Frost Dates for 36351 — New Brockton, Alabama

Half of springs at Enterprise 4 W, AL see their last 32°F night by March 9; only one in ten is past it by February 14, and one in ten still has one after March 31. Planting tender crops after March 17 leaves a 30% risk of a frost on them, after March 22 20%, and after March 31 10%. The 22 days between the even-odds date and the one-in-ten date is wider than at 95% of the 115 Alabama stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
