Plage Mateille is a shallow lagoon spot located in Gruissan, a coastal town on the Languedoc coast of southern France. The site sits between inland lagoons and open Mediterranean water, with northeast-facing orientation. The lagoon environment offers protected conditions with limited fetch and consistent chop rather than organized swell. Water depths vary significantly, creating uneven surface conditions typical of lagoon systems. A canal system and residential development border the spot, with boat traffic from the adjacent harbor present year-round. Wind reliability is moderate at 34.7%, with average winds of 10.4 knots and water temperatures around 16.5°C. Best conditions occur with northwest winds providing side-shore flow. The spot suits beginners and early intermediates seeking sheltered, shallow-water practice. Kiters should account for shallow depths, variable water conditions, and maritime traffic. The choppy water state (0.59m average) reflects the lagoon's enclosed nature rather than wave quality.
