Northern Lights in Iceland: Complete Aurora Guide

The Northern Lights in Iceland

The Northern Lights, or aurora borealis, are one of nature's most awe-inspiring phenomena. Iceland, positioned just below the Arctic Circle, is one of the world's premier destinations for viewing this celestial light show. The combination of dark winter skies, minimal light pollution outside Reykjavik, and accessible viewing locations makes Iceland an ideal base for aurora hunting.

What Causes the Northern Lights?

The aurora borealis is caused by charged particles from the sun (solar wind) colliding with gases in Earth's atmosphere. When these particles, guided by Earth's magnetic field towards the poles, strike oxygen and nitrogen molecules, they release energy in the form of light. Oxygen produces green and red colours, while nitrogen creates blue and purple hues. The result is a shimmering curtain of light that dances across the sky in patterns that are never the same twice.

The intensity of the Northern Lights depends on solar activity. The sun follows an approximately 11-year cycle of activity, with periods of high activity (solar maximum) producing more frequent and vivid auroras. However, even during solar minimum, the Northern Lights are regularly visible in Iceland. The current solar cycle is approaching its maximum, making the coming years an excellent time to visit.

When to See the Northern Lights in Iceland

The Northern Lights are visible in Iceland from September through April, with peak viewing from October to March. The key requirements are darkness and clear skies. During Iceland's summer, the midnight sun prevents aurora viewing even when solar activity is high.

September-October: The Northern Lights season begins. Nights are getting longer but temperatures are still relatively mild (2-8°C). Autumn storms can bring cloud cover, but clear nights often produce excellent displays.

November-January: The darkest months, with only 4-6 hours of daylight. This means more potential viewing hours, but also the coldest temperatures (-5 to 3°C) and more frequent cloud cover.

February-March: Days are lengthening but still dark enough for aurora viewing. Often considered the sweet spot: reasonable temperatures, increasing daylight for daytime activities, and statistically some of the best aurora activity.

April: The last month of the season. Nights are getting short, but strong solar events can still produce visible auroras in the few hours of true darkness.

Where to See the Northern Lights

The most important factor is escaping light pollution. While the Northern Lights can occasionally be seen from Reykjavik, the city's lights significantly reduce visibility. The best viewing locations are at least 30-45 minutes from the city.

The Golden Circle area: Þingvellir National Park is one of the most popular aurora viewing spots, combining dark skies with a dramatic landscape of tectonic fissures and still water for reflections.

Reykjanes Peninsula: The area between Reykjavik and Keflavik Airport offers dark skies and dramatic volcanic landscapes as foreground for aurora photography.

Vik and the South Coast: The black sand beaches and sea stacks of Reynisfjara provide stunning foreground elements for aurora photos.

Snaefellsnes Peninsula: Kirkjufell mountain near Grundarfjörður is one of Iceland's most photographed aurora locations.

North Iceland: Akureyri and the Mývatn area offer excellent viewing with even darker skies than the south, though they require more travel time from Reykjavik.

How to Photograph the Northern Lights

Capturing the aurora on camera requires some preparation, but modern cameras make it more accessible than ever.

Camera settings: Use manual mode. Set ISO to 1600-3200, aperture to the widest available (f/2.8 or lower is ideal), and shutter speed to 8-15 seconds. Use manual focus set to infinity. A tripod is essential for the long exposures required.

Composition: Include interesting foreground elements like mountains, churches, water reflections, or lava formations. The aurora alone makes a good photo, but a compelling foreground makes a great one.

Smartphones: Modern smartphones (iPhone 12 and newer, Samsung Galaxy S21 and newer) can capture the aurora using their night mode. Results are not as detailed as a dedicated camera, but they can produce impressive images. Use a phone tripod or prop your phone against a stable surface.

Batteries: Cold temperatures drain batteries rapidly. Keep spare batteries warm in an inside pocket and swap them when the active battery runs low. Bring at least two spare batteries for a full evening of shooting.

Northern Lights Tours from Reykjavik

While you can hunt for the Northern Lights independently, a guided tour significantly increases your chances of success. Experienced guides use real-time aurora forecasts, satellite cloud cover data, and years of local knowledge to find the best viewing conditions each night.

Our Northern Lights Minibus Tour takes small groups to the best locations, with hot chocolate and Icelandic snacks included. For photographers, our Northern Lights Photography Tour provides tripods, camera settings assistance, and extended shooting time with a professional photographer guide.

All our Northern Lights tours include a free rebooking guarantee: if the aurora is not visible, you can join another tour at no extra charge for the duration of your stay.

Aurora Forecasts and Apps

Several tools help predict Northern Lights activity:

• Icelandic Met Office (vedur.is): Provides a combined aurora and cloud cover forecast specific to Iceland. This is the most useful single resource.
• NOAA Space Weather Prediction Center: Provides global aurora forecasts and real-time solar wind data.
• My Aurora Forecast app: A user-friendly mobile app with push notifications when aurora activity is high.
• KP Index: A scale from 0-9 measuring geomagnetic activity. KP 3 or higher generally produces visible aurora in Iceland. KP 5+ produces spectacular displays.

Tips for Success

• Stay in Iceland for at least 3-4 nights to maximise your chances. One clear night is usually enough.
• Be patient. The aurora can appear suddenly after hours of quiet sky, or it may build gradually.
• Dress extremely warmly. You will be standing outside in the cold for extended periods. Multiple thermal layers, insulated boots, and hand warmers are essential.
• Let your eyes adapt to the dark for 15-20 minutes before judging visibility. The aurora is often more visible to the naked eye once your eyes have adjusted.
• The camera sees more than the eye. If you think you see a faint green glow, take a long-exposure photo. The camera will reveal colours and detail invisible to the naked eye.
• Do not rely on a single night. Weather and solar activity are unpredictable. Build flexibility into your itinerary.
