If you are planning a winter trip to Northern Norway, one question usually appears very quickly:

When is the best time for whale watching in Tromsø?

The short answer is that the main whale-watching season runs from November through January.

But there is an important second part to that answer:

There is no single month that can honestly be guaranteed as “the best” for whales.

Orcas and humpback whales come to Northern Norway because of food, particularly the enormous concentrations of Norwegian spring-spawning herring that gather in northern waters during winter.

The whales do not follow our tourism calendar.

They follow the food.

That means November, December and January can all produce remarkable encounters, while the exact location and concentration of whales can change from one season to another.

What changes much more predictably between these months is the wider Arctic experience:

• The amount of daylight
• The Polar Night
• The colour of the winter sky
• Snow and winter conditions
• Photography opportunities
• The other activities you can combine with whale watching

So instead of asking only:

“Which month has the most whales?”

it is often more useful to ask:

“Which month gives me the kind of Arctic trip I want?”

Let’s compare November, December and January.

When Is Whale-Watching Season in Tromsø?

The main whale-watching season in the Tromsø region is November to January.

Visit Tromsø's official whale-watching guide also identifies November through January as the main season and explains that the whales follow the herring into the fjords of Northern Norway.

Arctic Whale Tours operates its full-day winter safari from Tromsø during this period aboard MS Alba.

The current safari departs at 08:30 and normally lasts approximately 8 hours, plus or minus around one hour, depending on weather, sea conditions and where the whales are located.

You can check current operational details and availability on the Arctic Whale Tours Winter Whale Safari page.

The main species we search for are:

• Orcas
• Humpback whales

Other cetaceans, including fin whales, dolphins or harbour porpoises, may occasionally be encountered.

But no particular species can be guaranteed.

Why Are There Orcas and Humpback Whales in Northern Norway in Winter?

To understand when to visit Tromsø, it helps to understand why the whales are here at all.

The winter whale season is closely connected to Norwegian spring-spawning herring.

Huge numbers of these fish gather in northern Norwegian waters during winter.

Where large concentrations of herring appear, predators can follow.

Among them are:

orcas and humpback whales.

Orcas are highly adaptable hunters and can work together to concentrate herring into dense groups.

Humpback whales can also take advantage of the same seasonal feeding opportunity.

This relationship between whales and herring is the foundation of the winter whale-watching season.

But there is one very important complication:

The herring do not always winter in exactly the same place.

Norway's Institute of Marine Research has documented major changes in where Norwegian spring-spawning herring spend the winter.

Its 2025 wintering-herring survey found significant concentrations in Altafjorden, Kvænangen and Sørøysundet.

But in January 2026, the Institute also reported that much of the herring appeared to have wintered somewhere else that season, possibly farther offshore.

The researchers specifically described the herring's wintering behaviour as unpredictable.

That matters enormously for whale watching.

When the herring distribution changes, the whales can change their movements too.

This is why we do not recommend choosing a specific week because somebody claims it always has more orcas.

Nature is much more dynamic than that.

Is November a Good Time for Whale Watching in Tromsø?

Yes.

November can be an excellent choice, particularly if you want the winter whale season without spending your entire visit in the Polar Night.

At the beginning of November, Tromsø still has a conventional sunrise and sunset.

As the month progresses, the days shorten rapidly.

By late November, the sun no longer rises above the horizon.

According to Visit Tromsø's winter guide, the Polar Night lasts approximately from 27 November to 15 January.

That makes November a fascinating transition month.

Why choose November?

November may suit you if:

• You prefer more natural daylight
• Photography is particularly important to you
• You want to experience the beginning of the Arctic winter
• You want whale watching and Northern Lights opportunities during the same holiday
• You are unsure whether you want to experience the deepest part of the Polar Night

Early November and late November can feel surprisingly different.

Early November

You still have sunrise and sunset.

This gives photographers more available light and gives first-time Arctic visitors something closer to a familiar day-night rhythm.

Late November

The Polar Night begins.

The sun remains below the horizon, but daylight does not disappear completely.

Instead, the middle of the day develops into a period of Arctic twilight.

Does November Have More Whales?

We would not make that claim.

One winter may begin with strong whale activity in accessible areas.

Another season may develop differently.

The whales respond primarily to prey distribution, not the name of the month.

So choose November because you want the November experience, not because somebody promises more whales.

Is December a Good Time for Whale Watching in Tromsø?

Absolutely.

December offers perhaps the most distinctive Arctic winter atmosphere of the entire season.

Tromsø is in the heart of the Polar Night.

