Frost risk by date in Greer
Half of springs at Greer, SC see their last 32°F night by March 28; only one in ten is past it by March 10, and one in ten still has one after April 14. Planting tender crops after April 4 leaves a 30% risk of a frost on them, after April 7 20%, and after April 14 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.
