Sapinus is a reef-based kitesurfing spot located in French Polynesia's lagoon system, featuring an exposed coral reef structure visible as the darker turquoise area in the satellite image. The coastline faces west toward the water, with developed residential areas immediately inland. The spot is characterized by shallow lagoon waters with complex reef topography and a defined reef edge where white water indicates breaking waves. The area experiences consistent but low-velocity wind (6.7 knots average) with poor reliability at only 19.8%, making sessions unpredictable. Wave heights average 1.69m, indicating generally small swell. Northerly winds provide side-shore conditions. This spot suits advanced kiters comfortable navigating reef hazards, sharp coral, and shallow-water obstacles. The rough water conditions suggest turbulence from reef-induced currents. Key considerations include tide timing to avoid extremely shallow sections, reef awareness for board/line management, and waiting for wind conditions above the low average. The low reliability and technical reef environment make this unsuitable for beginners or intermediate riders.
