The German Baltic Sea is full of surprises — and sometimes visitors appear that nobody expected. All of Germany is currently talking about Timmy, a humpback whale stranded in the Bay of Wismar since late March 2026. But Timmy is no isolated case: on 14 April 2026, a beluga whale was spotted in the Flensburg Fjord — right in our neighbourhood. And the resident harbour porpoises can be seen in the Fjord all year round. A look at the fascinating world of whales and dolphins in the Baltic Sea.
Humpback whale Timmy — the drama off Wismar

In late March 2026, a young humpback whale was spotted in the Bay of Wismar. He was quickly named Timmy and became a media sensation. The whale, probably a young male, had strayed into the shallow waters off the island of Poel and could not find his way back to the open sea. Despite intensive monitoring by marine biologists, the Environment Ministry of Mecklenburg-Vorpommern and Greenpeace, Timmy was unable to free himself. His health deteriorated visibly — his breathing became shallower, with no signs of stabilisation. Timmy's fate has moved the entire nation and raises the question: what brings whales to the Baltic Sea? Humpback whales normally inhabit the open oceans, migrating between Arctic feeding grounds and tropical breeding areas. Their straying into the comparatively shallow and low-salinity Baltic is rare — but it happens again and again.
Beluga whale in the Flensburg Fjord — April 2026

Just days after the peak of the Timmy drama, another report made headlines: on 14 April 2026, a beluga whale was apparently spotted in the Flensburg Fjord. The sighting was reported by the Nordschleswiger, TVSyd and numerous German media outlets. A completely white whale in the bay near Flensburg — an extraordinary spectacle. Beluga whales, also known as white whales, normally inhabit Arctic and sub-Arctic waters off Greenland, Canada and Russia. As early as 2012, a beluga measuring around 4.50 metres was seen in the Flensburg Fjord — the first time in 42 years. The current sighting is therefore extremely rare and shows just how close the Arctic can feel on the Flensburg Fjord. For guests at Villa Boreal, this means: sitting on the private jetty or the veranda, you could theoretically see a beluga gliding past.
Harbour porpoises — the whales on our doorstep
While humpbacks and belugas are rare vagrants, harbour porpoises (Phocoena phocoena) are a permanent part of the Baltic ecosystem. They are Germany's only native whale species and, at up to 1.80 metres, the smallest cetaceans in European waters. In the western Baltic, particularly in the Flensburg Fjord and around the Holnis peninsula, porpoises can be spotted regularly. Also known as 'little tumblers', they feed on small schooling fish such as herring and sprat. Unlike dolphins, porpoises are rather shy and usually reveal themselves only through brief surfacings to breathe. With patience — and the right vantage point — they can certainly be observed. The western Baltic population is considered endangered: bycatch in gillnets, underwater noise and pollutant contamination all take their toll. Every sighting is therefore all the more precious.
Dolphins in the Baltic Sea — rare visitors

Dolphins too occasionally stray into the Baltic. Bottlenose dolphins (Tursiops truncatus) and white-beaked dolphins have been reported in the western Baltic and even in the Flensburg Fjord in recent years. These sightings are rare, but they underscore the Fjord's importance as a diverse marine habitat. Unlike porpoises, dolphins are easier to spot — through their leaps, playful behaviour and distinctive dorsal fin. Those who go sailing or cruise the Fjord by boat have the best chance of an encounter.
Why do whales come to the Baltic Sea?
The question has occupied marine biologists for decades. The Baltic is an enclosed sea with low salinity — not an ideal habitat for large whales. Yet several explanations exist: young, inexperienced whales follow fish migrations and lose their bearings. Climate change alters currents and water temperatures, potentially favouring unusual migration routes. The Flensburg Fjord, as a narrow arm of the sea, acts as a natural funnel — once a whale has entered, finding the way back to open water can take time. And improved water quality in the western Baltic is attracting more fish, which in turn draws marine mammals.

Anyone who wants to observe porpoises — or, with a lot of luck, even larger marine mammals — will find ideal conditions on the Flensburg Fjord. The quiet coastline between Holnis and Bockholmwik offers unobstructed views across the water. The private jetty at Villa Boreal is right on the water — a perfect vantage point in the early morning hours or at sunset. Sightings are also possible from the beach at Bockholmwik, from the Glücksburg pier or during a sailing trip. Binoculars and patience are the most important tools.
A sea full of surprises
The Baltic Sea is more alive than many think. Whether it's humpback Timmy, the white beluga in the Flensburg Fjord or the resident harbour porpoises — the coast near Glücksburg offers nature experiences you wouldn't expect.
