Zone 9b

The last spring frost here typically falls around 01/31, about 156 days from today. The first fall frost typically arrives around 12/14, about 317 frost-free days later.

The USDA Plant Hardiness Zone Map puts Kemah in Zone 9b (25 to 30°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

Zone 9b around Kemah has about 15 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

Why 01/31 isn't a guarantee

01/31 is the middle of 30 years of NOAA records, not a promise. Plant by 03/05 and you're betting against frost in roughly 9 years out of 10. 12/25 is the safer bet, historically only a 1-in-10 chance of frost that late.
