Frost risk by date in Buras
In the 76% of winters that bring a 32°F night, half of winters at Buras, LA see their last 32°F night by January 25; only one in ten is past it by December 31, and one in ten still has one after February 21. Counting the winters with no freeze at all, the risk of a 32°F night after February 21 is under 8% and after January 25 38%. 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 January 4 in half of years, as early as December 13 one year in ten, and holds off past January 29 one year in ten. A hard freeze of 28°F is less common: it came in 37% of winters. On average 3 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 11 days longer, to about February 5, and return around December 25. A 24°F night is unusual: 11% of winters had one.
