Houston, TX 77253 Frost Dates
When can you plant in Houston, TX?
Typically, the last spring freeze lands around 02/13, roughly 169 days out. The first fall frost typically arrives around 12/09, about 300 frost-free days later.
Zone 9b (25 to 30°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 Houston, not a forecast for this year.
What to do before the first frost
About 15 weeks of growing season left in Houston before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 02/13 isn't a guarantee
02/13 is the middle of 30 years of NOAA records, not a promise. Plant by 01/12 and you're betting against frost in roughly 9 years out of 10. 03/12 is the safer bet, historically only a 1-in-10 chance of frost that late.
