Northern Lights

What the aurora is, and why Canada is so good for it

The northern lights are what you see when charged particles streaming off the Sun hit Earth's upper atmosphere. Earth's magnetic field funnels them toward the poles, where they collide with oxygen and nitrogen 60 to 200 miles (100 to 320 km) up and make those gases glow. Oxygen gives the common green and the rarer deep red at the top of tall displays; nitrogen gives the pink and purple fringes you see along the bottom edge of a strong show.

The glow happens most often in a ring around the geomagnetic north pole called the auroral oval. Because the oval is centered near northern Greenland and Canada's Ellesmere Island, it tilts toward North America and passes right over a big band of northern Canada, including Yellowknife, Whitehorse and Churchill. In those towns you do not need a big solar storm. On an ordinary clear, dark night, there is a good chance of seeing something, and on a good night the whole sky moves.

Canada also has what most aurora countries lack: towns of real size right under the oval with regular flights, hotels, tour operators and roads, plus low light pollution, long winter nights and, in the Northwest Territories, a dry continental climate that gives more clear nights than coastal places like Norway or Iceland. Compared with Alaska, the experience is similar; the Canadian bases are often easier to reach from the Midwest and the East, and the exchange rate helps.

Is 2026–27 still a good year?

The Sun runs on an 11-year cycle, and NASA and NOAA announced in late 2024 that the current cycle had reached its maximum. Activity is now slowly easing, but the years just after a peak still bring frequent strong storms; some of the biggest displays of a cycle come during the decline. For a trip under the auroral oval, the cycle matters less than weather and darkness. Book for the right place and the right number of nights, and the Sun usually cooperates.

Where to go in Canada

When to go: season, moon and weather

The aurora happens year-round, but you can only see it when the sky is dark. North of 60°, summer nights never get dark, so the season runs from about late August, when real darkness returns, to mid-April. Within that window you are choosing between two very different trips.

Geomagnetic activity tends to run a little higher in the weeks around the September and March equinoxes, which is why so many people book those months. If you want the aurora plus a classic snowy northern trip, February and March are the sweet spot. If you hate cold, September is the gentlest introduction.

The moon

A full moon brightens the sky and washes out faint aurora, though a strong display still shows. If your dates are flexible, aim for the week on either side of a new moon. A partial moon is not a disaster; it lights the snow and the landscape, which makes better photos.

Clouds matter more than anything

The single biggest reason people miss the aurora is cloud cover. Plan at least three nights, ideally four or five, so that one or two overcast nights don't sink the trip. Check the cloud forecast every afternoon, and if you are on your own with a car, be ready to drive to clear patches. Tour operators in Whitehorse and Yellowknife often do this for you.

Aurora forecasts and apps

Aurora forecasting is a real science, but it works best a few hours out. A 27-day or even 3-day outlook tells you little; a 30-minute forecast tells you a lot. Use these:

• NOAA Space Weather Prediction Center (swpc.noaa.gov): the US government's space weather service. Its aurora dashboard shows a 30-minute forecast of the oval and the 3-day Kp outlook, and it covers Canada well.
• Canadian Space Weather Forecast Centre (spaceweather.gc.ca): Natural Resources Canada's forecasts, with regional outlooks for the auroral zone, subauroral zone and southern Canada.
• AuroraWatch (aurorawatch.ca): a University of Alberta project that monitors geomagnetic activity in real time over the Edmonton area and sends free email alerts when it jumps. Most useful in Alberta and the western provinces.
• Phone apps such as My Aurora Forecast and SpaceWeatherLive pull together Kp, solar wind data and push alerts. They're handy for alerts; trust the maps above for decisions.
• Cloud forecasts from Environment Canada's weather site and its satellite imagery, or apps that show cloud layers by hour.

Reading the numbers

The Kp index runs from 0 to 9 and measures global geomagnetic activity over three-hour blocks. Under the oval in Yellowknife or Churchill, Kp 1 to 3 is often enough for a good show. Whitehorse does well from about Kp 2 to 3. Jasper and the Rockies usually need Kp 5 or more, and southern Canada needs a major storm at Kp 6 to 7 or above.

