Aurora Borealis in Greenland

Greenland · 64.18°, -51.72° · geomagnetic 72.6° · needs Kp 3

Tonight in Greenland

37%

Peak chance of a visible display tonight, from the same model the Revon app runs. Greenland needs Kp 3 before anything clears the northern horizon, and tonight the forecast peaks at Kp 5.7 — comfortably over the line.

The next 30 nights in Greenland

Every night to come, scored the same way as tonight. The best of the open week is Sunday 2 Aug at 37%. 4 of the seven reach the Kp 3 that Greenland needs, topping out at Kp 5.7. The 23 nights past the seven-day window move with the 27-day solar rotation and are updated daily in the app.

Moderate aurora activity tonight around 4 AM. Similar conditions expected on August 19th.

You are inside the auroral oval

Greenland sits far enough northern that quiet conditions are enough. What limits you here is cloud and moonlight, not geomagnetic activity.

Solar declination and hour angle at −18°

Nothing to see from April to August

Through those months the sun never falls more than 18° below the Greenland horizon, so the sky never darkens fully. Plan around the darker half of the year.

Getting clear of the light

Greenland is small enough that its own lights are a minor problem — the centre reads Bortle 2. Walking to the edge of town is often escape enough.

The months that actually deliver

Counting only nights that were both stormy enough and dark enough, March, September and October came out ahead in Greenland. That is storm season and darkness overlapping — the equinoxes tend to be geomagnetically active, and the nights are already long by then.

Darkest nights of the coming year

A bright moon washes out a weak display as effectively as street lighting. These new moons fall inside the Greenland viewing season.

Where it is close to a certainty

Nuuk is close enough to reach and return in a night — 0 km north — and needs only Kp 3.

Where the horizon opens up near Greenland

The display sits low on the northern horizon, so what beats a better forecast is open ground facing that way. Height gets you above the town glow; water gives you an unbroken skyline. These are within a short drive of Greenland.

Common questions about the aurora borealis in Greenland

Can you see the aurora borealis from Greenland?

Yes. On the last 10.0 years of NOAA Kp records, Greenland had about 113.3 nights a year 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. Greenland sits at geomagnetic latitude 72.6°, and the auroral oval only reaches that far from the pole once activity hits Kp 3.

When is the best time of year to see the aurora borealis in Greenland?

March, September and October. Those months scored highest once both conditions are counted together: geomagnetic activity and enough hours of real darkness. From April to August the sky over Greenland never gets fully dark, so nothing is visible however strong the storm.

Where can you escape the light pollution near Greenland?

The centre of Greenland reads Bortle 2. The nearest sky at Bortle 2 is about 8 km north around Nuuk. On a marginal night that drive matters more than the forecast does.

Where is the nearest place to Greenland with reliable aurora borealis?

Nuuk, Greenland — 0 km north. It needs only Kp 3 and averages 171.4 viable nights a year against 113.3 in Greenland.
