Patchogue, NY 11772 Frost Dates
Patchogue, NY: when does the frost end?
Typically, the last spring freeze lands around 04/10, roughly 225 days out. Fall's first freeze usually shows up around 11/02, roughly 207 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Patchogue in Zone 7a (0 to 5°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 9 weeks until Patchogue's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/10 isn't a guarantee
04/10 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/31 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/25 and only about 1 year in 10 sees frost after that.
