Boston, Mass. – Sweltering temperatures and thick humidity are blanketing Massachusetts and much of Southern New England this week, prompting a Heat Advisory for millions through 7 p.m. Thursday. Residents from Boston to Hartford could see heat index values approach or exceed 100°F, especially on Wednesday as conditions peak.
According to the National Weather Service in Boston, the advisory covers most of Southern New England, excluding the Berkshires, southern Connecticut, and Cape Cod/Islands. The region faces “moderate to high” heat risk, with the worst conditions likely in densely populated cities including Boston, Worcester, Springfield, Providence, and Hartford.
Prolonged exposure to high heat and humidity may lead to heat-related illnesses, especially for vulnerable populations such as children, seniors, and those without access to air conditioning. Health officials urge everyone to stay hydrated, limit outdoor activities during the afternoon, wear light-colored clothing, and check on neighbors.
In Boston, city officials are extending cooling center hours, while Worcester Public Schools have postponed all outdoor activities. Major roadways such as I-90 and I-95 may see delays due to heat-related vehicle issues. Power companies are monitoring grid demand closely, with scattered outages possible.
The heat is expected to ease Thursday night, but additional advisories are possible if the pattern persists.
Warnings remain in effect until 7 p.m. Thursday. Updates will be posted if the advisory is extended or expanded.
