Northern Lights in Trondheim
Trondheim lies at 63.4°N where the Nidelva river runs into the Trondheimsfjord, far enough north in Norway that the aurora turns up several times a season. It does not take a storm: moderate activity, well short of a G1 minor storm on the NOAA scale, is often enough for a glow in the north from the hills and shores outside the center, and a more active night can bring it over the city itself. Most of the time it is an arc low in the north, so what counts is getting above or away from the city’s lights with an open view over the fjord.
Adresseavisen covers these nights regularly, with readers’ photos from the shores of the Trondheimsfjord and from places such as Saksvik in Malvik, just east of the city. Phone cameras in night mode pick up color the eye does not, so a sky that looks gray to you can come out green and pink. See how to photograph the aurora with an iPhone.
Gråkallen’s radar dome and the Bymarka forest
Gråkallen, 552 m, rises out of the Bymarka forest about 7 km west of the center, with the city lights below it. From the car park and bus stop at Skistua it is a 1.5 km walk to the top, open all year, and the round radar dome on the summit is visible from the city. Lower down, the Gråkallen Line tram from St. Olavs gate climbs to Lian, 234 m up at the edge of the same forest.
Looking north over the fjord from Lade and Trolla
- Korsvika, a beach on the Lade peninsula about 4 km north-east of the center, on the Ladestien coastal path, looking north over the fjord. Ladekaia, further along the path, is used too.
- Trolla, about 6 km west of the center on the shore, with the same view north over the water.
Closer in, Kristiansten Fortress is a walk from downtown, but the city glow means it only works on strong nights.
FAQ
How often can you see the northern lights in Trondheim?
Several times in a typical season, usually as a glow or arc low in the north. At 63.4°N Trondheim does not need a big storm, but the city lights hide weaker displays, so the usual places are Bymarka above the city or the shore at Lade or Trolla, looking north over the Trondheimsfjord. On strong nights it can be seen over the center.
Where can you see the northern lights in Trondheim without a car?
The bus to Skistua drops you at the foot of Gråkallen, 552 m, a walk of about 1.5 km to the top. The Gråkallen Line tram runs from St. Olavs gate up to Lian, 234 m, at the edge of Bymarka. For a sea-level view north over the fjord, take the bus out to Lade and walk the Ladestien path to Korsvika beach, about 4 km from the center. Kristiansten Fortress is walkable from downtown but only works on strong nights.
Are the northern lights more common in Trondheim than in Oslo?
Yes. Trondheim is at 63.4°N, about three and a half degrees of latitude north of Oslo, and a moderately active night is often enough for a glow low in the north over the Trondheimsfjord. In Oslo a night like that brings a faint arc at most, and it takes a geomagnetic storm to put color over the city. In Trondheim it is the city's own light that hides the weaker displays, which is why people head up to Bymarka or out to the shore at Lade.
Is Gråkallen a good place to watch the northern lights?
Yes, if you want height above the city. Gråkallen is a 552 m summit in Bymarka, about 7 km west of the center, with the city lights below and views in several directions. Park or get off the bus at Skistua and walk about 1.5 km up; the path is open all year. The round radar dome on top is a landmark you can see from the city.
What Kp index do I need to see the northern lights in Trondheim?
In Trondheim, you usually need at least Kp 2 to have a reasonable chance of seeing the northern lights. Lower Kp can still bring a faint aurora display low on the northern horizon, but it is less common.
This is based on magnetic latitude, and Kp index is a global geomagnetic index, so treat it as a rule of thumb, not a location-specific guarantee.
Tonight, the NOAA Kp index forecast is 1.1 to 2.7. That is around the usual Kp index threshold for Trondheim, so you might have a chance of seeing the aurora if the sky is clear and dark.
