Sherman, TX 75092 Frost Dates
Sherman, TX: when does the frost end?
Around 03/14 is the usual last spring frost, about 198 days away. Fall's first freeze usually shows up around 11/19, roughly 250 days after the last spring frost.
Zone 8a (10 to 15°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 Sherman, not a forecast for this year.
Stretching the season past the first frost
With roughly 12 weeks until Sherman's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/14 isn't a guarantee
03/14 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/25 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/01 and only about 1 year in 10 sees frost after that.
