Frost risk by date in Cameron
Half of springs at Cameron, MO see their last 32°F night by April 15; only one in ten is past it by April 3, and one in ten still has one after April 29. Planting tender crops after April 21 leaves a 30% risk of a frost on them, after April 24 20%, and after April 29 10%. The 14 days between the even-odds date and the one-in-ten date is narrower than at 80% of the 158 Missouri stations behind this site's ZIP pages.
In fall the first 32°F night comes by October 24 in half of years, as early as October 10 one year in ten, and holds off past November 6 one year in ten.
