Formerum Terschelling

Formerum on Terschelling is a sheltered lagoon spot located behind coastal dikes on the northern Dutch island. The water body is enclosed with a sand/mud bottom typical of Wadden Sea formations, creating warm, shallow conditions. The lagoon orientation runs northeast to southwest with protection from the dike system on the western shore. Wind reliability at 57.4% and moderate average wind of 14.1 knots make this suitable for consistent but variable sessions. The small wave average of 0.97m reflects the protected lagoon environment. This spot is ideal for beginners and progression riders due to flat water and light winds. Key considerations include tide management—water depth varies significantly with tidal cycles, requiring awareness of shallow areas and mudflats. The enclosed nature provides safety but limits wave development. Best conditions occur with northeasterly or southwesterly winds that provide side-shore flow. During neap tides and moderate wind days, the lagoon becomes manageable for skill development and freestyle practice.
