Frost risk by date in Barnardsville

Half of springs at N Fk 2, NC see their last 32°F night by April 5; only one in ten is past it by March 20, and one in ten still has one after April 22. Planting tender crops after April 11 leaves a 30% risk of a frost on them, after April 16 20%, and after April 22 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 October 31 in half of years, as early as October 16 one year in ten, and holds off past November 16 one year in ten. A hard freeze of 28°F follows 10 days later, around November 10; in spring the one-in-ten date for 28°F is April 7, 15 days before the 32°F one. The freeze-free season lasts 206 days in a typical year, shorter than at 66% of the 173 North Carolina stations; it reaches 228 days one year in ten and falls short of 187 one year in ten. On average 64 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 16 days longer, to about April 21, and return around October 21. Severe cold of 16°F or below comes in 97% of winters, usually between December 28 and February 9.
