Frost risk by date in Social Circle
Half of springs at Covington, GA see their last 32°F night by March 22; only one in ten is past it by February 26, and one in ten still has one after April 6. Planting tender crops after March 30 leaves a 30% risk of a frost on them, after April 2 20%, and after April 6 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 83% of the 127 Georgia stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 14 in half of years, as early as November 1 one year in ten, and holds off past December 2 one year in ten. A hard freeze of 28°F follows 14 days later, around November 28; in spring the one-in-ten date for 28°F is March 27, 10 days before the 32°F one. The freeze-free season lasts 238 days in a typical year, longer than at 54% of the 127 Georgia stations; it reaches 267 days one year in ten and falls short of 214 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 99% of winters and 16°F in 51%.
