Frost risk by date in Longville
Half of springs at De Ridder, LA see their last 32°F night by March 1; only one in ten is past it by February 2, and one in ten still has one after March 25. Planting tender crops after March 10 leaves a 30% risk of a frost on them, after March 16 20%, and after March 25 10%. The 24 days between the even-odds date and the one-in-ten date is wider than at 63% of the 88 Louisiana 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 25 in half of years, as early as November 8 one year in ten, and holds off past December 13 one year in ten. A hard freeze of 28°F follows 12 days later, around December 7; in spring the one-in-ten date for 28°F is March 10, 15 days before the 32°F one. The freeze-free season lasts 269 days in a typical year, longer than at 55% of the 88 Louisiana stations; it reaches 301 days one year in ten and falls short of 237 one year in ten. On average 26 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 18, and return around November 13. Nights of 24°F, cold enough to damage hardier plants, come in 81% of winters and 16°F in 12%.
