Friendswood, 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 12/27, roughly 328 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 Friendswood, not a forecast for this year.
Stretching the season past the first frost
With roughly 17 weeks until Friendswood'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 01/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/05 and only about 1 year in 10 sees frost after that.
