Dawson, TX 76679 Frost Dates
Dawson, TX: when does the frost end?
The last spring frost here typically falls around 03/07, about 191 days from today. Fall's first freeze usually shows up around 11/23, roughly 261 days after the last spring frost.
Zone 8b (15 to 20°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 Dawson, not a forecast for this year.
Stretching the season past the first frost
With roughly 12 weeks until Dawson's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/07 isn't a guarantee
03/07 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/14 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/30 and only about 1 year in 10 sees frost after that.
