Frost Dates for 75790 — Van, Texas

Half of springs at Mineola, TX see their last 32°F night by March 20; only one in ten is past it by February 28, and one in ten still has one after April 10. Planting tender crops after March 29 leaves a 30% risk of a frost on them, after April 3 20%, and after April 10 10%. The 21 days between the even-odds date and the one-in-ten date is wider than at 50% of the 339 Texas stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
