Fall River, MA 02724 Frost Dates
Fall River, MA: when does the frost end?
Around 04/11 is the usual last spring frost, about 226 days away. Fall's first freeze usually shows up around 11/02, roughly 203 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Fall River in Zone 7a (0 to 5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
With roughly 9 weeks until Fall River's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/11 isn't a guarantee
04/11 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/22 and only about 1 year in 10 sees frost after that.
