Best time to see the Northern Lights

At 50 Degrees North, one of the questions we hear most often is when to come for the Northern Lights. The honest answer is that the Nordic region gives you a long window to work with, which takes some of the pressure off the timing.

The aurora is at its most frequent between the autumn and spring equinoxes, roughly late September to late March, when the nights are long and dark enough for the lights to show. There is a quiet bonus here too: geomagnetic activity tends to run a little higher around both equinoxes, so the weeks either side of late September and late March can be particularly rewarding.

To actually see the lights, you need darkness and a clear sky. Cold weather is not strictly required, but clear skies in the Arctic usually arrive with cold air, so the two tend to come together. There are several free aurora forecast websites and apps that show the likelihood of activity night by night, and they are worth checking once you are on the ground.

October and November can be stormy, especially along the coast, but they are generally good months. From December the weather tends to dry out and snow settles across the landscape, the white Christmas and winter wonderland most people picture. The snow also opens up the chance to pair your aurora hunting with daytime adventure: dog sledding, skiing, and reindeer sledding among them. Worth knowing that in the darkest weeks, from December into early January, daylight is limited to a few hours, with long, drawn-out dawns and dusks. For aurora viewing that is no bad thing, but it is good to plan your days around it.

How the solar cycle affects the Northern Lights

The sun runs on an 11-year rhythm of rising and falling activity, and the aurora rises and falls with it. Solar Cycle 25 peaked in late 2024 to early 2025, exceeding the original forecast, and activity remains elevated through 2026 and into 2027 before gradually declining toward solar minimum around 2030 to 2031. In plain terms, the next couple of seasons sit in a genuinely strong stretch of the cycle. Activity stays elevated for roughly two to three years around the peak, so 2026 should still be an active year, particularly in its first half, with 2027 to 2028 somewhat quieter.

We would gently caution against treating any single year as a now-or-never moment, which is how some of the coverage frames it. This far north, even in quieter years, the aurora is a frequent sight through the season, often appearing high overhead. The solar cycle improves your odds; it does not make or break the trip.

Can you see the northern lights during a full moon?

If the aurora is very weak and sitting directly in front of a full moon, the moonlight can wash it out. But in our experience, any half-decent display is clearly visible even under a full moon. We would not plan a trip around lunar phases.

A fair word of caution: the Northern Lights cannot be guaranteed on any given night. Some of our guests have watched several strong displays unfold over a few hours, while the following week, with conditions shifting only slightly, the lights stay hidden. Patience helps, and so does remembering to look north when you are out searching. Our Northern Lights journeys are designed by people who live in the region, with routing and timing built to give you the best chance of seeing the aurora.

Where to see the Northern Lights

Matching the right time of year with the right place is part of how we build every journey. Several of our destinations sit well inside the auroral zone, high above the Arctic Circle: Norway's Svalbard, along with Greenland, Iceland, and Norwegian, Finnish, and Swedish Lapland.

The shape of the trip is yours to decide. An active adventure, or a city-based stay with the lights as a backdrop? A night in the ICEHOTEL, or a glass of something on the deck at Lyngen Lodge? The people who live here have made an art of a long winter: hot tubs on the porch, glass igloos angled at the sky, and quiet, warm lodges, the kind of details that tend to stay with you.
