Boston is starting Memorial Day with rain showers and patchy fog, and if you had outdoor plans for this morning, consider this your cue to linger over coffee. The National Weather Service puts the precipitation chance at 90%, but the wet weather is expected to taper from west to east through the mid-to-late afternoon — around 2–3 PM ET for most of the metro.
Today’s Setup
A warm front pushing north has loaded the atmosphere with moisture, and the NWS is flagging brief heavy downpours and a possible thunderstorm this morning, especially along the South Shore. The bright side: the high reaches a mild 71°F — about 15 degrees warmer than yesterday — and winds turn westerly this afternoon as drier air filters in behind the frontal passage. Tonight looks pleasant with partly cloudy skies and a low around 57°F. The NWS even hints at a scenic sunset over the harbor as skies clear from west to east this evening.
Best Window To Be Outside
Hold off until after 2 PM ET. Once the front clears, the Esplanade, Castle Island, and the South Boston waterfront should all see improving conditions. Late afternoon is your best bet for a holiday walk or a backyard gathering — just don’t bother firing up the grill until then.
Rain Risk
The 90% precipitation chance is real, with brief heavy downpours possible through midday. No flood alerts are in place for the Boston metro, but expect puddles and ponding in low spots around Allston, the Fenway neighborhood, and anywhere drainage tends to back up. Keep an umbrella or rain jacket handy until mid-afternoon.
Red Sox & Upcoming Events
The weather rebounds just in time for baseball. The Boston Red Sox host the Atlanta Braves at Fenway Park on Tuesday, May 26 under mostly sunny skies and a high near 81°F — about as good as ballgame weather gets. Grab a Boston Red Sox jersey or a Boston Red Sox fitted cap and enjoy every inning. The series runs through Thursday (May 28), with Wednesday bringing a slight 27% shower chance and temps near 86°F. Find tickets on StubHub or Get tickets on SeatGeek. Tuesday’s sunshine also makes it a prime day for golf — check out the Callaway Big Bertha Fairway Wood deal if you’re looking to upgrade your bag for the season.
Wednesday night, the Electric Callboy: TANZNEID WORLD TOUR hits MGM Music Hall at Fenway — fully indoors, so no weather worries there. And Don Toliver brings the Octane Tour to TD Garden on May 30; a Don Toliver hoodie makes perfect sense for a late-spring Boston evening that can still turn chilly.
Rainy Day Meal Idea
A soggy Memorial Day calls for slow cooker chili or a hearty beef stew. Load up a programmable slow cooker this morning and dinner practically makes itself by the time skies clear this afternoon. An enameled cast iron Dutch oven is equally perfect for a big pot of New England clam chowder. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Tuesday is the clear standout — sunny and 81°F, no excuses to stay inside. Wednesday warms to near 86°F with that slight shower chance. The NWS expects above-normal temperatures through mid-week before easing back toward seasonal norms late next week, with a couple of rain chances but no washouts expected. Stay current with the Boston weather forecast as the week develops.
