Frost risk by date in Pisgah
Half of springs at Scottsboro 2 NE, AL see their last 32°F night by April 2; only one in ten is past it by March 18, and one in ten still has one after April 19. Planting tender crops after April 9 leaves a 30% risk of a frost on them, after April 13 20%, and after April 19 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 October 30 in half of years, as early as October 18 one year in ten, and holds off past November 12 one year in ten. A hard freeze of 28°F follows 9 days later, around November 8; in spring the one-in-ten date for 28°F is April 7, 12 days before the 32°F one. The freeze-free season lasts 210 days in a typical year, shorter than at 85% of the 115 Alabama stations; it reaches 232 days one year in ten and falls short of 188 one year in ten. On average 72 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 15, and return around October 23. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 89%.
