Heal the Bay 2021 Report Card: California’s Cleanest and Dirtiest Beaches

California’s drought has had one silver lining. Thanks in large part to a lack of rainfall, California beaches had “excellent” water quality in summer 2021, according to the newly-released 2020-2021 report card from Heal the Bay. 

Heal the Bay examined bacterial pollution levels for 500 beaches in the Golden State. An impressive 94% received an A or B grade.

There were 10 beaches that seriously underperformed. These “Beach Bummers” are ranked every year by Heal the Bay.

Headed to the beach this weekend? Heal the Bay has some tips to stay healthy. Don’t swim in the ocean 72 hours after a rain, stay away from enclosed beaches with poor water circulation, and keep 100 yards from storm drains, creeks and piers. 

Happy swimming!
