Ocean Water Quality Rain Advisory A rain advisory is issued when there is significant rainfall that may cause bacteria levels in ocean waters to increase. Bacteria levels can increase significantly during and after rainstorms, as contaminants within the runoff enters the ocean. Bacteria levels may remain elevated up to 3 days depending upon the intensity of the rain and the volume of runoff. Elevated bacteria levels in ocean water may cause illness, especially in children and the elderly. The Department of Public Health recommends that beach users avoid contact with ocean water for a period of 3 days after significant rainfall, especially near flowing storm drains, creeks and rivers. An Ocean Water Quality Rain Advisory has been declared for all Los Angeles County beaches. The advisory will be in effect at least until 11:00 am, Monday, February 17, 2025. Beach users are cautioned to avoid water contact for at least 72 hours after significant rainfall. This advisory may be extended depending upon further rainfall. OCEAN WATER ADVISORY DUE TO FIRE IMPACTS: Once the rain advisory is lifted, the ocean water advisory from Las Flores State Beach to Santa Monica State Beach will remain in effect until further notice. Beach goers may recreate on the sand but continue to be advised to stay away from fire debris and to stay out of the ocean water during any posted ocean advisory. |

Water Quality Sampling
Laboratory results from three local agencies are displayed on the map. The Los Angeles County Department of Public Health (DPH) Environmental Health Recreational Waters Program, collects ocean water samples from the mainland, once a week throughout the year. DPH collects an additional five samples from Avalon on Santa Catalina Island beginning in April through October. The Los Angeles County Sanitation Districts (SD) collects ocean water samples at selected sites on the mainland, once each week throughout the year. The Beach Cities of Redondo Beach, Manhattan Beach and Hermosa Beach, Palos Verdes Estates and Rancho Palos Verdes (BC) jointly collect water samples within their cities, once a week throughout the year. DPH, SD, and BC also resample sites that have exceeded State Standards for bacteria in ocean water. The City of Los Angeles, Environmental Monitoring Division, LA Sanitation (HYP) collects water samples from various sites, one to five times per week, all year round. LA City also collects samples at some DPH sites as required by their State NPDES permit. The public is notified when a site has exceeded State Standards for bacteria in ocean water on this website, by telephone hotline, and by signs posted at the impacted beaches.
