Vairao is a protected lagoon spot on Tahiti's south coast, characterized by shallow turquoise waters enclosed by a coral reef system. The coast faces northwest, with dense tropical forest backing most of the shoreline. The lagoon offers enclosed, relatively calm waters compared to ocean breaks, making it suitable for learning and progression. Wind reliability is low at 20.8%, suggesting inconsistent conditions typical of protected lagoon environments. Best wind direction is easterly (side-shore), though prevailing trade winds in this region are variable. Water temperatures average 24.8°C year-round. The spot features moderate wave energy (1.67m average) generated within the lagoon rather than direct ocean swell. Limited infrastructure and residential access points constrain launch and landing areas. Hazards include shallow coral patches, reef structures, and variable bottom composition. This spot suits beginners and intermediates seeking protected conditions with manageable wave heights, though low wind reliability and limited space require careful planning. Local knowledge of tidal flow through reef passages is essential.
