Clifton, TN 38425 Frost Dates
Clifton, TN: when does the frost end?
Around 04/14 is the usual last spring frost, about 229 days away. Fall's first freeze usually shows up around 10/24, roughly 192 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Clifton 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 8 weeks until Clifton's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/14 isn't a guarantee
04/14 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/28 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/30 and only about 1 year in 10 sees frost after that.
