For a stretch of mid-to-late August, Waikīkī Beach becomes an open-air stage for ocean sports. Duke’s OceanFest is the annual tribute to Duke Paoa Kahanamoku, with amateur ocean-sports events, volleyball, and community gatherings centered around the Waikīkī shoreline. The Outrigger Duke Kahanamoku Foundation lists Duke Kahanamoku OceanFest on its 2026 events calendar, and the official OceanFest site says the event returns August 14-24, 2026.

The day-by-day 2026 schedule is the part to verify close to travel. The official OceanFest homepage still needs a final pass, and some sponsor and event pages continue to show older-year details. Use this guide for the planning window, then confirm the final heats, registrations, and exact venues on the official links before you build a paid day around a specific event.
