The Northern Lights Are Not What You Think: Here’s How to See Them Better
Nothing quite beats the hypnotic hum of the Northern Lights: Streams of colours spilling across night like liquid silk. The horizon barely holding its shape beneath it. The rest of the world feeling quite, for the lack of a better word, secondary.
Every autumn/winter, like clockwork, the world falls for the Arctic Circle’s quixotic spell – but few are prepared for how little of it actually resembles the certainty implied by the idea of guaranteed sightings.
Even fewer, realise how actively you have to work at it just to tilt the odds in your favour.
The movement, the waiting, the decision-making: the truth is, the Northern Lights sits in that rare category of natural phenomena that has been heavily romanticised to the point of distortion. Online, it is often framed as something you either ‘catch’ at the right time or miss entirely… and it does make for a compelling story – except, that is not quite how the experience actually works.
In reality, seeing the aurora is less about passive moments of luck and more about understanding the layered system of conditions that operate independently of itineraries or ideals; and the better you understand them, the more you shift the balance slightly towards your direction.
Which is why, this post will be all about stripping away the romance of the Northern Lights and focusing instead on what actually matters once you are on the ground: from managing the cold, the journey, and even the technical realities of capturing it when it finally appears; to everything else you can do to weight the environment in your favour.
1. It is excruciatingly cold, so dress for it.
Cold reshapes the Northern Lights experience more than the Northern Lights does – and that is one unpopular truth I will die on the hill for.
In Tromsø, winter temperatures regularly fall below -10°C between December and February. Further inland in places like Abisko or the Finnish Lapland can spiral past -20°C overnight. These are not uncommon temperatures when you are chasing the Northern Lights by the way; and if you do not dress for the occasion, the cold will narrow your attention and change the scale of your entire experience.
Some tour groups – if you are embarking on this adventure with one – provide thermal suits, but do not take this a sign to dress down. Layer as you would a cold winter night; and where possible, always opt for wool over cotton because damp fabric loses insulation rapidly once exposed to wind chills. Also get crampons; your knees will thank you.
If you are self-driving, it is integral that you keep a shovel with you in case your wheel gets caught up in compacted snow. This actually happens more often than you think… and no, stepping on the accelerator does not help. (In fact, it will only sink you in further.)
2. Book tours that will go the distance.
Presuming that you are taking this very seriously, my second piece of advice is to steer clear of tours underscored by heaps of extra-curriculars. Skip the ones that stop at the first clearing twenty minutes outside the city, or are more interested in getting dinner and setting up hot chocolate for everyone. Also definitely resist the urge to just hop on board the cheapest / most activity-filled one.
Further, you’d ideally also want a tour that tells you to bring your passport along, because you want them to traverse borders if it really comes down to that. In places like Tromsø, there are aurora operators who effectively become border runners in winter; because guides will drive inland towards Finland whenever clearer skies are statistically more available on the other side. This is something that I can definitely attest to, because my own tour from Tromsø drove a brutal 2.5 hours into Finland before we finally broke through the cloud cover.
All this, of course, is predicated on the notion that the Northern Lights are the one single variable that you want your entire night to be structured around.
Conversely, there are also plenty of tours who will be quick to package the full Arctic immersion and fold in dinner stops or reindeer rides and husky sleds as part of the adventure – and inherently, there is nothing wrong with that. But it does serve a different intention and you need to ask yourself if the Northern Lights are something you don’t mind catching between experiences, or something you want to lock in on come hell or highwater.
If the priority is the latter, then understand that every additional layer of programming for the night becomes a form of interruption, and every detour narrows the window in which you can respond to shifting forecasts.
This isn’t to suggest that multi-activity tours are not legitimate; I am pretty sure on a good night, you can see the aurora while making time for a cultural dinner and hot chocolate and a husky or reindeer ride or two.
The difference only really matters when the sky chooses not to cooperate. And on those nights, do you want the operator that anchors your experience around a fixed set of activities… or the one that will strategise distance and push through every variable before accepting that it is not going to happen?
Both outcomes are valid in what they deliver. But, they are not interchangeable in what they optimise for.
3. If you are self-driving, be very, very careful.
What do you know about driving in winter conditions?
If you answer is “it can’t be that different”, you may want to be a little more deliberate moving forward.
Fact is, winter driving isn’t right for everyone. Throw in night conditions, unfamiliar roads, and the pressure of tracking forecasts and a hundred different apps while you are on the move, and the margin for error narrows even further.
