Frost risk by date in Villa Rica
Half of springs at Carrollton, GA see their last 32°F night by March 28; only one in ten is past it by March 7, and one in ten still has one after April 12. Planting tender crops after April 2 leaves a 30% risk of a frost on them, after April 6 20%, and after April 12 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 83% of the 127 Georgia stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 5 in half of years, as early as October 23 one year in ten, and holds off past November 22 one year in ten. A hard freeze of 28°F follows 11 days later, around November 16; in spring the one-in-ten date for 28°F is March 31, 12 days before the 32°F one. The freeze-free season lasts 222 days in a typical year, shorter than at 70% of the 127 Georgia stations; it reaches 248 days one year in ten and falls short of 202 one year in ten. On average 65 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 11 days longer, to about April 8, and return around October 26. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 78%.
