Hamburg, NJ 07462 Frost Dates
Hamburg, NJ: when does the frost end?
The last spring frost here typically falls around 05/01, about 246 days from today. Fall's first freeze usually shows up around 10/12, roughly 164 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Hamburg in Zone 6b (-5 to 0°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 6 weeks until Hamburg'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
05/01 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/19 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/18 and only about 1 year in 10 sees frost after that.
