Aurora borealis forecasts in the United Kingdom

There is no single aurora borealis forecast for the United Kingdom, and any number offered as one would be wrong almost everywhere in it. The auroral oval reaches part of the country on a quiet night and the rest of it only during a storm: Kilmarnock needs Kp 5, while St Austell needs Kp 7 — a storm level that arrives a fraction as often.

So this page is a directory rather than a forecast. Each of the 789 places below has its own page with tonight’s hourly odds, the next 30 nights, and the drive to darker sky that matters more than the forecast does.

Where the aurora borealis is visible on the most nights in the United Kingdom

Counting only nights when the storm was strong enough for that location and the sky there was dark enough at the same time. That is why the far north of the United Kingdom does not automatically top the list: the closer a place is to the pole, the more of its summer never gets dark at all.

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. In the United Kingdom those thresholds run from Kp 5 to Kp 7. A place at Kp 5 needs no more than a moderate storm, which arrives several times a year; one at Kp 7 needs a severe storm, and those come a handful of times per solar cycle.

Common questions about the aurora borealis in the United Kingdom

Can you see the aurora borealis in the United Kingdom?

Yes, in all 789 places in the United Kingdom with a forecast page: each averages at least one viable night a year, and Kilmarnock leads them at 22.9 nights.

Where in the United Kingdom is the aurora borealis seen most often?

Kilmarnock. It needs Kp 5 and averages 22.9 viable nights a year, more than anywhere else in the United Kingdom we publish a forecast for. Further north is not automatically better: the closer a place is to the pole, the more of its summer never gets dark at all.

What Kp index do you need to see the aurora borealis in the United Kingdom?

Between Kp 5 and Kp 7, depending where you stand. Kilmarnock needs Kp 5; St Austell needs Kp 7, and storms that size are a small fraction as frequent.

Is there one aurora borealis forecast for the whole of the United Kingdom?

No. The auroral oval reaches some parts of the United Kingdom on a quiet night and others only in a severe storm, so a countrywide number would mislead more than it told you. The forecast is published per place, so open the page for where you will actually be.
