Frost risk by date in Camp Lejeune
Half of springs at New River Mcaf, NC see their last 32°F night by March 23; only one in ten is past it by March 2, and one in ten still has one after April 7. Planting tender crops after March 31 leaves a 30% risk of a frost on them, after April 3 20%, and after April 7 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 16 in half of years, as early as November 1 one year in ten, and holds off past December 7 one year in ten. A hard freeze of 28°F follows 15 days later, around December 1; in spring the one-in-ten date for 28°F is March 29, 9 days before the 32°F one. The freeze-free season lasts 240 days in a typical year, longer than at 94% of the 173 North Carolina stations; it reaches 268 days one year in ten and falls short of 216 one year in ten. On average 43 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 2, and return around November 5. Nights of 24°F, cold enough to damage hardier plants, come in 99% of winters and 16°F in 41%.
