Humpback Whale 'Timmy' Successfully Swims Free From Wismar Bay After Double Stranding

A humpback whale stranded twice in the Baltic Sea off the German coast swam free from Wismar Bay late on Monday, March 30, 2026, after rescuers used rising water levels and noise stimulation to coax the exhausted animal into motion. The whale, estimated at between 12 and 15 metres in length and nicknamed "Timmy" — after Timmendorfer Strand, the resort town where it first ran aground — had been lying largely motionless in roughly two metres of water for days, prompting growing concern among marine experts about its survival. After the animal dived on Monday evening, search boats found no trace of it overnight, but by Tuesday morning it had been spotted again in Wismar Bay, swimming freely. Greenpeace and the water police immediately moved to prevent it from re-entering shallow water near the harbour entrance of the island of Poel.

Two strandings, excavators, and a week of drama The whale had first been recorded in the Baltic Sea coastal area around March 3, 2026, drawing attention when it appeared in the harbour of Wismar. On March 23, it ran aground on a sandbank off Timmendorfer Strand in the state of Schleswig-Holstein, where an initial attempt to free it using a small suction dredger failed because the sand was too firm. Rescuers then brought in larger floating dredgers to excavate a 50-metre-long, 1.20-metre-deep channel in front of the whale's head. Marine biologist Robert Marc Lehmann approached the animal, which reacted with violent movements and snorting. During the night leading into Friday, March 27, the whale finally fought its way through the dug channel into deeper water. The relief lasted only briefly: by Saturday, March 28, it had stranded again, this time in Wismar Bay in the state of Mecklenburg-Western Pomerania, after swimming east rather than north toward the exit route.

Breathing rate halved, net remnants still in its mouth Throughout Monday, experts had described the whale's condition as seriously compromised. Burkard Baschek, the scientific director of the German Oceanographic Museum in Stralsund and the scientific coordinator of the rescue effort, said the animal had shown significantly less vitality, with vocalization, fin movement, and breathing all declining. He noted that when the whale was still off Timmendorfer Strand, it had been breathing two to three times per minute, but that rate had dropped to roughly once every four minutes by Monday. „It's not making any more noises. This lack of movement and reaction to our presence shows that it's simply very weak and getting weaker.” — Burkard Baschek via Deutsche Welle No tracking device had been attached to the whale because its skin was in poor condition following prolonged exposure to the low-salinity Baltic waters, which had also caused secondary infections. Remnants of a fishing net remained lodged in the animal's mouth, having only been partially removed during the Timmendorfer Strand operation. Baschek had earlier raised the possibility of euthanization if the whale reached a point where it had a clear chance to escape but was physically unable to take it, though he stressed that point had not yet arrived.

Greenpeace blocks harbour channel, long journey still ahead Till Backhaus, the environment minister of Mecklenburg-Western Pomerania, announced on Monday that a round-the-clock whale watch had been established to accompany the animal. „The calm that we gave the whale has paid off. It has built up enough strength to respond to the motivation through our boat and start swimming.” — Till Backhaus via Berliner Zeitung Greenpeace marine biologist Thilo Maack said the organization's inflatable boat was positioned to prevent the whale from entering the shallow, narrow channel at the harbour entrance of the island of Poel, and expressed hope that the animal would retrace the route by which it had entered the Baltic — north through Danish waters and then into the North Sea. Baschek, however, cautioned against any expectation of an escort over the several-hundred-kilometre journey, noting that the whale's ability to dive made sustained accompaniment impractical. „The whale swimming free yesterday is a first very good sign, but the way to the North Sea is still long and we can only keep our fingers crossed that it makes it there.” — Burkard Baschek via The Independent The nickname "Finn" had also circulated, reportedly stemming from an initial misidentification of the animal as a fin whale before it was confirmed as a humpback. Experts have not established a definitive explanation for why the whale entered the Baltic in the first place, with some suggesting it may have followed a shoal of herring or become disoriented during migration.

Humpback whales are not native to the Baltic Sea, which has a significantly lower salt concentration than the open ocean and the Atlantic where the species normally lives. The Baltic's restricted geography, with narrow exit straits between Germany, Denmark, and Sweden, makes it particularly difficult for large cetaceans to navigate out once they have entered. Whale strandings on the German Baltic coast are rare events and typically attract significant public and media attention. The species is known for long-distance migrations between feeding and breeding grounds, often covering thousands of kilometres.
