Boston records are kept at Logan International Airport, which is right by the ocean, so these temperatures tend to be milder than temperatures further inland. And if the sea breeze sets in in the right direction, it could keep temperatures at the airport from hitting record highs.
“We’re definitely a little ahead of schedule,” said Matthew Belk, meteorologist with the Boston Weather Services office. “The average first 90-degree day in Boston is June 8. It’s a bit earlier when you exit to Hartford, Connecticut; May 30 is usually the first average 90 degree day.

Skeen stressed the importance of taking the heat seriously.
“Make sure to hydrate, stay in the shade, protect yourself from the sun when possible,” Skeen said. “And keep an eye out for the people in your life who are more heat sensitive, like the young and old and those who might be compromised.”
The good news is that the heat wave will be short-lived. Once the cold front crosses the east coast on Monday, temperatures will drop back into the 60s and 70s for the northeast and mid-Atlantic.
