Frost risk by date in Rising Fawn

Half of springs at Chickamauga 2 SW, GA see their last 32°F night by March 25; only one in ten is past it by March 4, and one in ten still has one after April 11. Planting tender crops after April 1 leaves a 30% risk of a frost on them, after April 5 20%, and after April 11 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 9 in half of years, as early as October 28 one year in ten, and holds off past December 1 one year in ten. A hard freeze of 28°F follows 16 days later, around November 25; in spring the one-in-ten date for 28°F is March 31, 11 days before the 32°F one. The freeze-free season lasts 232 days in a typical year, shorter than at 56% of the 127 Georgia stations; it reaches 259 days one year in ten and falls short of 207 one year in ten. On average 76 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 7, and return around October 30. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 66%.
