Frost risk by date in Jackson Springs

Half of springs at Jackson Springs 5 WNW, NC see their last 32°F night by March 25; only one in ten is past it by March 6, and one in ten still has one after April 10. Planting tender crops after April 2 leaves a 30% risk of a frost on them, after April 5 20%, and after April 10 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 14 in half of years, as early as October 30 one year in ten, and holds off past December 4 one year in ten. A hard freeze of 28°F follows 15 days later, around November 29; in spring the one-in-ten date for 28°F is April 1, 9 days before the 32°F one. The freeze-free season lasts 235 days in a typical year, longer than at 87% of the 173 North Carolina stations; it reaches 260 days one year in ten and falls short of 212 one year in ten. On average 58 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 11 days longer, to about April 5, and return around November 2. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 70%.
