Nassau Bay, TX 77508 Frost Dates
Nassau Bay, TX: when does the frost end?
Around 01/31 is the usual last spring frost, about 156 days away. Fall's first freeze usually shows up around 12/14, roughly 317 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Nassau Bay 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
With roughly 15 weeks until Nassau Bay's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 01/31 isn't a guarantee
01/31 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 12/25 and only about 1 year in 10 sees frost after that.
