Frost risk by date in Randleman
Half of springs at Randleman, NC see their last 32°F night by March 29; only one in ten is past it by March 13, and one in ten still has one after April 13. Planting tender crops after April 3 leaves a 30% risk of a frost on them, after April 7 20%, and after April 13 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 57% of the 173 North Carolina stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 6 in half of years, as early as October 25 one year in ten, and holds off past November 24 one year in ten. A hard freeze of 28°F follows 13 days later, around November 19; in spring the one-in-ten date for 28°F is April 1, 12 days before the 32°F one. The freeze-free season lasts 224 days in a typical year, longer than at 65% of the 173 North Carolina stations; it reaches 247 days one year in ten and falls short of 203 one year in ten.
