Ría de Mogro is a tidal estuary and river delta on the northern coast of Spain (Cantabria region) where freshwater meets the Atlantic. The spot features a complex system of shallow channels, sandbars, and mudflats surrounded by agricultural land and a residential settlement. The coastline faces northwest toward the Atlantic, with the Mogro River creating a dynamic delta environment. The shallow, protected waters and variable depths make this suitable for intermediate kiters comfortable navigating around obstacles. Wind reliability is low at 6.5%, suggesting inconsistent conditions typical of protected estuarine spots. Northeast and southeast winds provide side-shore conditions, with northeast being more favorable for consistent Atlantic-driven patterns. Average 1.61m waves indicate modest swell penetration into the delta. Water type is rough due to tidal mixing and freshwater discharge. The spot requires understanding of tidal cycles, which significantly affect water depth and current patterns. Best conditions occur during neap tides with moderate offshore winds pushing through the delta channels.
