Frost risk by date in ZIP 30627
Half of springs at Lexington, GA see their last 32°F night by March 31; only one in ten is past it by March 14, and one in ten still has one after April 13. Planting tender crops after April 5 leaves a 30% risk of a frost on them, after April 8 20%, and after April 13 10%. The 13 days between the even-odds date and the one-in-ten date measure how much the end of the frost season moves from year to year.
In fall the first 32°F night comes by November 6 in half of years, as early as October 26 one year in ten, and holds off past November 21 one year in ten. A hard freeze of 28°F follows 11 days later, around November 17; in spring the one-in-ten date for 28°F is April 3, 10 days before the 32°F one. The freeze-free season lasts 221 days in a typical year; it reaches 243 days one year in ten and falls short of 200 one year in ten. On average 58 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 13, and return around October 28. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 75%.
