Frost risk by date in Salisbury
Half of springs at Salisbury, NC see their last 32°F night by April 6; only one in ten is past it by March 21, and one in ten still has one after April 27. Planting tender crops after April 13 leaves a 30% risk of a frost on them, after April 18 20%, and after April 27 10%. The 21 days between the even-odds date and the one-in-ten date is wider than at 98% of the 173 North Carolina stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
In fall the first 32°F night comes by October 30 in half of years, as early as October 19 one year in ten, and holds off past November 10 one year in ten. A hard freeze of 28°F follows 9 days later, around November 8; in spring the one-in-ten date for 28°F is April 10, 17 days before the 32°F one. The freeze-free season lasts 208 days in a typical year, shorter than at 62% of the 173 North Carolina stations; it reaches 226 days one year in ten and falls short of 184 one year in ten. On average 71 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 12 days longer, to about April 18, and return around October 22. Severe cold of 16°F or below comes in 96% of winters, usually between December 30 and February 10.
