Frost Dates for 39111 — Magee, Mississippi

Half of springs at D'Lo 2 SW, MS see their last 32°F night by March 10; only one in ten is past it by February 17, and one in ten still has one after April 1. Planting tender crops after March 19 leaves a 30% risk of a frost on them, after March 25 20%, and after April 1 10%. The 22 days between the even-odds date and the one-in-ten date is wider than at 85% 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 16 in half of years, as early as October 31 one year in ten, and holds off past December 7 one year in ten. A hard freeze of 28°F follows 15 days later, around December 1; in spring the one-in-ten date for 28°F is March 16, 16 days before the 32°F one. The freeze-free season lasts 252 days in a typical year, longer than at 78% of the 96 Mississippi stations; it reaches 284 days one year in ten and falls short of 224 one year in ten. On average 59 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 17 days longer, to about March 27, and return around November 3. Nights of 24°F, cold enough to damage hardier plants, come in 91% of winters and 16°F in 22%.
