Northern lights in Umeå tonight
Northern Sweden · 64° magnetic latitude · Kp 2–3 threshold
Kp 1 is below the threshold for Umeå. Activity would need to rise to Kp 2–3 before aurora could reach this latitude.
7-day outlook for Umeå
Based on CME arrival predictions from NASA DONKI. Arrival times ±6 hours.

What Kp is needed here?
Umeå sits at a magnetic latitude of approximately 64°N. The Kp index - a global measure of geomagnetic activity on a scale from 0 (quiet) to 9 (extreme storm), updated every 3 hours - needs to reach Kp 2–3 before the auroral oval expands far enough south to be visible from here.
At Kp 2–3, visibility is possible from Umeå but skies need to be clear and dark. Cloud cover and light pollution remain the main obstacles even when Kp is high enough.
Best dark sky sites near Umeå
Light pollution is the biggest obstacle after cloud cover. These sites give you the best dark northern horizon within reach.
Nydala lake, north Umeå
Get directions ↗The lake north of the urban area gives a north-facing open water horizon with less surrounding light than the city centre. In winter the ice surface removes tree obstructions. This is the most practical quick dark sky position for Umeå residents - close enough to reach in 15 minutes on a clear night when a forecast shows Kp rising. Not as dark as the coast or forest positions further out, but accessible and usable at Kp 3+.
High Coast (Höga Kusten)
Get directions ↗The UNESCO World Heritage High Coast features dramatic post-glacial landscape - some of the highest coastline in the world due to land uplift since the last ice age. The elevated coastal positions face the Gulf of Bothnia to the east and open Baltic sea to the south-east. Light pollution is minimal along the coast road south of Härnösand. The dramatic landscape and coastal dark sky make it one of the best aurora positions in northern Sweden for moderate Kp.
Täfteå nature reserve
Get directions ↗Boreal forest and wetland reserve north of Umeå. Open clearings within the forest give north-facing sky positions away from city light. The reserve access tracks are ploughed in winter and the flat terrain makes it accessible without specialist equipment. A practical intermediate option between the quick lake position near the city and the longer drive to the High Coast.
Best time to see the northern lights in Umeå
At 64°N magnetic latitude, Umeå has one of the longest aurora seasons in the world. Meaningful darkness returns in late August and displays are possible on almost any clear night from September through March. Only the endless daylight of May, June, and July rules out viewing completely.
Activity peaks around the September and March equinoxes, when Earth's magnetic field geometry is most favourable for coupling with the solar wind. Events during these two windows tend to produce the strongest displays of the year for observers at Umeå's latitude.
May through July is effectively impossible for aurora viewing: the midnight sun keeps the sky bright around the clock at this latitude. No storm level, not even G5, can produce a visible display without astronomical darkness.

How often does the aurora appear in Umeå?
Average nights per month the Kp reached Umeå's threshold of 2+, from 15 years of geomagnetic data (2010–2024).
Counts the Kp 2+ threshold only - cloud cover and local darkness are not included.
