Frost risk by date in Springville
Half of springs at Oneonta, AL see their last 32°F night by March 26; only one in ten is past it by March 2, and one in ten still has one after April 12. Planting tender crops after April 2 leaves a 30% risk of a frost on them, after April 6 20%, and after April 12 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 10 in half of years, as early as October 26 one year in ten, and holds off past November 30 one year in ten. A hard freeze of 28°F follows 14 days later, around November 24; in spring the one-in-ten date for 28°F is March 29, 14 days before the 32°F one. The freeze-free season lasts 230 days in a typical year, shorter than at 52% of the 115 Alabama stations; it reaches 256 days one year in ten and falls short of 206 one year in ten. On average 65 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 11 days longer, to about April 6, and return around October 30. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 73%.
