Each year, from late October through mid-January, the fjords around Tromsø become one of the best places in the world to observe whales in their natural environment. This seasonal gathering is tied to the annual migration of Atlantic herring, which move into the sheltered coastal waters of Northern Norway to overwinter.
The large shoals of herring attract several species of whales, most notably humpback whales and orcas, who follow the fish to feed intensively in the narrow fjords and bays.

Feeding season
The main feeding season typically begins in late autumn and peaks in early winter. The whales are most active in the fjords north and northeast of Tromsø, such as Ullsfjorden and Kvænangen. These areas offer both the rich feeding grounds and the deep, calm waters that whales prefer.

Humpback whales are among the most commonly sighted species. Known for their acrobatic behavior and long pectoral fins, they can often be seen lunge-feeding or diving with a characteristic tail-fluke splash.

Orcas (killer whales) also follow the herring, hunting in groups and sometimes using cooperative techniques to herd fish into tight balls.

Fin whales, sperm whales and minke whales are occasionally spotted during the same season, although less frequently and often farther offshore.

Whale watching in the Tromsø region
The concentration of whales close to shore in the fjords of Troms county is unusually big and provides a unique opportunity for observation. The steep-sided fjords allow boats to get close to the action while still maintaining safe and respectful distances. Because the whales are in the area to feed, their behavior can be active and social—especially during the brief twilight hours of the Arctic day.

Ocean Sherpa Expeditions organizes multi-day whale-watching cruises. This enables us to spot the whales, have time to follow them at a respectful distance, and enjoy their company without any other disturbances.
