Oahu East Side Beaches

Sandy Beach has generally good water quality due to open ocean exposure and strong wave action that flushes the shoreline. Bacteria risk is moderate-low under normal conditions. However, Sandy Beach is one of the most physically dangerous beaches in Hawaiʻi — its powerful shorebreak causes more spinal cord injuries than almost any other beach in the state.

Makapuʻu sits at the far eastern tip of Oʻahu with strong open-ocean exposure and excellent natural flushing. Bacteria levels are typically low. Like Sandy Beach, though, the physical hazard is the primary danger: powerful shorebreak, strong shore dumps, and occasional rip currents make this beach unsuitable for casual swimmers. It's beloved by bodysurfers who know what they're doing.

Waimānalo Beach is a long, stunning stretch of white sand — one of the longest on Oʻahu — fronting the dramatic Koʻolau Mountains. Water quality is generally good with low bacteria risk under normal conditions. The beach is relatively uncrowded compared to South Shore and has a gentle, calm shore break suitable for families. The main water quality concern is runoff from the hills and nearby streams after heavy rain.

Bellows Beach is located on the grounds of Bellows Air Force Station and is open to the general public on weekends and holidays only. Limited access keeps it less crowded and better preserved than most public beaches. The water quality is low-risk with calm, gentle waves well suited for beginning bodysurfers and families. A beautiful, often-overlooked gem.

Kailua Beach consistently ranks among the best water quality beaches on Oʻahu. Calm, turquoise water, wide white sand, and a backdrop of the Koʻolau Mountains make it the most beautiful beach on the windward coast. It's excellent for swimming, kayaking, stand-up paddleboarding, and kitesurfing. The main post-rain concern is Kawainui Marsh drainage, but under normal conditions the water is outstanding.

Lanikai is a pristine, residential pocket beach adjacent to Kailua with some of the calmest, clearest water on Oʻahu. The offshore Mokulua Islands provide wind protection, and the shallow reef keeps the water calm even on trade wind days. Water quality is excellent under normal conditions. Note: Lanikai has no public restrooms and limited parking — access is through residential streets.
