Riells is a small bay located on the Costa Brava in northeastern Spain, characterized by a southeast-facing coastline with a sandy beach and protected harbor area. The spot features a marina complex on the north side with extensive boat infrastructure, breakwaters, and mooring fields. The water body is a natural bay with moderate protection from the surrounding coastline and marina structures. Best conditions occur with northeast winds that provide side-shore conditions parallel to the beach. The shallow, choppy water and limited fetch make this primarily a beginner-friendly location. Wind reliability is low at 9.8%, suggesting inconsistent conditions typical of Mediterranean microclimates. The presence of significant boat traffic, moored vessels, and rock structures requires careful navigation. Average wave height of 0.75m indicates small swell, making this suitable for progression and flat-water practice rather than wave riding. The spot works best during thermal wind windows in summer months when local heating generates sea breezes.
