Frost risk by date in Ringgold

Half of springs at Chickamauga Pk Larc, GA see their last 32°F night by April 6; only one in ten is past it by March 20, and one in ten still has one after April 23. Planting tender crops after April 12 leaves a 30% risk of a frost on them, after April 17 20%, and after April 23 10%. The 17 days between the even-odds date and the one-in-ten date is narrower than at 56% of the 127 Georgia stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 30 in half of years, as early as October 17 one year in ten, and holds off past November 11 one year in ten. A hard freeze of 28°F follows 7 days later, around November 6; in spring the one-in-ten date for 28°F is April 10, 13 days before the 32°F one. The freeze-free season lasts 205 days in a typical year, shorter than at 91% of the 127 Georgia stations; it reaches 226 days one year in ten and falls short of 185 one year in ten. On average 84 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 19, and return around October 21. Severe cold of 16°F or below comes in 95% of winters, usually between December 27 and February 8.
