Frost risk by date in Bauxite

Half of springs at Benton, AR see their last 32°F night by March 24; only one in ten is past it by March 3, and one in ten still has one after April 13. Planting tender crops after April 1 leaves a 30% risk of a frost on them, after April 6 20%, and after April 13 10%. The 20 days between the even-odds date and the one-in-ten date is wider than at 92% of the 105 Arkansas stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 7 in half of years, as early as October 26 one year in ten, and holds off past November 23 one year in ten. A hard freeze of 28°F follows 11 days later, around November 18; in spring the one-in-ten date for 28°F is March 29, 15 days before the 32°F one. The freeze-free season lasts 229 days in a typical year, longer than at 62% of the 105 Arkansas stations; it reaches 254 days one year in ten and falls short of 203 one year in ten. On average 64 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 14 days longer, to about April 7, and return around October 30. Nights of 24°F, cold enough to damage hardier plants, come in 100% of winters and 16°F in 76%.
