Clarendon, AR 72029 Frost Dates
Clarendon, AR: when does the frost end?
Around 03/18 is the usual last spring frost, about 202 days away. Fall's first freeze usually shows up around 11/11, roughly 237 days after the last spring frost.
Clarendon sits in USDA Zone 8a (10 to 15°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.
Stretching the season past the first frost
With roughly 11 weeks until Clarendon's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/18 isn't a guarantee
03/18 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/06 and only about 1 year in 10 sees frost after that.
