Real-time aurora forecast updated every 15 minutes
Kp 1.7 is well below the Kp 4 that Alberta needs, so the aurora stays too far north tonight.

10-Night Aurora Outlook
Planning a trip to Alberta? Peak activity, cloud cover, and darkness for the nights ahead.
Kp ~ marks nights beyond NOAA's precise 3-day forecast, estimated from the 27-day outlook. Treat the far nights as a rough guide, not a promise.
Seeing the aurora in Alberta
Alberta is one of the best places in Canada to catch the northern lights, and the province is stitched together with certified dark-sky preserves that prove it. Jasper National Park is a world-famous dark-sky preserve with a town inside its borders, and far to the north Wood Buffalo National Park is the largest dark-sky preserve on Earth. Around Edmonton and central Alberta, at roughly 53 degrees north, the auroral oval swings overhead often enough that a clear, dark night and Kp 4 can be all it takes.
Our verdict is not a Kp number. The Kp index is a global, three-hour average, and treating it as a promise is the single biggest reason people drive out and see nothing. Instead we check four things for Alberta specifically: whether forecast activity reaches the level this latitude needs, whether the sky will be clear, whether it will actually be dark, and how much moonlight and local light pollution will wash out. Only when all four line up do we say yes.
When to go: aurora season in Alberta
Aurora season in Alberta runs from late August through mid-April. The sun does not switch off in summer: the sky over central and northern Alberta simply never gets dark enough for long enough in June and July for even a strong storm to show. The strongest displays cluster around the September and March equinoxes, when Earth's magnetic field couples more efficiently with the solar wind and the same activity produces bigger shows.
Through the current solar maximum, central Alberta around Edmonton has been catching photographable aurora on many nights each month, and a handful of storms a year push naked-eye color well south toward Calgary and the U.S. border. Those big nights are what the 10-night outlook above is built for: when a Kp 5 or 6 storm is on the way, it usually shows up there two or three days ahead.
Alberta's dark-sky preserves
Alberta protects more certified dark sky than almost anywhere on the continent, and that is its aurora advantage. Jasper National Park is one of the largest accessible dark-sky preserves in the world, with the town of Jasper sitting inside its borders, while far to the north Wood Buffalo National Park is the largest dark-sky preserve on Earth. Closer to home, the Beaver Hills preserve around Elk Island National Park gives Edmonton residents genuinely dark skies within an hour's drive.
Which preserve you choose comes down to how far north you are willing to travel. The further north you go, the lower the Kp you need: Wood Buffalo and the Fort McMurray area sit almost under the auroral oval, while Cypress Hills in the far south needs a stronger storm to deliver. For most Albertans, Elk Island or a dark rural road with an open northern horizon is the practical pick on a promising night.
How to read tonight's forecast like a local
From central Alberta you generally need about Kp 4 for a naked-eye show under a dark sky, and roughly Kp 3 for your camera to catch a glow on the northern horizon. Far northern Alberta sees aurora at even lower numbers, while the Calgary area and the southern prairie usually want Kp 5 or 6. Locals know the Kp number is only the entry ticket: a clear north horizon and real darkness matter just as much, which is why the verdict above folds cloud cover and twilight into one answer instead of leaving you to juggle three apps.
On a promising night, get out early, give it at least two hours, and let your eyes dark-adapt for 15 minutes without looking at your phone. Displays arrive in substorms: bursts of 15 to 40 minutes with quiet gaps between them, usually peaking between about 10 pm and 2 am. Point night mode at the northern horizon now and then, because the camera will pick up an approaching display before your eyes do.
