Frost risk by date in Robins Afb
Half of springs at Warner Robins, GA see their last 32°F night by March 11; only one in ten is past it by February 15, and one in ten still has one after March 31. Planting tender crops after March 20 leaves a 30% risk of a frost on them, after March 25 20%, and after March 31 10%. The 20 days between the even-odds date and the one-in-ten date is wider than at 70% of the 127 Georgia stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 19 in half of years, as early as November 4 one year in ten, and holds off past December 9 one year in ten. A hard freeze of 28°F follows 15 days later, around December 4; in spring the one-in-ten date for 28°F is March 20, 11 days before the 32°F one. The freeze-free season lasts 256 days in a typical year, longer than at 79% of the 127 Georgia stations; it reaches 285 days one year in ten and falls short of 229 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 93% of winters and 16°F in 28%.
