Danielson, CT 02814 Frost Dates

Danielson, CT: when does the frost end?

Zone 6b

Around 05/01 is the usual last spring frost, about 246 days away. Fall's first freeze usually shows up around 10/09, roughly 161 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Danielson in Zone 6b (-5 to 0°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 Danielson's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

How much risk comes with planting early here

05/01 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/20 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/17 and only about 1 year in 10 sees frost after that.
