Dawson, TX 76639 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.

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.
How much risk comes with planting early here
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.
