Frost risk by date in Inez

Half of springs at Victoria Regional Airport, TX see their last 32°F night by February 4; only one in ten is past it by December 30, and one in ten still has one after March 5. Planting tender crops after February 19 leaves a 30% risk of a frost on them, after February 26 20%, and after March 5 10%. The 29 days between the even-odds date and the one-in-ten date is wider than at 90% of the 339 Texas 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 December 9 in half of years, as early as November 18 one year in ten, and holds off past January 13 one year in ten. A hard freeze of 28°F follows 23 days later, around January 1; in spring the one-in-ten date for 28°F is February 21, 12 days before the 32°F one. The freeze-free season lasts 309 days in a typical year, longer than at 91% of the 339 Texas stations; it reaches 348 days one year in ten and falls short of 272 one year in ten. On average 7 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 February 26, and return around November 26. A 24°F night is unusual: 28% of winters had one.
