Officials are asking the public to stay out of these Los Angeles County beaches due to high levels of bacteria.

People who enter the ocean water during this period could become ill, especially children, the elderly, or those who are immunocompromised, said the L.A. County Department of Public Health.

Due to recent rainfall, excessive bacteria and debris can seep from nearby city streets and mountain areas, likely contaminating ocean waters around discharging storm drains, creeks and rivers, especially after rainstorms, officials said.

The public is advised to avoid swimming, surfing, and playing at these locations:

• Malibu Lagoon at Surfrider Beach – 100 yards up and down the coast from the public restrooms
• Latigo Shore Drive in Malibu – Entire swim area
• Escondido Creek at Escondido State Beach – Entire swim area
• Castlerock Storm Drain at Topanga County Beach – Entire swim area
• Santa Monica Pier in Santa Monica – 100 yards up and down the coast from the pier
• Brooks Avenue storm drain at Venice Beach – 100 yards up and down the coast from the storm drain
• Venice Pier in Venice – 100 yards up and down the coast from the pier
• Topsail Street extension in Venice – 100 yards up and down the coast from the Topsail Street extension.
• Redondo Beach Pier in Redondo Beach – 100 yards up and down the coast of the pier
• Mothers Beach in Marina Del Rey – Entire swim area
• Malaga Cove in Palos Verdes Estates – Entire swim area
• Inner Cabrillo Beach in San Pedro – Entire swim area
• Las Flores Creek at Las Flores State Beach – Entire swim area
• Puerco Canyon Storm Drain at Puerco Beach – Entire swim area

“These warnings have been issued due to bacterial levels exceeding health standards when last tested,” the health department said.

The public should also avoid contact with any runoff that may flow onto beach sand.

The ocean water warnings will remain in effect from Friday, Dec. 29, until Tuesday, Jan. 2, 2024, at 6 a.m. This advisory may be extended depending on further rainfall, health officials said.

A previous warning for these beaches was lifted after testing showed the water quality fell within safe standards:

• Walnut Creek at Paradise Cove
• Pico-Kenter storm drain at Santa Monica Beach – Santa Monica South Tower 20
• Windward storm drain at Venice Beach

The health department tests ocean water bacteria levels regularly and advisories will be lifted once the levels meet standards set by the state of California.

A dangerous high surf is also threatening SoCal beaches and coastal regions this week, prompting evacuation warnings. A massive rogue wave that slammed into Ventura beachgoers on Dec. 28 sent nine people to the hospital and left a trail of destruction in its wake.
