Quintanamanil is a shallow lagoon system located on Spain's northern coast near the Bay of Biscay. The spot features expansive tidal flats with deep water channels winding through sand and mud banks, creating a complex shallow-water environment. The lagoon faces northward toward open water, with the eastern shoreline running roughly north-south along agricultural land. Wind conditions are marginal, averaging only 5.8 knots with very low reliability at 5.6%, indicating this is not a primary kitesurfing destination. Best wind direction would be from the east or west for side-shore conditions relative to the northern water exposure. Water temperatures average 10.5°C, requiring thermal protection year-round. The shallow, obstacle-laden nature and poor wind statistics make this spot most suitable for beginners on rare windy days, though consistent conditions cannot be relied upon. Kiters should carefully scout tidal heights and channel locations before launching, as extensive mudflats become exposed during low tide. Local knowledge of tidal cycles is essential.
