Frost risk by date in Hindsville

Half of springs at Huntsville 1 SSW, AR see their last 32°F night by March 30; only one in ten is past it by March 11, and one in ten still has one after April 15. Planting tender crops after April 5 leaves a 30% risk of a frost on them, after April 8 20%, and after April 15 10%. The 16 days between the even-odds date and the one-in-ten date is narrower than at 65% 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 24 one year in ten, and holds off past November 23 one year in ten. A hard freeze of 28°F follows 10 days later, around November 17; in spring the one-in-ten date for 28°F is April 4, 11 days before the 32°F one. The freeze-free season lasts 224 days in a typical year, shorter than at 47% of the 105 Arkansas stations; it reaches 247 days one year in ten and falls short of 201 one year in ten. On average 67 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 11 days longer, to about April 10, and return around October 28. Severe cold of 16°F or below comes in 99% of winters, usually between December 22 and February 16.
