Frost risk by date in West Point
Half of springs at State Univ, MS see their last 32°F night by March 23; only one in ten is past it by February 28, and one in ten still has one after April 13. Planting tender crops after April 1 leaves a 30% risk of a frost on them, after April 5 20%, and after April 13 10%. The 21 days between the even-odds date and the one-in-ten date is wider than at 73% of the 96 Mississippi stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
In fall the first 32°F night comes by November 8 in half of years, as early as October 27 one year in ten, and holds off past December 1 one year in ten. A hard freeze of 28°F follows 14 days later, around November 22; in spring the one-in-ten date for 28°F is March 30, 14 days before the 32°F one. The freeze-free season lasts 233 days in a typical year, shorter than at 63% of the 96 Mississippi stations; it reaches 261 days one year in ten and falls short of 207 one year in ten. On average 58 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 5, and return around October 31. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 67%.
