Socorro, TX 79940 Frost Dates

When can you plant in Socorro, TX?

Zone 8b

The last spring frost here typically falls around 03/02, about 186 days from today. The first fall frost typically arrives around 11/20, about 261 frost-free days later.

Socorro sits in USDA Zone 8b (15 to 20°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

What to do before the first frost

About 12 weeks of growing season left in Socorro before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 03/02 isn't a guarantee

03/02 is the middle of 30 years of NOAA records, not a promise. Plant by 02/12 and you're betting against frost in roughly 9 years out of 10. 03/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
