About
Sanghyang Island is a remote, boat-access-only surf spot in the Sunda Strait, known for a right-hand reef-coral break with world-class/excellent wave quality. The wave has good clarity and can work from small swells (under about 1 m) up to roughly 2 m+ (some reports extend higher). Sessions generally depend on having the right swell direction (southwest) and getting the tide timing right, with rising and falling tides specifically emphasized. The break is exposed and takes place over a shallow, sharp coral/reef bottom with sea urchins. Hazard risk is a major theme across sources: coral cuts, urchins, and submerged rocks make wipeouts and bad landings potentially dangerous. Strong tidal currents in the Sunda Strait can also add difficulty, and there is no dedicated on-island rescue base; emergency response is managed from the mainland. Seasonally, the best window is reported as May through September (dry season), with July–September commonly highlighted in regional wind patterns. Water temperatures stay warm year-round (reported around the high 20s °C), so reef/skin protection is still recommended to reduce sun and cut risk. Facilities are minimal on the island: there’s no food available on-island and limited/no on-island equipment rental or repair support. Visitors typically arrange boat transport from Anyer or nearby departure points and plan to bring all essentials, including water and a first aid kit for reef-related injuries.
