Frost risk by date in Canadian

Half of springs at Miami, TX see their last 32°F night by April 16; only one in ten is past it by April 1, and one in ten still has one after May 1. Planting tender crops after April 22 leaves a 30% risk of a frost on them, after April 27 20%, and after May 1 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 94% of the 339 Texas stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 26 in half of years, as early as October 12 one year in ten, and holds off past November 7 one year in ten. A hard freeze of 28°F follows 8 days later, around November 3; in spring the one-in-ten date for 28°F is April 21, 10 days before the 32°F one. The freeze-free season lasts 192 days in a typical year, shorter than at 96% of the 339 Texas stations; it reaches 210 days one year in ten and falls short of 171 one year in ten. On average 116 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 April 28, and return around October 17. Severe cold of 16°F or below comes every winter, usually between December 1 and February 28.
