Boston braces for dangerous heat through the July 4 weekend

Boston is under extreme heat as the holiday weekend gets underway. The City of Boston issued an excessive heat warning from Wednesday, July 1, through Friday, July 3, and the National Weather Service says the Boston Extreme Heat Warning runs through Saturday evening, July 4.

Forecast highs near 101 on Thursday and 104 on Friday could push heat index values to 112, making the commute, outdoor work, and holiday plans more dangerous than a typical summer stretch.

Where to cool off in Boston

The city says BCYF community centers, Boston Public Libraries, pools, splash pads, parks, and beaches can help residents cool down. Boston also says people who need help getting to a cooler space should call 3-1-1.

Who is most at risk

Boston officials say older adults, young children, people with disabilities, unhoused residents, and people with chronic conditions are at higher risk, but the warning applies to everyone. WBUR reported that roofers and a mail carrier were still working outside in the heat, underscoring how quickly heat can become a worksite problem. If you are outside on July 4, drink water, take shade breaks, and move plans indoors if you can.
