Tide Table Den Helder — 2026

📘 About Den Helder Tide Forecast

Located in Netherlands, Den Helder sits at latitude 52.97° North and longitude 4.75° East. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 1.1m and spring tides reaching up to 1.5m. This location sits on the edge of the Wadden Sea (Waddenzee), a UNESCO World Heritage natural site, a region of extensive sand and mud flats exposed between the barrier islands and the mainland at every low tide. The intertidal zone hosts benthic communities adapted to moderate salinity and temperature swings across tidal cycles. The semi-diurnal cycle flushes coves frequently, shortening water residence time and maintaining high oxygenation levels. Data from this station feeds into the global sea-level monitoring network, contributing to long-term change research.
