Princeton, WV 24732 Frost Dates
Princeton, WV: when does the frost end?
Around 04/21 is the usual last spring frost, about 236 days away. Fall's first freeze usually shows up around 10/22, roughly 182 days after the last spring frost.
Princeton sits in USDA Zone 7a (0 to 5°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 8 weeks until Princeton's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/21 isn't a guarantee
04/21 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/06 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/11 and only about 1 year in 10 sees frost after that.
