Northern Lights guide
Everything you need to know before you go, including what no tour can promise.
When can you see the Northern Lights in Iceland?
The season runs roughly from September to mid-April, when the nights are dark enough. In summer the sky never gets dark, so the aurora can't be seen.
Three things must come together: darkness, clear skies and solar activity. Even in Iceland the lights can be shy, which is why patience matters and why a free retry on some tours is so valuable.
How do forecasts work?
The Icelandic Met Office publishes an aurora forecast with cloud cover at en.vedur.is/weather/forecasts/aurora. Clouds are usually the biggest problem, more than solar activity.
Tour guides check cloud and aurora forecasts every evening and drive to wherever the sky is clearest, sometimes up to two hours from Reykjavík.
Why take a tour?
A guide knows where the sky is clear, handles the driving on winter roads and takes you away from city lights. Many tours also include extras such as hot chocolate, blankets and photos.
What to wear
Standing still at night in winter is colder than you expect. Dress in layers:
- Thermal base layer and a wool or fleece mid-layer
- Windproof and waterproof outer layer
- Warm hat, gloves and scarf
- Thick socks and sturdy, warm boots
Photographing the aurora
A tripod is the most important tool, because you need long exposures. With a camera, try a wide lens, the widest aperture, ISO 1600–3200, a 5–15 second shutter and manual focus on infinity. On a phone, use night mode on a tripod or a steady surface. Cold drains batteries fast, so keep spares warm in an inside pocket.
Book early in your trip
Clear nights can't be predicted far ahead. Booking your tour at the start of your stay leaves time for another try if the weather or the lights don't cooperate.
Common questions
Are the Northern Lights guaranteed?
No. They depend on weather and solar activity, and no honest operator can guarantee them. Many tours offer a free retry if none are seen; check the tour page for details.
Can I see the Northern Lights in Reykjavík?
Sometimes, on strong nights, but city lights make it harder. Tours take you away from the lights, which greatly improves your chances.
How long is a Northern Lights tour?
Most evening tours last about 2.5 to 5 hours. Boat tours are shorter, and some combination tours run for a full day.
Are toilets available on tour?
Facilities outside urban areas are very limited, so plan ahead before you depart.
