The Northern Lights in Norway

Updated November 2026

A guide to seeing the aurora in Norway

The Northern Lights are seen most often in a broad ring around the far north of the planet, and the coast of northern Norway runs straight underneath it. From the Arctic Circle to the North Cape, a clear winter night and an active Sun can turn the whole sky green, sometimes for minutes, sometimes for hours.

The question we hear most is a simple one: when should I go, and how likely am I to see them? This guide answers it as honestly as we can, with the science in plain language, the best months, hours and places, flights from the UK, and the practical things that help on the night. If you already know you want to go, see all our Northern Lights voyages.

The Science

What causes the Northern Lights?

The Northern Lights are caused by charged particles from the Sun colliding with gases high in Earth's atmosphere. The Sun sends out a constant stream of particles, the solar wind, and occasionally much larger bursts called coronal mass ejections. Earth's magnetic field deflects most of this, but some of the energy is stored in the magnetosphere and released down the field lines towards the poles. When the particles strike oxygen and nitrogen around 100 km or more above the ground, the gases glow.

Because the field lines converge near the magnetic poles, the energy is funnelled into two rings, the auroral ovals. In the north the result is the aurora borealis; in the south, the same process creates the aurora australis, or Southern Lights. A coronal mass ejection aimed at Earth can supercharge the whole system, and the US Space Weather Prediction Center notes that the fastest can reach Earth in as little as 15 to 18 hours. Norway's Arctic coast sits so close to the northern oval that the lights often appear directly overhead rather than as a glow on the horizon.

In the winter of 1882 to 1883 the Danish researcher Sophus Tromholt, observing from Kautokeino in Finnmark, put the average height of the aurora at 113 km. That is far above any weather, so cloud never affects the lights themselves, only your view of them.

Why are the Northern Lights green, red or purple?

• Green is the most common colour, from oxygen at roughly 100 to 300 km, most of it in the lower part of that band. Our eyes are also most sensitive to green.
• Red also comes from oxygen, but higher, at roughly 300 to 400 km. It shows at the top of tall curtains or during strong storms.
• Blue and purple come mainly from nitrogen. When particles reach below about 100 km, nitrogen gives the lower edge of a curtain a pink or purplish fringe.

Cameras pick up colour in the dark far better than the eye, so a silvery arc on deck can come out bright green on your phone. The colour is real; our eyes simply struggle to see it in low light.

What is the Kp index?

The Kp index, quoted in every aurora app, is a scale from 0 to 9 measuring how disturbed Earth's magnetic field is. The higher the number, the further the oval spreads towards lower latitudes, and Kp 9 is the kind of extreme storm that brings the lights over southern England. Northern Norway needs nothing like that. With the oval more or less overhead, displays happen even at low Kp, so a modest forecast is no reason to stay indoors on a clear night.

Names and Folklore

Where does the name aurora borealis come from?

Aurora borealis joins Aurora, the Roman goddess of the dawn, with Boreas, the Greek name for the north wind. The term is often credited to Galileo Galilei in about 1619, though Pierre Gassendi was also using it by 1621. In Norwegian the lights are simply nordlys, the northern light.

One of the earliest written accounts from Norway is the King's Mirror, or Konungs skuggsjá, an Old Norse text from around the middle of the thirteenth century. It describes the lights seen from Greenland and weighs up three explanations: fire circling the outer ocean, sunlight escaping round the edge of the world, and frost and glaciers giving out light. The author found the last quite plausible, though he admitted he could not be sure.

For the Sámi, the indigenous people of the far north, the lights called for caution and respect. Many traditions linked them to the souls of the dead, and it was thought unwise to wave, whistle or sing beneath them in case they came down for you. Popular retellings of Norse belief, meanwhile, connect the lights with the shining armour of the Valkyries, or with Bifröst, the bridge between earth and heaven. These are better enjoyed as folklore and later interpretation than read as firm history.

Timing

When is the best time to see the Northern Lights in Norway?

The best time to see the Northern Lights in Norway is between late September and late March, on a clear, dark night, usually between about 6pm and 1am. The aurora happens all year, but from April to August the far north is too light to see it, and in high summer the Midnight Sun means there is no darkness at all. On any given night, what matters is solar activity, darkness and cloud.

Which month is best?

There is no single best month, and anyone who promises one is guessing. Each part of the season has its own character on the coast north of the Arctic Circle.

