Wrightstown, NJ 08641 Frost Dates
Wrightstown, NJ: when does the frost end?
Typically, the last spring freeze lands around 04/15, roughly 230 days out. Fall's first freeze usually shows up around 10/29, roughly 196 days after the last spring frost.
Wrightstown 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 9 weeks until Wrightstown's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/15 isn't a guarantee
04/15 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/29 and only about 1 year in 10 sees frost after that.
