Newfane, VT 05356 Frost Dates
Newfane, VT: when does the frost end?
Around 05/14 is the usual last spring frost, about 259 days away. Fall's first freeze usually shows up around 10/04, roughly 143 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Newfane in Zone 5a (-20 to -15°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 5 weeks until Newfane's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/14 isn't a guarantee
05/14 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/30 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/26 and only about 1 year in 10 sees frost after that.