The sun does not rise above the horizon.

However, that does not mean that you spend your whale safari in complete darkness.

This is one of the most common misunderstandings about winter travel in Tromsø.

As Visit Tromsø explains in its guide to the seasons, the sky still brightens around the middle of the day.

Instead of normal daylight, you experience a blend of dawn and dusk.

Depending on weather conditions, the landscape can take on shades of:

• Blue
• Pink
• Purple
• Gold

Snow-covered mountains combined with this low winter light can create an extraordinary setting for whale watching.

Why choose December?

December may suit you if:

• You specifically want the Polar Night experience
• You love dramatic Arctic light
• Snowy winter scenery is a major part of your trip
• You want to combine whales with Tromsø's Christmas atmosphere
• You want plenty of darkness for evening Northern Lights activities

For many travellers, December feels like the most distinctly Arctic month.

Is December Too Dark for Whale Watching?

No.

The sun does not rise, but there are still several hours of twilight around the middle of the day.

Visit Tromsø's official whale-watching information specifically points out that the Polar Night does not mean complete daytime darkness and highlights the coloured twilight as part of the whale-watching experience.

The amount and quality of light still depend heavily on:

• Cloud cover
• Weather
• Exact date
• Your location
• Snow conditions

Photography can be more challenging than in brighter November conditions, but the resulting atmosphere can also be exceptional.

Is January a Good Time for Whale Watching in Tromsø?

Yes, during the active part of the whale-watching season.

January gives you another version of Arctic winter.

At the beginning of the month, Tromsø remains in the Polar Night.

Then the days gradually become brighter.

The sun rises above the astronomical horizon again around mid-January, although the surrounding mountains mean direct sunlight may not immediately reach every part of Tromsø.

Visit Tromsø notes that daylight begins returning from mid-January, making the month a noticeable transition toward brighter winter days.

Why choose January?

January may suit you if:

• You want deep winter scenery
• You like the idea of the light gradually returning
• You want whale watching and Northern Lights in the same holiday
• You prefer travelling after the Christmas period
• You want to experience the transition out of the Polar Night

But January also requires a little more attention to timing.

The whale-watching season does not continue indefinitely through winter.

As herring begin changing their distribution and eventually moving toward spawning areas, whale activity can also change.

Research tracking Norwegian killer whales has shown that their movements are closely associated with migratory herring, reinforcing why the later part of the season should never be treated as permanently fixed.

For this reason, always check the current AWT booking calendar before planning a late-January trip around whale watching.

November vs December vs January

Here is the simplest way to compare them:

The most important line is the last one.

No month guarantees whales.

Which Month Has the Most Whales?

We do not believe it is responsible to give a simple answer.

It would certainly be convenient to say:

“December is the best month.”

or:

“Come in November because there are more orcas.”

But without robust long-term local sighting data demonstrating a consistent month-by-month pattern, those statements create false confidence.

The winter ecosystem is dynamic.

The Norwegian Institute of Marine Research's recent observations of shifting herring wintering areas are a good example of why.

The whales respond to:

• Herring distribution
• Ocean conditions
• Prey availability
• Their own movements
• Weather
• Accessible feeding areas

So the best month should usually be chosen based on the type of Arctic trip you want, rather than a promise of more whales.

Which Month Should You Choose?

Choose November if you want more daylight

November is particularly appealing for:

• First-time winter visitors
• Families
• Photographers
• Travellers who prefer more conventional daylight
• Guests who want both whales and Northern Lights without spending the whole trip in the Polar Night

Early November provides the greatest difference.

Choose December if you want the Polar Night

December offers:

• Blue Arctic twilight
• Snow-covered landscapes
• Christmas atmosphere
• Long dark evenings
• Excellent opportunities to combine daytime whale watching with evening Northern Lights activities

Choose December for atmosphere rather than because it is supposedly the “best whale month.”

Choose January if you want returning light

January offers:

• Deep winter
• Gradually increasing twilight
• The end of the Polar Night
• Northern Lights
• Winter activities
• Whale watching during the later portion of the season

Just make sure the safari is still operating on your travel dates.

Where Are the Whales?

This is another important point.

Tromsø is the departure point.

It does not mean the whales are waiting immediately outside Tromsø Harbour.

The winter herring concentrations have shifted over time.

Visit Tromsø explains that whales have followed the herring farther north in recent years, while current research from the Institute of Marine Research continues to document substantial herring concentrations in northern fjord systems.

This is why Arctic Whale Tours operates a full-day safari.

