Frost risk by date in Crescent

Half of springs at Marshall 3SSE Mesonet, OK see their last 32°F night by April 11; only one in ten is past it by March 24, and one in ten still has one after April 29. Planting tender crops after April 18 leaves a 30% risk of a frost on them, after April 24 20%, and after April 29 10%. The 18 days between the even-odds date and the one-in-ten date is wider than at 60% of the 114 Oklahoma stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 31 in half of years, as early as October 16 one year in ten, and holds off past November 13 one year in ten. A hard freeze of 28°F follows 7 days later, around November 7; in spring the one-in-ten date for 28°F is April 15, 14 days before the 32°F one. The freeze-free season lasts 201 days in a typical year, shorter than at 83% of the 114 Oklahoma stations; it reaches 225 days one year in ten and falls short of 179 one year in ten. On average 95 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 23, and return around October 22. Severe cold of 16°F or below comes every winter, usually between December 9 and February 23.
