Fort Lee, NJ 10452 Frost Dates

When can you plant in Fort Lee, NJ?

Zone 7b

The last spring frost here typically falls around 04/01, about 216 days from today. The first fall frost typically arrives around 11/16, about 230 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 Fort Lee, not a forecast for this year.

What to do before the first frost

About 11 weeks of growing season left in Fort Lee before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/01 isn't a guarantee

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. 04/12 is the safer bet, historically only a 1-in-10 chance of frost that late.
