There have been many wonderful northern lights shows in the last years and more are coming? Do you want to see a spectacular show like the one in 10th May 2024? It was a night that the whole world will remember for a long time! We witnessed the strongest aurora borealis and australis in 21 years! It was so strong that aurora was visible as south as in Florida or on the Canary Islands. It means that basically everyone in the whole Europe and the whole US could see this fantastic phenomenon if there was a clear sky. I myself watched northern lights in Stockholm where the sky was on fire and I could even see the dancing in all possible colours with the naked eye! Would you like to see similar northern lights in the future? Follow my tips and tricks as well as tips for guiding tours and best accommodations to see the northern lights around the world at the end of the article.
Unique real time northern lights movie from Stockholm
The strong northern lights event of 10th May 2024 was spread across media all around the world and it was unique by its strength. But did you know the aurora shows are happening much more often? I managed to record a fantastic northern light show on my camera on 14th January 2022 and it was also visble across half of Europe and the US and only a few people knew about it. I got many nice comments but unfortunately also many sad messages: “I missed it. When and where can I see the northern lights next time? How did you know there will be aurora borealis that day?” I decided to help out and write this guide. This is all you need to know this fantastic phenomenon.
What are northern lights?
To understand when and how you can witness northern lights, you have to know first what the lights actually are and how they are caused. First, let’s take a look at the official Wikipedia definition:
“Auroras are the result of disturbances in the magnetosphere caused by solar wind. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying colour and complexity.”
In simple words: northern lights are caused by solar activity which reaches our planet via charged particles and they react with the Earth’s magnetic field. The reaction causes lights nearby the magnetic poles of our planet (which are nearby the actual North and South Pole). The animation below will make it even more clear:

Why is it important to know this to forecast northern lights? It’s easy. By observing the Sun we can predict the aurora activity. Strong northern lights usually occur after unusual activity on the Sun (to make it simple let’s call them eruptions) and it takes approximately 3 days until the charged particles reach our atmosphere and cause the northern lights.
What is Aurora Borealis and Aurora Australis?
Aurora Borealis is simply another term for northern lights. It means the same, just a more fancy and epic name 🙂 But did you know that there are also southern lights? The reaction between solar activity Earth’s magnetic field causes lights also in the south so southern lights can be seen from the south of South America, Australia and New Zealand. These lights are called Aurora Australis.
The term aurora occured first in 1619 when Galileo named these fascinating lights according to the Roman Aurora, goddess of the dawn. On the contrary, the words borealis and australis are coming from Greek mythology. These name are derived from ancient gods – specifically of the north wind (Boreas) and the south wind (Auster).
What time of the year is the best to see northern lights?
This is a very frequent question on social media under northern lights related topics and I often see random answers such as: “You can see them from January to March because it’s the coldest.” Bullshit. In fact you can see aurora borealis basically anytime when the sky is dark, when there are no clouds, and when the Sun is active.
The Sun doesn’t really think of when to make the largest eruptions based on the position of the Earth. The solar eruptions happen through the whole year, so be ready to see aurora anytime when there is dark sky if you live in Stockholm or even more north. I have seen the earliest aurora in the middle of August and the latest at the end of April. Check out the sunrise and sunset times for Stockholm. You can also insert your city in the link to see the results for you. The auroras can be seen during night and astronomical twilight.
If you are making a trip with the main purpose to see aurora, then plan it so you have a statistically bigger chance to see northern lights. Remember:
- The longer the nights last, the bigger chance to see it.
- Consider also the climate. Choose months with less cloudy/rainy/snowy days.
- Warmer days are also giving you a higher chance since you will be willing to wait longer outside for northern lights to show up compared to when it is -20.
- Choose a time when there is no full moon. Moonlight is very strong and makes it more difficult to see aurora.
Where in Europe and America is it the best to watch northern lights?
The auroras usually occur behind the polar circle but are more rare in the south. The geomagnetic activity is measured by the so called Kp index. It is a scale of numbers between 0-9. Using this scale, it is easy to determine what Kp number you need to have a chance of seeing auroras where you are (read more about the Kp index here). These are the values to follow for cities across Sweden.
