Boston is waking up to generally dry, cool conditions Tuesday. The quiet start comes before a much rougher second half of the week.
Cool, Dry Weather Holds Through Thursday
Wednesday stays breezy with northeast winds and temperatures in the low 60s. Thursday looks similar, with cool and increasingly windy conditions, according to the National Weather Service.
Friday Brings Stronger Winds And Rain
A chance of showers arrives Friday, followed by a chance of showers during the day. Gale-force winds over marine areas could produce gusts up to 45 knots, while Friday night and Saturday bring likely showers.
The outlook is a notable escalation from Monday’s forecast, when the developing coastal low was still described as highly uncertain. Forecasters now say confidence is increasing that the system could bring strong winds, rough seas and coastal erosion late this week, although its exact track remains unsettled.
Rip Current Risk Continues Tuesday
A High Risk for Rip Currents remains in effect for portions of Massachusetts and Rhode Island from 6 a.m. through the evening of Tuesday, September 22, 2026. Anyone heading to the beach should swim near a lifeguard; if caught in a rip current, float, avoid swimming against it and signal for help.
For Boston, Tuesday through Thursday offer the cleaner windows for errands and outdoor plans. By Friday and into the weekend, residents should keep schedules flexible as wind, rain and coastal conditions become the main story.
