Frost dates for Stockdale, PA, ZIP 15483

Zone 6b

Typically, the last spring freeze lands around 05/02, roughly 247 days out. The first fall frost typically arrives around 10/20, about 170 frost-free days later.

Stockdale 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

Zone 6b around Stockdale has about 8 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

Why 05/02 isn't a guarantee

05/02 is the middle of 30 years of NOAA records, not a promise. Plant by 04/17 and you're betting against frost in roughly 9 years out of 10. 05/20 is the safer bet, historically only a 1-in-10 chance of frost that late.
