Frost risk by date in Angola

Half of springs at St Francisville 1 NE, LA see their last 32°F night by March 2; only one in ten is past it by January 31, and one in ten still has one after March 29. Planting tender crops after March 14 leaves a 30% risk of a frost on them, after March 19 20%, and after March 29 10%. The 27 days between the even-odds date and the one-in-ten date is wider than at 81% 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 24 in half of years, as early as November 5 one year in ten, and holds off past December 16 one year in ten. A hard freeze of 28°F follows 16 days later, around December 10; in spring the one-in-ten date for 28°F is March 14, 15 days before the 32°F one. The freeze-free season lasts 268 days in a typical year, longer than at 50% of the 88 Louisiana stations; it reaches 304 days one year in ten and falls short of 235 one year in ten. On average 28 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 22 days longer, to about March 24, and return around November 12. Nights of 24°F, cold enough to damage hardier plants, come in 85% of winters and 16°F in 15%.
