Waves breaking on sandy bottom, varied conditions
Hörnum Ost is located on the eastern coast of Sylt, a North Sea island off Germany's Schleswig-Holstein coast. The spot faces northeast into a shallow bay with mixed sand and rocky bottom. The water transitions from beach breaks to shallow bay conditions, creating variable ride characteristics. Wind reliability is moderate at 59.8%, with average winds of 14.2 knots—suitable for consistent sessions but not guaranteed. The average wave height of 1.11m indicates small, manageable swell typical of North Sea beach breaks. This spot is best suited for intermediate kiters due to shallow water, tidal influences, and uneven bottom features that require good board control. Northwest winds (315°) provide ideal side-shore conditions parallel to the coastline. Water temperatures average 10.7°C, requiring thick wetsuits year-round. The proximity to residential areas and visible infrastructure means the spot has limited space and moderate crowds. Best conditions occur during strong northwest wind periods when the bay provides protected, choppy water suitable for progression and freestyle practice.
