Lubbock, TX 79430 Frost Dates
79430, near Lubbock, TX: the frost window
Around 04/04 is the usual last spring frost, about 219 days away. Fall's first freeze usually shows up around 11/02, roughly 210 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Lubbock in Zone 7b (5 to 10°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
Lubbock's growing season runs out in roughly 9 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.
Why 04/04 isn't a guarantee
04/04 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/17 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/22 and only about 1 year in 10 sees frost after that.
