50+ Massachusetts beaches closed for swimming by Department of Public Health. See where

As we enter the last stretch of summer before school starts, there is no better way spend a day than relaxing at one of the Bay State’s beautiful beaches.

However, the number of closed beaches in Massachusetts keeps getting higher. This weekend, over 50 beaches are closed due to unsafe swimming water.

The Massachusetts Department of Public Health (MDPH) states that swimming in the water at these closed beaches poses a threat of illness due to high levels of bacteria. Symptoms can range from nausea and vomiting to a sore throat and fever.

Here’s a full list of closed beaches to avoid when planning your weekend.

Those in the “other” category can be closed due to a variety of chemical or physical hazards, such as riptides and poor visibility.

Beach weather this weekend: AccuWeather warning about rip currents developing this weekend from storm off coast

When will beaches in Massachusetts re-open?

According to the MDPH website, beaches can only re-open when their bacteria levels are back within the safe range, so there is no set amount of time for a closure.

The status of a closed beach can be checked on the website’s water quality dashboard, which is updated at 9:30 a.m. and 12:30 p.m. daily.

National Hurricane Center cautioning beachgoers in the Atlantic

Forecasters are warning beachgoers about possible “life-threatening surf and rip current conditions” this weekend because of Hurricane Ernesto. The storm is not predicted to make landfall in New England.

“Even if Ernesto stays well offshore of the U.S. East Coast, beach goers should be aware of a significant risk of deadly rip currents beginning later this week,” the National Hurricane Center said earlier this week.

Riptides or rip currents are powerful currents of water that can pull people away from shore, according to the National Weather Service. They can be deadly: data from the NWS shows rip currents have killed almost 30 people this year alone.

If caught in a rip current, the NWS says to yell for help and remain calm and stay afloat while waiting for help. Do not swim directly against a riptide, rather swim parallel to the shore.
