Frost risk by date in Albany

Half of springs at Albany, MO see their last 32°F night by April 17; only one in ten is past it by April 5, and one in ten still has one after April 30. Planting tender crops after April 22 leaves a 30% risk of a frost on them, after April 25 20%, and after April 30 10%. The 13 days between the even-odds date and the one-in-ten date is narrower than at 94% of the 158 Missouri stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 21 in half of years, as early as October 6 one year in ten, and holds off past October 31 one year in ten. A hard freeze of 28°F follows 8 days later, around October 29; in spring the one-in-ten date for 28°F is April 22, 8 days before the 32°F one. The freeze-free season lasts 185 days in a typical year, shorter than at 79% of the 158 Missouri stations; it reaches 202 days one year in ten and falls short of 165 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 April 27, and return around October 10. Severe cold of 16°F or below comes every winter, usually between November 24 and March 10.
