What's Typical in North and Central Georgia?
an overview of the climatology of the area comprising the northern half of the state

Variance in the climate across north Georgia is largely a function of terrain. Most of the northern half of the state is made up of rolling hills with elevation ranging from about 400 feet across the midstate to generally between 800 and 1100 feet across the rest of the area. The climate of this region is fairly uniform. A notable exception is in the northeast corner of the state occupied by the Appalachian Mountains. Although average elevation in the "Northeast Georgia Mountains" is less than 2000 feet, there are mountains that reach elevations between 4000 and 5000 feet. The climate here differs significantly from the rest of north Georgia.
