Frost risk by date in Beech Island

Half of springs at Augusta Bush Field Airport, GA see their last 32°F night by March 23; only one in ten is past it by February 28, and one in ten still has one after April 9. Planting tender crops after March 31 leaves a 30% risk of a frost on them, after April 3 20%, and after April 9 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 9 in half of years, as early as October 28 one year in ten, and holds off past November 27 one year in ten. A hard freeze of 28°F follows 15 days later, around November 24; in spring the one-in-ten date for 28°F is March 28, 12 days before the 32°F one. The freeze-free season lasts 232 days in a typical year, longer than at 51% of the 105 South Carolina stations; it reaches 258 days one year in ten and falls short of 210 one year in ten. On average 51 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 April 5, and return around November 1. Nights of 24°F, cold enough to damage hardier plants, come in 99% of winters and 16°F in 46%.
