If you're planning a trip to see the Northern Lights (also known as the Aurora Borealis), timing is essential. In regions like Lapland, the aurora season lasts from mid-August to mid-April, with the first lights often appearing as early as August 8. During the summer months, especially in places like northern Norway, Finland, and Iceland, the midnight sun keeps the sky bright all night long, so it's impossible to see the aurora.
From September to March, the nights are long enough to create the darkness needed for viewing the Northern Lights. In fact, in the far north, you can have up to 24 hours of darkness in the middle of winter.
To address a common question— 'When is the best time to see the Northern Lights?' —the months of September, October, February, March, and early April typically provide the highest chances for sightings. This is primarily due to improved weather conditions and increased auroral activity associated with the equinox.
A month-by-month guide for the best time to see Aurora
Northern Lights in August
The first signs of the Northern Lights can appear around August 8-10 at northern latitudes. However, this is not the ideal time for viewing the Northern Lights.
At the beginning and mid-August, nights are still quite bright, so even during stronger auroras, you might only see a faint glow in the sky. The best time to visit in August is after the 25th when nights start to darken. The weather is usually milder, making it comfortable for evening outings.
Average Temperature: 10°C to 20°C (50°F to 59°F)
Northern Lights in September
September is one of the best months to start aurora hunting. The nights become longer, providing ample darkness for aurora viewing and the equinox effect contributes to stronger and more vibrant aurora displays, making it one of the key reasons for the increased intensity of the lights during this time.
The weather tends to be favorable, with fewer cloudy nights and mild temperatures, making it enjoyable to spend time outdoors (with the lowest temperatures around 0°C). Thanks to the favorable temperatures, the unfrozen lakes provide beautiful reflections of the auroras on the water.
Average Temperature: 5°C to 10°C (41°F to 50°F)
Northern Lights in October
October is also an excellent month for aurora viewing. The equinox effect continues to create spectacular displays throughout the month. October brings cooler temperatures, marking the transition into full winter.
The longer nights provide excellent opportunities for spotting the Northern Lights, and the chances of clear skies are generally high. With autumn foliage still visible in some areas, this month can also offer beautiful backdrops for photography. Be prepared for occasional snowfall, which can add to the scenic beauty but might also bring cloud cover, so keep an eye on the forecast.
Average Temperature: -2°C to 5°C (28°F to 41°F)
Northern Lights in November
In November, days are getting shorter, making it a great time for aurora hunting. However, it can also be one of the cloudier months in many regions, which may obscure the view of the lights.
By this time, snow has usually arrived, creating a stunning winter landscape that enhances the beauty of the Northern Lights. The temperatures can drop significantly, so it’s essential to dress warmly.
Average Temperature: -5°C to -25°C (23°F to -13°F)
Northern Lights in December
December is a magical month for Northern Lights, as the long nights provide ample opportunities for aurora viewing. The snow-covered landscape creates a stunning backdrop, making the auroras appear even more vibrant against the winter scenery. While cloud cover can still be an issue, many areas experience clearer skies, especially towards the end of the month, increasing the chances of witnessing this natural wonder.
Temperatures can be quite cold, so dressing in layers is essential for staying warm while outdoors. Additionally, December brings a festive atmosphere, with holiday lights and activities adding to the charm of winter adventures. Overall, it's a prime time to experience the beauty of the Northern Lights.
Average Temperature: -10°C to -35°C (14°F to -31°F)
Northern Lights in January
January offers some of the best chances to see the Northern Lights, with long, dark nights and typically cold temperatures. The colder weather often leads to clearer skies, which are ideal for viewing. Dress in layers to stay warm while waiting for the lights to appear.
During this month, temperatures can be quite frigid, typically ranging from -10°C to -40°C (14°F to -40°F). It’s crucial to dress in warm, layered clothing to stay comfortable while outside. January truly captures the essence of a winter wonderland, making it a perfect time for an unforgettable aurora adventure.
Average Temperature: -10°C to -40°C (14°F to -40°F)
Northern Lights in February
February continues the trend of long nights and cold temperatures, making it another great month for aurora viewing. As winter progresses, many regions experience a mix of snow and clear skies, which can create stunning landscapes for photography.
The increased daylight towards the end of the month doesn’t detract from your chances, as the auroras are still visible in the evening hours. February is often considered one of the peak months for aurora activity.
Average Temperature: -5°C to -15°C (23°F to 5°F)
Northern Lights in March
March is a transitional month, where nights start to get shorter but remain long enough for good aurora viewing. Around the spring equinox (approximately March 21), auroral activity tends to peak, similar to September.
The weather can vary widely, with the possibility of both clear skies and early spring storms. As temperatures begin to warm, this month can offer a more comfortable viewing experience.
Average Temperature: -5°C to 5°C (23°F to 41°F)
Northern Lights in April
At the start of April, the conditions are often favorable for viewing the Northern Lights, with many clear nights in the first ten days. This period is typically excellent for aurora sightings due to its proximity to the equinox, which still enhances aurora activity.
However, as the month progresses, the nights become significantly shorter. After April 10th, I wouldn’t recommend planning a trip, as the nights not only shorten but also become brighter, making it more challenging to catch a good display when you have only about two hours of darkness.
While the aurora season can extend until April 23rd, spotting the lights during this time requires particularly strong auroras for a successful viewing.
Average Temperature: -5°C and 5°C (23°F to 41°F)
Conclusion
From August to March, each month presents unique opportunities and challenges for viewing the Northern Lights. With varying temperatures and weather conditions, planning your trip around these factors can enhance your chances of witnessing this breathtaking natural phenomenon. To experience the best of the aurora, being informed will help you make the most of your adventure.
