While the northern lights, or aurora borealis, do look otherworldly, there’s a scientific explanation for this breathtaking natural phenomenon.

It all starts with solar storms around the sun that send blasts of electrically charged particles towards Earth. When they collide with the upper atmosphere, they produce glowing emissions. If a lot of these reactions take place at the same time, it causes a jaw-dropping light show that you can see in the sky.

The movement, shapes and colours you’ll witness depend on the type of atoms involved. Other factors include the intensity of solar activity and the pull of Earth’s magnetic forces.

For instance, green is often the most common colour you’ll notice during an aurora event. But if the levels of solar activity are high, you might also catch flashes of blue, purple and red.

Delve deeper into what causes the northern lights.

Absolutely! Visit Iceland in winter – October to March – and you’ll discover it’s an excellent place to go if you want to hunt for the aurora.

This is because you’ll need darkness if you’re to see the northern lights, making Iceland’s long winter nights ideal. Low light pollution, high solar activity and cloudless skies are the other key things you’ll need to come together. Happily, you can also experience these in Iceland.

You’ll also find that the country has large unpopulated regions where there’s little or no light pollution – perfect for chasing the aurora. Plus, as it lies within the “northern lights belt” (or “aurora zone”) there’s lots of solar activity in the skies above Iceland.

Just wait for a night with clear skies, keep an eye on your aurora forecast app, and you could glimpse the northern lights. Uncover top tips and more in this guide to the aurora in Iceland.

The winter months of October to March are the best time for you to see the northern lights in Iceland. This is because, across the Northern Hemisphere, the nights are long and dark at this time of year.

In fact, during mid-winter – December and early January – the days can be so short that you’ll have around 19 hours of darkness. And the longer the nights, the more chances you’ll have to spot the aurora.

There are plenty of reasons to visit Iceland in summer, but don’t travel in May, June, July or August if you want to see the aurora. This is because you need dark skies to see the northern lights. And during summertime, the nights are not dark or long enough to see them.

Instead, you’ll want to visit between October and March – the Icelandic winter – when your chances of seeing the lights are much better. It’s also possible to glimpse the aurora in early spring (April) and autumn (September).

Thanks to winter’s long nights, you can see the northern lights all over Iceland at this time of year.

What’s more, the country sits within a zone called the “northern lights belt”, a band encircling the globe at latitudes of 65-72°N. With the most frequent and intense levels of solar activity, this region is the best place to go to if you want to see the aurora.

Remember, for the brightest and clearest displays, head away from any nearby light pollution. By venturing into the countryside, where it’s darker, you’ll get to enjoy this natural spectacle at its most vibrant.

The aurora borealis can happen at any time throughout the year. But over the spring and autumn equinoxes, you’ll find that solar activity ramps up. This means displays of the aurora could occur more frequently around these dates in March and September respectively.

Compared to the middle of winter, the nights are shorter over the equinoxes. So although the northern lights might not be dancing quite as much in winter, you’ll have a better chance of seeing them during these darker months.

Along with the solar activity that causes the aurora, you’ll need a few other key factors to come together at the same time. These are clear skies, darkness and low levels of light pollution.

One of the most convenient ways to keep an eye on the levels of solar activity is to download an aurora app to your smartphone. Combine this with a local weather forecast, and you’ll get a good idea of when you might be able to see the northern lights. So keep a look out for when a cloudless night and high solar activity match up.

It’s worth bearing in mind that even if you do have the right conditions for the northern lights, they may not appear when you want them to.

The best way to see the northern lights depends on how you want to experience Iceland. Not to mention the other things you’d like to see and do while you’re here.

With Nordic Visitor, you can choose the travel style that works for your northern lights getaway. Take your pick from self-drive, small group and privately guided tour packages, along with stays in Reykjavík that include guided excursions.

To embrace the freedom of going at your own pace while chasing the northern lights, choose a winter self-drive tour in Iceland. Your package will include accommodation, a rental car, daily breakfast and more. You’ll also benefit from the insider know-how of your dedicated travel consultant who’ll make all the arrangements for you.

They’ll give you a detailed itinerary and hand-marked map, complete with recommendations on where to stop along the way. And with a car, you can make spontaneous stops on your trip. So if the aurora appears unexpectedly, you can hop into your car and pick a good viewing spot.

But if you’d rather leave the winter driving to someone else, opt for a small group tour of Iceland. This way, a professional guide will show you the country’s iconic spots and hidden gems, and share their local knowledge with you. On winter tours, they’ll also be keeping an eye on when the northern lights might appear.

If you’d like to be accompanied by a driver-guide while having the freedom to customise your trip, pick a privately guided tour. This option gives you the flexibility of an independent trip while benefitting from the expertise of a local guide.

Plus, if you have specific interests, we’ll select a guide to match. Not to mention you’ll be able to choose your travel companions – perfect for a break with friends or family.

On the other hand, multi-day tours are ideal if you’d like to stay in one location during your time in Iceland. Most of these packages are based in the bustling capital of Reykjavík.

As well as accommodation, your trip comes with handpicked excursions into the stunning countryside. This lets you discover top spots such as the Blue Lagoon and Golden Circle without needing to unpack and repack your bags.

Seeing the aurora with your own eyes is a spellbinding experience you’ll never forget! But capturing the lights on camera can be tricky if you don’t take some time to get to know your camera’s settings.

An SLR camera with manual focus works well. And it helps to have a tripod to avoid blurry images. Here are some top tips for getting the best shots of the northern lights:

• Shutter release: For even steadier shots, get a remote shutter release so you don’t have to touch the camera at all when taking a picture.
• Spare batteries: Cold temperatures tend to deplete the life of your battery levels faster, so make sure to bring 1 or 2 spares.
• Head torch: This will be essential to let you see what you’re doing when you’re shooting in the dark.
• Image stabilisation: If your camera has this, turn it off.
• ISO: To increase your camera’s sensitivity to light, set the ISO to around 400, 800, or higher if possible.
• Aperture (f-stop): Set your aperture as low as possible. This will result in more light coming through the lens. On most cameras, you’ll find you can get this down to about 3.5.
• Shutter speed: Use a long exposure of 15 to 30 seconds. The longer the exposure, the more light your camera will capture.

All of these northern lights packages have been curated by Iceland-based experts to ensure you’ll have an unforgettable trip. But it’s also possible to personalise your tour by extending your stay or adding optional activities to your itinerary.

In fact, it’s easy to tailor your trip when you book online. You can choose from extra night options and additional excursions. For instance, you could chase the northern lights by boat or super jeep. Or why not try activities such as relaxing in the Sky Lagoon, snowmobiling on a glacier, and exploring ice caves?

For the ultimate tailored travel experience, opt for a privately guided tour of Iceland. Not only will your dedicated travel consultant customise your itinerary to your needs, but you’ll also get a guide with similar interests.

If there’s something specific you want to do during your trip, just ask your travel consultant – they’ll have the inside scoop.
