Oak Hill, OH 45656 Frost Dates

When can you plant in Oak Hill, OH?

Zone 6b

Typically, the last spring freeze lands around 04/30, roughly 245 days out. The first fall frost typically arrives around 10/15, about 167 frost-free days later.

Oak Hill 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 7 weeks of growing season left in Oak Hill before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/30 isn't a guarantee

04/30 is the middle of 30 years of NOAA records, not a promise. Plant by 04/15 and you're betting against frost in roughly 9 years out of 10. 05/16 is the safer bet, historically only a 1-in-10 chance of frost that late.
