Newport, AR 72112 Frost Dates
Newport, 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 240 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Newport 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 Newport'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 02/28 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/04 and only about 1 year in 10 sees frost after that.
