Grenaa 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 Wed 13 May (range 0.6m). Last neap on Thu 07 May. Next neap on Mon 11 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.

Grenaa occupies the outer Kattegat coast at the northern end of Djursland — more exposed than Ebeltoft to the south, with a mean tidal range of approximately 0.4 m. Two tides per day, broadly semidiurnal, though the Baltic's dampening influence keeps the range modest compared to the open North Sea. The harbour is the departure point for ferries to Anholt island (roughly 40 km offshore, a two-hour crossing) and to Varberg on Sweden's west coast — making tidal and weather awareness directly relevant for anyone planning those passages. Anholt's ferry schedule is limited (typically one or two sailings per day in season), so missing it because of an unexpected tidal or weather delay has real consequences. The outer coast north and south of Grenaa town features long stretches of beach backed by dunes — some of the longest and least-crowded sandy shoreline in the Central Jutland region. At low water the foreshore expands noticeably, though the 0.4 m range means the difference is visible rather than dramatic. Wind from the north or northeast accelerates down the Kattegat's fetch and is the dominant meteorological influence on actual water levels; surge events of 0.3–0.5 m above prediction are possible in sustained northerly winds, affecting both harbour operations and beach safety. Grenaa Strand beach directly north of the harbour is the most popular swimming spot; sheltered enough for families in most conditions but open enough to feel the full Kattegat swell in a northerly blow. DMI (Danmarks Meteorologiske Institut) provides official predictions; Open-Meteo Marine models forecast conditions with typical accuracy of ±45 minutes on timing and ±0.2–0.3 m on height.
