Los Angeles beachgoers beware: the Department of Public Health is waving a red flag at several popular coastal spots. Officials have slapped a stern warning for those looking to dip in the waters near some beloved beaches, advising against any swimming, surfing, or frolicking due to unhealthy bacterial levels.

The no-go zones include Inner Cabrillo Beach in San Pedro, and know that Malibu Lagoon at Surfrider Beach is not exempt; 100 yards on either side of the public restrooms are off-limits, as is the entire swim area at Mothers Beach in Marina Del Rey, add Santa Monica Pier in Santa Monica to the list, which boasts a warning for 100 yards both ways from the pier and let's not forget Santa Monica Canyon Creek at Will Rogers State Beach, where a cautionary radius extends 100 yards from the creek. This bulletin comes straight from the folks at the County's public health advisory, who regularly test these areas to ensure they're safe for public enjoyment.

On a brighter note, it's not all gloomy for the county's shores. As per the latest samples, water quality levels have bounced back to within State standards at a couple of previously troubled spots. The Temescal Canyon storm drain at Will Rogers State Beach and the Pico-Kenter storm drain at Santa Monica State Beach, specifically Santa Monica South Tower 20, are now deemed clear for water activities.

For those who like to be in the loop, the County provides around-the-clock updates on beach conditions through their hotline at 1-800-525-5662, and for the map fanatics or anyone in need of more detailed information, all of this can be found with a simple click to their website.
