Aurora borealis forecasts in Greenland
One place in Greenland has a forecast page of its own so far: Nuuk. It needs Kp 3 before anything clears the northern horizon, and averages 113.3 viable nights a year — nights when the storm was strong enough and the sky dark enough at the same time.
There is no separate forecast for Greenland as a whole, and a single number offered as one would not tell you anything you could act on. What matters is the sky above wherever you are standing, so the forecast lives on that place’s own page.

What the Kp number means
Kp grades the strength of a geomagnetic storm from 0 to 9. The higher it runs, the further from the pole the auroral oval spreads, so every place has a Kp at which the aurora borealis first reaches it — that is the number beside each link above. Everywhere we forecast in Greenland sits at Kp 3.

Common questions about the aurora borealis in Greenland
Can you see the aurora borealis in Greenland?
Nuuk is the one place in Greenland with a forecast page, and it averages 113.3 viable nights a year — nights when the storm was strong enough and the sky dark enough at the same time.
What Kp index do you need to see the aurora borealis in Greenland?
Kp 3, at Nuuk — the one place in Greenland with a forecast page. Below that the auroral oval does not reach it.
Is there one aurora borealis forecast for the whole of Greenland?
No. What you can see depends on the sky above the spot you are standing in — how dark the night gets there, the cloud and the moon — not on a national average. The forecast is published per place, so open the page for where you will actually be.
