Where can you see the northern lights in Belgium?
10 of the 27 places on Yozora Atlas in Belgium see the northern lights on their northern horizon in a storm of Kp 7 or less. Bosland National Park, Flanders, needs only Kp 7, a strong storm, which has happened on about 5 nights a year since 1932. At the southern edge, in Antwerp, it takes a strong storm (Kp 7), about 5 nights a year. Those are nights with enough activity, not sightings: clouds and the moon hide many of them.
Which parts of Belgium see the northern lights most often?
Each region with the Kp range of its places, the nights a year its best place reaches that level, and the darkest place to watch from.
| State or region | Places | Kp needed | Nights a year | Darkest place to watch from |
|---|---|---|---|---|
| Flanders | 10 | Kp 7 | 5 nights | none at Bortle 4 or darker |

The towns in Belgium where the northern lights show most often
Nights a year since 1932 with the Kp level the place needs, between 9 pm and 3 am. These are nights with enough activity, not sightings: clouds and the moon hide many of them, and away from the far north a display is often a faint glow low in the north that a phone camera shows better than the eye. From inside a town only bright displays show through the glow: each town page names the closest dark spot without the town in its northern sky.
When are the northern lights most likely in Belgium?
Averaged over the 10 places, the most nights with a strong enough storm during darkness come in March and April: geomagnetic storms are more frequent around the equinoxes, and the nights are long enough to see them. Clouds are not counted here; each place page has its clear nights by month.
How the Kp levels and night counts for Belgium are worked out
The aurora forms in a ring around the magnetic north pole, and the stronger a geomagnetic storm, the further south it reaches. Storm strength is measured by the Kp index, from 0 (quiet) to 9 (extreme). For each place the Kp level comes from its magnetic latitude, using the rule NOAA uses: the edge of the aurora sits at 66.5° magnetic latitude at Kp 0 and about 2° further south per step. It can be off by one level, and a phone camera often shows a display the eye barely sees. How often that level was reached comes from the Kp record of GFZ Potsdam, 1932 to 2025. None of this is a forecast: for tonight, see NOAA’s 30-minute aurora forecast. How it works
