Clarksville, AR 72830 Frost Dates
Clarksville, AR: when does the frost end?
Typically, the last spring freeze lands around 03/24, roughly 208 days out. Fall's first freeze usually shows up around 11/10, roughly 233 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Clarksville 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 Clarksville's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/24 isn't a guarantee
03/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/04 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/10 and only about 1 year in 10 sees frost after that.
