Harbor View, OH 43659 Frost Dates

When can you plant in Harbor View, OH?

Zone 6b

Typically, the last spring freeze lands around 04/20, roughly 235 days out. The first fall frost typically arrives around 10/27, about 188 frost-free days later.

The USDA Plant Hardiness Zone Map puts Harbor View in Zone 6b (-5 to 0°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 9 weeks of growing season left in Harbor View before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/20 isn't a guarantee

04/20 is the middle of 30 years of NOAA records, not a promise. Plant by 04/05 and you're betting against frost in roughly 9 years out of 10. 05/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
