Where can you see the aurora?
The aurora — the northern lights in the Arctic and the southern lights in the far south — sits in a ring around each magnetic pole. The stronger the geomagnetic storm, the further that ring pushes toward the equator. Here's how far it reaches, and the places under it.
How far the aurora reaches, by activity
| Activity | Northern hemisphere | Southern hemisphere |
|---|---|---|
| Kp 0–3any clear, dark night | Tromsø, Fairbanks, Iceland, Yellowknife | Antarctica (almost no land) |
| Kp 4–5active nights | Scotland, Oslo, Stockholm, Calgary | Open ocean — almost no land |
| Kp 6–7strong storms | London, Berlin, Seattle, Chicago | Tasmania, southern New Zealand |
| Kp 8–9severe storms | Texas, Florida, southern Europe | Melbourne, Sydney, South Africa |
| Extremerarest superstorms | Mexico, Hawaii, the Caribbean | Queensland, central Chile |
It's your geomagnetic latitude, not the one on the map
The aurora forms around the magnetic pole, which sits over Arctic Canada — not the geographic North Pole. So North America is tilted toward the oval: Yellowknife (62°N) and Churchill (59°N) are world-class, while in Europe you have to reach about 69°N — Tromsø — to see the same show. Same lights, roughly 7–10° of latitude difference. That's why we convert every location to its geomagnetic latitude before deciding.
Why the northern lights are easy and the southern lights are hard
A long arc of inhabited land sits directly under the northern oval — Scandinavia, Iceland, Alaska, northern Canada and Russia — so millions of people can see the northern lights on a normal clear night. The southern oval is almost entirely over the Southern Ocean and Antarctica, with barely any land beneath it. Only Tasmania, southern New Zealand and Patagonia catch the southern lights from land — and mostly low on the horizon, on active nights. Same physics; far harder geography.
Darkness still decides every night
Sit directly under the oval in June and you'll still see nothing — the Arctic midnight sun never lets the sky darken. That's why the season is the dark half of the year (about September to March in the north), and why our verdict gates on the sun's position, cloud and the moon — not just the Kp number.
The once-a-century exception
During the most extreme storms, the oval balloons astonishingly far. The 1859 Carrington Event put aurora over the Caribbean and Hawaii; the May 2024 superstorm reached Mexico, southern Europe and mainland Australia. The theoretical floor is “almost anywhere” — but only for a night every few decades. Read what the Kp index means to know when one is coming.
Where to see the northern lights
Where to see the southern lights
The southern auroral oval sits mostly over open ocean, so these are the few inhabited places close enough to catch aurora australis — looking south over a low horizon when a storm pushes the lights toward the equator. Ushuaia sits much closer to the geomagnetic equator than its 55° S map latitude suggests — about 43° geomagnetic, because the south magnetic pole is offset far toward Australia — so it needs a stronger storm than most visitors expect.
