Northern Lights
Compare destinations and months using historical cloud conditions, calculated darkness and moon phases, and clear explanations of tour terms. These help you plan; they do not predict an aurora sighting.

Where to see the northern lights
What travellers say
Nobody can promise you the aurora
Booking a night under the northern lights means buying something nobody can promise. The industry knows this and sells the word guaranteed anyway, alongside percentages that no one states the method for.
We explain the source, counting rule and limits alongside our comparisons. Historical cloud calculations are planning aids, not measured sighting rates. Where a source description or method needs correction, we say what changed.
Picked by our editors for you
Six nights we would book ourselves, one for each country we cover.
Northern Lights Adventure with Greenlander, Maximum 8 People
A working chase in a modified 4x4 Mercedes: hot meal, tripods, thermal suit and aurora portraits. Expect snow underfoot and a genuinely late finish.
Yellowknife Aurora Hunting by Bus with Wilderness First Aid Guides
Every guide is trained in wilderness first aid, the line worth reading twice for a tour that parks in territorial parks in midwinter. Small groups.
Kiruna Northern Lights Chase with a Photographer, Lights of Vikings
Abisko, the boreal forest, or anywhere with a gap in the cloud: this operator built its name on driving far for clear sky. Photographs sent within three days.
Small Group Northern Lights Hunt from Rovaniemi with Pro Photos and Video
Unlimited photographs and video on astrophotography gear, eight guests at most, and a start time that moves between 16:00 and midnight with the solar wind.
Electric Moose Studios Aurora Tour with Studio Portraits and Hot Pizza
Controlled studio lighting is why these portraits are not silhouettes, from a photographer who shot weddings for ten years before turning to the aurora.
Small Group Northern Lights Jeep Tour with an Icelandic Guide and Photos
Vikings, Norse gods and the elves Icelanders are still careful about fill the road time, and the guide works the camera too. Free retry if luck goes wrong.
Ratings collected by Viator and Tripadvisor
Start with the question you actually have
Six sections. The first two are where the numbers live.
Plan your trip
When to go, how much real darkness you get, which nights the moon takes away, and what to wear when you stand still for six hours in the cold.
Where to go
Tromso, Reykjavik and Rovaniemi compared on historical cloud conditions, darkness and geomagnetic latitude, plus other destinations worth comparing.
Choosing a tour
What a guarantee actually covers, why a two-hour cruise and a ten-hour chase share the same title, and the complaints that repeat in bad reviews.
How the aurora works
The physics that changes decisions: the oval, why the Kp index misleads, and why the colour depends on how long an atom stays excited.
Photographing the aurora
Why your eyes see grey and the sensor sees green, what a phone can really do, and the settings that hold up at minus twenty.
Culture and curiosities
What people believed before anyone knew, the sound the Sami named it after, and a glossary of the words forecasts never define.
The number that changes a booking
December has Tromsø’s weakest cloud result
Long nights and favourable cloud conditions do not necessarily coincide. Compare both when choosing your dates.
In our published Tromsø table, December has 8.0 hours of astronomical darkness within the sampled window but the lowest share of nights passing the cloud rule. September has a higher qualifying share and under two hours of astronomical darkness on average. These are historical cloud comparisons and approximate darkness calculations, not sighting forecasts.
Use the comparison to choose a trade-off, then check the weather and local conditions for your trip.
How we handle numbers
Cloud cover at a fixed location and sightings on a tour measure different things. Before comparing percentages, check the place, period, threshold and whether the tour can move. Our method and its limits explains what the historical tables can and cannot tell you, including a correction to the source description.
Tour pages show prices supplied by our booking partners. Our price guide compares published median prices with their sample sizes and snapshot date. Those historical medians are not current quotes; check the selected date and final price with the booking partner before paying.
Editorial
From the season
Dated writing, kept separate from the guide so the guide stays current.
Abisko's Blue Hole Is Where Our Own Method Stops Working
The clear-sky window Abisko is sold on is smaller than anything our gridded cloud data can resolve: five sample points within 25 km do not separate. What would settle it is thirty-nine years of hourly cloud observations in SMHI's open archive, recorded in the village itself.
A Meteor Shower and the Northern Lights, Same Night: One Sky Works Against the Other
The Geminids peak over aurora country on 13-14 December 2026. From Tromso the radiant never climbs past 53 degrees, and a bright aurora is a lamp. The formula behind every published meteor rate says what each of those costs you.
We Read Eight Aurora Guarantees in Full. Not One Promises You the Sky
Two Reykjavík operators share one sentence: low-level lights count as sightings. We read eight aurora guarantees in full on 14 October 2026. Not one promises the aurora, five rule out refunds in near-identical words, and the expiry date decides the value.
Three things worth knowing before you book
Book more than one night. Prefer a tour that can drive out from under the cloud. Consider the shoulder season, which is cheaper and usually clearer.
