Bridgeport, CT 06824 Frost Dates
Bridgeport, CT: when does the frost end?
Typically, the last spring freeze lands around 04/05, roughly 220 days out. Fall's first freeze usually shows up around 11/06, roughly 216 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Bridgeport in Zone 7a (0 to 5°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 10 weeks until Bridgeport's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/05 isn't a guarantee
04/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/25 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/17 and only about 1 year in 10 sees frost after that.
