Half of springs at Poinsett Sp, AR see their last 32°F night by March 28; only one in ten is past it by March 8, and one in ten still has one after April 11. Planting tender crops after April 3 leaves a 30% risk of a frost on them, after April 6 20%, and after April 11 10%. The 14 days between the even-odds date and the one-in-ten date is the narrowest 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 12 days later, around November 19; in spring the one-in-ten date for 28°F is April 2, 9 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 248 days one year in ten and falls short of 202 one year in ten.
