Whether you are a seasoned traveller or a first-time adventurer, learn how to chase the lights and create unforgettable memories under the celestial display.

The Northern Lights, or aurora borealis, are one of nature’s most breathtaking spectacles, captivating travellers and skywatchers alike. This cinematic display of colourful lights in the night sky is not just a visual feast but also a fascinating phenomenon rooted in solar activity and Earth’s magnetic field.

Northern vs Southern Lights
Don’t get this confused with the Southern Lights! Known as the aurora australis, the Southern Lights in the southern hemisphere, are viewed in countries such as Australia, New Zealand, Antarctica and some parts of South America. Northern Lights tend to be green and white with blue hues, while Southern Lights are generally green and pink with red and purple hues.

How it happens
The Northern Lights are a natural light display predominantly seen in high-latitude regions around the Arctic. The phenomenon occurs when charged particles from the sun collide with gases in Earth’s atmosphere, creating vibrant colours that dance across the sky. This interaction is primarily driven by solar wind, a stream of charged particles released from the sun’s corona.

When these solar particles reach Earth, they are deflected by the planet’s magnetic field. As they travel along the magnetic field lines toward the polar regions, they collide with atmospheric gases, such as oxygen and nitrogen. These collisions excite the gases, causing them to emit light in various colours. The most common colours observed in the aurora are green, red, and purple, each produced by different gases at varying altitudes. For instance, green is typically produced by oxygen at lower altitudes, while red can occur at higher altitudes due to oxygen and nitrogen interactions.

Where to see it
The Northern Lights are most commonly visible in the ‘auroral zone’, which is an area of approximately 2,500 kilometres around the North Pole. This zone includes parts of several countries, making it a prime destination for aurora chasers.

1. Tromsø, Norway: Known as the ‘Gateway to the Arctic’, Tromsø offers excellent aurora viewing opportunities, along with a vibrant cultural scene and various winter activities.
2. Fairbanks, Alaska: This city is situated directly under the auroral oval, making it one of the best places in the United States to witness the Northern Lights.
3. Yellowknife, Canada: Located in the Northwest Territories, Yellowknife is renowned for its clear skies and frequent auroral displays, particularly during the winter months.
4. Abisko National Park, Sweden: This park is famous for its microclimate, which provides clear skies ideal for aurora viewing, along with stunning natural scenery.
5. Rovaniemi, Finland: As the official hometown of Santa Claus, Rovaniemi offers unique experiences alongside the chance to see the Northern Lights.
6. Iceland: With its dramatic landscapes and geothermal activity, Iceland is a popular destination for aurora seekers, especially in areas away from city lights.

While these locations are within the auroral zone, the Northern Lights can sometimes be seen further south during periods of heightened solar activity. However, for the best chances, it’s advisable to stay within or near the auroral zone.

When to see it
When is the best time to see the Northern Lights? The Northern Lights can be seen year-round, but the best time to view them is between September and April. During these months, the nights are longer and darker, providing optimal conditions for aurora viewing. The peak period for aurora activity typically occurs around the equinoxes in March and September, although sightings can happen any night when conditions are right.

The best hours to observe the Northern Lights are generally between 9pm and 3am, with the most intense displays often occurring around midnight. Local weather conditions also play a crucial role; clear skies are essential for visibility, so checking weather forecasts is recommended before heading out.

How to see it
Planning a trip to see the Northern Lights involves several considerations, from choosing the destination to timing the visit.

• Select a location within the auroral zone that suits your travel preferences.
• Consider factors like accessibility, available activities, and local accommodations.
• Popular destinations for aurora viewing can fill up quickly, especially during peak season.
• Book accommodations and tours in advance to secure your place to stay and access to guided experiences.

Many tour operators offer Northern Lights excursions, providing transportation to optimal viewing locations and expert guidance. These tours can enhance the experience, particularly if you are unfamiliar with the area. Winter temperatures in auroral regions can be extremely cold, so it’s crucial to dress in layers and wear insulated clothing. Don’t forget essentials like hats, gloves, and thermal socks.

As the Northern Lights are a natural phenomenon, sightings are not guaranteed. Be prepared to wait and stay flexible with plans, as conditions can change rapidly. If you want to photograph the Northern Lights, bring a camera with manual settings and a tripod. Long exposure times are often necessary to capture the vibrant colours and movement of the aurora. While seeing the Northern Lights is a highlight, take time to enjoy the surrounding landscapes and local culture. Engage in winter activities like dog sledging, snowshoeing, or visiting local museums to enrich the trip.

A must-see dazzling display
The Northern Lights are a mesmerising natural phenomenon that draws travellers from around the globe. Understanding what causes the aurora borealis, where to see it, and how to plan the trip can help you create an unforgettable experience. Whether you find yourself in the snowy landscapes of Norway, the rugged terrain of Alaska, or the enchanting scenery of Iceland, witnessing the Northern Lights is sure to be a highlight of your travels. So pack the bag, grab a camera, and prepare for a magical journey beneath the dancing lights of the aurora borealis.
