Frost Dates for 76554 — Little River Academy, Texas

Half of springs at Stillhouse Hollow Dam, TX see their last 32°F night by March 14; only one in ten is past it by February 22, and one in ten still has one after April 4. Planting tender crops after March 22 leaves a 30% risk of a frost on them, after March 29 20%, and after April 4 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.
