Water quality & family beach guide near Līhuʻe
📍 Hanamaulu, Kauaʻi — Local park with pavilions & camping
Hanamaulu Beach Park has moderate water quality. The Hanamaulu Stream drains agricultural and residential land and empties into the bay, creating elevated bacteria risk after rain. During extended dry periods, the historical risk may be lower than immediately after runoff, but that is not a same-day water-quality result. The DOH monitors this beach and issues advisories periodically — more frequently than south shore beaches due to Kauaʻi's higher rainfall.
Based on: Hanamaulu Stream discharge, DOH monitoring history, Kauai east-side rainfall patterns
Hanamaulu Stream drains into the south end of the bay. After rain, use 48-72 hours as the starting range, with 72 hours or longer as the cautious default for heavy rain, brown or murky water, posted advisories, and the stream-mouth area. Use the live DOH box above, posted signs, water color, and local guidance before ocean plans.

Covered pavilions, restrooms, outdoor showers, parking lot, and grassy picnic area.
