Visiting the Northwest Passage: Key factors

  • Expedition cruises only operate in August and September, once the narrow channels become ice free
  • August is the peak month for wildlife activity; by September wildlife is on the move again
  • September trips benefit from better chances of experiencing the Northern Lights
  • Average temperatures during this brief window are -5°C to +8°C (23°F to 26°F)
  • Due to increased melting of Arctic ice, making a full transit of the Northwest Passage is now all but guaranteed.

Whether it’s for the wildlife, Northern Lights or to visit Inuit communities that you’re heading north, it’s well worth paying attention to the monthly nuances to get the most from your trip.

When is the best time to go?

August

The excitement of August is that the receding ice allows the arrival of a small number of expedition ships, which provide the best means to explore the Northwest Passage on a cruise

Days are still long - helping to maximise wildlife sightings - and temperatures comparatively warm, however the weather can change rapidly and it can snow anytime.

Opportunistic polar bears by August – who have been following the migrating narwhal and beluga - can be found around Somerset and Prince of Wales Islands. Plus, remaining pockets of ice can assist bear sightings.

September

Shorter days, slightly cooler weather and higher chances of snow mark a step change in the seasons and the onset of autumn.

However, as the ice continues to melt through September it becomes easier to get to ice strewn locations, which were inaccessible earlier in the season. Plus, the longer nights increase the chances of seeing the Northern Lights.

Wildlife is still very much in the area, even though the majority of birds have now migrated south. September can provide excellent sightings – for example, five polar bears, 25 belugas and 12 feeding bowheads were recently sighted all on a single day.

Preparing for the weather

While these are the most benign months of the year weather-wise, it’s well worth being prepared with a range of clothing so you don’t get caught off guard. This is the High Arctic after all.

Temperatures in the Northwest Passage during cruising season generally range from -5°C to 8°C (23°F to 46°F), plus a high wind-chill factor. 

Bearing this in mind, you should prepare suitable clothing. It's important to have waterproof trousers and insulated layers for zodiac trips. Rubber boots are usually loaned to you by the ship.

Northwest Passage: FAQs

  • What is the Northwest Passage?

    The Northwest Passage is a sea route connecting the North Atlantic and Pacific Oceans via waterways through the islands of the Canadian Arctic archipelago.

    For centuries explorers sought the existence of a navigable passage, however it wasn’t until 1903–1906 when the Norwegian Roald Amundsen made the first successful transit.

  • How do I get to the Northwest Passage?

    Anchorage, Calgary, Toronto, Ottawa are the main international gateways for onward scheduled and charter flights to the start and end points for Northwest Passage cruises further north.

    These start and end points are typically Nome in Alaksa; Cambridge Bay, Resolute and Kugluktuk (Coppermine) in the Canadian Arctic; or Kangerlussuaq and Nuuk in West Greenland.

  • What’s so interesting about the Northwest Passage?

    The search for the fabled Northwest Passage stretched across four centuries and is a fascinating story of failure, disaster and tragedy, but also of great heroism and endurance which continues to resonate and be of great interest.

    Recent changes in Arctic climate and the viability of an ice free Northwest Passage for commercial shipping has further peaked interest in this incredibly rich historical region.

  • Is it common to see polar bears in the Northwest Passage?

    There are three main variables - alongside luck, which none of us can control - to bare in mind when it comes to giving yourself the best chance of seeing polar bears:

    1. Length of trip: Put simply, the longer your trip the greater your chances of wildlife encounters

    2. The Itinerary: While polar bears are very nomad, there are well-known polar bear ‘hotspots’ (e.g. Coningham Bay, Lancaster Sound, Croker Bay and Bellot Strait)

    3. Calibre and size of the expedition team: You want a big and very experienced team, as that means there will always be lots of sets of eyes on watch for wildlife. And, secondly, from experience, they’ll also know where to look, which will further improve your chance of successful sightings

  • Is it possible to make a full transit of the Northwest Passage?

    With the sadly increasing summer temperatures in the Arctic and resultant melting of the ice, successfully transiting the Northwest Passage is now all but guaranteed, in a way that it wasn’t 20 years ago.

  • Should I choose a smaller or larger expedition ship?

    This is a key question, and in the Northwest Passage there are several ways to think about it:

    Firstly, you should consider what's most important to you, as there are trade-offs. A smaller ship typically lends itself to a more intimate experience, where you’ll get to know a greater proportion of your fellow passengers, and getting on and off the ship will be speedier.

    However, the anonymity of a larger ship, alongside normally more on-ship amenities and a wider choice of dining locations (particularly on a longer voyage) can be attractive. There’s no right or wrong answer, it's simply down to personal choice.

    The other way to look at it – given the relatively limited number of Northwest Passage itineraries and ships – is to focus on choosing the right trip first, as depending on which you choose, there may only be one or two ships from which to choose.
