Eagle Pass, TX 78877 Frost Dates
Eagle Pass, TX: when does the frost end?
Typically, the last spring freeze lands around 02/16, roughly 172 days out. 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
With roughly 14 weeks until Eagle Pass's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
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.
