A heat advisory remains in effect for much of eastern Massachusetts and the Connecticut River Valley, where temperatures could reach the upper 90s Monday afternoon, according to the National Weather Service.

The heat and humidity, which intensified this weekend, is expected to last through Tuesday before a new weather system arrives on Wednesday bringing cooler air and less humidity, forecasters said.

The heat advisory for portions of Massachusetts, Rhode Island and northern Connecticut will remain in effect until 8 p.m. Tuesday.

Forecasters said the advisory, “has been extended and expanded to include northeast CT, eastern MA, and central/northern RI for indices 95° to 99° Tuesday afternoon.”


“Take extra precautions if you work or spend time outside,” the advisory said. “When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible.”

By 2:54 p.m., the temperature in Boston had reached 95 degrees, and the temperature in Lawrence hit 93 degrees.

With temperatures expected to reach near the century mark, some school districts across the region decided to cancel after-school activities or send students home early.

The Boston Public Schools were “proceeding with instruction as normal,” but all after-school activities were cancelled Monday, according to BPS spokesman Xavier Andrews.

Boston’s city-operated pools have not yet opened for the season, but tot sprays will be open at parks and playgrounds throughout the city and cooling centers will operate from 10 a.m. to 6 p.m., officials said.

Acting Mayor Kim Janey announced that the heat emergency will remain in effect through Tuesday.

“It will be the first time this year that we’ve seen heat and humidity like this for an extended period of time,” Janey said in a statement. “We are opening our cooling centers so all residents have an option to come inside and cool off in air conditioning. I’m urging everyone to take precautions and find ways to stay cool over the next few days. Please watch out for each other. If you see someone out in the heat who appears in distress and needs help, call 911 immediately.”


Forecasters were also encouraging people to stay in air-conditioned spaces.

“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” forecasters wrote. “Young children and pets should never be left unattended in vehicles under any circumstances.”

In Braintree, the auditorium in Town Hall and the Braintree Department of Elder Affairs building would be open as cooling centers from 8:30 am to 4:30 pm., officials said.

Boston Common was largely empty Monday afternoon amid the first heat wave of 2021 — though a strong summer breeze helped keep temperatures down, as some passersby chose to relax in the shade.

Max Moffo, a 22-year-old tourist from Columbus, Ohio, stopped to eat lunch on a park bench on Boston Common Monday afternoon.

Moffo had plans to walk the freedom trail despite the heat.

“I packed lots of water,” he said.

He noted “the weather isn’t very picky.”

Moffo said he also had plans to go the beach later on Monday afternoon.

Chad and Michelle Dupuis, two 43-year-olds visiting Boston from Bellingham, said the heat derailed some of their plans for a day trip into the city. Initially planning to walk around Downtown Crossing before heading back to the common, the two instead decided to camp out in the shade and “people watch.”


“We did scale it back quite a bit,” Michelle Dupuis said.

“We made plans a couple days ago, [but] we didn’t expect it to be this hot,” said Chad Dupuis.

The shady areas of the common combined with the breeze made the duo determine it was “comfortable enough” to sit on the grass briefly.

“It’s definitely a bit better in the shade,” Michelle Dupuis said.

Sara Raposo, 33 and Evan Katz, 32, were relaxing on a bench after coming to Boston for a friend’s wedding.

They said they were “killing time” before their flight back to Denver.

Raposo said they “planned to find a place with air conditioning” before heading out.

“It’s a beautiful day. It’s just really hot,” added Katz.
