Post-Rain Hazards at Southern California Beaches
Following recent rainfall, the Los Angeles County Public Health Department has issued a warning for beachgoers to avoid contact with ocean and bay waters due to contamination risks. The rain has caused runoff from city streets and mountain areas, introducing bacteria, chemicals, and trash into the water. These hazards are particularly acute near storm drains, creeks, and rivers. The advisory is in effect until 8 a.m. Wednesday, April 22, 2026, as dry and warm weather is expected to return after Monday.
