Torrington, CT: when does the frost end?

Zone 6a

Around 05/08 is the usual last spring frost, about 253 days away. Fall's first freeze usually shows up around 10/05, roughly 151 days after the last spring frost.

Torrington sits in USDA Zone 6a (-10 to -5°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 5 weeks until Torrington'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

05/08 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/24 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/22 and only about 1 year in 10 sees frost after that.
