West Flanders

West Flanders covers the entire 67-kilometre Belgian North Sea coast — the country's only coastal province, running from De Panne at the French border in the southwest through Nieuwpoort, Oostduinkerke, Koksijde, Middelkerke, Ostend, Bredene, De Haan, Wenduine, Blankenberge, the Zeebrugge port complex, and Knokke-Heist at the Dutch border in the northeast. It is one of the most continuously developed coastlines in Europe: a near-unbroken Zeedijk seawall and dyke promenade fronts the dunes and beaches from end to end, interrupted only by the harbour mouths at Nieuwpoort, Ostend, and Zeebrugge, and by the protected dune reserves at Westhoek (De Panne) and Het Zwin (Knokke-Heist). The tidal regime is fully macrotidal North Sea — semidiurnal, large, and the dominant coastal driver. Mean range along the Belgian coast runs from about 3.8 metres at Ostend to roughly 4.2 metres at Zeebrugge and 4.5 metres at Knokke-Heist near the Westerschelde estuary funnel; spring tides exceed 5 metres, and the wide intertidal sand flats expose hundreds of metres of beach at low water before the next flood begins. That scale is what makes the Belgian coast what it is: the wide flat strands at low tide host the kite landboarders, the horse-drawn shrimp fishermen at Oostduinkerke (a UNESCO-recognised tradition), and the family beach culture that defines the summer season. Vlaamse Hydrografie (Flemish Hydrography), the hydrographic arm of MDK (Maritieme Dienstverlening en Kust / Maritime Coastal Services), is the authoritative regional source — they operate the Ostend, Zeebrugge, Nieuwpoort, and Blankenberge tide gauges and publish official tide tables. For commercial port operations at Zeebrugge and Ostend, the harbour authorities and Belgian Navy hydrographic charts are the operational references. Gridded model predictions are well-suited to this coast: the model's typical height uncertainty (around 0.3 metres) is small relative to a 4-metre swing, so the rhythm and timing of high and low water on these pages are reliable for general planning, with the local Flemish Hydrography gauge for precise operations.
