Water quality status and bacteria risk rating
📍 East Kauaʻi, Hawaiian Home Lands community
Anahola Beach Park on Kauaʻi's East Side has generally good water quality under dry conditions. Open ocean exposure provides decent flushing, and the beach is set in a largely rural area with less urban development than other parts of the island.
The main water quality concern is the Anahola Stream, which empties into the ocean at the north end of the beach. After rain, this stream can carry elevated bacteria levels from upstream agricultural and residential areas. The East Side of Kauaʻi receives moderate rainfall, making stream-related runoff a recurring consideration. Swim away from the stream mouth, especially after rain.
Based on: DOH monitoring, Anahola Stream runoff potential, East Side rainfall patterns, open ocean flushing
The Department of Health recommends staying out of the ocean for at least 72 hours after heavy rain. Anahola Stream can carry significant runoff into the beach area after storms. Avoid swimming near the stream mouth at the north end of the beach after any rain. Always check the water visually before entering.
