Frost risk by date in Many

Half of springs at Many, LA see their last 32°F night by March 20; only one in ten is past it by February 26, and one in ten still has one after April 9. Planting tender crops after March 29 leaves a 30% risk of a frost on them, after April 2 20%, and after April 9 10%. The 20 days between the even-odds date and the one-in-ten date is narrower than at 72% of the 88 Louisiana stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 9 in half of years, as early as October 26 one year in ten, and holds off past December 4 one year in ten. A hard freeze of 28°F follows 15 days later, around November 24; in spring the one-in-ten date for 28°F is March 27, 13 days before the 32°F one. The freeze-free season lasts 236 days in a typical year, shorter than at 94% of the 88 Louisiana stations; it reaches 265 days one year in ten and falls short of 208 one year in ten. On average 39 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 3, and return around November 1. Nights of 24°F, cold enough to damage hardier plants, come in 97% of winters and 16°F in 32%.
