Frost risk by date in Comer
Half of springs at Danielsville, GA see their last 32°F night by March 29; only one in ten is past it by March 8, 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 8 20%, and after April 14 10%. The 16 days between the even-odds date and the one-in-ten date is narrower than at 70% of the 127 Georgia stations behind this site's ZIP pages.
