Quick photography tips
If you want photos, the essentials are simple: a tripod (for long exposures) and ideally a wide-angle lens to capture both sky and landscape.
The Northern Lights are one of nature’s most impressive light shows and a highlight of winter travel in Iceland. Also known as the aurora borealis, they appear when electrically charged particles from the sun travel toward Earth and collide with atoms and particles in the upper atmosphere. Those collisions release energy as light. The colours you see depend on which gases are excited and at what altitude: oxygen typically produces the most common green/yellow-green tones (around 90–200 km), while nitrogen can create blue, purple, and red hues.
When can you see the Northern Lights?
In Iceland, aurora viewing is most promising from September through April, when nights are long and dark. They can also be visible as early as August, as soon as the sky becomes dark enough and conditions are favourable.
What matters most is not a specific month, but the combination of:
- Darkness
- Clear skies (low cloud cover)
- Low light pollution
- Aurora activity (solar conditions)
How to improve your chances
Check the forecast before you go. In Iceland, two of the most useful tools are:
- Icelandic Met Office aurora forecast: (activity + cloud cover)
- Iceland at Night: with real-time info and practical tips (including photography guidance)
Go where it’s dark. Even a short drive away from town lights can make a big difference. South Iceland is especially well-suited because it combines accessible roads with wide, open landscapes—ideal for scanning the sky.
How to plan a Northern Lights night in South Iceland
South Iceland is ideal for aurora viewing because it offers wide-open landscapes and many areas with minimal light pollution—while still being accessible from the Ring Road. The most effective approach is to treat the aurora as a flexible evening activity:
- Choose a base
- Check cloud cover and aurora activity in the late afternoon and again after dinner.
- Drive to clearer skies (sometimes 20–60 minutes makes all the difference).
- Give it time: stay out for a while, scan the whole sky, and be patient—auroras can strengthen suddenly.
Northern Lights and your South Iceland itinerary
Aurora hunting is easy to combine with daytime sightseeing: explore waterfalls, glaciers, geothermal areas, or towns during the day, then head out after dark when the forecast looks promising. You can weave Northern Lights viewing into any of our four main travel routes:
The Volcanic Way - The Golden Circle - The South Coast - The Lighthouse Trail
