Frost risk by date in Weldon
Half of springs at Roanoke Rapids, NC see their last 32°F night by March 31; only one in ten is past it by March 15, and one in ten still has one after April 16. Planting tender crops after April 6 leaves a 30% risk of a frost on them, after April 10 20%, and after April 16 10%. The 16 days between the even-odds date and the one-in-ten date is narrower than at 35% of the 173 North Carolina 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 28 one year in ten, and holds off past November 25 one year in ten. A hard freeze of 28°F follows 13 days later, around November 22; in spring the one-in-ten date for 28°F is April 4, 12 days before the 32°F one.
