Boston woke up to a cool, soggy Sunday on May 24, 2026, with steady rain likely through the morning and patches of fog hanging around the harbor. Temperatures are stuck in the low 50s, and the high should be near 52°F this afternoon, with east winds gusting into the 20s. Wet streets and reduced visibility are slowing commutes and setting up a damp start for Memorial Day plans on Monday, May 25, 2026.
What To Expect Today
Rain showers are likely before 1 p.m. on Sunday, May 24, 2026, and then should continue through the afternoon with patchy fog and occasional heavier downpours. Expect a high near 52°F, east winds of 6 to 12 mph, and gusts up to 22 mph. New rainfall amounts of about a quarter to a half-inch are possible. Offshore waters will be rough, with seas building to 6 to 10 feet and Small Craft Advisories in effect, according to the National Weather Service.
Commute And Event Notes
Wet roads and limited visibility will slow both driving and walking commutes, so using low beams in the fog and building in extra travel time is a smart bet. MBTA riders should keep an eye on T-Alerts for any weather-related changes to commuter rail or ferry runs. Outdoor events on Monday, May 25, 2026, may start out damp in the morning but are expected to turn drier later in the day.
Looking Ahead
The steadier rain should pull offshore Monday night, and a notable warm-up follows, with highs near the upper 70s by Tuesday, May 26, 2026. We first flagged this holiday-weekend setup on May 21, but today's forecast tightens the timing and marine impacts for the harbor. If you have big outdoor plans for Memorial Day, plan for a damp morning and a drier afternoon.
