Frost risk by date in Kentland

Half of springs at Kentland, IN see their last 32°F night by April 23; only one in ten is past it by April 10, and one in ten still has one after May 8. Planting tender crops after April 30 leaves a 30% risk of a frost on them, after May 3 20%, and after May 8 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 70% of the 125 Indiana stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 14 in half of years, as early as October 1 one year in ten, and holds off past October 29 one year in ten. A hard freeze of 28°F follows 11 days later, around October 25; in spring the one-in-ten date for 28°F is April 26, 12 days before the 32°F one. The freeze-free season lasts 175 days in a typical year, shorter than at 69% of the 125 Indiana stations; it reaches 194 days one year in ten and falls short of 153 one year in ten. On average 133 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 10 days longer, to about May 3, and return around October 5. Severe cold of 16°F or below comes every winter, usually between November 25 and March 14.
