Frost risk by date in Claxton
Half of springs at Glennville 3NW, GA see their last 32°F night by March 9; only one in ten is past it by February 16, and one in ten still has one after March 30. Planting tender crops after March 18 leaves a 30% risk of a frost on them, after March 23 20%, and after March 30 10%. The 21 days between the even-odds date and the one-in-ten date is wider than at 83% of the 127 Georgia stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
In fall the first 32°F night comes by November 24 in half of years, as early as November 5 one year in ten, and holds off past December 15 one year in ten. A hard freeze of 28°F follows 15 days later, around December 9; in spring the one-in-ten date for 28°F is March 17, 13 days before the 32°F one. The freeze-free season lasts 258 days in a typical year, longer than at 84% of the 127 Georgia stations; it reaches 287 days one year in ten and falls short of 231 one year in ten. On average 30 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 14 days longer, to about March 23, and return around November 9. Nights of 24°F, cold enough to damage hardier plants, come in 90% of winters and 16°F in 17%.
