San Angelo, TX: when does the frost end?
The last spring frost here typically falls around 03/20, about 204 days from today. Fall's first freeze usually shows up around 11/10, roughly 232 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts San Angelo in Zone 8a (10 to 15°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 11 weeks until San Angelo's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/20 isn't a guarantee
03/20 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/12 and only about 1 year in 10 sees frost after that.
