Half of springs at Lindsay 2 W, OK see their last 32°F night by April 13; only one in ten is past it by March 29, and one in ten still has one after April 28. Planting tender crops after April 19 leaves a 30% risk of a frost on them, after April 23 20%, and after April 28 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 86% of the 114 Oklahoma stations behind this site's ZIP pages.
In fall the first 32°F night comes by October 27 in half of years, as early as October 12 one year in ten, and holds off past November 10 one year in ten. A hard freeze of 28°F follows 8 days later, around November 4; in spring the one-in-ten date for 28°F is April 19, 9 days before the 32°F one. The freeze-free season lasts 196 days in a typical year, shorter than at 91% of the 114 Oklahoma stations; it reaches 218 days one year in ten and falls short of 174 one year in ten.
