Frost risk by date in Whiteville

Half of springs at Whiteville 7 NW, NC see their last 32°F night by March 29; only one in ten is past it by March 8, 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 6 in half of years, as early as October 25 one year in ten, and holds off past November 23 one year in ten. A hard freeze of 28°F follows 11 days later, around November 17; in spring the one-in-ten date for 28°F is April 1, 11 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 204 one year in ten. On average 59 nights a year drop to 32°F or below. Nights of 36°F, when frost can still settle on leaves in low, open spots, continue 10 days longer, to about April 8, and return around October 30. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 60%.
