Frost risk by date in Landrum
Half of springs at Tryon, NC see their last 32°F night by March 27; only one in ten is past it by March 9, and one in ten still has one after April 14. Planting tender crops after April 1 leaves a 30% risk of a frost on them, after April 6 20%, and after April 14 10%. The 18 days between the even-odds date and the one-in-ten date is wider than at 77% 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 October 29 one year in ten, and holds off past December 1 one year in ten. A hard freeze of 28°F follows 15 days later, around November 27; in spring the one-in-ten date for 28°F is March 31, 14 days before the 32°F one.
