Boston is baking under sunny skies today, August 7, with the temperature climbing to a high near 91°F and heat index values as high as 98 — hot enough that the National Weather Service has kept a Heat Advisory in effect through at least this evening. If you’ve got outdoor plans, front-load them into the morning and save anything strenuous for after sunset.
Today’s Setup
West wind stays light at around 6 mph, so there’s no breeze to cut the mugginess. Per the NWS Boston/Norton forecast office, dewpoints are climbing back into the low 70s today, which is what’s driving those triple-digit-feeling heat index numbers. Overnight lows only dip to around 73°F with little relief, and there’s a slight chance of showers and thunderstorms after 4 AM as the tropical airmass stays parked over the region.
Best Window To Be Outside
Early morning, before roughly 10 AM, is your best bet for a run along the Charles River Esplanade or a walk through the Boston Common before the heat index climbs toward 98. If you’re headed to Revere Beach or Carson Beach to cool off, midday through late afternoon works too — just expect full sun with no real cloud cover until evening.
Storm & Heat Risk
The Weather Prediction Center has Boston in a Marginal Risk zone for excessive rainfall today into Saturday, as deep tropical moisture sits over the Eastern Seaboard and any storms are driven by local mesoscale features rather than one big organized system. Saturday brings a 30% chance of showers and thunderstorms after 7 AM, continuing into Saturday night at 35%. The bigger story through the weekend is the heat itself: Saturday and Sunday run only 2-4 degrees cooler, so “feels like” temperatures stay in the low 90s even as highs ease toward 89°F.
What To Wear Or Bring
Light, breathable layers are the move — grab men’s sport sandals or a women’s swimsuit if the beach is calling. Headed out fishing or on the water this weekend? Don’t miss Score a UPF 50+ Sun Hoodie for Just $5 This Fishing Season. Keep water on hand in an insulated tumbler 30oz, and don’t skip sunscreen even under hazy skies.
Gameday & Weekend Events
The Boston Red Sox host the Athletics at Fenway Park tonight — expect it to still feel like the high 80s at first pitch, so hydrate before you go and pick up Official team gear on Fanatics if you need Sox colors. Over at Citizens House of Blues Boston, Qveen Herby plays her Isle of Qveen Tour tonight, and J. Cole’s Fall-Off Tour lands at TD Garden — check our J. Cole concert weather rundown before you head out, then Get tickets on SeatGeek or Find tickets on StubHub. Saturday, the New England Revolution take on Houston Dynamo at Gillette Stadium, with similarly hot, humid conditions expected for tailgating.
Tonight’s Dinner Idea
With heat like this, skip the stove. A cold Thai noodle salad or a build-your-own wrap bar keeps the kitchen cool, and a smoothie bowl made in a high-powered blender is an easy way to beat the heat. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Shower and storm chances should fade Sunday as slightly drier air moves in, though humidity lingers into the weekend. The NWS notes unsettled weather and continuing high humidity may return early next week, so keep an eye on the forecast if you’re planning outdoor time beyond the weekend.
