About this spot

The Emerald Sea is a large shallow lagoon behind the outer reef north of Ramena, reached by boat. In the Varatraza season (about April to November) the south-east trade wind blows over flat, turquoise water inside the reef.

Riding here is usually done on guided boat trips or downwinders from the kite camps. Stay inside the reef, ride with boat support, and be ready for strong wind.

Amenities

  • Guided boat trips from the kite camps

Needs local verification: Compiled in October 2026 from independent spot guides and the general descriptions of the Diego Suarez kite camps. Access, boat transfers and school operations change, so everything here needs confirming locally; coordinates are approximate, not verified launch points. No verified live webcam was found, so the camera links open Windy's webcam search instead of a local feed.

Local hazards

  • Boat access only — ride with support
  • Outer reef and breaking waves
  • Very strong wind in peak season
