More than a dozen Massachusetts beaches closed as temperatures heat up

More than a dozen beaches in Massachusetts are closed to swimmers on Thursday due to bacteria concerns as “feels-like” temperatures near 100 degrees.

As of Thursday afternoon, there were 14 beaches, lakes, and ponds closed, according to the Massachusetts Department of Public Health’s interactive beach water quality dashboard.

Nearly all of those bodies of water are closed due to harmful bacteria levels, the dashboard indicated.

The dashboard is updated hourly between 8 a.m. and 5 p.m. each day.

The water quality at beaches in Massachusetts is required to be monitored. This monitoring data helps local health officials determine when to close a beach due to unsafe conditions and notify the public so that beach visitors can make informed decisions about swimming at the beach.

Swimming in unsafe waters can result in gastrointestinal and respiratory health issues.

The state conducts weekly water quality testing at the start of each week from Memorial Day through Labor Day.

Below is the current list of active closures shown in the dashboard:
