Frost risk by date in Mount Pleasant
Half of springs at Mt Pleasant, TX see their last 32°F night by March 24; only one in ten is past it by March 3, and one in ten still has one after April 13. Planting tender crops after April 1 leaves a 30% risk of a frost on them, after April 7 20%, and after April 13 10%. The 20 days between the even-odds date and the one-in-ten date is narrower than at 51% of the 339 Texas stations behind this site's ZIP pages.
In fall the first 32°F night comes by November 7 in half of years, as early as October 25 one year in ten, and holds off past November 29 one year in ten.
