Frost risk by date in Greeleyville
Half of springs at Kingstree, SC see their last 32°F night by March 29; only one in ten is past it by March 12, and one in ten still has one after April 11. Planting tender crops after April 3 leaves a 30% risk of a frost on them, after April 6 20%, and after April 11 10%. The 13 days between the even-odds date and the one-in-ten date is the narrowest of the 105 South Carolina stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 6 in half of years, as early as October 23 one year in ten, and holds off past November 23 one year in ten. A hard freeze of 28°F follows 10 days later, around November 16; in spring the one-in-ten date for 28°F is April 1, 10 days before the 32°F one. The freeze-free season lasts 223 days in a typical year, shorter than at 70% of the 105 South Carolina stations; it reaches 246 days one year in ten and falls short of 203 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 9 days longer, to about April 7, and return around October 28. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 76%.
