Frost risk by date in De Queen
Half of springs at Dequeen, AR see their last 32°F night by March 29; only one in ten is past it by March 7, and one in ten still has one after April 16. Planting tender crops after April 5 leaves a 30% risk of a frost on them, after April 10 20%, and after April 16 10%. The 18 days between the even-odds date and the one-in-ten date is wider than at 60% of the 105 Arkansas stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 5 in half of years, as early as October 22 one year in ten, and holds off past November 22 one year in ten. A hard freeze of 28°F follows 12 days later, around November 17; in spring the one-in-ten date for 28°F is April 3, 13 days before the 32°F one. The freeze-free season lasts 222 days in a typical year, shorter than at 53% of the 105 Arkansas stations; it reaches 249 days one year in ten and falls short of 199 one year in ten.
