Frost risk by date in Dallas

Half of springs at Dallas 7 NE, GA see their last 32°F night by April 2; only one in ten is past it by March 15, and one in ten still has one after April 19. Planting tender crops after April 9 leaves a 30% risk of a frost on them, after April 13 20%, and after April 19 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 November 4 in half of years, as early as October 23 one year in ten, and holds off past November 20 one year in ten. A hard freeze of 28°F follows 13 days later, around November 17; in spring the one-in-ten date for 28°F is April 7, 12 days before the 32°F one. The freeze-free season lasts 218 days in a typical year, shorter than at 79% of the 127 Georgia stations; it reaches 244 days one year in ten and falls short of 196 one year in ten. On average 73 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 14 days longer, to about April 16, and return around October 26. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 83%.
