The Northern Lights (Aurora Borealis) are caused by charged particles from the Sun hitting Earth’s atmosphere. The Sun follows an 11-year cycle of activity, and 2025-2026 is near the solar maximum – meaning more frequent and intense displays. People as far south as northern Germany and the UK have been seeing them. If there was ever a year to go hunting, this is it.
When to Go
| Month | Likelihood | Notes |
|---|---|---|
| September | ⭐⭐⭐ | Season starts. Less cold. Equinox boosts activity. |
| October | ⭐⭐⭐⭐ | Great month. Dark enough, not too cold. |
| November | ⭐⭐⭐⭐ | Reliable. Snow adds to the photography. |
| December | ⭐⭐⭐ | Darkest month. But cloudiest (especially in Norway). |
| January | ⭐⭐⭐⭐ | Cold but clear. Excellent aurora conditions. |
| February | ⭐⭐⭐⭐⭐ | Best month overall. Long nights, clearer skies. |
| March | ⭐⭐⭐⭐⭐ | Equinox again. Last month of reliable displays. |
Best Locations
🇳🇴 Tromsø, Norway
- Why: The “Capital of the Arctic.” Inside the aurora zone. Direct flights from London, Oslo, and Stockholm.
- Best experience: Book a guided aurora chase (minibus drives to wherever skies are clearest). Tours run €150-200/person and include hot drinks and photography help.
- Budget tip: Stay at a hostel (€40/night). The city center has great restaurants and a vibrant nightlife for its size.
🇮🇸 Iceland (Reykjavik + Beyond)
- Why: The entire country is in the aurora zone. Combine with geysers, hot springs, and glaciers.
- Best experience: Self-drive the Golden Circle or Snæfellsnes peninsula. Stop at any dark spot when the Kp index spikes.
- Budget tip: Iceland is expensive. Sleep in a campervan (from €80/night in winter including insurance) to save on hotel costs.
🇫🇮 Finnish Lapland (Rovaniemi, Inari, Saariselkä)
- Why: Glass igloos and aurora cabins – lie in bed and watch the lights through the ceiling. The most comfortable aurora experience.
- Best experience: Book a glass igloo at Arctic SnowHotel (Rovaniemi) or Kakslauttanen Arctic Resort (Saariselkä). They have aurora alarms that wake you up when the lights appear.
- Budget tip: Stay in Inari (less touristy than Rovaniemi) for 30-40% cheaper accommodation.
🇸🇪 Abisko, Sweden
- Why: Statistically the clearest skies in Scandinavia. The “blue hole of Abisko” is a microclimate phenomenon that keeps skies clear when surrounding areas are cloudy.
- Best experience: Abisko Aurora Sky Station. Take the chairlift up, watch from above the cloud line. Magical.
How to Forecast the Aurora
- Kp Index: The standard aurora forecast scale (0-9). Kp 3+ means visible from northern Scandinavia. Kp 5+ means visible from Scotland/northern Germany. Kp 7+ means visible from central Europe.
- NOAA Space Weather: The official 30-minute forecast. Check it religiously.
- Apps: “My Aurora Forecast” (free, simple), “Aurora” by TINAC (beautiful interface), “SpaceWeatherLive” (most detailed data).
Photography Tips
- Camera settings: ISO 1600-3200, aperture f/2.8 or wider, shutter speed 8-15 seconds. Use a tripod.
- Phone photography: Night mode on iPhone 15+ and Samsung Galaxy S23+ can capture decent aurora shots. Use a phone tripod.
- Pro tip: The aurora often looks more green to cameras than to the naked eye. Adjust your expectations – in person, it can appear as a whitish-green glow, especially for faint displays.
- Batteries die in the cold. Bring 2-3 spares and keep them in your inner jacket pocket (body heat preserves charge).
What to Wear (-20°C Survival Kit)
- Base layer: Merino wool thermals (top + bottom)
- Mid layer: Fleece jacket + down vest
- Outer layer: Waterproof/windproof jacket + insulated pants
- Extremities: Thick wool socks + insulated boots, fleece-lined gloves (get touchscreen-compatible ones for your phone), warm hat, neck gaiter
- Hand warmers: Disposable hand warmers (€1/pack) – put them in your gloves and boots
Hidden Aurora Locations Beyond the Famous Spots
If you want to avoid the crowds at Tromsø and Reykjavik, these lesser-known destinations offer equally good (sometimes better) aurora viewing:
- Alta, Norway: Fewer tourists than Tromsø, equally inside the auroral oval, and home to the world’s only permanent aurora exhibition (the Northern Lights Cathedral). The surrounding landscape – frozen fjords and dog-sled routes – adds to the experience.
- Inari, Finland: A tiny village in Finnish Lapland on the shores of Lake Inari. Far less touristy than Rovaniemi, 30–40% cheaper accommodation, and the Sámi cultural experiences here (reindeer herding, Sámi parliament) are authentic and fascinating.
- Svalbard, Norway: For the truly Arctic experience. At 78°N, Svalbard sits directly under the aurora oval. You can see the northern lights even at noon in midwinter (it’s polar night). The main town, Longyearbyen, has just 2,400 residents, polar bears, and extraordinary dark sky photography conditions.
- Greenland (Kangerlussuaq): One of Earth’s clearest skies due to the polar desert climate. Almost no light pollution. An emerging aurora destination for adventurous travelers willing to pay premium prices for truly extraordinary conditions.
Sample 3-Night Tromsø Aurora Chase Itinerary
- Day 1 (Arrival): Fly into Tromsø Airport (direct flights from Oslo, London, and Stockholm). Check into hostel or hotel. Download aurora apps and check the evening forecast. If Kp index is 3+, drive 20 minutes outside the city to the nearest dark area after 9pm.
- Day 2: Day trip to the Lyngen Alps (1 hour by minibus). Snowshoeing or dog sledding. Return at dusk. Book a guided aurora chase minibus tour (€150–€200/person) – the guide drives wherever the skies are clearest that night, chasing breaks in cloud cover.
- Day 3: Visit the Arctic Cathedral and the Polaria aquarium. Cable car up Storsteinen mountain for city views. Final aurora check late evening – if Kp is high, this is your best last chance.
Frequently Asked Questions
Can I see the northern lights from the UK? Yes, during strong solar events (Kp 5+). The best spots are northern Scotland, Orkney, and the Shetland Islands. In 2025, the lights were visible as far south as London during an exceptionally strong geomagnetic storm. Use the “My Aurora Forecast” app with location alerts.
What if it’s too cloudy to see them? Cloud cover is the aurora hunter’s biggest enemy. The strategy is mobility – book a guided tour whose driver will chase clear skies by car or snowmobile. Alternatively, choose Abisko in Sweden, which has a statistically clear microclimate above the clouds.
Is the aurora actually green in real life? The aurora is often more visual when photographed than seen with the naked eye. The human eye is less sensitive to green at low light levels, so what looks like a faint whitish glow on a good night turns vivid green in a 10-second camera exposure. During very strong displays (Kp 7+), the colors are unmistakably vivid even with the naked eye.
