zones for Georgia range from zone 6b (no colder than −5 °F (−21 °C) ) in the Blue Ridge Mountains mountains to zone 8b (no colder than 15 °F (−9 °C) ) along the Atlantic coast and Florida border.

 

The highest temperature ever recorded is 112 °F (44.4 °C) at Louisville on July 24, 1952, while the lowest is −17 °F (−27.2 °C) at northern Floyd County on January 27, 1940. Georgia is one of the leading states in frequency of tornadoes, though they rarely are stronger than F1. A tornado hit downtown Atlanta on March 14, 2008, causing moderate to severe damage. With a coastline on the Atlantic Ocean, Georgia is also vulnerable to hurricanes, although direct hurricane strikes were rare during the 20th century. Georgia often is affected by hurricanes that strike the Florida panhandle, weaken over land, and bring strong tropical storm winds and heavy rain to the interior, as well as hurricanes that come close to the Georgia coastline, brushing the coast on their way north.
