Frost risk by date in Dudley

Half of springs at Goldsboro 4 SE, NC see their last 32°F night by March 15; only one in ten is past it by February 23, and one in ten still has one after April 1. Planting tender crops after March 23 leaves a 30% risk of a frost on them, after March 28 20%, and after April 1 10%. The 17 days between the even-odds date and the one-in-ten date is wider than at 65% of the 173 North Carolina stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 18 in half of years, as early as November 2 one year in ten, and holds off past December 7 one year in ten. A hard freeze of 28°F follows 16 days later, around December 4; in spring the one-in-ten date for 28°F is March 20, 12 days before the 32°F one. The freeze-free season lasts 250 days in a typical year, longer than at 98% of the 173 North Carolina stations; it reaches 278 days one year in ten and falls short of 227 one year in ten. On average 42 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 14 days longer, to about March 29, and return around November 6. Nights of 24°F, cold enough to damage hardier plants, come in 97% of winters and 16°F in 41%.
