Frost Dates for 76511 — Bartlett, Texas

Half of springs at Granger Dam, TX see their last 32°F night by March 5; only one in ten is past it by February 13, and one in ten still has one after March 31. Planting tender crops after March 14 leaves a 30% risk of a frost on them, after March 20 20%, and after March 31 10%. The 26 days between the even-odds date and the one-in-ten date is wider than at 84% of the 339 Texas stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