This is not to say that you shouldn’t do it. But it does mean that you need to be honest about what you are combining in a single moment (low-visibility driving, shifting weather systems, and the constant pull of chasing something that is, by nature, unpredictable); and you need to make sure that you are more than prepared for the road to stay the priority, even when the sky is the reason you are there.
I have written more extensively about driving in winter conditions in a separate piece, and it’s a good baseline read to jumpstart your research into the specifics. Know the tools you need; stock the equipment that matters; and most importantly, commit to memory the emergency numbers you need – including that of your accommodation/host – before you set off.
4. And whether you’re doing it on tour or independently, schedule your chase early.
Not early in the sense of time of day; but early as in, do it on the first or second night of your itinerary such that if you really do miss it (and it is not uncommon to), you still have space to rebook and try again under better conditions (some tour providers even practise a free or discounted rebooking if the first one doesn’t pan out).
If you leave the Northern Lights towards the end of your trip, you lose that flexibility almost immediately, especially in peak months when availability is tighter and not every tour will have spare seats to offer at a moment’s notice.
5. There is a lot of waiting involved. Like, a lot.
I think people underestimate this because most images of the Northern Lights compress the experience into a single decisive moment; but know that any Lights worth its salt usually involves a whole ton of down time in between.
Most tours leave around 6–7pm in the evening and only return after 1–2am – sometimes even closer to 3am depending on how far you traversed – and in between, there are hours of long drives, standing by in partial darkness beside an idling vehicle, watching the same stretch of sky for movement that may or may not arrive.
And the cold.
I have been on five Northern Lights chases in my life, and every single one of them has involved prolonged confrontation with the cold (which I have a strong aversion to) and ended in some form of exhaustion at the end of the night (on all five occasions, I slept the entire drive back). I assert, categorically, that much of the Northern Lights experience is more of a test of patience rather than spectacle; and I say this because in order to actually enjoy it, you need to go in with the right expectations before you get there.
Perhaps more importantly, this is something worth thinking about very carefully if you are contemplating bringing young children along. Not every child is going to respond well to seven or eight hours of intermittent waiting in sub-zero temperatures, especially when the ‘reward’ is unpredictable and often delayed. And because most aurora tours operate in shared groups, one exhausted or frustrated child can very quickly shift the atmosphere for everyone else in the vehicle too.
I have, unfortunately, seen my own fair share of kids* cry, sulk, whine, refuse to budge (especially after making a couple of unsuccessful stops along the way); so even if you think your kid is old enough, maybe sit them down properly beforehand and walk them through what the night is actually going to look like so that they are not blindsided by how much “nothing” is about to ensue. A moody, surly teen everyone can accept; but a cold, overtired, overstimulated crying child? In this context, it is definitely not on the kid, and all eyes on the bus will know that.

6. KP Index is useful… but not a promise.
When it comes to indicators and forecasting conditions, the KP Index is only half the adventure.
The KP Index measures geomagnetic activity (or disturbances, if you will) in the Earth’s magnetic field; and is, in a nutshell, helpful for general forecasting because it tells you whether aurora activity is likely to be strong or weak on a given night. But what it cannot tell you, is whether the sky is actually going to be clear. Once the clouds are thick, the KP index immediately becomes secondary information; because, let’s put it this way: if the mountains are crumbling and I place blinders on you, do you actually see the mountains crumbling?
And if we were to build on that: if a geomagnetic storm is unfolding but the clouds cover it completely, will you see the Lights dancing?
That’s right. Like the crumbling mountains, you can expect to see nothing.
When it comes to the probability of the Northern Lights, a clear sky trumps all else, and this is something that many fail to grasp when they rely too much on the KP Index without factoring in the skies. You could have a high KP Index and still be staring at a flat grey ceiling for hours, if it coincides with a completely overcast sky. Be wary of guides who rely exclusively on the KP Index and nothing else – although, in all likelihood, most will know better and trust sky conditions more than apps.
If ill luck sticks you with a novice guide, nudge them towards open patches of sky where necessary and possible, especially if the deal isn’t to stick near the city. And of course, if you are doing this independently, then remind yourself the same and prioritise sky conditions as much as you do the KP Index.
7. It is not as colourful as you think.
Sometimes, it is not even as green as you think.
Cameras do not translate the experience so much as reconstruct it; because long exposure accumulates light over time in a way the human eye simply does not. Take for instance, this photo below. What do you think my eye saw in that moment?
Hundred points if you said, “nothing”.
This is not to say, of course, that you will be shelling hundreds of dollars to look at a washed out sky. When solar activity is strong enough and conditions align, you will absolutely see an eruption of vivid, unmistakable colour that will make even the snootiest, most discerning photographer blush with envy – but that intensity is not constant, and it is not guaranteed. Most of the time, your experience will begin with a pale green smear – and if you are lucky, this slowly deepens to glowing bands of greens, rippling, widening, spilling into arcs that stretch past treelines.
