Navasota, TX: when does the frost end?

Zone 9a

Typically, the last spring freeze lands around 03/07, roughly 191 days out. Fall's first freeze usually shows up around 11/19, roughly 259 days after the last spring frost.

Zone 9a (20 to 25°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 Navasota, not a forecast for this year.

With roughly 12 weeks until Navasota's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

The actual range around Navasota's last frost

03/07 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/10 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/31 and only about 1 year in 10 sees frost after that.
