78551, near Combes, TX: the frost window

Zone 10a

Around 01/08 is the usual last spring frost, about 133 days away. Fall's first freeze usually shows up around 12/29, roughly 357 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Combes in Zone 10a (30 to 35°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

Combes's growing season runs out in roughly 18 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 01/08 isn't a guarantee

01/08 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/17 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/12 and only about 1 year in 10 sees frost after that.

Combes against the rest of the dataset
