Chinaman's Hat (Mōkōli‘i)

Mōkōli‘i (Chinaman’s Hat) is a small, iconic basalt islet just offshore from Kualoa Beach Park on O‘ahu. It’s primarily known as a landmark, kayak/paddleboard destination, and scenic visit, but it can also produce an adventurous reef/point surf break when conditions align. The surf is exposed and very dependent on swell direction and wind. Winter swells from the north and east can make the paddle challenging, and trade-wind onshore flow often contributes to choppy water. When West or Southwest winds are rare, conditions can improve, but the riding areas remain generally exposed. Hazards are a major theme: the reef is shallow and sharp, with sharp coral/rocks and strong channel currents through the water between the mainland and the islet. Rip currents are common near reef edges, and there is a clear warning to avoid outgoing tide—especially when combined with strong wind—because wind against tide can create chop and drift. The spot is also within the wider Kaneohe Bay area where hammerhead sharks are reported, so staying alert in the water is important. Because this islets-adjacent surf involves a long transit and significant consequences if conditions shift, it’s best approached with advanced ability and careful planning. Wear water shoes, check tide and conditions before committing, and don’t go alone. Respect protective area rules for the sanctuary/islet access (including wildlife protection during nesting periods).
