Boston, MA – Cool air and mostly clear skies will settle across Massachusetts tonight, with low temperatures dipping into the upper 40s inland and mid-50s along the coast. Drivers in lower-elevation valleys may encounter patchy fog by early Sunday morning, especially before sunrise.
According to the National Weather Service in Boston, the clear and calm setup tonight is followed by a stretch of near-perfect late-summer weather. Sunday will bring mostly sunny skies and highs between 72°F and 78°F. Expect slightly cooler temperatures along the coast, where local sea breezes will moderate the warmth.
Monday continues the trend with partly sunny skies and comfortable highs in the mid-70s. Light northeast winds will keep conditions pleasant for Labor Day activities across eastern and central Massachusetts.
No major hazards are expected, but motorists in fog-prone areas should use low beams and allow extra time for early morning travel. With low humidity and light winds, it’s a good time to plan outdoor plans before any unsettled weather returns midweek.
