Frost Dates for 76570 — Rosebud, Texas

Half of springs at Cameron, TX see their last 32°F night by March 6; only one in ten is past it by February 7, and one in ten still has one after March 27. Planting tender crops after March 15 leaves a 30% risk of a frost on them, after March 20 20%, and after March 27 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.

In fall the first 32°F night comes by November 23 in half of years, as early as November 3 one year in ten, and holds off past December 20 one year in ten.
