Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Europe/Amsterdam local. Folk tradition, not a scientific forecast.

Last spring tide on Thu 07 May (range 1.7m). Next spring tide on Mon 11 May (range 1.7m). Next neap on Wed 13 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Castricum aan Zee is the beach extension of the inland town of Castricum, reached by a 3-kilometre road and cycle path from the town centre, 15 kilometres north of Zandvoort. The resort is noticeably less developed than Zandvoort: fewer concessions, shorter rows of beach cabins, a longer stretch of unoccupied beach per visitor in high summer. Behind the dune foot, the Noord-Hollands Duinreservaat — one of the larger remaining dune nature reserves in the Netherlands — extends several kilometres inland and northward along the coast. The reserve serves three simultaneous functions: ecological habitat for dune vegetation, nesting birds, and rabbit populations; a protected freshwater aquifer (rainwater filtrates through the sand and is extracted by the Amsterdam and North Holland drinking-water utilities from wells sunk into the dunes); and a recreational walking and cycling area accessible via a network of paths from the beach and the inland villages. The interaction between these three functions is managed carefully. The ecological and water-extraction demands limit public access in certain zones; the walking trails thread between the restricted areas and give access to the dune interior. At the beach itself, the tidal pattern is the same as the rest of the North Holland coast: semidiurnal, with a mean spring range of approximately 1.8 to 2.0 metres. The beach faces west into the North Sea. The surf zone is broad at low water; the beach narrows as the tide floods and the dune foot becomes more exposed. Shore anglers here work the wet-sand face for flatfish — sole, plaice, and flounder — on the incoming tide, typically from the first two hours of the flood to mid-tide when the water is covering the lower-beach zone but before the upper beach drowns the casting distance. Autumn evenings on the incoming tide are the traditional flatfish session window on this coast. For families, the beach is a straightforward swimming shore in summer with lifeguard supervision; the generally lower crowd density relative to Zandvoort makes it easier to find space. Kite-flyers favour Castricum for the same reason: the afternoon onshore sea-breeze in summer and the autumn westerly sessions both work consistently on this open western-facing beach. Bird-watchers walking the dune reserve encounter migratory waders and passerines in spring and autumn, with the dune slacks providing freshwater habitat that draws species not found on the pure North Sea beach. The September–October migration through the North Holland dune corridor regularly produces unusual passerine falls when Atlantic low-pressure systems grounded birds moving south along the coast; Castricum is one of the recognised ringing-station locations for Dutch coastal migration monitoring. The inland village of Castricum is 3 kilometres east of the beach along the dune path or the access road; the combination of train connection (Castricum station, direct intercity service to Amsterdam and Alkmaar) and the beach road makes the beach accessible without a car from a wide catchment. The village holds the Nationaal Monument Psychische Gezondheid, a landmark building complex from the former Meer en Bosch psychiatric hospital dating to the early 20th century, now converted to mixed residential and creative use — visible from the dune path. The combination of the quiet beach, the large nature reserve, and the easy rail access makes Castricum a practical alternative to Zandvoort for visitors who prefer less crowd density without sacrificing the ease of a direct train from Amsterdam. The authoritative sea-level forecast for this section of the North Holland coast is Rijkswaterstaat (waterinfo.rws.nl); the nearest gauges are at IJmuiden to the south and Petten to the north. KNMI publishes the wave and wind forecast for the Dutch North Sea coast. Predictions on this page come from Open-Meteo Marine, a gridded global ocean model; accuracy is typically plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height.
