Canada spans geomagnetic latitudes 51.2°–63.3°, so the same planetary storm is felt differently across it — higher magnetic latitudes get noticeably more. Open a city page for storm timing in its local time, its aurora threshold and wellbeing guidance.

FAQ

Canada: quick answers

Which cities in Canada feel geomagnetic storms the strongest?

The higher the geomagnetic latitude, the stronger the effect. Among the listed cities the most exposed are Fort McMurray, Grande Prairie, St. Albert.

Can you see auroras in Canada?

It depends on latitude: Canada's cities sit between geomagnetic 51.2° and 63.3°. The closer a city is to the auroral oval, the lower the Kp it needs — each city page shows its own threshold and tonight's estimate.

Is the forecast different across Canada?

The Kp index is planetary — the same for all of Canada. What differs is the effective local exposure (3.1–3.4 at the coming peak) and the timing, which each city page shows in its own timezone.
