Laredo, TX 78045 Frost Dates
78045, near Laredo, TX: the frost window
Around 01/20 is the usual last spring frost, about 145 days away. Fall's first freeze usually shows up around 12/25, roughly 344 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Laredo in Zone 9b (25 to 30°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
Laredo's growing season runs out in roughly 17 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.
Why 01/20 isn't a guarantee
01/20 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/26 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/16 and only about 1 year in 10 sees frost after that.
