Frost risk by date in Cuero
Half of springs at Cuero, TX see their last 32°F night by March 2; only one in ten is past it by February 2, and one in ten still has one after March 24. Planting tender crops after March 11 leaves a 30% risk of a frost on them, after March 17 20%, and after March 24 10%. The 22 days between the even-odds date and the one-in-ten date is wider than at 63% 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 November 27 in half of years, as early as November 4 one year in ten, and holds off past December 21 one year in ten. A hard freeze of 28°F follows 12 days later, around December 9; in spring the one-in-ten date for 28°F is March 12, 12 days before the 32°F one. The freeze-free season lasts 270 days in a typical year, longer than at 71% of the 339 Texas stations; it reaches 306 days one year in ten and falls short of 238 one year in ten. On average 21 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 13 days longer, to about March 15, and return around November 12. Nights of 24°F, cold enough to damage hardier plants, come in 77% of winters and 16°F in 13%.
