Les Rosaires is a beach break located on the Brittany coast of France, oriented toward the northeast. The spot features a long sandy beach backed by residential development and forested areas, with tidal mudflats extending into the bay. Water conditions are typically choppy rather than wave-focused, making this primarily a wind-sport rather than wave-sport venue. The limited fetch and enclosed nature of the bay result in small average wave heights of 0.54m. Best wind conditions occur from the northwest (315°), providing side-shore winds parallel to the coast. With average wind speeds of only 9.5 knots and reliability below 25%, consistent conditions are rare. The spot suits beginners due to flat water and minimal wave hazards, though low wind frequency requires patience. Key considerations include tidal movements affecting water depth, proximity to residential areas limiting session duration, and the need to watch for occasional boat traffic. Summer offers better accessibility, though thermal winds remain weak.
