Naugatuck, CT 06403 Frost Dates

Naugatuck, CT: when does the frost end?

Zone 6b

The last spring frost here typically falls around 04/26, about 241 days from today. Fall's first freeze usually shows up around 10/16, roughly 175 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Naugatuck 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 7 weeks until Naugatuck's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 04/26 isn't a guarantee

04/26 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/11 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/09 and only about 1 year in 10 sees frost after that.
