New Kensington, PA 15068 Frost Dates

When can you plant in New Kensington, PA?

Zone 6b

Typically, the last spring freeze lands around 04/16, roughly 231 days out. The first fall frost typically arrives around 11/02, about 199 frost-free days later.

New Kensington 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.

What to do before the first frost

About 9 weeks of growing season left in New Kensington before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/16 isn't a guarantee

04/16 is the middle of 30 years of NOAA records, not a promise. Plant by 03/31 and you're betting against frost in roughly 9 years out of 10. 05/02 is the safer bet, historically only a 1-in-10 chance of frost that late.
