Frost risk by date in Hackleburg
Half of springs at Haleyville, AL see their last 32°F night by March 29; only one in ten is past it by March 5, 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 18 days between the even-odds date and the one-in-ten date is narrower than at 46% of the 115 Alabama 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 25 one year in ten, and holds off past November 28 one year in ten. A hard freeze of 28°F follows 12 days later, around November 21; 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 228 days in a typical year, shorter than at 58% of the 115 Alabama stations; it reaches 254 days one year in ten and falls short of 201 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 83%.
