Rowlett, TX 75088 Frost Dates
Rowlett, TX: when does the frost end?
Around 03/07 is the usual last spring frost, about 191 days away. Fall's first freeze usually shows up around 11/21, roughly 259 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Rowlett in Zone 8b (15 to 20°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 12 weeks until Rowlett'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 02/18 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/29 and only about 1 year in 10 sees frost after that.
