Flensburg 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/Berlin local. Folk tradition, not a scientific forecast.

Flensburg sits at the top of the Flensburg Fjord on the German-Danish border, with Denmark visible from the city waterfront. The border is 7 kilometres north; the fjord runs another 40 kilometres south into the western Baltic. The city has been German since 1920 (before that it was Danish by culture and administration, and voted 75% to remain with Denmark in the 1920 plebiscite — outvoted by the surrounding rural districts), and the Danish heritage is still visible in the shopfronts, the language mix on market day, and the red-brick merchants' houses of the old harbour. Tidal range at Flensburg is negligible — 0.1 metres or less, deep inside the Baltic basin where gravitational tides are barely measurable. Wind surges can raise or lower the fjord level by 0.5–1.0 metres, but the narrow fjord geometry provides significant shelter from open-water Baltic swells. The result is a waterway with reliably calm conditions — the fjord was historically the safest approach anchorage on the German Baltic coast, and it was used by the German Navy as a refuge in both world wars. The fjord is the activity centre. Sailing, kayaking, and SUP all work in the flat, sheltered water. The fjord narrows progressively toward Flensburg; the lower reaches near the Danish border town of Glücksburg have several bathing beaches, including Wassersleben and the Glücksburg castle approach (a moated water-castle, one of the best preserved in Northern Europe). The Flensburg inner harbour has been converted to a cultural waterfront with restored merchants' warehouses, a rum museum (Flensburg was the historic centre of rum importing in Northern Europe), and active ferry service to Glücksburg and Danish ports. The rum tradition is local identity: Flensburg was the primary Baltic port for Caribbean rum imports from the eighteenth century, and the Hansen Rum distillery and museum on the inner harbour documents the trade. The Rumflasche (Flensburg rum flask — a distinctive ceramic bottle) is the region's most recognised souvenir. A guided tasting at the museum takes 60 minutes and explains the Caribbean connection to a northern port city. Cycling north to Denmark on the Gendarmenpfad trail (Customs Officer's Path, running through the borderland between the two countries) is the standard day trip — the 50-kilometre marked route follows the fjord east shore from Flensburg to Padborg and can be ridden in a day. Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge.
