Bridgeport, CT 06825 Frost Dates
When can you plant in Bridgeport, CT?
Typically, the last spring freeze lands around 04/05, roughly 220 days out. The first fall frost typically arrives around 11/06, about 216 frost-free days later.
Bridgeport sits in USDA Zone 7a (0 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.
What to do before the first frost
About 10 weeks of growing season left in Bridgeport before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/05 isn't a guarantee
04/05 is the middle of 30 years of NOAA records, not a promise. Plant by 03/25 and you're betting against frost in roughly 9 years out of 10. 04/17 is the safer bet, historically only a 1-in-10 chance of frost that late.
