Frost risk by date in Juliette
Half of springs at Monticello, GA see their last 32°F night by April 4; only one in ten is past it by March 18, and one in ten still has one after April 20. Planting tender crops after April 11 leaves a 30% risk of a frost on them, after April 15 20%, and after April 20 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 November 1 in half of years, as early as October 20 one year in ten, and holds off past November 16 one year in ten. A hard freeze of 28°F follows 10 days later, around November 11; in spring the one-in-ten date for 28°F is April 7, 13 days before the 32°F one. The freeze-free season lasts 211 days in a typical year, shorter than at 88% of the 127 Georgia stations; it reaches 233 days one year in ten and falls short of 191 one year in ten. On average 71 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 17, and return around October 23. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 89%.
