77801, near Bryan, TX: the frost window

Zone 9a

The last spring frost here typically falls around 02/27, about 183 days from today. Fall's first freeze usually shows up around 11/30, roughly 278 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Bryan in Zone 9a (20 to 25°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Stretching the season past the first frost

Bryan's growing season runs out in roughly 13 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 02/27 isn't a guarantee

02/27 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/31 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/18 and only about 1 year in 10 sees frost after that.
