Ocean waters along the Orange County coastline (including the bays and harbors) are monitored for indicator bacteria at least weekly year around to determine compliance with swimming standards. The Orange County coastline is safe for swimming. However, beach goers should avoid the water near discharging storm drains, creeks and rivers, and avoid contact with any runoff on the beach. During the rainy season, swimmers should avoid ocean waters near discharging storm drains, creeks and rivers for at least three days following the end of the rainstorm. In the event of a sewage spill, Environmental Health will formally close the beach by posting closure signs along the affected beach area.
