Frost risk by date in Buckhead

Half of springs at Siloam 3N, GA see their last 32°F night by March 27; only one in ten is past it by March 6, and one in ten still has one after April 13. Planting tender crops after April 3 leaves a 30% risk of a frost on them, after April 7 20%, and after April 13 10%. The 17 days between the even-odds date and the one-in-ten date is narrower than at 56% of the 127 Georgia stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 8 in half of years, as early as October 25 one year in ten, and holds off past November 26 one year in ten. A hard freeze of 28°F follows 15 days later, around November 23; in spring the one-in-ten date for 28°F is March 31, 13 days before the 32°F one. The freeze-free season lasts 226 days in a typical year, shorter than at 65% of the 127 Georgia stations; it reaches 255 days one year in ten and falls short of 205 one year in ten. On average 59 nights a year drop to 32°F or below. Nights of 36°F, when frost can still settle on leaves in low, open spots, continue 13 days longer, to about April 9, and return around October 30. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 65%.
