FAQ: Northern Lights Forecast and predictions


1. How to predict aurora in Iceland?

To predict auroras in Iceland, monitor real-time aurora forecasts and geomagnetic activity reports. Websites and apps dedicated to aurora forecasts provide KP index predictions and cloud cover information, which are essential for predicting visibility in Iceland.


2. How far in advance can auroras be predicted?

Auroras can generally be predicted a few days in advance, with more reliable short-term forecasts available 30 minutes before. Long-term predictions are less accurate due to the variable nature of solar activity.


3. What is the best tool for predicting the Northern Lights?

The best tool for predicting the Northern Lights is a combination of KP index forecasts, solar wind data, and real-time geomagnetic monitoring. Apps and websites specialising in aurora forecasts, like the NOAA Space Weather Prediction Center, are valuable resources.


4. What’s the difference between active and quiet aurora forecasts?

‘Active’ aurora forecasts indicate a high likelihood of geomagnetic activity, leading to more vibrant and widespread auroral displays. ‘Quiet’ forecasts suggest low geomagnetic activity, resulting in fainter or no visible auroras.


5. What factors affect the accuracy of aurora forecasts?

Aurora forecast accuracy is influenced by the unpredictability of solar wind speed, solar flares, and geomagnetic activity. Earth’s weather, such as cloud cover and light pollution, also affects visibility, making precise prediction challenging.


6. How does the cloud cover forecast work?

The single most important factor contributing to successful Aurora Hunting is the cloud cover. The colours in the cloud cover forecast represent different cloud layers:

  • Low level clouds are presented as blue to purple.
  • Mid level clouds are presented as orange to red.
  • High level clouds are presented as green.

For planning a successful Northern Lights hunt, consult the cloud cover forecast, noting that grey or coloured shades indicate poor night sky visibility and white signifies clear skies. Remember, clouds can change quickly, and while forecasts are helpful, satellite images provide more accurate, real-time information.


7. Why do aurora forecasts use the KP index?

The KP index measures geomagnetic activity and is used in aurora forecasts as it directly relates to the strength of auroral displays. Higher KP values (4-9) indicate stronger geomagnetic storms and a higher likelihood of visible auroras.


8. Is KP 5 good for aurora?

Yes, a KP 5 is considered good for observing the aurora or the Northern Lights. For countries like Iceland, which is situated at a high latitude and directly in the Aurora Belt, even a lower KP index, such as KP 1, can provide a spectacular show of the Northern Lights. This is due to Iceland’s geographical position close to the Arctic Circle, enhancing the likelihood of aurora sightings even during lower geomagnetic activity.


9. Can solar flares predict aurora activity?

Yes, solar flares can predict aurora activity. Large solar flares can eject solar particles towards Earth, triggering geomagnetic storms that enhance aurora visibility. However, not all solar flares lead to visible auroras.


10. How do moon phases affect aurora viewing?

Moon phases affect aurora viewing by influencing the amount of natural light in the sky. A full moon can brighten the sky, making faint auroras harder to see, while a new moon provides darker skies, ideal for observing auroras.


11. Is geomagnetic latitude important for aurora predictions?

Yes, geomagnetic latitude is crucial for aurora predictions. Areas closer to the geomagnetic poles have a higher probability of aurora sightings. Geomagnetic latitude, different from geographic latitude, aligns with Earth’s magnetic field.


12. Can we predict the colour of the Northern Lights?

Predicting the exact colour of the Northern Lights is difficult. The colours depend on which atmospheric gases are ionised by solar particles and the altitude of these interactions. Green is the most common, with red, purple, and blue less frequent.


13. How long do the northern lights last?

The duration of a Northern Lights display can vary significantly, from a few minutes to several hours. However, most auroras last between 15 minutes to an hour.


14. Do Northern Lights make noise?

Scientifically, the Northern Lights are silent. Any noises associated with them are likely caused by natural surroundings or are a sensory phenomenon known as auroral sounds, which are not yet fully understood.


FAQ: How, when and where to see the Northern lights


15. Can I see aurora with my eyes?

Yes, you can see the aurora with the naked eye once they are adjusted to the dark. The lights often appear as a faint glow initially and can intensify into vibrant colours, depending on the strength of the geomagnetic activity.


16. How do you spot the Northern Lights?

To spot the Northern Lights, find a location with dark, clear skies away from light pollution with an open view towards the northern horizon, get your eyes adjusted to the dark, and look for a faint green coloured light appearing low on the north horizon.


17. Is it guaranteed to see northern lights in Iceland?

There is no guarantee to see the Northern Lights in Iceland as their visibility depends on solar activity and weather conditions. However, visiting during the aurora season (September-April) increases your chances.


18. Which direction should I look for the aurora?

In the Northern Hemisphere, look towards the northern horizon for the best view of the aurora. The lights typically appear in an oval shape around the magnetic pole, so facing north increases your chances of seeing them.


19. Do the Northern Lights happen every night?

The Northern Lights occur most nights but are not always visible. Visibility depends on geomagnetic activity and local weather conditions. Clear, dark skies and higher solar activity increase the chances of seeing the lights.


20. What’s the best time to see the northern lights?

Observations show that on average, you are about twice as likely to see auroras around the equinoxes than around the solstices. So, the months of March/April and September/October are often the best bet. But don’t worry if you are visiting sometime in the winter between October and March.

During the equinoxes in March and September, the alignment of Earth’s magnetic field with the interplanetary magnetic field (IMF) enhances geomagnetic activity, increasing the chances of witnessing the Northern Lights in Iceland. Although these periods have more daylight than the darker months of November to February, the nights remain sufficiently dark for aurora viewing. Additionally, the weather in March and September is often more favorable compared to the harsher conditions in December and January, providing clearer skies and better viewing opportunities. This combination of factors makes the equinoxes an opportune time for observing the Northern Lights, despite the shorter nights.


21. What month is best to see the northern lights in Iceland?

The best months to see the Northern Lights in Iceland are from September to April, with peak visibility often occurring during the equinox months of September/October and March/April.


22. What is the best time of night to see the Northern Lights?

The best time to see the Northern Lights is typically between 9 PM and 2 AM. This is when the sky is darkest, increasing the likelihood of observing the auroras clearly.


23. How can I see aurora today?

To see the aurora today, check current aurora forecasts and solar activity reports. Choose a location with clear, dark skies away from city lights. The likelihood of seeing the aurora varies with geomagnetic activity and weather conditions.


24. How long do you need in Iceland to see the Northern Lights?

To increase your chances of seeing the Northern Lights in Iceland, plan a stay of at least one week. This duration allows for variability in weather and solar activity.


25. Is now a good time to see the northern lights in Iceland?

The current suitability for seeing the Northern Lights in Iceland depends on real-time solar activity and weather conditions. Generally, September to April offers the best chances, but always check current forecasts.
