Boston woke up Monday, May 25, 2026, to a gray, soggy scene, with fog hanging low and steady rain taking a swipe at the morning commute before conditions ease later in the day.
Morning Commute: Showers And Fog
Showers and patchy fog are expected through mid to late morning, with brief heavier downpours possible along the South Shore and in coastal neighborhoods. According to the National Weather Service, most spots should see the rain taper by mid to late afternoon and top out near 70°F, with new rainfall amounts generally between a tenth and a quarter of an inch. Visibility may drop in places, so drivers should stick to low beams, slow it down, and allow extra travel time.
Afternoon And The Week Ahead
The steady rain should pull back from west to east this afternoon, leaving mostly cloudy to partly sunny skies by evening and a better window for outdoor Memorial Day services later in the day. A warm surge is expected Tuesday, May 26, 2026, with mostly sunny skies and highs near 79°F, and Wednesday could push into the mid 80s with a slight chance of afternoon thunderstorms. Forecast timing for late week showers is still uncertain, so it is worth checking for updates if you have outdoor plans lined up.
Boaters And Harbor Plans
Small Craft Advisories were posted for some southern offshore zones through the early hours of Monday, so mariners should check local zone statements for ANZ areas before heading out. The National Weather Service highlights the highest rain totals along the South Coast, Cape and Islands and notes that localized downpours and brief thunderstorms are most likely there. If a harbor cruise or whale watch is on your schedule, confirm with your operator and consult the marine forecast for your route.
Quick Tips
Allow extra time for the morning commute, carry a rain layer, and use caution in areas of low visibility. For the latest timing and any event changes, check official organizer notices and the National Weather Service forecast before you head out.