A general guide only. Weather and solar activity vary from night to night, and the aurora can never be guaranteed in any month.

What time of night are the Northern Lights most active?

Displays can begin as soon as it is properly dark, which in midwinter can be mid afternoon. The most likely hours are roughly 6pm to 1am, and the US Space Weather Prediction Center says the best aurora is usually within an hour or two of midnight. Plenty of strong displays arrive earlier, though, so keep an eye on the sky from dinner onwards. Activity comes in waves, with a quiet arc suddenly brightening into moving curtains before calming again.

The polar night

Above the Arctic Circle there is a period around midwinter when the sun does not rise at all. In Tromsø it lasts from about 27 November to 15 January. It is not pitch black for weeks, as people imagine: around midday there are a few hours of deep blue and pink twilight, and the long darkness either side gives the aurora many more hours in which to appear.

Are the equinoxes really better?

There is good science behind the idea that the months around the equinoxes tend to be more geomagnetically active. Known as the Russell McPherron effect, it comes from the way Earth's magnetic field lines up with the field carried by the solar wind at that time of year, letting more energy in. Going by British Geological Survey data, a sizeable magnetic storm happens, on average, on nearly twice as many days in March as in June or July. It is a tendency, not a rule.

The solar cycle

The Sun runs through a cycle of roughly eleven years. In October 2024 NASA and NOAA announced that it had reached the solar maximum period of Solar Cycle 25. Maximum is a phase rather than a single date, and strong storms can still come in the years of decline that follow. Nobody can forecast individual displays this far ahead, but even in quiet years northern Norway sits close enough to the oval for the lights to be a regular sight.

The Moon and the weather

A full moon will not hide a good display but does wash out fainter ones, so the weeks around the new moon have the edge. Cloud matters more, and the coast has changeable weather, which is one of the best arguments for travelling by ship.

Where to Look

Where is the best place to see the Northern Lights in Norway?

The best places to see the Northern Lights in Norway are north of the Arctic Circle, from Lofoten and Vesterålen through Tromsø and Alta to the North Cape and Kirkenes. All lie under or close to the auroral oval. Further south, in Bergen, Oslo or the fjords, the lights are only seen during stronger storms. The Hurtigruten route crosses the Arctic Circle at about 66 degrees 33 minutes north and then spends several days in this region.

Hurtigruten Northern Lights

Why is a Hurtigruten voyage a good way to see the Northern Lights?

A voyage puts you in the auroral zone for several nights in a row, far from town lights, on a ship that keeps moving and can carry you away from local cloud. Crew announce sightings day and night, so you are not standing in the cold waiting, and you never have to drive icy roads in the dark.

• Several nights in the zone. A 12 day Coastal Express round voyage spends around six nights north of the Arctic Circle. A short city break gives you two or three, and one cloudy spell can wipe them out.
• Dark skies at sea. Away from port, the only lights are the ship's own and the odd farm on the shore.
• A moving viewpoint. Coastal cloud is often local, and a clear patch further up the coast is common.
• Someone else is watching. Hurtigruten says crew announce sightings to cabins at any time of day or night, and cabins and suites have a Northern Lights alert that you can switch on or off.
• Warmth on hand. When your fingers go numb, a hot drink and the panoramic lounge are a few steps away.
• Expertise. On the North Cape Line and Arctic Line the Expedition Team give lectures and guidance on deck, and the Astronomy departures carry a specialist astronomer.

Sail With Confidence

What is the Hurtigruten Northern Lights Promise?

The Northern Lights Promise covers qualifying Hurtigruten voyages of 11 days or more departing between 20 September and 31 March. If the aurora is not officially sighted during your voyage, meaning recorded by the ship's deck officers and announced to passengers, Hurtigruten gives you a free 6 or 7 day Coastal Express voyage the following season, depending on when you sail.

It applies to the 12 day Coastal Express round voyage, including the charter flight and Astronomy departures, the 15 day North Cape Line and the Arctic Line on qualifying dates. It does not cover shorter voyages such as the 8 day Arctic Circle Explorer, and the free voyage does not include flights. Full conditions are on our special offers page. It is not a guarantee that you will see the lights, which nobody can offer, but it shows how confident Hurtigruten is about eleven or more winter nights on this coast.

Getting There

Can you see the Northern Lights from the UK?

