Boston Declares Heat Emergency June 22-24 Amid Triple-Digit Forecast

Boston Mayor Michelle Wu has declared a heat emergency from June 22 through June 24, 2025, due to forecasted temperatures in the mid-90s with feels-like temperatures reaching up to 100 degrees. In response, the city has opened multiple cooling centers at Boston Centers for Youth & Families, Boston Public Library locations, splash pads, and city pools to help residents find relief. The heat emergency is driven by a heat dome affecting much of the eastern U.S., leading to increased emergency calls for heat-related illnesses, with Boston Emergency Medical Services expecting a 10 to 15 percent rise in 911 calls. Mayor Wu urged residents to stay hydrated, avoid leaving children and pets in vehicles, recognize signs of heat exhaustion, and check on neighbors and vulnerable populations. Worcester and other Massachusetts counties are also experiencing extreme heat watches, with cooling centers and spray parks available to residents. The city and state agencies are coordinating efforts to ensure public safety during this significant heat wave.
