Cayeux-sur-Mer

Cayeux-sur-Mer is a kiteboarding-oriented beach in the Baie de Somme area, known for its very large tidal riding space and generally clean water. The coastline transitions from pebble surfaces at high water to extensive sandy areas with lagoon-like flats at low tide, which can dramatically change depth and riding feel across the day. Wind is consistently available from the west sector, with SW and NW described as best directions. Typical kite wind is reported around 10–25 knots (with one provider giving 15–25 knots) and reliability is described as steady/high in the main wind seasons (autumn and spring). Thermal reinforcement is described as rare in the wider region, so conditions are largely driven by Atlantic systems. For safety, the spot’s main warning is the groynes/breakwaters: they can be hard to see at high tide and can be deadly if you hit them or if lines snag. Combined with strong tidal currents during tide changes, this makes planning around tide tables and keeping clear of structures especially important. Additional care is advised for launching and landing on pebbles, particularly for beginners and riders setting up gear onshore. Kitesurfing is the best-fit discipline here, ranging from beginner-friendly flat water options (especially via lagoons/bassines at low tide) to more progressive conditions as water depth increases. Windsurfing and wingfoiling are possible, with wingfoiling becoming more practical at mid-to-high tide; at that point, groynes still require caution near shore. Surf exists only as a secondary/rare option with generally poor wave quality, mainly when NW/strong onshore events line up.
