Also known as Kaimana Beach — water quality and safety guide
📍 East Waikiki, near Kapiʻolani Park and Diamond Head
Sans Souci Beach consistently earns the best water quality ratings of any Waikiki beach. Its position at the east end of Waikiki — far from the Ala Wai Canal outflow — means it avoids the primary source of post-rain bacteria that affects central Waikiki. The natural reef acts as a partial barrier and the area has minimal nearby stormwater infrastructure.
The DOH has historically noted fewer advisories for this stretch than for beaches near the Ala Wai outfall. It is widely considered the cleanest swimming beach within Waikiki proper. Even so, conditions can change after significant rain or following a major storm event.
Based on: DOH Waikiki monitoring, distance from Ala Wai Canal, protective reef, minimal stormwater inputs
The DOH recommends staying out of the ocean for at least 72 hours after heavy rain. Sans Souci is more resilient than other Waikiki beaches, but strong storms can still affect the area. When in doubt, wait it out.
