Frost dates for Bridgeport, PA, ZIP 19405
Typically, the last spring freeze lands around 04/08, roughly 223 days out. The first fall frost typically arrives around 10/31, about 203 frost-free days later.
The USDA Plant Hardiness Zone Map puts Bridgeport in Zone 7b (5 to 10°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost
Zone 7b around Bridgeport has about 9 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.
Why 04/08 isn't a guarantee
04/08 is the middle of 30 years of NOAA records, not a promise. Plant by 03/28 and you're betting against frost in roughly 9 years out of 10. 04/23 is the safer bet, historically only a 1-in-10 chance of frost that late.
