Frost Dates for 77360 — Onalaska, Texas

Half of springs at Livingston 2 NNE, TX see their last 32°F night by March 1; only one in ten is past it by February 4, and one in ten still has one after March 27. Planting tender crops after March 12 leaves a 30% risk of a frost on them, after March 19 20%, and after March 27 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.