And on that note, you may also want to manage your expectations about the variety of colours you will get to see: green is the most common because it comes from a collision with oxygen (which the upper atmosphere has an abundance of); and on low to moderate nights, it will be what is easily delivered.
For purples and pinks to appear however, activity needs to penetrate deeper into the atmosphere and collide with nitrogen alongside oxygen – and this requires plenty more energy; which is why people often associate these two colours with “stronger” nights.
Simply put, you need a hell lot more activity for that.
8. Cameras: What you really need for a good photo…
To dovetail with my previous point: cameras.
If photos are important for you and you want the kind of photos you see online, ditch the notion that a phone camera will get you there.
You will need a DSLR (most will do a good job). You will need a tripod. And you will also need a remote control (an intervalometer works too). Even with a flash (which is helpful but not mandatory), you are looking at a minimum shutter speed of 0.5-2 seconds*; and with that amount of time, even the steadiest hands will unwittingly produce motion blur. Unless that is the intended style, a remote shutter (and tripod) is required to eliminate any and all movement.
Also, everyone has their own sweet spot when it comes to settings; so don’t fret over which is more “correct” because chances are, all of them are. It really depends on which suits you and your camera best; and in case more noise to the conversation helps, these are mine:
* SHUTTER SPEED | Without a flash, I’d recommend these shutter speeds instead:
Insanely strong aurora: 0.5–2 seconds | Strong aurora: 1.5–5 seconds | Moderate aurora: 5–10 seconds | Faint aurora: 10–25 seconds
FOCUS | Manual Focus only, and it should be set to Infinity. If your lens does not have that option, focus on a star.
ISO | My recommended sweet spot is between 1600-3200, but take this as a gauge, not a rule.
APERTURE | just go as wide as possible. You’re basically using this to balance out your ISO and reduce noice as much as you can help it.
Also, pack more batteries than you think you’d need. The science is true: the cold zaps out batteries faster than you would imagine.
9. … and what you really need for a good video
Speak about the bane of my existence.
There is nothing that evaporates your confidence in your own gear like attempting to make a video of the Northern Lights. I mean, you think you have a decent set-up; you even manage to catch a few money shots. And then you switch over to video with the presumptuous sense that it will all carry over… only for everything to just suddenly fall apart and dissolve into one colossal failure of an opaque rectangle filled with black nothingness.
The truth is, a decent aurora video requires even higher specs than a photo. You will need even stronger high-ISO performance, a newer full-frame sensor, and modern processing pipelines that can truly hold detail in near-darkness without everything collapsing into noise. This means that even a decent DSLR will most likely fall short of capturing anything that one can reasonably call usable footage; and newer iPhones, while surprisingly capable of producing something more than darkness, will still hit a ceiling when it comes to noise.
Expect decent aurora video to become realistic only once you move into the likes of Sony A7 III, Canon R6, Nikon Z6/Z8, and up. All this, of course, is only if you are hankering after the kind of cinematic footage people often imagine. If you are unfussy, I believe even an iPhone 13 will suffice – although, I do have to reiterate that ‘suffice’ here essentially means filming something remotely aurora-shaped, and nothing more.
10. The Northern Lights are not going to disappear
What’s all that clickbait again about 2026 being the last year to see the Northern Lights?
Scientifically speaking, there is a real basis behind what people are referring to – but, it has very little to do with the aurora ‘ending’, or ‘disappearing’, or becoming impossible to see again until some random faraway year in the future.
What is actually happening, is that we are shifting into a quieter phase (the Solar Minimum*) that makes spectacular geomagnetic storms less frequent and, in turn, less visible; but solar flares will still occur unpredictably during this time (the Northern Lights are, after all, notoriously fickle). On nights when activity is strong enough, those Lights from a ‘quiet year’ will punch well above its weight and outperform even an average night from a ‘peak year’. Just make sure that you are at the right place (preferably anywhere in the Arctic Circle) at the right time (closer to winter), and really play your cards right (re: Points 2, 4, and 6); and you’ll probably have just as good a shot as any to be delivered a knockout in all the ways that actually matter.
* The Northern Lights are driven by solar activity, which follows an approximately 11-year cycle. During this cycle, the Sun moves between periods of higher and lower activity, and when the Sun is more active >> it releases more charged particles into space >> and these particles interact with Earth’s magnetic field and upper atmosphere >> thereby producing what we know as the Northern Lights.
