Clinton, NJ 08867 Frost Dates

When can you plant in Clinton, NJ?

Zone 7a

Around 04/24 is the usual last spring frost, about 239 days away. The first fall frost typically arrives around 10/21, about 179 frost-free days later.

Zone 7a (0 to 5°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 Clinton, not a forecast for this year.

What to do before the first frost

About 8 weeks of growing season left in Clinton before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/24 isn't a guarantee

04/24 is the middle of 30 years of NOAA records, not a promise. Plant by 04/09 and you're betting against frost in roughly 9 years out of 10. 05/11 is the safer bet, historically only a 1-in-10 chance of frost that late.
