K4 (Sylt)

K4 (Sylt K4 / Bunker Hill) is a well-known wave kitesurfing and windsurfing spot on Sylt’s west coast near Hörnum. The wind is described as high reliability and often constant, with typical stronger directions from the South through West to North-Northwest (including S, SSW, SW, WSW, W, WNW, NW, and NNW). Typical wind ranges are around 12–21 knots, with a generally steady gust character. On the water, conditions are shaped by the North Sea and by strong tidal currents. Multiple sources flag strong currents and wooden stakes as key hazards, and explain that access and riding conditions can vary notably with tide. Water is commonly described as cloudy, with a sandy bottom and medium-sized sandy access/launch area. Low tide may expose flatter channels, but the area can still be hazardous and requires careful reading of conditions. For kitesurfing, the spot is characterized as advanced and primarily wave-oriented (also including freeride and downwinder use). Wind direction and strength make it a common starting point for downwind trips to Westerland in SW or SSW winds. Kite size ranges commonly cited are roughly 7–12 m², and the riding style fits experienced wave riders seeking powerful, non-trivial conditions. Safety and access rules are emphasized: riders should respect protected dune/nature reserve areas, use designated paths to reach the beach, and stay within designated riding zones. Restrictions around low tide are noted (commonly limited to a window of about two hours before and after low tide, with some notes allowing up to three hours). Rescue assistance exists, but rescue availability is described as limited at the spot level, so advanced preparation and conservative decision-making are important.
