LA County issues water quality warning for local beaches after rain

Following the recent heavy rain on April 12–13, 2026, the Los Angeles County Department of Public Health has issued an important Ocean Water Quality Rain Advisory.

This alert covers all local beaches and serves as a vital reminder for residents and visitors to stay safe.

When it rains, water flows over city streets and hills, picking up bacteria, chemicals, and trash.

This polluted runoff is then carried into the ocean through storm drains and creeks.

Contact with this water can cause serious health issues, including gastroenteritis, skin rashes, and ear infections.

Experts urge the public to avoid swimming, surfing, or wading for at least 72 hours after the rainfall ends.

While the advisory was set to expire on April 15, officials remind the public that it could be extended if more rain falls.

Children, the elderly, and those with weakened immune systems are at the highest risk.

Always prioritize your health and stay out of the water after a storm.
