BOSTON – Looking to head to the water and cool off this July 4th holiday weekend? First, make sure to check the list of Massachusetts beaches that are closed to swimming.
The Department of Public Health publishes a daily water quality dashboard to let residents know which beaches are closed for the day due to bacteria or other reasons. It is updated at 9:30 a.m. and 12:30 p.m. every day during beach season.
“If a beach is closed, do not swim or enter the water at that location to avoid risk of illness,” the department says.

Why are beaches closed in Massachusetts?
“Bacterial exceedance” is the most commonly listed reason for closure. Experts say this is caused by runoff pollution or sewage overflows following heavy rain.
Sometimes beaches are closed because of a “harmful cyanobacteria bloom,” also known as blue-green algae.
Swimming in water with excessive bacteria can caused gastrointestinal and respiratory issues, as well as skin rashes, itching and earaches.
