A few times a year the aurora reaches far south of where it usually shows. We'll email you the day before, and again when it starts.

Yes. Inverness is a genuine Aurora destination on active nights. Inverness sits at a magnetic latitude of about 55.2°N, which means it needs stronger geomagnetic activity before the Aurora climbs into view, but when conditions align, the display can be spectacular. Aurora season here runs Sep – Mar.
Relative viewing probability, combining darkness hours, typical geomagnetic activity, and historical cloud cover for this location.
Scouted for dark skies, an open northern horizon and safe winter access, with sources listed.
Most forecasts rank a place by its geographic latitude. But the Aurora follows Earth's magnetic field, and the two don't line up. Inverness sits at 57.5°N on the map, yet its magnetic latitude is about 55.2°, which determines the real Kp threshold here.
That gap is exactly why generic tools mis-rate locations. We calibrate to magnetic latitude, which is why our minimum Kp here is 5.5.
| Kp 1 | Faint glow low on the horizon |
| Kp 3 | Bright arcs: movement, colour to the eye |
| Kp 5 | Storm: fills the sky, curtains overhead. You're here |
| Kp 7+ | Rare, dramatic; visible far to the south |
Each is calibrated separately, so the Kp they need differs even within Scotland.
Northern lights in Scotland: every destination compared →✓Inverness needs a minimum Kp of about 5.5 for Aurora to become visible, based on its magnetic latitude of 55.2°N.
✓Aurora season runs Sep – Mar, when nights are dark enough and geomagnetic activity is at its seasonal peak.
✓Around magnetic midnight, which falls at about 23:18 local time in Inverness rather than midnight on the clock. That is when Inverness passes closest to the midnight sector of the auroral oval. Activity concentrates in the hours just before it, so plan for roughly 20:30 to 00:30, with 22:30 to 23:30 the strongest hour, and give your eyes twenty minutes to adapt.
