Shippenville, PA 16058 Frost Dates

When can you plant in Shippenville, PA?

Zone 6a

Around 05/10 is the usual last spring frost, about 255 days away. The first fall frost typically arrives around 10/12, about 155 frost-free days later.

The USDA Plant Hardiness Zone Map puts Shippenville in Zone 6a (-10 to -5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

About 6 weeks of growing season left in Shippenville before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/10 isn't a guarantee

05/10 is the middle of 30 years of NOAA records, not a promise. Plant by 04/24 and you're betting against frost in roughly 9 years out of 10. 05/28 is the safer bet, historically only a 1-in-10 chance of frost that late.
