Frost risk by date in Dora

Half of springs at Jasper, AL see their last 32°F night by March 30; only one in ten is past it by March 10, and one in ten still has one after April 16. Planting tender crops after April 5 leaves a 30% risk of a frost on them, after April 10 20%, and after April 16 10%. The 17 days between the even-odds date and the one-in-ten date is narrower than at 64% of the 115 Alabama stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 4 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 11 days later, around November 15; in spring the one-in-ten date for 28°F is April 3, 13 days before the 32°F one. The freeze-free season lasts 220 days in a typical year, shorter than at 71% of the 115 Alabama stations; it reaches 244 days one year in ten and falls short of 197 one year in ten. On average 73 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 12 days longer, to about April 11, and return around October 25. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 84%.
