Stranded Humpback Whale 'Timmy' Resumes Swimming Off Germany's Baltic Coast

A humpback whale nicknamed "Timmy," which had been stranded off the island of Poel near Wismar on Germany's Baltic Sea coast, began swimming again on the evening of April 5, 2026, after days of deteriorating health and dwindling rescue hopes. Mecklenburg-Western Pomerania's Environment Minister Till Backhaus confirmed the development, crediting the decision to give the animal space and quiet. The whale initially moved in the wrong direction, heading toward the harbor, but water police later reported it was traveling seaward. The news came after experts had largely expected the animal to die in the bay following the suspension of active rescue attempts on Wednesday, April 1, 2026.

Humpback whales are deep-ocean mammals native to the North Atlantic and Pacific, rarely venturing into enclosed, low-salinity seas such as the Baltic. The Baltic Sea's salinity is significantly lower than that of the open ocean, making it a hostile environment for species adapted to saltwater conditions. "Timmy" had become stuck off the German Baltic coast four times since early March 2026, managing to swim free three times before ultimately stranding off Poel on Tuesday, March 31, 2026. The whale had previously been sighted in the port of Wismar and at Timmendorfer Strand in the state of Schleswig-Holstein before its final stranding.

Low salinity and propeller wounds pushed whale to the brink The whale's condition had been severely compromised by two compounding factors: the Baltic Sea's unusually low salt content and physical injuries. Backhaus stated on Easter Sunday that the Baltic's salinity is approximately one-third lower than what humpback whales are accustomed to in the North Sea or the Atlantic, causing serious skin problems that, in his words, "really influence the state of health very, very negatively." The animal also bore injuries consistent with ship propeller strikes, as well as marks likely caused by a net — wounds that only became fully visible as water levels dropped. Humpback whales are not adapted to the low-salinity, shallow conditions of the Baltic, making the stranding particularly dangerous. Marine biologist Tamara Narganes Homfeldt of the organization Whale and Dolphin Conservation had warned that in a large whale, the dying process can take several days, during which the pressure of the animal's own body weight progressively damages internal organs, ultimately leading to circulatory collapse and organ failure.

Fire crews sprayed water round the clock to ease the animal's pain Emergency personnel from the fire department monitored the whale continuously and regularly wetted its skin with water to reduce pain and lower surface temperature. Backhaus noted that thermal imaging data showed a marked difference between wetted and unwetted areas of the whale's body: where water was applied, surface temperature dropped significantly, while unwetted areas — kept dry to protect the lungs, nose, and blowhole — reached approximately 20 to 22 degrees Celsius. The positioning of the water sprinklers had to be adjusted multiple times due to shifting wind conditions on the Baltic coast, with the German Weather Service forecasting strong wind gusts on Easter Sunday. The whale had sunk 50 to 60 centimeters into the Baltic Sea floor under its own weight of approximately 12 tons. Backhaus ruled out euthanasia categorically, stating the animal would not be killed by any means. A demonstration took place in Wismar on Saturday, with residents expressing sympathy for the whale and calling for greater intervention, including the involvement of external experts.

Expert report due Tuesday as whale's fate remains uncertain Despite the encouraging movement on the evening of April 5, the whale's long-term prognosis remained unclear as of the latest reports. Backhaus said he expected a formal expert report from internationally recognized marine biologists and veterinarians on Tuesday, April 7, 2026, which would inform decisions on how to proceed. He confirmed he was also in contact with both the Federal Ministry of the Environment and the Federal Ministry of Agriculture regarding the situation. Active rescue attempts had been halted on Wednesday, April 1, after the whale became stuck for the fourth time, with specialists on site assessing that the animal would likely die in the bay. The renewed movement seaward offered a degree of cautious hope, though experts had not yet confirmed whether the whale had successfully navigated back toward open water. The water police continued to monitor the animal's trajectory as of Sunday evening.
