Indicators

South Nias, Indonesia
🪸Sharp reef😮‍💨Hold-downs

Indicators is a world-class right reef break at Lagundri Bay in South Nias, located around the point from the famous Sorake Beach. The wave produces incredible barrels when a solid SW swell pushes in at high tide, but becomes extremely dangerous at low tide when the reef is exposed. The rising high tide is the sweet spot—when Indicators turns on, it rivals any right-hander in Indonesia for raw barrel quality.
