Frost risk by date in Branchville

Half of springs at Bamberg, SC see their last 32°F night by March 18; only one in ten is past it by February 26, and one in ten still has one after April 4. Planting tender crops after March 26 leaves a 30% risk of a frost on them, after March 30 20%, and after April 4 10%. The 17 days between the even-odds date and the one-in-ten date is wider than at 57% of the 105 South Carolina stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 12 in half of years, as early as November 1 one year in ten, and holds off past December 2 one year in ten. A hard freeze of 28°F follows 14 days later, around November 26; in spring the one-in-ten date for 28°F is March 25, 10 days before the 32°F one. The freeze-free season lasts 240 days in a typical year, longer than at 72% of the 105 South Carolina stations; it reaches 266 days one year in ten and falls short of 218 one year in ten. On average 38 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 13 days longer, to about March 31, and return around November 3. Nights of 24°F, cold enough to damage hardier plants, come in 98% of winters and 16°F in 37%.
