Boston is set for a mostly sunny Saturday with a high near 86°F, and while most neighborhoods stay dry, the National Weather Service has introduced a slight chance of showers and thunderstorms after 2 PM ET, mainly over the interior suburbs — so front-load your outdoor plans into the morning and early afternoon.
Today’s Setup
A warm airmass is holding over Southern New England thanks to a mid-level ridge, keeping highs in the mid-to-upper 80s through Sunday. That same ridge is starting to break down, which is why forecasters bumped in a slight chance of a stray shower or thunderstorm this afternoon. Winds stay light out of the south at 2 to 7 mph, and any storm that does fire could produce a quick, heavy downpour given moisture levels running over 1 inch of precipitable water.
Best Window To Be Outside
Morning through early afternoon is your golden window — think Charles River Esplanade jogs, a round at one of the local courses, or casting a line off the Harborwalk before clouds thicken later in the day. It’s a great call for a golf push cart if you’re squeezing in 18 holes before any pop-up storm, and anglers heading to the Charles or Boston Harbor should keep a fishing net foldable handy for a quick, dry-morning outing.
Rain, Wind, Or Storm Risk This Weekend
The bigger story is Sunday night into Monday: a deepening surface low tied to a digging upper-level trough tracks into New England, bringing a cold front with heavy rain and gusty winds that could linger into Tuesday. Sunday night’s rain chance jumps to 69%, and the NWS Boston/Norton office expects periodic rain chances to continue for much of next week. No severe weather outlook is in effect for Boston today, but keep an eye on the evening sky if you’re outdoors late.
Tonight’s Concerts And This Week’s Games
It’s a big night at Fenway Park with Phish taking the stage outdoors — worth watching that afternoon storm chance if you’re tailgating beforehand. Xfinity Center hosts Mötley Crüe tonight, MGM Music Hall at Fenway welcomes Fetty Wap, and TD Garden has The Red Clay Strays indoors, so grab a Red Clay Strays t-shirt before you head in. Zac Brown Band returns to Fenway Park Sunday under similarly warm, mostly dry skies. Looking ahead, the Boston Red Sox host the Chicago White Sox at Fenway Park on August 4, right as the cold front’s rain risk may still be lingering — gear up with a Boston Red Sox jersey or Boston Red Sox fitted cap and grab tickets on SeatGeek now. BTS brings the Arirang World Tour to Gillette Stadium on August 5, and J. Cole’s Fall-Off Tour hits TD Garden August 7 — a J. Cole hoodie makes a solid pickup either way.
What To Wear Or Bring
Light, breathable clothing and sun protection are the move for the sunny stretch — check out the UPF 50+ Sun Hoodie deal if you’re out on the water. Evenings stay muggy near 69°F, so a mosquito repellent spray is worth packing for backyard hangs.
Tonight’s Dinner
With dry, warm conditions lasting into the evening, it’s perfect grilling weather — burgers, steaks, or grilled chicken with corn on the cob all work. An instant-read meat thermometer and grill brush and scraper set make cleanup and doneness a breeze. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Sunday holds mostly dry with a high near 85°F before the cold front’s heavy rain and gusty winds arrive Sunday night into Monday, possibly lingering into Tuesday. For the latest updates, check the Boston outdoor gear guide before your next harbor outing.
