Eagle Pass, TX 78853 Frost Dates

78853, near Eagle Pass, TX: the frost window

Zone 9a

Around 02/16 is the usual last spring frost, about 172 days away. Fall's first freeze usually shows up around 12/03, roughly 293 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Eagle Pass 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

Eagle Pass's growing season runs out in roughly 14 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 02/16 isn't a guarantee

02/16 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/19 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/10 and only about 1 year in 10 sees frost after that.

Eagle Pass against the rest of the dataset
