Frequently Asked Questions

Can you see the Northern Lights in Wales tonight?

Wales: it depends on tonight's sky more than on where you are — every place here needs about Kp 6. Beyond that it takes a clear, dark sky: cloud blocks aurora at any Kp. The table at the top of this page has tonight's forecast city by city.

What Kp index is needed to see the Northern Lights in Wales?

Wales: about Kp 6 everywhere. The places on this site sit at similar geomagnetic latitudes, so the threshold is the same. Kp is a probability signal, not a guarantee — it still takes a clear, dark sky.

What are the best months to see the Northern Lights in Wales?

September to April, with December to February the darkest stretch — though at this latitude the season is set by how often a storm reaches you, not by daylight.

Where is the best place to see the Northern Lights in Wales?

Wales: geomagnetically its places are about equal — each needs about Kp 6. What decides the night is cloud and darkness: pick the clearest sky and get away from city lights.