- Kp 1: Kiruna, Narvik, Rovaniemi (Europe), Fairbanks, Whitehorse (Northern America): happens almost every day
- Kp 3: Ålesund, Sundsvall, Jyväskylä (Europe), Calgary, Thunder Bay (Northern America): happens usually a few times every week
- Kp 5: Stockholm, Helsinki, Oslo, north of Scotland (Europe), Seattle, Toronto, Halifax (North America): happens usually 1700 times during one solar cycle – ca 11 years. In 2022, northern lights were reported visible 42 times in Stockholm or more in the south! It’s pretty often!
- Kp 7: London, Brussels, Cologne, Warsaw (Europe), Salt Lake City, Denver, Nashville (Northern America: happens usually 200 times during one solar cycle
- Kp 9: Barcelona, Marseille, Rome, Bucharest (Europe), Miami, Houston, Los Angeles (usually 4 times during one solar cycle)
The Kp 1 is common. It means you can see the northern lights fir instance in Kiruna almost every day. The more south you are, the less often you will have the chance. Keep in mind that these numbers don’t guarantee aurora. Forecasts are not 100% correct and there are of course exceptions. I have seen northern lights in Stockholm when there was Kp 3 shown in the forecast but I didn’t see anything with Kp 6. There are better tools to follow. See below.
What app is the best to forecast northern lights?
I have downloaded ten different northern lights apps and followed multiple websites and the most important thing to say is: it is very difficult to predict the northern lights activity and the apps are often wrong. The long term forecast is very unreliable. Since you know how the northern lights occur you understand this now. It is difficult to predict exactly when the Earth is hit by charged particles. That’s why it is better to follow short term forecasts and ideally live observations. I recommend following:
- Do you speak Swedish? Follow FB page Norrsken. Actually, follow it even if you don’t speak Swedish. The FB translator works pretty well. The page Norrsken makes an amazing analysis every day when there is a chance to see northern lights in Sweden and they also organize observation feeds for all such days. Thanks to that you can see live observations from many followers around the country. It has just reached 100 000 followers so there is a lot of fresh data.
- Follow the Soft Serve News website and its FB page. There you can see the short term forecast and they also notify about upcoming geomagnetic storms (Kp 5 and higher). Besides the Kp number you should also check Bz on their website. To make it simple: it should be negative so you can see great aurora. Another good thing is to check the Ovation map. If the map is yellow or ideally red then there are almost for sure northern lights in Stockholm at the moment.
- Download one of the apps which offers notifications at certain Kp levels. I have for example the app Aurora Pro and I set the Kp notification at 5.
- Download the weather app Windy. It won’t help you with the northern lights forecast, but it will help you plan where to go. If you click on the “cloud” layer you see how the clouds will be moving during evening. Make sure that there are no clouds in the north. Windy is a great weather app in general since you can check multiple weather forecast models there.

Patience is key to see northern lights!
I fell in love with aurora borealis when I moved to Sweden 10 years ago. I was studying at Umeå University and since the city lies pretty far in the north there is often a high chance to see aurora. Hunting northern lights quickly became my favourite hobby. I had a lot of great experiences which I could use later when I moved to Stockholm. Here in Stockholm I have seen many auroras too but two of them stand out: the one which I introduced at the beginning of this article and also in 2017. That time I managed to photograph an amazing panorama at Monteliusvägen.
That day my fiancée and I were waiting for two hours in freezing temperatures. She later decided to give up and went home. Luckily I stayed and after 10 minutes the amazing display began. I quickly called her to come back and she thought I was joking. It took some time to persuade her that it was not a joke. She ran back just in time to witness this beauty.
Remember, this doesn’t always happen. It happened many times that we saw nothing. My success rate to see aurora in Stockholm is only one in four! You have to try, try and try but once you manage you will never forget the moment.
