This Is When Fall Will Arrive In Massachusetts: Forecasters Say

MASSACHUSETTS — If you're ready for the crisp, cool weather that autumn brings, Bay Staters might be waiting a bit longer this year, according to a newly released fall forecast from AccuWeather.

Summer warmth and humidity are expected to persist across the eastern United States through the start of autumn, delaying the arrival of true fall-like weather conditions, AccuWeather said in a forecast released on Wednesday.

Temperatures in Massachusetts are expected to be about 2-3 degrees higher than the historical average during September, October and November.

"A slower transition to fall is expected along much of the East Coast from the Carolinas to parts of the Northeast and even New England," AccuWeather lead long-range expert Paul Pastelok said. "There is a clear trend of hot and sticky summer weather sticking around longer into the back-to-school season across much of the East Coast and many other parts of the country."

Meteorological fall starts on Monday, Sept. 1, while astronomical autumn starts on the equinox at 2:19 p.m. EDT on Monday, Sept. 22.

According to AccuWeather, chilly transitions will have people reaching for hoodies and heavier coats in late October and into November as intrusions of cold air become more frequent.

The cold air will likely arrive first and be most pronounced in Midwest states, including North Dakota, South Dakota, Minnesota, Iowa, Wisconsin, Illinois and Michigan.

The remaining months of the 2025 hurricane season could see tropical storms interact with slow-moving fronts, which could trigger heavy rainfall and flash flooding at times from the central Gulf Coast to the Appalachians.

The threat of tropical storms remains high for the Atlantic and Gulf coasts, AccuWeather forecasters said.

AccuWeather has predicted an active Atlantic hurricane season, with 13-18 named storms, including seven to 10 hurricanes, three to five major hurricanes, and three to six direct impacts to the United States.

Tropical storms will be fueled by abnormally warm waters, which could cause hurricanes to potentially rapidly intensify near coastal cities from late summer into autumn.

"Development can be quick, as they tend to form near land over the Southwest Atlantic, Gulf and Caribbean, giving short time to prepare, rather than farther out over the Atlantic," AccuWeather lead hurricane expert Alex DaSilva said.

The 2025 hurricane season began on June 1 and will end on Nov. 30.

Accuweather's forecast said snow may arrive early in the Rockies, downwind of the Great Lakes and the coldest spots of the Plains, typical spots for early-season wintry weather.

The first snowfall of the season will likely come to higher elevations of central and western Massachusetts in late November or early December, with snow arriving later in Greater Boston.
