Northern Lights or Aurora
The northern lights, or aurora borealis, transform the night sky above Earth’s polar regions into an extraordinary canvas of shifting colours and shapes. These breathtaking illuminations have inspired adventure, science, art, and legend across generations. Whether you seek to understand their origins or plan your own northern lights adventure, this guide provides every essential detail for travellers, photographers, and dreamers.
What Are the Northern Lights (Aurora Borealis)?
The northern lights are natural light displays visible in the high-latitude Arctic and sub-Arctic regions. Waves of green, purple, red, and blue flicker and dance across the horizon, captivating all who witness them. The phenomenon is known as aurora borealis in the northern hemisphere and aurora australis in the south, reflecting the same solar processes.
How the Northern Lights Form
The science behind the aurora borealis starts at the sun. Powerful solar storms eject charged particles into space. When these particles reach Earth, they travel along magnetic field lines toward the polar regions. Upon entering the upper atmosphere, they interact with gases—most notably oxygen and nitrogen—to produce vivid displays of colored light.
Scientific Explanation of Auroral Colours
Auroras appear in a range of colours depending on which gases are energized and at what altitude. Oxygen emits green—by far the most common colour—while high-altitude oxygen creates red hues. Collisions with nitrogen atoms can result in blue or purple auroras. The distinctive patterns and movement, called “auroral arcs” and “curtains,” reflect magnetic forces shaping the particles’ journey.
Where and When to See the Northern Lights
Witnessing the northern lights in person is a bucket-list experience. Proper location and timing dramatically increase your chances of success.
Best Places to See the Northern Lights
-
Yukon, Northwest Territories, and Nunavut in Canada
-
Alaska, especially Fairbanks and the Arctic Circle
-
Tromsø and far northern Norway
-
Swedish and Finnish Lapland
-
Iceland’s wild landscapes
-
Northern Scotland, Siberia, and Greenland
These destinations, known as “auroral zones,” are ideal thanks to their proximity to the magnetic poles, clear night skies, and minimal light pollution.
Seasonality: When Are They Most Visible?
The best time to see the northern lights falls between late August and mid-April, with peak months from September to March. Winter brings long, dark nights and the highest chance of auroral activity. In the Arctic, darkness can last nearly 24 hours, creating a dramatic stage for nature’s light show.
Weather and Light Pollution Factors
Avoiding clouds and city lights is essential. Cold, crisp evenings offer better stability and visibility. The darkest hours, around midnight, maximize contrast between the aurora and the surrounding sky. Full moon nights can still be productive—moonlight illuminates snowy foregrounds, enhancing photographs.
Indigenous Legends and Folklore of the Aurora
The northern lights are steeped in indigenous lore and modern cultural stories.
Ancient Myths and Interpretations
Indigenous peoples of the Arctic, such as the Inuit, Sámi, and Finns, have legends linking the northern lights to ancestral spirits, animal guardians, and messages from beyond. Finnish folklore calls them “revontulet”—fox fires—imagining magical arctic foxes creating sparks with their tails.
Modern Cultural Significance
Today, the aurora borealis is celebrated as a symbol of northern culture and natural wonder. Festivals, stories, and artistic depictions continue to honor its presence, connecting local communities and visitors with the world’s great mysteries.
How to Plan a Northern Lights Adventure
Planning a trip to witness the aurora borealis is both exciting and demanding.
Choosing Your Destination
Start by selecting a prime auroral zone in Canada, Alaska, Scandinavia, Iceland, or northern Russia. Consider accessibility, weather trends, and available accommodations.
Booking Aurora Borealis Tours
Tour operators offer guided aurora hunts, maximizing success with expertise, forecasting, and transport to remote locations. Many luxury packages feature glass igloos, heated sleds, and gourmet northern cuisine—all under the starry sky.
What to Pack for an Aurora Viewing Trip
-
Layered thermal clothing: base layer, fleece, insulated coat, waterproof shell
-
Gloves, hat, scarf, and snow boots
-
Camera with manual controls, tripod, and remote shutter
-
Portable batteries and power banks (cold drains charge quickly)
-
Snacks, a thermos, hand warmers, and a headlamp
-
Adventure spirit and patience
Prepare for long hours outside, waiting for the lights to appear. The aurora is as unpredictable as it is beautiful—serendipity is part of the allure.
How to Forecast and Track Aurora Borealis
Technology now helps travellers predict, track, and optimize their chances of seeing a great aurora show.
Understanding the KP Index
The KP index is a global geomagnetic scale running from 0 to 9. A KP of 4 or higher often means auroras are visible in northern Canada or Alaska. Aurora forecast apps update real-time KP readings, alerting users to high activity.
Best Apps and Online Tools for Aurora Tracking
Popular tools include:
-
Space weather forecast apps
-
Real-time satellite data
-
Ovation maps visualizing aurora probability
Social media groups and local guides also share tips on when and where to go for last-minute auroral events.
Local Forecasting Tips
Experience teaches that clear skies, low humidity, and frigid temperatures correlate with the best viewing nights. Follow local advice and be ready to adjust plans—mobility, flexibility, and preparation pay off in the world of aurora hunting.
Photography Tips for Capturing the Northern Lights
Photographing the northern lights requires skill, patience, and the right combination of equipment and technique.
Essential Gear for Aurora Photography
-
DSLR or mirrorless camera with manual mode
-
Wide-angle lens, preferably f/2.8 or wider
-
Sturdy tripod, remote shutter release
-
Extra batteries and memory cards
-
Headlamp with red light mode (preserves night vision)
Camera Settings for Night Sky Shots
-
ISO 800 to 3200 (depending on ambient light)
-
Aperture f/2.8–f/4
-
Exposure time 5–30 seconds
-
Manual focus set to infinity
Experiment with composition, foreground interest, and changing exposure. Bracket shots to capture varied brightness and colour detail.
Composition, Framing, and Creative Techniques
Include landscapes, trees, cabins, or silhouettes for scale and depth. Moonlit snow or frozen lakes can provide a dramatic contrast. Capture wide panoramas and close-up arcs; center compositions on strong auroral features.
Don’t forget to tag your photos with alt text packed full of SEO keywords, such as: “green northern lights above snowy forest,” “best camera settings for aurora,” and “aurora borealis photography tips.”
Fun Facts About the Northern Lights

Indigenous-Led and Community-Based Experiences
Many northern communities offer indigenous-led tours, blending aurora viewing with storytelling, traditional foods, and educational activities. These trips foster cross-cultural understanding and sustainable travel.
Frequently Asked Questions About the Northern Lights
Why Are the Northern Lights Green?
Green is the most common colour due to oxygen atoms at lower altitudes, which release photons in green wavelengths during particle collisions.
Can You See the Aurora in Summer?
No—the Arctic’s “midnight sun” keeps the sky too bright for auroral visibility. True aurora season begins when the nights are long and dark.
How Long Do the Lights Last Each Night?
Auroras can last from a few fleeting minutes to several hours, changing form, colour, and intensity as solar activity and atmospheric conditions shift.
