HELP! IT'S FULL MOON! WILL IT RUIN MY AURORA EXPERIENCE?
Does the full moon cancel the northern lights? No
Can you still see them? Yes, if strong
What matters most? Clear skies
Imagine this: you’ve arrived beneath the auroral oval, solar activity is increasing, and the forecast looks promising — only to discover the sky is dominated by a bright full moon. Many travelers panic at this point. Will the moon wash out the Northern Lights?
The short, science-based answer: no.
The full moon does not affect aurora activity itself. What it can affect is human perception of faint displays — and even that depends on aurora strength, sky conditions, and experience.
At Aurora Reykjavík, we’ve observed and photographed thousands of aurora displays across all lunar phases. In this guide, we explain exactly when the moon matters, when it doesn’t, and why full-moon nights can actually create some of the most memorable aurora experiences in Iceland.

DOES THE FULL MOON EFFECT THE NORTHERN LIGHTS?
The moon has no physical effect on the Northern Lights.
Aurora borealis occurs when charged particles from the Sun interact with Earth’s magnetic field and atmosphere. This process is driven by solar wind and geomagnetic activity, not lunar phases.
A full moon only increases ambient light in the sky. This can make very faint auroras harder to notice, especially for inexperienced observers — similar to how moonlight reduces the visibility of dim stars.
FULL MOON – IT ALL DEPENDS ON THE STRENGTHS OF THE AURORA
That being said, as every stargazer knows, a full moon does cast a lot of light in the sky. And yes, for untrained eyes, it does make it harder to see the aurora, just as bright moonlight can drown faint stars from our view.
However, it all depends on how strong the display is that you are witnessing. A weak aurora might be drowned in bright moonlight, but if you get a moderate to a high level of solar activity, you will still get a good view of the northern lights. Contrary to what you might have heard, it is possible to see the aurora borealis, or northern lights, when there’s a bright moon, even a full moon, in the sky.
Moonlight matters when:
-
Aurora activity is weak (Kp 1–2)
-
The display is low on the horizon
-
The moon is very high up in the sky.
Moonlight does not matter when:
-
Aurora activity is moderate to strong (Kp 3+)
-
The aurora is overhead
-
Skies are clear and dark away from city lights

WHY WE LOVE FULL MOON FOR AURORA CHASING – AS PHOTOGRAPHERS
From years of photographing auroras across Iceland, we’ve found that full-moon nights offer several unique advantages — especially for photography and overall experience.
Many might think of moonlight as an obstacle, but for photographers and aurora enthusiasts, it brings some unique advantages. Here’s why we love full moon nights for Northern Lights hunting:
1. Moonlight Enhances the Landscape
The moon softly illuminates the foreground, creating a magical setting. Snow-covered mountains, lava fields, and Icelandic glaciers appear even more stunning under moonlight.
2. Beautifully Colored Skies
Instead of pitch black, the night sky appears in deep, rich blue hues—a striking backdrop for the aurora
3. Better Aurora Portraits
The moonlight adds just enough light to softly illuminate people in photos, avoiding the silhouette effect while maintaining the natural beauty of the aurora.
4. Shorter Shutter Speeds
Moonlight allows for shorter exposure times, making it easier to capture sharp images of people and realistic time-lapses that mimic real-time aurora movements.
5. Crisper Aurora Shapes
Shorter shutter speeds also capture the intricate shapes and patterns of the aurora with more clarity
6. Safer and More Enjoyable Conditions
Navigating Icelandic landscapes in the dark can be tricky. With a full moon, it’s easier to see your surroundings and avoid potential hazards like hidden lava caves or icy trails.
WHY THE MOON PHASE ALONE DOES NOT TELL THE WHOLE STORY
1. Moonrise and Moonset Matter More Than the Moon Phase
When planning a Northern Lights hunt, it’s not enough to look at the moon phase alone. Moonrise and moonset times are far more important. In many cases, especially around a full moon, the moon may set before aurora prime time – leaving the sky completely moonless during the best viewing hours around magnetic midnight. That’s why experienced aurora chasers always check when the moon is actually above the horizon. Tools like timeanddate.com provide precise moonrise and moonset times for any location and date.
A night labeled as “full moon” on the calendar can, in practice, have zero moonlight impact on your aurora experience.

2. Clouds Can Block the Moon While the Aurora Still Shines
Iceland’s weather adds another important variable: cloud cover.
It’s common to have partly cloudy skies, where low or mid-level clouds obscure the moon in one part of the sky, while clear gaps in another directions allow the aurora to shine through. In this situations, moonlight may be completely diffused or blocked, while the aurora remains visible – sometimes even more dramatically as green arcs illuminate breaks in the clouds. This is one of the reasons why cloud forecasts and on-site decisions matter far more than the moon phase alone.
3. Full Moon Nights Create Extra Opportunities for Astrophotography
For astrophotographers, full-moon nights offer additional creative opportunities beyond the aurora itself.
Moonrise and moonset during a full moon can produce:
- Dramatic low-angle moonlight over mountains and glaciers
- Golden or pastel tones near the horizon
- Unique compositions combining the aurora with lunar-lit landscapes
When times correctly, photographers can capture both aurora activity and moonrise or moonset at the same session, adding depth and storytelling in their images.

CONCLUSION: SHOULD YOU AVOID FULL MOON FOR NORTHERN LIGHTS CHASING?
Expert takeaway:
A full moon does not ruin Northern Lights viewing. What truly matters is:
-
Aurora strength
-
Cloud cover
-
Light pollution
-
Whether the moon is actually above the horizon
Pro tip: Track the aurora forecast and cloud cover on reliable apps, like the ones mentioned in our guide to Northern Lights apps, to plan your chase effectively.

FAQ ABOUT THE NORTHERN LIGHTS
Quand puis-je voir les aurores boréales en Islande ?
Can you see the Northern Lights during a full moon?
What time do the northern lights show up?
During the winter months, when the hours of light are limited, the northern lights can often appear as early at 7:00pm.
As the exact time of an Aurora display cannot be predicted, keep your eyes at the sky. And remember, patience is key!
How long do the northern lights last?
Each northern lights display is different, and varies in duration. Furthermore, the northern lights are not always visible for the entire duration of a single Auroral episode: they often change in intensity throughout a single display, and can go from very bright to incredibly faint, to the point they are hardly visible at all any more.
Learn more about how the northern lights behave duration-wise here.
Can I see the northern lights when it is cloudy?
As long as we can find some gaps in the cloud cover, some windows of clear sky – there’s hope.
And, even when it’s cloudy, keep in mind that not all clouds are the same. For example, high clouds are often see-through and do not necessarily disrupt our view. Rule of thumb: if you can see the stars, you can potentially see the northern lights too.
Once again, keep your eyes at the sky et check the forecast regularly for the most reliable prediction.
Do the northern lights only appear when it is cold?
As you can imagine, this means that you don’t need cold temperatures to see an Aurora (although you should not expect t-shirt weather at night in Iceland, not even in August).
The northern lights happen way above the weather systems, and are not influenced by weather systems and temperature fluctuations in the lower atmosphere.

Are the northern lights visible all over Iceland?
In the Arctic region, the belt extends between 60°N and 70°N latitude. As Islande in its entirety is included between 63°N and 67°N, and therefore well within the aurora belt, chances of seeing the northern lights are virtually the same everywhere around the island – if weather allows.
That said, the likelihood of witnessing the northern lights is higher away from the city lights, and some areas around the country are especially scenic. Here are our favourite locations for northern lights spotting in Iceland.
