Norwood, NY 13660 Frost Dates

13660, near Norwood, NY: the frost window

Zone 4b

Around 05/09 is the usual last spring frost, about 254 days away. Fall's first freeze usually shows up around 09/30, roughly 142 days after the last spring frost.

Norwood sits in USDA Zone 4b (-25 to -20°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

Norwood's growing season runs out in roughly 5 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 05/09 isn't a guarantee

05/09 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/27 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/25 and only about 1 year in 10 sees frost after that.
