Lynn, AR 72440 Frost Dates
Lynn, AR: when does the frost end?
Typically, the last spring freeze lands around 03/27, roughly 211 days out. Fall's first freeze usually shows up around 11/05, roughly 224 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Lynn in Zone 7b (5 to 10°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 10 weeks until Lynn'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
03/27 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/10 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.
