Santa Anna, TX 76845 Frost Dates

When can you plant in Santa Anna, TX?

Zone 8b

Typically, the last spring freeze lands around 03/18, roughly 202 days out. The first fall frost typically arrives around 11/12, about 239 frost-free days later.

Zone 8b (15 to 20°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Santa Anna, not a forecast for this year.

What to do before the first frost

About 11 weeks of growing season left in Santa Anna before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 03/18 isn't a guarantee

03/18 is the middle of 30 years of NOAA records, not a promise. Plant by 02/28 and you're betting against frost in roughly 9 years out of 10. 04/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
