Frequently Asked Questions

Can you see the Northern Lights in Alberta tonight?

Alberta: it depends on where you are and on tonight's sky. Fort McMurray needs about Kp 2; Lethbridge needs about Kp 4. On top of 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 Alberta?

Alberta has no single number. The higher the Kp, the further from the pole the auroral oval reaches, so the threshold rises with distance from the pole: Fort McMurray needs about Kp 2, Lethbridge about Kp 4. Each city's page gives its own threshold.

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

September to April, with November to February giving the most hours of real darkness. The March and September equinoxes carry a statistical tilt toward higher activity — a shift in the odds, not a promise for any one night.

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

Alberta: of the places in this list, Fort McMurray needs the least — about Kp 2 — while Lethbridge needs about Kp 4. Wherever you are, a dark sky away from city lights matters more than the exact spot.
