Boa

Rote Island, Indonesia
🪸Sharp reef

Boa is a quality right reef break on Rote Island that produces standout barrel sessions when conditions align. The key to scoring Boa is timing—it needs a specific combination of swell direction and tide to fire, making a local surf guide invaluable. When it's on, Boa delivers multiple barrel opportunities per wave, rivaling any right-hander in the eastern Indonesian archipelago.
