Boston is having about as pleasant a Sunday as summer offers: sunny skies, a high near 82°F, light northeast wind at 3 to 9 mph, and zero percent chance of rain. If you’ve been putting off yard work, a run along the Charles River Esplanade, or an evening on the Boston Common, today’s the day, because the National Weather Service says much hotter, more humid air is barreling in by midweek.
Today’s Setup
High pressure settles in solidly today, keeping the air seasonably comfortable with dewpoints in the upper 50s to low 60s, pleasant, not sticky. Tonight stays mostly clear with a low around 65°F and a light south wind. Monday holds the pattern with sunny skies and a high near 90°F, though forecasters note haze may drift in from Canadian wildfires, filtering the sunshine through the first half of the week.
Best Window To Be Outside
Right now through Monday afternoon is the sweet spot. Low humidity, light breezes, and full sun make this the best stretch for anything outdoors, whether that’s Fenway Park events, a walk through the Public Garden, or yard work before the heat arrives. By Tuesday, the National Weather Service expects highs near 98°F with some spots flirting with triple digits, and heat-related statements are possible Tuesday and Wednesday as heat index values climb into the 90s to low 100s.
Heat And Haze Ahead
Once the ridge builds midweek, comfortable turns genuinely hot fast. Shift outdoor plans for Tuesday or Wednesday to early morning or evening. A pop-up canopy tent with weights is worth setting up for shade at any backyard gathering, and outdoor furniture covers will protect patio gear if the unsettled weather forecasters expect later this week, as an upper-level trough approaches, brings a stray storm. If you’d rather cool off in the water once the heat arrives, a 2-Person Intex Floating Lounge with Cooler is a nice pickup for the pool or a calm stretch of the Charles.
Gameday And Concert Weather
The Boston Red Sox host the Tampa Bay Rays at Fenway Park on July 17, right in the thick of the midweek heat, so plan for hot, muggy tailgating conditions, grab Official team gear on Fanatics, and Get tickets on SeatGeek. Music fans have options too: Meghan Trainor brings the Get In Girl Tour to TD Garden on July 17 (pick up a Meghan Trainor t-shirt), and Louis Tomlinson plays TD Garden July 14 in comfortable weather. Find tickets on StubHub for either show.
Dinner Idea
Tonight’s clear, calm evening is ideal for firing up a portable propane grill, burgers, steaks, or grilled chicken with corn on the cob all work well in these dry conditions. Keep an instant-read meat thermometer and grill brush and scraper set handy for easy cooking and cleanup. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Expect sunny and dry through Monday, then a jump to near 90s to upper 90s Tuesday and Wednesday with possible heat headlines. Later in the week, an upper-level trough may bring more unsettled, possibly stormy weather back to the region. For more, browse outdoor gear deals to get ready for the heat.