How do I decide if I go northern lights hunting in Stockholm? I check the above mentioned sources daily. It only takes a few minutes and you can see directly if there is a chance that day. If I see a possibility for the upcoming night (meaning the Kp 5 or higher is expected) I prepare my equipment. Besides camera and tripod, we always bring warm clothes, hot drinks and we often barbecue. I often go hunting with my fiancée or with friends. Even if we don’t spot any northern lights that evening we still have a great time! Remember, patience is the most important. The longer you stay outside the higher chance you have to see the northern lights.
What is the best location to see aurora (not only in Stockholm)?
In general, it is important to have a clear view over the northern horizon and to be on a dark spot. I recommend being on the southern shore of a large lake or sea with a great view to the north. In Stockholm Lappis beach is perfect for instance. I also like the Monteliusvägen viewpoint but there is a big problem. There is a lot of light pollution in the city center which makes it more difficult to see auroras. Try to find a spot as dark as possible. The best area nearby Stockholm is the archipelago. Check out the Light Pollution Map.
Book the best northern lights tour in northern Europe or Alaska
Are you living far from the north? Would you like to make sure you will see northern lights on your trip and have also wonderful pictures? Book a northern lights guided tour. The tour operators are experts in their areas and they know where to see northern lights even when weather forecast says it will be cloudy. Here are my recommendations for the best northern lights in northern Europe:
- Sweden: Abisko northern lights tour – Abisko is a small Sámi village nearby Kiruna known for exceptionally good weather compared to the surrounding area because it is hidden by mountains around. Witness aurora borealis here in this magical place with comfortable transport from Kiruna.
- Norway: Tromsö northern lights tour with free photos – Tromsö has a fantastic location for northern lights as you can drive from there to multiple directions including Finland and that’s why it’s easier there to find a clear sky. It can’t be cloudy everywhere!
- Iceland: Small-Group Premium Northern Lights Tour from Reykjavik – If you visit Iceland and plan to make a long trip, you will very likely see northern lights at some point. If you visit Iceland though just for short time and you plan to stay only in the capital Reykjavik, book this trip. It’s organized in just a small group and the guides are real experts.
- Finland: Rovaniemi: Northern Lights Tour with Guaranteed Sightings – Finland is also a paradise for aurora borealis watching. Book this best rated guided tour in the village of Santa Claus Ravaniemi which guarantees sighting of aurora borealis.
- Alaska: Fairbanks: Northern Lights and Chena Hot Springs Tour – If you would like to see northern lights in northern America you will have the biggest chance at Alaska. Most trips are offered from Fairbanks and this tour has best reviews. It also includes a visit of Chena Hot Springs.
Tips for accommodation around the world to see northern lights
As i explained earlier in this article, you will have a higher chance to see northern lights the more north you travel. At the same times, it’s necessary to find a spot without light pollution to see aurora borealis as bright as possible. Therefore, I recommend remote accommodations far from cities. Keep in mind that booking accommodation at these places doesn’t guarantee seeing northern lights. You also need clear sky. I selected for you places where you have pretty high chance but to make it even higher, I recommend to book a guided tour which I recommended earlier.
- Sweden: I will just repeat here that Abisko is the best place to see aurora borealis in Sweden. There is also a very nice accommodation STF Abisko Turiststation where you can experience not only northern lights but also a lot of other activities including sauna or ice climbing. If you are looking for an adventure, you can also spend night at Swedish Ice hotel (warm rooms are offered too) which is also known as a good spot to see aurora borealis.
- Finland: This unique Arctic TreeHouse Hotel in the north of Rovaniemi is beautifully hidden in the nature so you will be far from light pollution. Here you can marvel at northern lights even from the warmth of your room through large windows.
- Iceland: In the land of fire and ice, I strongly recommend to book hotel Ranga to witness aurora borealis. It isn’t far to drive from Reykjavik but far enough to have zero light pollution and thus excellent conditions to watch nights sky.
- Alaska: The best accommodation at Fairbanks to see aurora can be found at Aurora Villa which has a perfect remote location and large windows so you can watch the dancing beauty in the sky from the warmth of your accommodation.
