Sebatu sits outside Lagundri Bay in South Nias, facing the full Indian Ocean swell window and producing serious big-wave conditions. The wave is for committed big-wave chargers only, with heavy, hollow faces that can exceed 15 feet. Its open-ocean exposure means it picks up every swell that the bay misses, offering a completely different challenge to the point breaks inside Lagundri.
