New Brighton, PA: when does the frost end?
Around 04/28 is the usual last spring frost, about 243 days away. Fall's first freeze usually shows up around 10/18, roughly 172 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts New Brighton 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 New Brighton's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/28 isn't a guarantee
04/28 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/15 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/15 and only about 1 year in 10 sees frost after that.
