Do Orcas and Humpbacks Come to Tromsø Every Winter?

If you’re planning a winter trip to the Arctic, one of the biggest questions you might have is:
“Do orcas and humpback whales actually return to Tromsø every winter?”

The short answer is:
✔ Yes — most winters
✔ But not always in the same numbers
✔ Because their migration depends on one thing: herring

Let’s break it down in a simple, science-based way so you know exactly what to expect from whale watching in Tromsø.

Why Orcas and Humpbacks Come to Tromsø

Every winter, huge shoals of Norwegian spring-spawning herring gather in the fjords and coastal waters around northern Norway.
This herring migration is the single biggest reason orcas in Tromsø and humpback whales in Tromsø appear each year.

Whales follow the food. Always.
When the herring arrive, the whales arrive. When the herring move, the whales move.

This natural cycle is what created Tromsø’s reputation as one of the world’s best winter whale watching destinations.

Do They Really Return Every Winter?

Orcas (Killer Whales) — Yes, with High Consistency

Orcas are extremely adaptable and have returned to northern Norway for decades.
They follow herring along the coast, shifting between:

• Tromsø fjords
• Skjervøy
• Lyngen
• Kvænangen
• And occasionally as far south as Vesterålen

Most winters we see large pods of orcas feeding, socializing, and traveling through the fjords.

Why so reliable?
Orcas hunt cooperatively and are very efficient. They’re excellent at tracking herring, even when the shoals move.

Humpback Whales — Also Yes, but in Varying Numbers

Humpbacks migrate from warm breeding grounds to northern Norway every winter to feed.

They’re usually present from:
Early November → Late January

However, the number of humpbacks changes year to year based on:

• Location of the herring
• Water temperature and currents
• Competition with other whale species
• Availability of plankton and other prey

Some winters are “humpback heavy,” others are “orca dominant,” but both species are typically observed.

Why Whales Sometimes Shift Away from Tromsø

It is important to understand that the whales are not “based” in Tromsø.
They are migratory and go wherever the food goes.

When the herring moved north toward Skjervøy (around 2016–2020), the whales followed.
When the herring shifted closer to Tromsø in later years, so did the whales.

This is why tours in northern Norway adjust their departure areas — to stay close to the whale activity and ensure ethical, respectful wildlife encounters.

When Are Your Best Chances of Seeing Orcas and Humpbacks?

Peak Season Window (Most Reliable):

15 November – 10 January

During this period, the fjords around Tromsø tend to host:

• Large orca pods (family groups)
• Numerous humpbacks feeding on herring
• Occasional fin whales and porpoises
• Incredible Arctic seabirds (sea eagles, guillemots, auks)

Shoulder Season (Possible but Less Predictable):

Late October & Late January

Whales may still be present, but sightings depend heavily on herring movement.

How Whale Watching Works During Polar Night

Tromsø enters Polar Night between late November and mid-January, meaning the sun doesn't rise.

But don’t worry — you can still see whales clearly because the Arctic “blue light” creates enough visibility for safe wildlife viewing.

This twilight creates magical conditions for:

• Orcas surfacing in purple and pink skies
• Humpbacks tail-slapping against icy mountains
• Snowy fjords glowing under Arctic daylight

It’s one of the biggest reasons Tromsø winter whale safaris have become world famous.

What Arctic Whale Tours Observes Each Winter

Arctic Whale Tours has monitored whale activity for several seasons.
What we consistently see:

Orcas are present almost every day of the season

Usually in multiple pods, feeding and socializing.

Humpbacks are present most days, in varying group sizes

Some winters there are hundreds; some winters dozens — but they are regular visitors.

Whale sightings in Tromsø are extremely reliable

Even with natural fluctuations, Tromsø remains one of the most dependable whale watching locations on earth.

Whale behavior changes as the season progresses

Early season: Active feeding
Mid-season: Large groups + stable herring
Late season: Whales begin to disperse

Why Tromsø Is Still One of the World’s Best Whale Destinations

Even as whale movement shifts slightly year to year, Tromsø remains exceptional because:

✔ Herring consistently return to northern Norway
✔ Orcas & humpbacks have reliable migratory patterns
✔ Fjords are close to shore → less travel time
✔ Ethical whale watching practices protect the animals
✔ Local expertise ensures safe, responsible encounters

For travellers looking for wildlife-focused education and a chance to see whales responsibly, Tromsø remains a top-tier Arctic destination.
