Frost risk by date in Vienna
Half of springs at Cordele, GA see their last 32°F night by March 13; only one in ten is past it by February 20, and one in ten still has one after March 31. Planting tender crops after March 20 leaves a 30% risk of a frost on them, after March 25 20%, and after March 31 10%. The 18 days between the even-odds date and the one-in-ten date is narrower than at 41% of the 127 Georgia stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 14 in half of years, as early as November 1 one year in ten, and holds off past December 4 one year in ten. A hard freeze of 28°F follows 15 days later, around November 29; in spring the one-in-ten date for 28°F is March 19, 12 days before the 32°F one. The freeze-free season lasts 248 days in a typical year, longer than at 65% of the 127 Georgia stations; it reaches 278 days one year in ten and falls short of 223 one year in ten. On average 31 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 15 days longer, to about March 28, and return around November 4. Nights of 24°F, cold enough to damage hardier plants, come in 95% of winters and 16°F in 34%.
