Victoria, TX 77903 Frost Dates
77903, near Victoria, TX: the frost window
Around 02/04 is the usual last spring frost, about 160 days away. Fall's first freeze usually shows up around 12/09, roughly 309 days after the last spring frost.
Zone 9b (25 to 30°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Victoria, not a forecast for this year.
Stretching the season past the first frost
Victoria's growing season runs out in roughly 15 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.
Why 02/04 isn't a guarantee
02/04 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/05 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/30 and only about 1 year in 10 sees frost after that.
