Huntsville, TX 77349 Frost Dates
When can you plant in Huntsville, TX?
Typically, the last spring freeze lands around 03/02, roughly 186 days out. The first fall frost typically arrives around 11/26, about 272 frost-free days later.
The USDA Plant Hardiness Zone Map puts Huntsville in Zone 9a (20 to 25°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost
About 13 weeks of growing season left in Huntsville 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 01/31 and you're betting against frost in roughly 9 years out of 10. 03/24 is the safer bet, historically only a 1-in-10 chance of frost that late.
