Frost risk by date in Rabun Gap

Half of springs at Mountain City 2 SW, GA see their last 32°F night by April 18; only one in ten is past it by April 2, and one in ten still has one after May 4. Planting tender crops after April 25 leaves a 30% risk of a frost on them, after April 29 20%, and after May 4 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.

In fall the first 32°F night comes by October 25 in half of years, as early as October 13 one year in ten, and holds off past November 7 one year in ten. A hard freeze of 28°F follows 11 days later, around November 5; in spring the one-in-ten date for 28°F is April 21, 13 days before the 32°F one. The freeze-free season lasts 191 days in a typical year, shorter than at 98% of the 127 Georgia stations; it reaches 214 days one year in ten and falls short of 170 one year in ten. On average 83 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 May 1, and return around October 17. Severe cold of 16°F or below comes in 99% of winters, usually between December 24 and February 23.