For short-term hunting, watch the solar wind's "Bz" value on NOAA's real-time charts. When Bz turns strongly negative (south) and stays there, activity tends to pick up within the hour.

Tours, camps and lodges

You can see the aurora on your own, but most first-timers take tours for good reason: operators have dark sites away from town, heated shelters, hot drinks, transport on icy roads and guides who know when to step outside.

Viewing camps: the Aurora Village model

Yellowknife's signature experience is the viewing camp. The best known is Aurora Village, on the Ingraham Trail about 30 minutes from downtown, where you wait between bursts in heated teepees. Buses pick up at the hotels in the evening, and in the 2026 fall season viewing ran from about 10 or 11 pm to 2:30 or 3 am. Guides speak several languages because the camp is popular with visitors from Japan, Korea and China. Packages combine nightly viewings with hotels, airport transfers and a five-piece rental clothing set; a package listing for 2026 priced extra viewing nights at C$110 (about $79) per person including tax. By day, Aurora Village and other operators run dog sledding, snowshoeing and city tours.

Other Yellowknife operators run smaller camps, cabins and "chase" tours that drive to wherever the sky is clear. Look for small groups, a heated shelter and a guide who will take photos for you.

Whitehorse

Whitehorse operators drive groups to heated cabins or wall tents in the hills outside town, typically from late evening to about 2 am. Package tours are common: one 2026 listing priced three days and two nights at C$675 (about $480) per person double, four days at C$860 (about $615) and five days at C$1,050 (about $750), plus 5% GST, with hotel, airport transfers, a city tour, nightly viewing and hot drinks. Rental clothing in that package was another C$160 to C$205 (about $115–145) for two to four nights.

Churchill

Churchill's aurora trips are mostly all-inclusive packages from Winnipeg, with flights, lodging, meals, viewing from heated buildings or yurts on the edge of town, and daytime dog sledding and cultural programs. Frontiers North, one of the main operators, now includes a parka, snow pants and heavy boots on its winter tours. The Churchill Northern Studies Centre, a research station outside town, runs aurora-focused learning programs. Expect multi-thousand-dollar trip prices; book by late fall for February and March.

Wilderness lodges

For a splurge, fly-in lodges outside Yellowknife and Whitehorse put you in total darkness with no one else around, with meals and activities included. They usually require a minimum stay and a small-plane or ski-plane transfer.

What it costs

Northern Canada is expensive, mainly because of flights and the fact that everything else arrives by truck or plane. All prices are before tax unless noted; the territories charge only the 5% GST, with no provincial sales tax, and Manitoba adds its own. Tipping works much as in the US: 15% to 20% for guides and drivers. See money.

Dressing for -40°F

At -40, Fahrenheit and Celsius meet, and so does almost every American's sense of what "cold" means. Standing still outside at 1 am in Yellowknife or Churchill in January is colder than skiing at 5°F in Colorado, because you're not moving. Most Americans' city winter coats will not do the job.

• Base layer: merino wool or synthetic long underwear, top and bottom. No cotton anywhere; it holds sweat and freezes.
• Mid layer: a fleece or light down jacket, plus fleece pants.
• Outer layer: a long, hooded expedition-weight down or synthetic parka and insulated snow pants or bibs. This is what rental sets cover.
• Feet: boots rated to -40 with removable felt liners, worn over one pair of thick wool socks. Leave room for your toes to move; tight boots freeze feet.
• Hands: thin liner gloves for working a phone or camera, under heavy mittens. Mittens are much warmer than gloves.
• Head and face: a warm hat (Canadians call it a toque), a neck gaiter or balaclava, and goggles in wind.
• Extras: chemical hand and toe warmers, a thermos of hot drink, snacks for energy, and a spare phone battery in an inside pocket.

At a wind chill of -40, exposed skin can freeze in under 10 minutes. Watch your companions for white patches on cheeks and noses, and go inside to warm up at the first sign. Renting is usually smarter than buying for one trip; if you do buy, Yellowknife and Whitehorse outdoor stores sell gear designed for local conditions. More on cold-weather clothing on the winter and packing pages, and on frostbite on the health page.

