Frost dates for Northampton, MA, ZIP 01096

Zone 6a

Around 05/13 is the usual last spring frost, about 258 days away. The first fall frost typically arrives around 10/02, about 144 frost-free days later.

The USDA Plant Hardiness Zone Map puts Northampton in Zone 6a (-10 to -5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

Zone 6a around Northampton has about 5 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

Why 05/13 isn't a guarantee

05/13 is the middle of 30 years of NOAA records, not a promise. Plant by 04/29 and you're betting against frost in roughly 9 years out of 10. 05/26 is the safer bet, historically only a 1-in-10 chance of frost that late.
