Frost risk by date in Aliceville
Half of springs at Aliceville, AL see their last 32°F night by March 24; only one in ten is past it by March 1, and one in ten still has one after April 13. Planting tender crops after April 2 leaves a 30% risk of a frost on them, after April 6 20%, and after April 13 10%. The 20 days between the even-odds date and the one-in-ten date is wider than at 70% of the 115 Alabama stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 8 in half of years, as early as October 26 one year in ten, and holds off past November 27 one year in ten. A hard freeze of 28°F follows 12 days later, around November 20; in spring the one-in-ten date for 28°F is March 29, 15 days before the 32°F one.
