Frost risk by date in Manchester

Half of springs at Talbotton, GA see their last 32°F night by April 1; only one in ten is past it by March 13, and one in ten still has one after April 16. Planting tender crops after April 7 leaves a 30% risk of a frost on them, after April 12 20%, and after April 16 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 3 in half of years, as early as October 22 one year in ten, and holds off past November 19 one year in ten. A hard freeze of 28°F follows 12 days later, around November 15; in spring the one-in-ten date for 28°F is April 2, 14 days before the 32°F one. The freeze-free season lasts 216 days in a typical year, shorter than at 82% of the 127 Georgia stations; it reaches 240 days one year in ten and falls short of 194 one year in ten. On average 54 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 14, and return around October 25. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 81%.
