Woodstock, VT 05009 Frost Dates

05009, near Woodstock, VT: the frost window

Zone 5a

Around 05/13 is the usual last spring frost, about 258 days away. Fall's first freeze usually shows up around 10/01, roughly 141 days after the last spring frost.

How much risk comes with planting early here

05/13 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/29 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/27 and only about 1 year in 10 sees frost after that.
