Threshold for Cairngorms: Kp 3-4 Magnetic latitude: ~57°N Updated: 10 May, 11:05 UTC

What Kp is needed here?

Cairngorms sits at a magnetic latitude of approximately 57°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 3-4 before the auroral oval expands far enough south to be visible from here.

At Kp 3-4, visibility is possible from Cairngorms 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 Cairngorms

Light pollution is the biggest obstacle after cloud cover. These sites give you the best dark northern horizon within reach.

Tomintoul & Glenlivet Dark Sky Discovery Site

An official Dark Sky Discovery Site within the Cairngorms National Park. The highest village in the Highlands at 345 m, with very dark surrounding moorland.

Glenmore Forest Park & Loch Morlich

Below Cairn Gorm mountain. The loch gives a reflective foreground and the forest blocks southern light domes. Wide open sky to the north.

Cairn Gorm mountain road

The ski centre road gives access to altitude (over 600 m at the car park) above valley haze. One of the highest accessible driving roads in Britain.

Common questions

Aurora watching in the Cairngorms - where to go and what to expect.

Is the Cairngorms a good place to see the northern lights?
One of the best in the UK. The Cairngorms National Park is the largest national park in Britain, at ~57°N magnetic latitude with very dark skies, high-altitude access, and officially designated dark sky discovery sites. Kp 3-4 is enough on a clear night from the park.
Where exactly in the Cairngorms is best for aurora?
Tomintoul is the highest village and has an official dark sky designation within the park. The Glenmore Forest area near Loch Morlich gives a dramatic foreground and dark northern sky. The Cairn Gorm mountain road gives altitude above any valley cloud or haze.
Is there an aurora dark sky designation in the Cairngorms?
Yes. The Tomintoul & Glenlivet area has a Dark Sky Discovery Site designation. The broader national park has very low light pollution across most of its 4,500 km² area.
Can you see the northern lights from Aviemore?
From the edges of the town, yes during moderate events. Aviemore itself has some light pollution, but it is modest compared to most Scottish towns. Drive 5-10 minutes in any direction and conditions improve markedly. The Glenmore road is the most popular option.
What is the best time of year for aurora in the Cairngorms?
October and March are the most active months statistically. The park is also famous for clear, cold, dry spells in winter when high pressure settles over Scotland. These anticyclonic conditions produce excellent transparency for aurora viewing.
