Frost Dates for 76180 — North Richland Hills, Texas

Half of springs at Fort Worth Wsfo, TX see their last 32°F night by March 10; only one in ten is past it by February 21, and one in ten still has one after March 31. Planting tender crops after March 18 leaves a 30% risk of a frost on them, after March 23 20%, and after March 31 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.
