Boston, MA – Main streets across Massachusetts are heating up as highs climb into the mid-80s today, with a surge of heat and humidity arriving Thursday and peaking Friday when a Heat Advisory will go into effect.
According to the National Weather Service Boston, residents should expect mainly sunny skies and highs ranging from 80 to 85°F Wednesday, with temperatures expected to rise even further Thursday and Friday. The advisory warns of dangerous heat indices, especially for cities like Boston, Worcester, and Lowell, where Friday’s highs could reach 92°F.
Communities along I-90 and I-495—including Framingham, Lawrence, and Brockton—will feel the heat intensify by Thursday afternoon. Those in coastal towns from Plymouth to Gloucester should also prepare for muggy conditions, while Cape Cod and the Islands remain slightly cooler but still warm.
Health officials urge residents to limit outdoor activity, drink extra water, and check on elderly neighbors and pets. Air-conditioned spaces and cooling centers may be available for relief. With humidity increasing, the risk of heat-related illness will rise, particularly during peak afternoon hours.
The Heat Advisory remains in effect through Friday evening, with more updates expected as the week progresses. Stay tuned for any additional advisories or warnings as conditions develop.
