Frost risk by date in Hoboken

Half of springs at Waycross 4 NE, GA see their last 32°F night by March 15; only one in ten is past it by February 20, and one in ten still has one after April 3. Planting tender crops after March 24 leaves a 30% risk of a frost on them, after March 29 20%, and after April 3 10%. The 19 days between the even-odds date and the one-in-ten date is wider than at 60% of the 127 Georgia stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 17 in half of years, as early as October 31 one year in ten, and holds off past December 6 one year in ten. A hard freeze of 28°F follows 14 days later, around December 1; in spring the one-in-ten date for 28°F is March 23, 11 days before the 32°F one. The freeze-free season lasts 246 days in a typical year, longer than at 63% of the 127 Georgia stations; it reaches 278 days one year in ten and falls short of 220 one year in ten. On average 41 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 16 days longer, to about March 31, and return around November 6. Nights of 24°F, cold enough to damage hardier plants, come in 96% of winters and 16°F in 26%.
