Kenilworth, NJ 07061 Frost Dates
Kenilworth, NJ: when does the frost end?
Typically, the last spring freeze lands around 04/11, roughly 226 days out. Fall's first freeze usually shows up around 10/31, roughly 202 days after the last spring frost.
Zone 7a (0 to 5°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Kenilworth, not a forecast for this year.
Stretching the season past the first frost
With roughly 9 weeks until Kenilworth's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/11 isn't a guarantee
04/11 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/30 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/28 and only about 1 year in 10 sees frost after that.
