Fall River, MA 02721 Frost Dates

When can you plant in Fall River, MA?

Zone 7a

Typically, the last spring freeze lands around 04/11, roughly 226 days out. The first fall frost typically arrives around 11/02, about 203 frost-free days later.

Fall River sits in USDA Zone 7a (0 to 5°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 9 weeks of growing season left in Fall River before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/11 isn't a guarantee

04/11 is the middle of 30 years of NOAA records, not a promise. Plant by 04/01 and you're betting against frost in roughly 9 years out of 10. 04/22 is the safer bet, historically only a 1-in-10 chance of frost that late.
