Horseheads, NY 14845 Frost Dates
Horseheads, NY: when does the frost end?
Around 05/09 is the usual last spring frost, about 254 days away. Fall's first freeze usually shows up around 10/09, roughly 151 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Horseheads in Zone 6a (-10 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 6 weeks until Horseheads's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
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 04/26 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/24 and only about 1 year in 10 sees frost after that.
