UK aurora forecast

Northern lights potential, with the weather that could help or hide the view. Choose a UK peak and check the night, not just the activity level.

Choose a peak or viewpoint

Snowdon - Yr Wyddfa

Forecast at the named peak, not a recommendation to climb it at night. Lower viewpoints can have different cloud and horizons.

Night beginning Friday 25 September 2026. Times are UK local time.

Aurora is unlikely on this night

Forecast activity is currently too weak for a likely sighting here. Forecast activity peaks near Kp 3.7 on the 0 to 9 scale. Roughly Kp 5.7 may bring a camera view near the northern horizon, but this is not a firm threshold.

Cloud information is incomplete for this night. Viewing potential depends on clear skies.

A bright Moon is above the horizon around the best forecast hour and may wash out faint aurora detail. A stronger display may still be visible.

Aurora can change at short notice. Check again before travelling; a forecast is not a guaranteed sighting.

Local sky conditions

Best available dark spell: 26 Sep, 04:00 BST to 05:00 BST.

Mixed sky conditions

Mostly clear skies are forecast. Moonlight washes out fainter stars.

A bright Moon remains above the horizon through full darkness, washing out fainter stars and meteors.

Near-full moon, about 99% illuminated.

Full darkness: 25 Sep, 21:05 BST to 26 Sep, 05:10 BST.

Moon-free darkness: none within this overnight period.

Moonrise around 25 Sep, 18:30 BST.

Moonset around 26 Sep, 06:35 BST.

Can I see the northern lights tonight?

Activity is only one part of the answer. Cloud, darkness and a clear view towards the display matter too. Our forecast separates activity guidance from viewing conditions, and says when either is unavailable.

Look for an accessible viewpoint with an open northern horizon. A summit is not essential. A camera may show faint colour that is hard to see by eye. Activity can change quickly, so check again close to the time.
