Boston is starting Monday under light rain, with a damp, gray morning setting the tone for a cooler and noticeably humid day. Showers should remain possible through the afternoon, while temperatures top out near 75 degrees.

Rain showers are most likely before late morning, then should become more scattered, according to the National Weather Service. Most areas could see roughly a tenth to a quarter-inch of rain, with isolated heavier downpours possible, though widespread flooding is not expected.

Foggy And Damp Monday Night

Monday night stays mostly cloudy, with a chance of showers before 8 p.m. Patchy fog is expected to develop overnight as temperatures fall to around 68 degrees, so drivers could encounter reduced visibility during the late commute and early Tuesday morning.

Tuesday Offers A Brief Break

Tuesday should be mainly dry and a little brighter, though patchy morning fog and an isolated shower remain possible. Boston may reach about 78 degrees, with lighter northeast winds and a mix of sunshine and clouds.

Wednesday Brings The Week’s Warmest Weather

The best-looking day arrives Wednesday, when mostly sunny skies push temperatures to around 86 degrees. A chance of showers returns Thursday, but the day should still be mostly sunny with a high near 83, followed by a cooler and mostly sunny Friday near 76.

Showers Return For The Weekend

Periodic shower chances return Saturday and Sunday, with partly sunny to partly cloudy skies and highs in the mid-70s. Neither day is expected to be a total washout, but outdoor plans may need a flexible backup as Sunday carries the highest rain chance of the weekend.

Beachgoers Face Rip Current Danger

The National Weather Service has issued a high risk for rip currents along south-facing ocean beaches Monday, with a similar risk expected along east-facing beaches Tuesday. Anyone heading to the coast should check with lifeguards or beach staff and avoid entering rough surf alone.