Occasionally, during strong geomagnetic storms, with the far north of Scotland the most likely place. Northern Norway sees the lights far more often, and you can fly there from the UK in just a few hours: around two hours from London to Bergen or Oslo, and around three and a half to four hours from London or Manchester to Tromsø.

Most of the time the UK lies well south of the auroral oval. On 10 and 11 May 2024, though, a storm at the top of the Kp scale, one of the most extreme the British Geological Survey has recorded in 155 years, brought the aurora across much of the country, including southern England. Nights like that are rare. For a realistic chance of seeing the lights overhead, you need to go north.

Northern Lights holidays from the UK

• Charter flights direct to Bergen. Selected winter Coastal Express round voyages on MS Kong Harald include a direct charter flight from Manchester, London Stansted or Newcastle, with transfers. See the Coastal Express with charter flights.
• Hurtigruten flight packages. Hurtigruten offers flight-inclusive packages on many voyages, using scheduled flights from London Gatwick, London Heathrow and Manchester, which may be indirect. Hurtigruten states that these packages come with ABTA and ATOL protection.
• Arranged by us. We can quote your voyage with flights, add hotel nights in Bergen, Oslo or Kirkenes, and put the whole trip together. Call 0333 405 0194.
• Your own flights. At the time of writing, Norwegian flies direct from London Gatwick to Bergen and to Oslo, and easyJet and Norwegian fly direct to Tromsø from London Gatwick and Manchester. Norwegian is also adding a twice weekly winter route from Glasgow to Tromsø, from 11 December 2026 to 22 March 2027. Schedules change each season, so check before you book.

As the Coastal Express calls at towns with airports all along the coast, you can also fly into Tromsø or Kirkenes and join a one way voyage. Our how to book page explains the options.

On The Night

How to see the Northern Lights: practical tips

Find somewhere dark with a clear view north, dress far more warmly than you think you need, give your eyes time to adjust and be patient. The lights often build slowly and then flare suddenly, so the people who see the best displays are usually the ones who stay out a little longer.

• Look north, then up. Displays often start as a pale arc low in the northern sky and then spread overhead, so keep turning round.
• Let your eyes adjust. It takes 20 minutes or more to adapt fully to the dark, so keep your phone screen dimmed.
• Do not dismiss a grey glow. A faint whitish band can be the start of a display. If a quick phone photo shows green, keep watching.
• Use forecasts, but do not rely on them. Aurora apps cannot see the cloud over your head. On the ship, the crew alert is the best forecast of all.

How to photograph the Northern Lights

• Keep it steady. Use a small tripod or brace the camera on a rail. On a ship, shorter exposures work better because the deck moves slightly.
• Go wide. A wide angle lens with the aperture fully open takes in more sky and the scenery below.
• Focus on infinity. Switch to manual focus and set it on a bright star or distant light.
• Exposure and ISO. Start with a few seconds, perhaps 2 to 8, at ISO 800 to 3200, and shorten the exposure when the lights are bright and moving fast.
• Flash off, and keep spare batteries warm in an inside pocket, as the cold drains them quickly.
• Phones. Most recent smartphones have a night mode that does a surprisingly good job if you hold them still.

Most of all, put the camera down for a while and simply watch. Photographs never quite capture the movement of a big display.

Weather and Packing

What is the weather like on the Norwegian coast in winter?

The Norwegian coast is much milder in winter than its latitude suggests, because the North Atlantic Current and its extension, the Norwegian Current, carry warmer water up the coast. Tromsø averages a few degrees below freezing in midwinter and Bergen a few degrees above, while inland areas at the same latitude are far colder.

Milder is not warm, though. A still night on an open deck with a sea breeze feels much colder than the thermometer says, and clear nights, the ones you want, are the coldest. Our climate and seasons guide has month by month detail.

What to pack for a Northern Lights trip

• Layers: a thermal base, a fleece or wool mid layer and a windproof, waterproof jacket.
• Hat, scarf and gloves, with thin liner gloves under mittens so you can work a camera.
• Warm, waterproof boots with a good grip, wool socks, and slip on ice grips for walks ashore.
• A head torch with a red light, which helps you see without spoiling your night vision.

Inside, the ship is warm and dress is relaxed. For snowmobile or husky excursions, warm outer clothing is often provided, but check the details when you book.
