Real-time aurora forecast updated every 15 minutes
Kp 1.7 is well below the Kp 6 that Wyoming needs, so the aurora stays too far north tonight.

10-Night Aurora Outlook
Planning a trip to Wyoming? 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 Wyoming
You can see the northern lights in Wyoming, but it takes a strong geomagnetic storm: the state sits south of the auroral oval, so naked-eye aurora over Grand Teton or Yellowstone usually means a Kp 6 night. What Wyoming does have is darkness. Teton County is the world's first certified Dark Sky County, and the wide, empty basins around Pinedale, Lander, and the Bighorns hold some of the blackest skies in the lower 48, so when a storm does arrive there is nothing between you and the northern horizon.
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 Wyoming 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 Wyoming
Aurora season in Wyoming runs from late August through mid-April. It is not that the sun goes quiet in summer: at 43 to 45 degrees north the sky simply does not get fully dark for long enough in June and July, when late twilight and short nights bury even a strong storm. The best stretch falls around the equinoxes, September and March, when Earth's magnetic field couples more efficiently with the solar wind and the same activity produces a bigger show.
Wyoming sits south of the auroral oval, so the aurora only reaches the state during moderate to strong storms, usually around Kp 6 for a naked-eye display over Grand Teton or Yellowstone. Through the current solar maximum a handful of storms each year have pushed naked-eye color across the state, including the severe May 2024 storm that lit skies across much of the lower 48. Those big nights are what the ten-night outlook above is for: when a Kp 6 or 7 storm is on the way, it usually shows up there two or three days ahead.
Wyoming's dark-sky advantage
Wyoming has some of the darkest skies in the lower 48, and that is its real edge for aurora. It is the least populated state in the country, so once you leave the towns there is almost no light pollution to fight, and the wide, treeless basins give you an unbroken view to the northern horizon where the aurora sits. Teton County, home to Grand Teton National Park and Jackson Hole, is the world's first officially designated International Dark Sky County, and Sinks Canyon State Park near Lander is the state's first certified Dark Sky Park.
Darkness alone does not create aurora, but it changes what a given storm looks like. A Kp 6 night that would be a faint camera-only smudge from a city can stand up as visible green over a black Wyoming basin. The trick is an open view north: drive out to Antelope Flats in Grand Teton, the Lamar Valley in Yellowstone, Fremont Lake near Pinedale, or the sage country around the Bighorns, and let the flat northern horizon do the work.
How to read tonight's forecast like a local
From Wyoming you generally need about Kp 6 for a naked-eye display and roughly Kp 5 for your camera to catch a glow on the northern horizon. Regulars know the Kp number is only the entry ticket: a clear northern horizon and genuine darkness matter just as much, which is why the verdict above folds cloud cover and twilight into one answer instead of making you juggle a Kp map, a weather app, and a sunset table. Read the hourly cloud numbers first, then pick the darkest spot with an open view north that you can reach.
Timing and patience do the rest. Most displays peak between about 10 pm and 2 am local time, when your spot rotates under the most active part of the oval, and the aurora arrives in bursts called substorms, runs of 15 to 40 minutes with quiet gaps between. Get out early, give it two full hours, let your eyes dark-adapt for fifteen minutes without checking your phone, and point night mode at the northern horizon now and then, because the camera will catch an approaching display before your eyes do.
