Frost risk by date in Bogata

Half of springs at Clarksville 2NE, TX see their last 32°F night by March 20; only one in ten is past it by February 28, and one in ten still has one after April 11. Planting tender crops after March 31 leaves a 30% risk of a frost on them, after April 4 20%, and after April 11 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 10 in half of years, as early as October 28 one year in ten, and holds off past November 29 one year in ten. A hard freeze of 28°F follows 13 days later, around November 23; in spring the one-in-ten date for 28°F is March 28, 14 days before the 32°F one. The freeze-free season lasts 233 days in a typical year, shorter than at 72% of the 339 Texas stations; it reaches 261 days one year in ten and falls short of 208 one year in ten. On average 57 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 16 days longer, to about April 5, and return around November 1. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 65%.
