Frost risk by date in Pelzer
Half of springs at W Pelzer, SC see their last 32°F night by April 1; only one in ten is past it by March 14, and one in ten still has one after April 17. Planting tender crops after April 7 leaves a 30% risk of a frost on them, after April 11 20%, and after April 17 10%. The 16 days between the even-odds date and the one-in-ten date is narrower than at 44% of the 105 South Carolina stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 4 in half of years, as early as October 22 one year in ten, and holds off past November 20 one year in ten. A hard freeze of 28°F follows 12 days later, around November 16; in spring the one-in-ten date for 28°F is April 5, 12 days before the 32°F one. The freeze-free season lasts 219 days in a typical year, shorter than at 76% of the 105 South Carolina stations; it reaches 242 days one year in ten and falls short of 197 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 79%.
