Water quality, conditions, and what to know before you go
Lanikai is not a primary surf spot. Small wind swell provides occasional rideable waves for longboarders. The Mokulua Islands block some swell energy. Better surfing is available at nearby Kailua.
Minimal shore break most of the time. The beach is narrow and shallow near shore. Lanikai is more suited for swimming, snorkeling, and kayaking than surfing.
Lower bacteria risk than Kailua due to no direct stream outfall. Residential runoff is the primary concern after rain. Still avoid the water after heavy storms.
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 surfing. Runoff carries bacteria from land into nearshore waters.
When conditions are clear, Lanikai Beach has great options for surfing. Check the water quality above, then book with confidence.
