Frost Dates for 77612 — Buna, Texas

Half of springs at Lumberton, TX see their last 32°F night by February 25; only one in ten is past it by January 29, and one in ten still has one after March 18. Planting tender crops after March 4 leaves a 30% risk of a frost on them, after March 10 20%, and after March 18 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 30 in half of years, as early as November 8 one year in ten, and holds off past December 21 one year in ten.

Nights of 24°F, cold enough to damage hardier plants, come in 64% of winters and 16°F in 5%.
