Frost risk by date in Hazen
Half of springs at Des Arc, AR see their last 32°F night by March 11; only one in ten is past it by February 23, and one in ten still has one after April 1. Planting tender crops after March 20 leaves a 30% risk of a frost on them, after March 26 20%, and after April 1 10%. The 21 days between the even-odds date and the one-in-ten date is wider than at 97% of the 105 Arkansas 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 14 in half of years, as early as October 31 one year in ten, and holds off past December 2 one year in ten. A hard freeze of 28°F follows 12 days later, around November 26; in spring the one-in-ten date for 28°F is March 19, 13 days before the 32°F one. The freeze-free season lasts 247 days in a typical year, longer than at 97% of the 105 Arkansas stations; it reaches 271 days one year in ten and falls short of 221 one year in ten. On average 50 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 March 27, and return around November 3. Nights of 24°F, cold enough to damage hardier plants, come in 99% of winters and 16°F in 63%.
