Gallitzin, PA 16641 Frost Dates
Gallitzin, PA: when does the frost end?
Around 04/23 is the usual last spring frost, about 238 days away. Fall's first freeze usually shows up around 10/21, roughly 177 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Gallitzin in Zone 6a (-10 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 8 weeks until Gallitzin's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/23 isn't a guarantee
04/23 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/08 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/11 and only about 1 year in 10 sees frost after that.
