The Upper Peninsula is one of the best places in the lower 48 to see the aurora borealis. Here's the live Kp index, tonight's outlook, cloud cover by city, and exactly where to go.

The Kp index (0–9) measures global geomagnetic activity. Because the UP sits at roughly 55–57° geomagnetic latitude — unusually high for the lower 48 — you need less activity here than almost anywhere else in the continental US.
| Kp | NOAA Scale | What you'll see from the UP |
|---|---|---|
| 0–2 | Quiet | Nothing visible. Enjoy the stars. |
| 3 | Unsettled | Faint glow possible on the northern horizon from very dark shoreline spots — usually camera-only. |
| 4 | Active | Real chance of visible green bands low over Lake Superior. Worth going out if skies are clear. |
| 5 | G1 Minor Storm | Usually visible to the naked eye on the northern horizon. Pillars and motion possible. |
| 6 | G2 Moderate Storm | Good display — arcs climbing well above the horizon, color visible to the eye. Drop what you're doing. |
| 7 | G3 Strong Storm | Aurora overhead. Reds and purples possible. This is the night people drive hours for. |
| 8–9 | G4–G5 Severe/Extreme | Once-in-years event — visible across the entire sky, even from town. Cancel your plans. |
The formula: dark skies, and an unobstructed view north over Lake Superior. The lake gives you a flat, light-free horizon for a hundred miles — that's why the UP beats inland spots at the same latitude.
The premier aurora perch in Michigan. 700+ feet above Superior with a panoramic north view and near-zero light pollution. The drive itself is a destination. Nearby Keweenaw Dark Sky Park (Keweenaw Mountain Lodge) is certified dark-sky territory.
Minutes from town but pointed straight north over open water. The Black Rocks area is the classic foreground. Expect company on big storm nights — this is the UP's most photographed aurora spot.
A sand spit jutting into Superior with a 180° water horizon and the Great Lakes Shipwreck Museum lighthouse as a foreground. One of the darkest easily-reached shorelines in the east UP.
Tiny town, huge north-facing bay, almost no light dome. Pairs perfectly with a Pictured Rocks trip — and the drive along H-58 has multiple dark pull-offs.
The Porkies' Lake Superior shoreline campgrounds face due north with wilderness-grade darkness. Lake of the Clouds overlook works for high-activity nights when the aurora climbs the sky.
Flat, north-facing beach five minutes from Munising with parking at the shoreline. Light dome from town is modest; walk east up the beach for darker skies.
Miles of drive-up shoreline where you can watch from the car — the move for cold nights and quick "the Kp just spiked" runs. Great Sand Bay is a standout.
| ✅ | Kp 4+ forecast or live (check the top of this page) |
| ✅ | Clear northern sky — cloud table above |
| ✅ | 10 PM – 2 AM is the statistical sweet spot; substorms pulse in 20–40 minute waves |
| ✅ | Dark adaptation — 20–30 min, no phone screens (red light mode if you must) |
| ✅ | Face north over water — the lake is your friend |
| ✅ | Patience — the aurora breathes; a dead hour can explode in minutes |
Geomagnetic activity statistically peaks around the equinoxes — September–October and March–April are the UP's prime windows, combining active sun, long nights, and (in fall) warmer shorelines. Deep winter offers 14+ hour nights but more lake-effect cloud. June–July is weakest: the northern sky never gets fully dark. And through 2026 we're still riding the high plateau of Solar Cycle 25, so strong-storm nights remain more common than average.
Night mode on, brace on a rock or tripod, 3–10 second exposure, focus set to infinity. If the northern horizon shows green in the photo but gray to your eyes — stay put. It's building.

It depends on two things: geomagnetic activity (the Kp index) and cloud cover. From the UP, aurora is typically visible low on the northern horizon at Kp 4–5, puts on a real show at Kp 5–6, and can appear overhead at Kp 7+. The live verdict at the top of this page combines tonight's forecast Kp with current conditions.
The UP sits at roughly 55–57° geomagnetic latitude — among the best in the lower 48. Kp 4 gives you a fighting chance on the northern horizon; Kp 5 (G1 storm) is usually naked-eye visible over Lake Superior; Kp 6–7+ can fill the sky.
Anywhere dark with an open view north over Lake Superior. Top picks: Brockway Mountain and the Copper Harbor shoreline, Presque Isle Park in Marquette, Whitefish Point, Grand Marais, and the Porcupine Mountains' Union Bay. See the full list above.
Most activity peaks between 10 PM and 2 AM local time, arriving in substorm waves 20–40 minutes apart. Give your eyes 20–30 minutes to dark-adapt and plan to stay at least an hour.
September–October and March–April — activity peaks near the equinoxes and nights are long. Winter works (very long nights, more lake-effect cloud). June–July is weakest because the sky never gets fully dark this far north.
Long exposures gather far more light than the human eye. At Kp 3–4, a phone in night mode will often show green bands where you see only faint gray haze. If the camera sees green — stay. It often builds.
