Bellefonte, PA: when does the frost end?

Zone 6b

The last spring frost here typically falls around 04/20, about 235 days from today. Fall's first freeze usually shows up around 10/26, roughly 187 days after the last spring frost.

Zone 6b (-5 to 0°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Bellefonte, not a forecast for this year.

Stretching the season past the first frost

With roughly 8 weeks until Bellefonte's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

How much risk comes with planting early here

04/20 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/07 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/06 and only about 1 year in 10 sees frost after that.
