Historical Poʻipū beach comparison; current DOH notices below take priority
The 1/5 ratings below are historical estimates. Check current notices above for each named beach and posted signs before entering the water.
Beach: Shipwreck Beach / Poʻipū Beach nearby
The Grand Hyatt fronts Shipwreck Beach, which has historically rated at low bacteria levels but has strong currents and shore break. For calmer water, guests use the hotel's saltwater lagoon or walk to nearby Poʻipū Beach Park. Historical ratings cannot describe today's water quality at either beach.
Beach: Poʻipū Beach Park
Koa Kea is in the Poʻipū resort area near Poʻipū Beach Park, a popular family beach with a protected cove and a lifeguard station. Its 1/5 bacteria risk estimate is historical; check the named current DOH notices above before planning to enter the water.
Both hotels have a historical 1/5 bacteria risk estimate, but Koa Kea is closer to Poʻipū Beach Park's protected family cove. The Grand Hyatt fronts Shipwreck Beach, which has strong currents and is not ideal for casual swimming — guests can walk to Poʻipū Beach Park or use the hotel's saltwater lagoon. The historical score is identical; current conditions can differ by named beach, so check the DOH notices above.
Water quality risk ratings are based on publicly available data from the Hawaii Department of Health Clean Water Branch, EPA impaired waters database, USGS stream monitoring data, and geographic analysis of pollution sources (streams, cesspools, storm drains). Ratings are estimates and may change with conditions.
