Why these months?

Two things decide your odds in Fort Smith: darkness and activity. You need real darkness — so the bright midnight-sun months are out no matter how strong the aurora is. On top of that, geomagnetic storms run statistically stronger around the spring and autumn equinoxes (the Russell–McPherron effect), which is why September and October and March and November tend to edge out the dead of winter. Fort Smith's season runs mid-august to april.

Fort Smith sits on the Northwest Territories–Alberta border at the edge of Wood Buffalo National Park, the largest Dark Sky Preserve in the world. High geomagnetic latitude plus dry boreal air makes it one of Canada's most reliable aurora spots outside Yellowknife.

Where to stand in Fort Smith
