Stone Harbor, NJ 08246 Frost Dates

When can you plant in Stone Harbor, NJ?

Zone 7b

Typically, the last spring freeze lands around 04/01, roughly 216 days out. The first fall frost typically arrives around 11/09, about 222 frost-free days later.

Zone 7b (5 to 10°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Stone Harbor, not a forecast for this year.

What to do before the first frost

About 10 weeks of growing season left in Stone Harbor before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

How much risk comes with planting early here

04/01 is the middle of 30 years of NOAA records, not a promise. Plant by 03/19 and you're betting against frost in roughly 9 years out of 10. 04/15 is the safer bet, historically only a 1-in-10 chance of frost that late.
