La Grande Côte is located on the Pertuis d'Antioche bay system on France's Atlantic coast near the Île de Ré. The coastline faces northeast toward open water, with a sheltered bay configuration and distinctive sandy beach backed by forested land and residential development. The spot consists of a moderate-width sandy beach with visible tidal flats and shallow water zones. Wind reliability is low at 23.1%, suggesting this location receives consistent but not powerful conditions. Average waves of 1.32m indicate small, manageable surf suitable for progression. The best wind direction is northwest (315°), providing side-shore conditions parallel to the beach. The sheltered bay environment and sandy bottom make this suitable for beginners and intermediate kiters seeking calm, predictable conditions. Key considerations include monitoring tidal changes affecting water depth and usable area, watching for overhead bridge clearance restrictions, and avoiding shallow flats during low tide. Water temperature averaging 13.8°C requires appropriate thermal protection year-round.
