Tallinn 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.

Marine-conditions data not available for this station. Wind, swell and water temperature ride along with Open-Meteo Marine; gauge-only stations (e.g. UK EA Flood) publish water level only.

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

Tallinn faces the Gulf of Finland from the southern shore, a medieval city backed by limestone escarpment and fronting a harbour that has been one of the Baltic's busiest for eight centuries. The coastal regime here is defined not by the moon but by the wind: the astronomical tide in the Gulf of Finland is 5 to 20 centimetres — so small it rarely registers against the water-level variation driven by weather. On most days, the high and low shown on a tide table for Tallinn describe a signal buried inside the noise of pressure systems, wind setup, and the multi-day oscillations that slosh water back and forth along the 400-kilometre length of the Gulf. The physics are straightforward. The Baltic is an enclosed brackish sea with a narrow connection to the North Sea through the Danish straits; the gravitational tidal forcing that produces multi-metre ranges in the North Sea and along the Atlantic coasts dissipates almost completely by the time it reaches the inner Baltic. The Gulf of Finland is further enclosed still, and at Tallinn the mean astronomical range is effectively the lowest in Estonia's already microtidal coastline. What replaces the tide as the operative water-level driver is wind. A sustained westerly or southwesterly blowing across the Gulf for 36 to 48 hours — the prevailing direction in most weather patterns — pushes water progressively toward the east, raising levels along the Estonian and Finnish southern shores. Tallinn, on the south coast rather than the far end of the Gulf, sees a fraction of this effect; storm surges of 40 to 80 centimetres above mean are not unusual during strong westerly systems in autumn and early winter. An easterly reversal clears the water back westward and can drop the level below mean by a similar margin. For swimmers, the city's main beaches are at Pirita, east of the passenger terminal, and at Stroomi on the western side. Both face north across the Gulf of Finland, with the prevailing westerly fetch and some exposure to wind waves when the wind is from the north or northwest. The seasonal swim window runs June through August, when water temperature reaches 17 to 22 degrees Celsius on warm years. Jellyfish concentrations — primarily Aurelia aurita, the common moon jellyfish — are a summer fixture rather than a tide-dependent variable; they appear in calm, warm conditions regardless of water level. Kayakers launching from Pirita, the Kakumäe peninsula or the Rocca al Mare area navigate the open Gulf and the island chains toward Naissaar and Aegna. Wind direction and strength are the planning inputs that matter. The Gulf of Finland can develop a short, steep wind-wave with little warning when the fetch from the west or northwest is open, and sea kayakers here carry VHF radios and file float plans with local knowledge — the Baltic's brackish water temperature, even in summer, is a cold-water immersion risk if conditions deteriorate. Tide state is irrelevant to these plans. Shore anglers working the limestone ledge coastline west of Tallinn toward Keila-Joa target sea trout, pike-perch and perch. The fishing calendar here runs on water temperature and seasonal migration timing rather than tide: sea trout run in spring and autumn when the water cools below 12 degrees Celsius and the fish move inshore to spawn in the rivers. Photographers in the old town, at the Toompea viewpoint, and on the walls above the Lower Town plan for golden-hour light rather than any tidal window — the water level below the cliff is whatever the wind has set it to that day. Tide predictions on this page come from Open-Meteo Marine, with typical accuracy of plus or minus 45 minutes and 0.2 to 0.3 metres. At Tallinn, where the full astronomical range is 5 to 20 centimetres, the model uncertainty floor is larger than the signal being modelled. Treat the predicted highs and lows as indicative orientation rather than actionable data. The Estonian Weather Service (Ilmateenistus) publishes sea-level forecasts and storm-surge warnings for Tallinn Harbour at ilmateenistus.ee — this is the operative planning source for any water-based activity in the Gulf of Finland.
