Quincy, MA 02136 Frost Dates

Quincy, MA: when does the frost end?

Zone 6b

Typically, the last spring freeze lands around 04/18, roughly 233 days out. Fall's first freeze usually shows up around 10/26, roughly 190 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Quincy in Zone 6b (-5 to 0°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 8 weeks until Quincy's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

The actual range around Quincy's last frost

04/18 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/07 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/30 and only about 1 year in 10 sees frost after that.