Photographing the aurora with a phone or camera

Cameras capture aurora better than your eyes do. Faint displays that look gray-white to you show up bright green in a long exposure, so even a weak night can produce good photos.

With a phone

1. Use night mode (Night mode on iPhone, Night Sight or Astrophotography on Pixel, Night or Pro mode on Samsung). Turn the flash off.
2. Steady the phone. A small tripod with a phone clamp is best; a snowbank, a car roof or a beanbag works. On a tripod, newer iPhones allow night exposures up to 30 seconds.
3. Use the self-timer so your tap doesn't shake the shot.
4. In Pro mode, set focus to infinity, ISO around 1600 to 3200, and the shutter to 3 to 10 seconds; shorter if the aurora is moving fast.
5. Keep the phone in an inside pocket between shots. Cold drains batteries in minutes, and a phone can shut itself off in deep cold even with charge left.

With a camera

• Lens: a wide-angle lens, 14 to 24 mm on full frame, at its widest aperture (f/2.8 or faster is ideal).
• Settings to start: manual mode, ISO 1600 to 3200, 5 to 15 seconds, white balance around 3,500 to 4,000 K, RAW files. Use 2 to 5 seconds for fast, bright displays so the curtains stay sharp.
• Focus: manual focus on a bright star or distant light using magnified live view, then tape the focus ring.
• Stability: a sturdy tripod, image stabilization off, a remote or 2-second timer.
• Cold and condensation: carry two or three spare batteries in an inside pocket. Before going indoors, put the camera in a sealed plastic bag so condensation forms on the outside of the bag and stays out of the lens.
• Composition: include a foreground: a teepee, a frozen lake, spruce trees, a person standing still. Headlamps on red mode only, and never point any light at someone else's camera.

Sample trips: 3 to 5 nights

Yellowknife in winter, 4 nights (February or March)

6. Day 6

   Back south

   Fly to Winnipeg and connect home.

Getting there from the US

There are no nonstop flights from the US to Yellowknife, Whitehorse or Churchill. The usual routing is a US city to Calgary, Edmonton or Vancouver, then a domestic flight of 2 to 2.5 hours. Air Canada, WestJet and Canadian North all fly Edmonton to Yellowknife daily, and Air North, Yukon's airline, runs a seasonal Vancouver–Yellowknife route that builds to five or six flights a week from January to late March 2027. From December 3, 2026, Air North also links Whitehorse, Yellowknife and Edmonton twice a week, which makes a two-city aurora trip much easier. Churchill is a flight from Winnipeg, or VIA Rail's train from Winnipeg, which takes about two days each way. See flights and getting around.

Driving is possible but serious: Edmonton to Yellowknife is about 930 miles (1,500 km) over two long days, and the Alaska Highway to Whitehorse is longer. In winter you need proper winter tires, a block heater, an emergency kit and a plan for long stretches with no cell signal or services. Read driving in Canada before you try.

• US passport book for flights; a passport card or enhanced driver's license works only by land. See entry requirements.
• Travel insurance with medical evacuation; care in the North is billed at non-resident rates and medevac flights are very expensive. See health.
• A phone plan that works in the territories; some US carriers' Canada coverage is thin north of 60. See staying connected.
• Book flights and the first nights of tours together, and leave a buffer day in winter, when weather delays northern flights.

What goes wrong

• Too few nights. Two nights is a gamble. Three is the minimum, and four or five give you real odds.
• Ignoring cloud. A high Kp forecast means nothing under overcast. Watch cloud forecasts as closely as aurora forecasts.
• Underdressing. Cold cuts more nights short than clouds do. Rent the full set if you are unsure.
• Dead batteries. Phones and cameras die fast. Carry spares warm, close to your body.
• Light pollution. Town lights and headlights ruin night vision. Give your eyes 15 to 20 minutes in the dark, and keep screens dim.
• Wildlife and roads. When self-driving, watch for moose, bison and caribou on dark roads, and never stop in a traffic lane. See safety.
