Waves breaking on sandy bottom, varied conditions
Grenettes is a beach break located on France's Atlantic coast in the Vendée region, facing northwest toward the Bay of Biscay. The spot features a sandy beach with gradual offshore slope and visible sandbar formations that create wave structure. The coastline orientation (315°) indicates a northwest-facing shore, making northeast (45°) winds ideal for side-shore conditions. With average wind speeds of 10.8 knots and modest wave heights around 1.4m, this spot suits beginner to early intermediate kiters. Wind reliability of 32.4% suggests variable conditions requiring flexibility in session planning. The shallow sandbanks visible in satellite imagery provide natural protection but require awareness of changing water depth. The developed residential area immediately inland indicates moderate beach traffic, particularly during summer months. Best sessions occur during Atlantic swells with supporting northeast winds. Water temperatures around 14°C suggest seasonal variation with warmer conditions in summer months.
