Frost risk by date in Minneapolis

Half of springs at Minneapolis, KS see their last 32°F night by April 20; only one in ten is past it by April 6, and one in ten still has one after May 3. Planting tender crops after April 26 leaves a 30% risk of a frost on them, after April 30 20%, and after May 3 10%. The 13 days between the even-odds date and the one-in-ten date is narrower than at 65% of the 110 Kansas stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 19 in half of years, as early as October 3 one year in ten, and holds off past November 1 one year in ten. A hard freeze of 28°F follows 10 days later, around October 29; in spring the one-in-ten date for 28°F is April 24, 9 days before the 32°F one. The freeze-free season lasts 181 days in a typical year, shorter than at 69% of the 110 Kansas stations; it reaches 201 days one year in ten and falls short of 160 one year in ten. On average 120 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 9 days longer, to about April 29, and return around October 9. Severe cold of 16°F or below comes every winter, usually between November 27 and March 10.
