About
Cotton Bay (Cas en Bas) is a reef-protected, crescent-shaped kitesurfing bay on Saint Lucia’s northeast Atlantic coast. The beach is large and sandy, with easy access and shallow, flat-to-small-wave water conditions inside the reef—making it well-suited for learning and freestyle progression. Wind is dominated by easterly trade winds, with the most favorable direction generally from NE (also reported as E/ENE). Typical speeds are around 15–25 knots, and wind reliability is described as high during the trade-wind season. The best months are reported as December through June/early July, with strong overlap in January–May for the most consistent riding conditions. Safety planning matters because the bay entrance and shoreline can involve reefs and rocks, and there are hazards like buoys and animals; sea urchins have also been noted in grassy walking areas. Respect any designated swim zones near beachfront areas and follow local guidance from the on-site kitesurf operations. Rescue availability is limited, so riders should be prepared to self-manage and stay within safe areas. Amenities are concentrated around the beachfront: restaurants and bars are available on site, and there are kite-focused services including schools, gear rental, and gear storage. Water temperatures are consistently warm (about 26–28°C year-round), and booties are recommended for beginners due to shoreline hazards.
