Northern Lights in Trondheim

On a Quest for the Aurora?

The Northern Lights, also known as the Aurora Borealis, often comes out to play during the winter months in Trondheim. But how do you know when and where to see it? Below we have a breakdown of how to maximize the probability of seeing it (depending on the forecast).

What is a KP-Index?

In short, this is an Aurora forecast that notifies you how strong the Northern Lights will be on a scale from 0 to 9. The lower the number on the KP index, the weaker the chance of seeing the Northern Lights will be and the further North you have to go in order to see it. If the forecast predicts KP 9, that is a very high probability where the dancing lights can even be seen as far South as France! We may be lucky to see it in Trondheim at KP 2 and 3, but then it will be weak. A KP 4 and up is a solid forecast and a high probability of seeing it in Trondheim as long as the sky is clear.

Note! Even if a high KP is predicted, it is also required that the weather is in sinc and there is a cloudless sky.


When is Aurora Season in Trondheim? What Time of Day?

The best time in the year to see the Northern Lights in Trondheim is from September to March when the sky is pitch black.

Patience is required when going on a hunt for the Aurora. The Northern Lights are not static, but constantly changing and shifting. Even if you have confirmed a high KP index on a cloudless night and have found a good place to sit in the dark, the Northern Lights can come and go. And if you are not patient you can miss it. No one knows for sure what time it will come. Our tip is to bring something good to eat and drink, as well as warm clothes and wait for the lights to appear. As the saying goes, “good things come to those who wait”…

“Sometimes it can be early in the evening, sometimes late after midnight, but my experience with the Northern Lights during my 10 years of doing this is that the best time is very often between 7pm and midnight”

Note! You must give your eyes time to adjust to darkness in order to see the Aurora.

Where are the Best Viewpoints?

As a rule of thumb, it is wise to find a place where you have a good view to the North and where there is minimal light pollution (ex. city lights). It may still be possible to see the northern lights from Trondheim city center if the KP number is high enough.
