How to read Atlanta climate normals
What a climate normal is, and what it is not.
A normal is the average of thirty years of daily observations at one station — here Atlanta Dekalb Peachtree Ap, 14.4 km from the centre of Atlanta. It describes a typical year, so any single year will run warmer, cooler, wetter or drier. Readings taken at an airport on the edge of town usually sit a degree or two below a dense downtown on summer nights. Atlanta sees about 39.1 days a year at or above 90°F.
