Boston is kicking off Tuesday with blue skies and a high near 88°F — but before you head to the Charles River Esplanade or Castle Island, know that west winds running 12 to 15 mph and very low humidity are combining to elevate fire danger conditions across the region today. For the full week ahead, bookmark the Boston weather forecast.
Today’s Setup
A high-pressure system sitting south of Long Island is keeping skies sunny and the air remarkably dry through tonight. The National Weather Service notes dewpoints will hold generally below 55°F, so despite the near-88°F high, the heat should feel comfortable rather than oppressive — a genuine gift for a June Tuesday. Expect a mostly clear overnight with a low around 63°F and southwest winds at 9 to 15 mph.
Best Window To Be Outside
The entire day looks clean. The Public Garden, the Harborwalk, and the Blue Hills Reservation are all prime destinations. If you want to cool off on the water later this week, this is the kind of forecast that makes a 2-person float with built-in cooler a very smart $24 investment right now.

Fire and Wind Risk
Today’s combination of west wind at 12 to 15 mph and bone-dry air is a real fire hazard. The National Weather Service is explicitly flagging dry conditions through tonight. If you’re grilling near the Fens or doing any yard cleanup out in the suburbs, keep a fire extinguisher home within reach and double-check that your smoke detector combo pack is working. Open flames in wooded areas — the Middlesex Fells, the Blue Hills — skip them entirely today.
If you’re setting up a pop-up canopy tent with weights for a backyard gathering, those afternoon gusts are a genuine test of your anchoring. Stake it down or bring it in before dark.
Tonight’s Events
Three shows hit the city tonight, all indoors — perfect for a breezy Tuesday: Les Misérables (Touring) at Citizens Opera House, the Forrest Frank: The Jesus Generation Tour at DCU Center in Worcester, and Amyl and the Sniffers at MGM Music Hall at Fenway. Tonight’s wind is a complete non-factor at any of these venues. Find tickets on StubHub if you’re still on the fence.
Next Few Days
Wednesday heats up again to near 89°F, but a front pushes through in the afternoon. Expect partly sunny skies through midday, then rain showers possible after 2 PM ET — 30% chance during the day, rising to 50% Wednesday night, per the National Weather Service. Thursday could push 91°F with more afternoon storm chances as humidity surges into the mid-to-upper 60s dewpoint range. Plan outdoor activities for mornings and keep an eye on radar.
Friday, June 12 is a big local sports and music night: the Dave Matthews Band plays Xfinity Center in Mansfield and the Boston Red Sox host the Texas Rangers at Fenway Park. Grab a Boston Red Sox jersey and Get tickets on SeatGeek before either show sells out.
Dinner tonight: Pasta primavera is a natural call on a warm, breezy evening — light, fast, and perfect for eating al fresco. You can order groceries on Amazon and have everything delivered well before dinner.
