BOSTON (WHDH) - Across the Bay State, people are bracing for a third day of temperatures over 90 degrees.

A heat advisory has been issued for parts of Eastern and Western Massachusetts with the heat index expected to reach between 95 and 99 degrees.

Residents are urged to drink plenty of fluids, stay out of the sun, and stay in an air-conditioned room if possible.

Some school districts have planned to release students early or have canceled class all together due to the heat.

Boston recorded its first official heat wave of the year on Monday.

The city reached 90 degrees just after 11 a.m. with temperatures expected to rise into the mid-90s later in the day, according to 7NEWS Meteorologist Josh Wurster.

Mayor Kim Janey has declared a heat emergency for the city through Tuesday, allowing for multiple cooling centers to open.

A slight breeze flowed through M Street Beach Monday afternoon but did nothing to soothe the sweltering heat as dozens of people laid out and played in the water nearby.

“Especially after the year we’ve had, knowing that this heatwave is coming, I’ve just been like so excited,” one woman told 7NEWS. “To be here is amazing. I can’t wait to get in the water.”

An early June heatwave is unusual for the area. Some communities, like Worcester, are still waiting to see their first 90 degree day.

June 5 is the eigth earliest start to a heatwave recorded in this state with some of those records dating all the way back to the Dust Bowl.
