Frost risk by date in Aulander
Half of springs at Lewiston, NC see their last 32°F night by March 29; only one in ten is past it by March 12, and one in ten still has one after April 12. Planting tender crops after April 4 leaves a 30% risk of a frost on them, after April 7 20%, and after April 12 10%. The 14 days between the even-odds date and the one-in-ten date is narrower than at 79% of the 173 North Carolina stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 7 in half of years, as early as October 27 one year in ten, and holds off past November 25 one year in ten.