Depending on current conditions, considerable time may be spent travelling through the fjords and coastal waters before reaching the area where whales are being found.

The journey itself is part of the experience.

What Is the Tromsø Whale Safari Like?

Arctic Whale Tours operates aboard MS Alba, a 26-metre Norwegian catamaran.

The current full-day safari departs from the Vervet harbour area in Tromsø.

Onboard facilities include:

• Heated indoor lounge
• Panoramic windows
• Outdoor observation decks
• Toilets
• Hydrophone system

The current safari duration is approximately 8 hours ±1 hour, depending on conditions and whale location.

Full practical details are available on the current Arctic Whale Tours winter safari page.

For a complete step-by-step explanation of the day itself, read What to Expect on a Winter Whale Safari in Tromsø.

Can You See Orcas Every Day?

No.

Orcas are one of the main species associated with Northern Norway's winter herring concentrations, but they remain wild animals.

On one departure, you may encounter several groups.

On another day, the animals may be:

• Farther away
• Spread across a larger area
• Travelling
• Difficult to locate
• Outside areas that can reasonably be reached that day

No responsible wildlife operator should promise that you will see an orca on a particular departure.

What About Humpback Whales?

Humpback whales are another important part of the winter feeding ecosystem.

They can exploit the same rich herring concentrations and may occur in the same general feeding areas as orcas.

Possible behaviour can include:

• Travelling
• Feeding
• Diving
• Tail fluking
• Several whales using the same feeding area

More dramatic behaviours such as breaching can happen, but they should never be presented as something guests should expect on every trip.

Can You See Other Whale Species?

Other cetaceans may also occur.

Depending on the season and natural conditions, possible additional encounters can include:

• Fin whales
• Dolphins
• Harbour porpoises

These should be considered additional possibilities.

The primary winter focus remains:

orcas and humpback whales.

What Is Whale Watching Like During the Polar Night?

Very different from summer whale watching.

And that is part of the appeal.

During the Polar Night, the sun remains below the horizon, but the middle of the day still develops into a period of twilight.

The winter landscape can appear:

• Deep blue
• Pink
• Purple
• Silver
• Gold

A whale surfacing against snow-covered mountains in this light creates an experience that is completely different from whale watching beneath the midnight sun.

The Polar Night is therefore not something travellers necessarily need to avoid.

For many guests, it becomes one of the most memorable parts of the trip.

Which Month Is Best for Photography?

It depends on the type of images you want.

November

Potential advantage:

More available light, especially early in the month.

That can make photographing fast-moving orcas technically easier.

December

Potential advantage:

The strongest Polar Night atmosphere.

The challenge is lower light, but the colour of the sky can be extraordinary.

January

Potential advantage:

Increasing light combined with deep-winter scenery.

There is no universally best photography month.

A bright overcast December day could provide easier conditions than a stormy November morning.

Weather still matters enormously.

Which Month Is Best for Families?

There is no fixed answer.

November may appeal to families who prefer more daylight.

But the more important question is whether the child is comfortable with the nature of the experience.

The Tromsø safari is a full-day trip.

Parents should consider:

• The approximately eight-hour duration
• Cold weather
• Vessel movement
• Possible seasickness
• Long sailing periods
• Waiting while searching for wildlife

MS Alba has heated indoor seating and toilets, which gives families somewhere to take breaks during the journey.

For a more detailed assessment, read our Family Guide to Winter Whale Watching in Tromsø.

Can You See the Northern Lights During the Same Trip?

You can combine whale watching and Northern Lights on the same holiday very easily.

But they should be treated as separate experiences.

The whale safari operates during the daytime and twilight period.

Northern Lights viewing generally takes place during the evening or night.

According to Visit Tromsø's Northern Lights guide, the main aurora-viewing period extends from late summer into early spring when the sky becomes dark enough to see the phenomenon.

So you could theoretically do:

Whale safari → dinner → Northern Lights excursion

on the same day.

However, remember that the whale safari itself is a long day.

Many travellers prefer to keep their aurora excursion for a separate evening.

What Should You Wear?

Whichever month you choose, dress for Arctic winter.

Conditions at sea can feel considerably colder than conditions in Tromsø city because of wind and exposure.

Dress in layers.

A useful setup includes:

• Wool or thermal base layer
• Warm fleece or wool mid-layer
• Insulated winter jacket
• Windproof and waterproof outer layer
• Warm trousers
• Wool socks
• Winter footwear
• Hat
• Gloves
• Neck warmer

It is much easier to remove a layer than to spend several hours wishing you had brought one.

