Wind Days = % of days with 12–35 knot average wind speed (ideal kiting conditions). Based on 4 years of historical weather data.
Partially sheltered coastline with moderate, varied conditions
Rantum Ost is located on the east coast of Sylt, a German North Sea island, forming a bay with consistent shelter from the dike system visible in the satellite imagery. The spot faces northeast into open water, providing moderate fetch from the North Sea. The bay configuration creates a contained riding area with a reinforced shoreline featuring industrial/port infrastructure. Water conditions show characteristic rough chop typical of the North Sea, with average waves around 1.1m and modest wind reliability at 50%. Best conditions occur with northwest to north winds (310-360°), which provide ideal side-shore angles. The spot suits intermediate kiters comfortable with tidal effects and variable water conditions. The dike protection reduces swell exposure but creates chop from localized wind patterns. Shallow areas near shore require attention to navigation. Water temperatures average around 10.5°C, necessitating thermal protection. The proximity to port facilities and boat traffic requires awareness of other water users. This bay offers a more protected alternative to exposed North Sea breaks while maintaining reasonable wind exposure.
