Frost risk by date in Chattahoochee

Half of springs at Bainbridge International Paper, GA see their last 32°F night by March 14; only one in ten is past it by February 21, and one in ten still has one after April 3. Planting tender crops after March 22 leaves a 30% risk of a frost on them, after March 28 20%, and after April 3 10%. The 20 days between the even-odds date and the one-in-ten date is narrower than at 79% of the 101 Florida stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 17 in half of years, as early as November 3 one year in ten, and holds off past December 9 one year in ten. A hard freeze of 28°F follows 15 days later, around December 2; in spring the one-in-ten date for 28°F is March 21, 13 days before the 32°F one. The freeze-free season lasts 250 days in a typical year, shorter than at 98% of the 102 Florida stations; it reaches 280 days one year in ten and falls short of 221 one year in ten. On average 39 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 16 days longer, to about March 30, and return around November 7. Nights of 24°F, cold enough to damage hardier plants, come in 95% of winters and 16°F in 31%.
