Boston is enjoying a sunny, comfortable Tuesday with a high near 84°F, a light west wind around 7 mph, and virtually no rain chance — the kind of day to get outside before summer’s heavier humidity moves back in. Head to the Charles River Esplanade for a run, tee off at a local course, or grab a seat at Fenway Park tonight, because this is about as pleasant as August gets in Boston.

Today’s Setup

The National Weather Service Boston/Norton office says a weak area of high pressure is building in behind yesterday’s cold front, clearing the sky and keeping things dry with a high near 84°F today and a comfortable low around 64°F tonight under partly cloudy skies. Winds stay light, shifting from west to southwest by evening. Enjoy it — forecasters note dew points surge into the mid-70s starting Wednesday as a Bermuda high pulls warm, humid air up from the Atlantic, bringing near-oppressive humidity through the weekend.

Best Window To Be Outside

With 0% rain chance and low humidity, today is wide open for outdoor plans from morning through sunset. Wednesday looks nearly as good — mostly sunny, high near 84°F — before humidity and afternoon thunderstorm chances build in Thursday (88°F, a slight chance of showers after 5 PM ET) and continue into the weekend as PWATs climb toward 2 inches, raising the risk of heavy, fast-moving downpours on any given afternoon.

Red Sox Homestand & Weekend Shows

The Boston Red Sox host the Chicago White Sox at Fenway Park today, Wednesday, and Thursday, with the Athletics arriving Friday, August 7 — all outdoors, and tonight’s game should have ideal tailgating weather with sunny skies and low humidity. Get tickets on SeatGeek or Find tickets on StubHub, and gear up with a Boston Red Sox jersey or Boston Red Sox fitted cap. Music fans have options too: BTS brings the ARIRANG World Tour to Gillette Stadium on Wednesday, August 5, with dry, warm conditions expected, and J. Cole’s Fall-Off Tour stops at TD Garden on August 7.

What To Wear Or Bring

Light, breathable clothing works fine today, but sun protection matters under mostly clear skies — a UV protection sun hat helps at the ballpark or on the course, and right now you can grab a UPF 50+ sun hoodie for $5, a steal for anyone spending the day outside. Golfers should toss a golf divot repair tool in the bag while the courses are dry and firm. Once humidity builds Wednesday, start watching the sky for pop-up storms Thursday onward.

Dry, mild evening air makes tonight ideal for firing up the grill — think burgers, steaks, or grilled chicken with corn on the cob. An instant-read meat thermometer takes the guesswork out of doneness, and a grill brush and scraper set keeps the grates ready to go. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Enjoy today and Wednesday’s dry stretch — after that, the National Weather Service says heat and humidity build in hard, with highs of 85-90°F and dew points in the low-to-mid 70s Thursday through the weekend, plus a daily chance of diurnal thunderstorms capable of dropping heavy rain given PWATs near 2 inches. Heat headlines are being considered for the second half of the week, so plan outdoor activities for mornings once we get past Wednesday.

Upcoming Home Games

Plan around the forecast — grab tickets, gear up, and see kickoff conditions.
