The best time to see the Northern Lights in Rovaniemi is from late September to early April, with the peak season being from December to February. During these months, the long polar nights provide extended hours of darkness, maximizing the chances of witnessing this spectacular phenomenon. The lights are visible on clear nights, with no interference from the midnight sun, which does not occur in winter.
An interesting thing about seeing the Rovaniemi Northern Lights in the year 2025 is that this frequent occurrence is likely to return only after 11 years. This year will see solar activity at its peak as there will be an increase in solar flares and coronal mass ejections. With a higher frequency of solar storms, the lights are expected to be even more vibrant and visible, making this a prime year for witnessing the auroras. So, don’t miss out!
Long polar nights occur in the Arctic and Antarctic regions, when the sun remains below the horizon for weeks or even months, depending on the latitude. This phenomenon takes place during the winter, particularly above the Arctic Circle, where Rovaniemi is located. Here, the sun sets around the autumn equinox and doesn’t rise again until the spring equinox. The further north you go, the longer the darkness lasts. Furthermore, let us try to understand the connection between these polar nights and the Northern Lights.
During the long polar night, the sky remains dark for weeks or even months, creating ideal conditions for viewing the Northern Lights. Without daylight to outshine them, auroras are more visible, especially in regions like Norway, Sweden, Finland, and parts of Canada and Alaska, particularly during the darkest winter months when light pollution is minimal.
While auroras can occur year-round due to solar activity, the extended darkness of polar nights allows for longer viewing windows. As Earth's magnetic field directs solar particles toward the poles, auroral displays are often most intense in the Arctic and Antarctic regions, where polar nights are most pronounced.
Though the Northern Lights can be seen throughout the year, their frequency and intensity often peak during periods of high solar activity. The long winter nights provide extended viewing opportunities, sometimes allowing auroras to be visible from sunset to sunrise.
Checking into a glass-roofed cabin is one of the most unique ways to see the lights. You can also find places that have heated domes so you can enjoy the dancing lights from the comfort of your bed.
Of the many ways to see the Northern Lights, a guided tour, a snowmobile ride, or husky sledding are among the top ways to explore the Laplands, each offering a unique experience.
The polar night period, from late November to mid-January, is the ideal time to visit Rovaniemi to view the Northern Lights as it brings 24 hours of darkness, offering extended chances to witness the Northern Lights at any time of day or night.
No, there is no guarantee of seeing the Northern Lights every night, even during the peak season. However, the frequency of seeing them is higher as compared to other times of the year.
Due to the extended darkness during polar nights, it's possible to catch the Northern Lights in Tromso during the day, particularly in December and January, when the nights are longer.
