Rockport, TX: when does the frost end?

Zone 9b

Typically, the last spring freeze lands around 01/31, roughly 156 days out. Fall's first freeze usually shows up around 12/25, 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 Rockport, not a forecast for this year.

Stretching the season past the first frost

With roughly 17 weeks until Rockport's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

How much risk comes with planting early here

01/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/28 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/26 and only about 1 year in 10 sees frost after that.
