Frost risk by date in Yoakum
Half of springs at Yoakum, TX 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 23. Planting tender crops after March 10 leaves a 30% risk of a frost on them, after March 15 20%, and after March 23 10%. The 21 days between the even-odds date and the one-in-ten date is wider than at 50% 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 30 in half of years, as early as November 7 one year in ten, and holds off past December 26 one year in ten. A hard freeze of 28°F follows 17 days later, around December 17; in spring the one-in-ten date for 28°F is March 12, 11 days before the 32°F one. The freeze-free season lasts 276 days in a typical year, longer than at 76% of the 339 Texas stations; it reaches 310 days one year in ten and falls short of 243 one year in ten. On average 17 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 12 days longer, to about March 14, and return around November 16. Nights of 24°F, cold enough to damage hardier plants, come in 66% of winters and 16°F in 2%.