What About Seasickness?

The safari lasts most of the day and travels through coastal and fjord waters.

Conditions vary.

Some departures are relatively calm.

Others involve more movement.

If you know that you are prone to motion sickness, consider suitable preventative medication before departure, following instructions or advice from a pharmacy or medical professional.

Bring your own medication.

Do not assume a catamaran means seasickness is impossible.

What If the Weather Is Bad?

Winter weather in Northern Norway can change quickly.

Wind, waves and other sea conditions may affect:

• The route
• The amount of time spent searching
• Passenger comfort
• Whether a safari can operate safely at all

The captain's safety decision comes first.

If whale watching is one of the main reasons you are travelling to Tromsø, avoid building an itinerary where everything depends on one single day if you have the flexibility to stay longer.

How Long Should You Stay in Tromsø?

For most winter travellers, three or four nights or more makes planning much easier.

That gives you time for:

• Whale watching
• Northern Lights
• Weather flexibility
• Dog sledding
• Reindeer experiences
• Exploring Tromsø
• Rest between longer excursions

Both whales and the Northern Lights are natural phenomena.

Giving yourself several opportunities reduces the pressure on any single day.

Is There a Best Week for Whale Watching?

We would not recommend one.

Claims such as:

“The second week of December is the best week for orcas.”

sound precise.

But unless they are based on meaningful long-term data, they are not reliable enough to plan an international holiday around.

Whale distribution can change over very short periods.

The better strategy is:

1. Travel during the active winter whale season.
2. Choose the month based on the wider Arctic experience you want.
3. Allow some itinerary flexibility where possible.

Should You Book Early?

Yes, particularly if:

• Your dates are fixed
• You are travelling around Christmas or New Year
• You are a family
• You have a larger group
• Whale watching is one of the most important activities of your trip

Booking early secures your place on the safari.

It does not guarantee what wildlife will appear.

November, December or January: Our Recommendation

There is no single best month for everyone.

Choose November if:

You want more daylight, especially earlier in the month.

Choose December if:

You want the deepest Polar Night atmosphere and classic Arctic winter experience.

Choose January if:

You want winter whale watching with gradually returning light, while travelling during the active part of the season.

For the whales themselves:

Do not choose your month because somebody promises more orcas or humpbacks.

The most important natural factor is the herring.

And, as the Institute of Marine Research continues to document, the herring's winter distribution can change considerably.

That unpredictability is not a weakness of whale watching.

It is what makes watching genuinely wild animals fundamentally different from visiting an attraction with a fixed schedule.

Plan Your Tromsø Whale Safari

If whale watching is an important part of your Northern Norway trip, remember three things:

Travel during the active November–January season.

Allow some flexibility in your itinerary.

Choose your month based on the Arctic experience you want rather than a promise of more whales.

November gives you more daylight.

December gives you the heart of the Polar Night.

January brings the gradual return of light.

Throughout the season, the objective remains the same:

Leave Tromsø aboard MS Alba.

Travel north through the Arctic fjords.

Search the winter feeding areas.

Watch the horizon.

And see what the Northern Norwegian ecosystem reveals that day.

Frequently Asked Questions

What is the best month for whale watching in Tromsø?

There is no single month that guarantees better whale sightings. The main season runs from November through January. November offers more daylight, December provides the deepest Polar Night atmosphere, and January brings gradually returning light.

When can you see orcas in Tromsø?

Orcas are one of the main species associated with Northern Norway's winter whale season from November to January. Their exact location and daily presence depend largely on prey movements and cannot be guaranteed.

Can you see humpback whales in Tromsø in December?

Yes, humpback whales can occur during December and throughout the winter whale season. However, sightings depend on natural whale and herring movements.

Is December too dark for whale watching in Tromsø?

No. Although the sun does not rise during the Polar Night, there are still several hours of twilight around midday. It is not completely dark throughout the daytime.

Is November or December better for whale watching?

Neither month can reliably be described as better for the whales themselves. November provides more daylight, while December offers the full Polar Night experience.

Can you see whales in Tromsø in February?

The main whale-watching season is November through January. Herring and whale distribution change as winter progresses, so visitors should not assume that the same organised whale-watching opportunities continue into February.

Are whales guaranteed in Tromsø?

No. Orcas, humpback whales and other cetaceans are wild animals, so no particular species or sighting can be guaranteed.

Can I see the Northern Lights during the whale safari?

The whale safari takes place during the daytime and twilight period. Northern Lights are better treated as a separate evening or nighttime activity.
