Amsterdam, NY 12010 Frost Dates
Amsterdam, NY: when does the frost end?
The last spring frost here typically falls around 05/07, about 252 days from today. Fall's first freeze usually shows up around 10/07, roughly 153 days after the last spring frost.
Amsterdam sits in USDA Zone 5b (-15 to -10°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 6 weeks until Amsterdam's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/07 isn't a guarantee
05/07 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/22 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/23 and only about 1 year in 10 sees frost after that.
