Fredonia, PA 16124 Frost Dates
Fredonia, PA: when does the frost end?
Around 05/15 is the usual last spring frost, about 260 days away. Fall's first freeze usually shows up around 10/03, roughly 140 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Fredonia 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 5 weeks until Fredonia's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/15 isn't a guarantee
05/15 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/30 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/01 and only about 1 year in 10 sees frost after that.
