Frost risk by date in Ashland

Half of springs at Ashland, MS see their last 32°F night by March 29; only one in ten is past it by March 6, and one in ten still has one after April 15. Planting tender crops after April 4 leaves a 30% risk of a frost on them, after April 8 20%, and after April 15 10%. The 17 days between the even-odds date and the one-in-ten date is narrower than at 71% of the 96 Mississippi stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 6 in half of years, as early as October 22 one year in ten, and holds off past November 25 one year in ten. A hard freeze of 28°F follows 14 days later, around November 20; in spring the one-in-ten date for 28°F is April 3, 12 days before the 32°F one. The freeze-free season lasts 224 days in a typical year, shorter than at 76% of the 96 Mississippi stations; it reaches 251 days one year in ten and falls short of 200 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 10 days longer, to about April 8, and return around October 27. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 78%.
