Coaldale, PA: when does the frost end?

Zone 6b

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.

Coaldale sits in USDA Zone 6b (-5 to 0°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

Stretching the season past the first frost

With roughly 8 weeks until Coaldale'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

04/23 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.
