Water quality, conditions, and what to know before you go
Waikiki has a gently sloping sand bottom with a protective reef that keeps larger waves offshore. The nearshore area stays shallow for an extended distance, making it one of Hawaii's most family-friendly beaches.
Children are more susceptible to waterborne illness than adults. The Ala Wai Canal can discharge bacteria after rain that is particularly concerning for young swimmers who frequently swallow water. Avoid the water for 72+ hours after heavy rain.
Lifeguards are stationed along Waikiki Beach daily. Multiple lifeguard towers cover the stretch from Duke Kahanamoku Beach to Queen's Beach. Facilities include restrooms, showers, and changing areas.
Extensive facilities: restrooms, outdoor showers, shade structures, nearby food options, rental shops for floats and water toys. The Waikiki Aquarium and Honolulu Zoo are nearby for non-beach activities.
The Hawaii Department of Health recommends staying out of the ocean for at least 72 hours after heavy rain. This applies to all ocean activities including swimming with kids. Runoff carries bacteria from land into nearshore waters.
When conditions are clear, Waikiki Beach has great options for swimming with kids. Check the water quality above, then book with confidence.
