Aarhus tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

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/Copenhagen local. Folk tradition, not a scientific forecast.

Next spring tide on Thu 21 May (range 0.5m). Next neap on Tue 19 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.

Aarhus sits on the western shore of the Kattegat, where Denmark's second-largest city meets a coast of moderate but real tidal movement. Mean tidal range here is approximately 0.4–0.5 m relative to MSL — enough to matter for harbour operations, kayak launches, and beachgoing, but far smaller than what you'd find on the North Sea side of Jutland. The tide is semidiurnal in pattern, meaning two high waters and two low waters per day, though the Kattegat's transitional position between the North Sea and the nearly non-tidal Baltic means the two daily cycles can be noticeably unequal in height. Wind and atmospheric pressure routinely add or subtract 0.3–0.5 m on top of the predicted tide; a sustained westerly over the Kattegat can push water levels well above predicted high water. The urban beach north of the harbour — stretching toward Riis Skov — is most accessible within two hours of low water when the sand is widest. Aarhus Havn handles significant commercial and ferry traffic; vessels working the harbour should treat tidal predictions as a baseline and monitor DMI's real-time water-level data, especially in unsettled weather. The ARoS art museum is visible from the waterfront, and the harbour's Dokk1 cultural centre sits right at the water's edge — both worth timing around a walk along the beach at low tide. DMI (Danmarks Meteorologiske Institut) issues official predictions; Open-Meteo Marine provides forecast modelling with typical accuracy of ±45 minutes on timing and ±0.2–0.3 m on height.
