When is the best time to see northern lights in the UK?
The useful viewing window is where darkness, elevated activity and a clear sky overlap. A fixed clock time cannot tell you when a display will reach your location. Build a plan around the night you can actually watch.
Find your northern viewing directionHow to choose an hour to watch
Use the calculated darkness window as your starting range. Select an hour within it and check the cloud estimate for that hour. Then consult current activity and the official outlook. A storm can develop outside a commonly suggested viewing time, so revisit the forecast instead of treating midnight as a deadline.
Read dates across midnight
A plan for Monday night includes early Tuesday morning. SunPoint keeps the evening's date in the night selector and advances the weather timestamp for an hour after midnight. Every displayed solar time includes GMT or BST; this also helps when clocks change in autumn or spring.
Leave time to get ready
Use sunset to plan your arrival and daylight inspection of the horizon. Choose a short, familiar route if the forecast is uncertain. Compare the cloud estimate again before leaving, then use your saved plan to return to the same pin. Moon illumination is context, not an aurora probability: the planner's Moon check is for local midnight.

Edinburgh · 55.9533, -3.1883. North is a starting direction, not a prediction of where an aurora will appear. During strong activity, check overhead and other directions too. This map does not assess cloud, horizon obstruction or darkness on the ground.

Full darkness is a planning aid, not a required start time: a bright aurora can show during twilight. There is no fixed aurora arrival time. No crossing means that solar threshold is not crossed on this date.
Moon at local midnight: 3% illuminated · below the calculated horizon. This does not describe the whole night.
Cloud at your chosen time
Cloud forecast unavailable
Forecasts cover the provider's available dates. Missing data does not mean clear skies.
1. Check activity
Read the current AuroraWatch UK status and the Met Office outlook. This planner does not display a live geomagnetic alert.
Check current AuroraWatch UK status ↗2. Check the sky
Cloud can hide the display. Compare the local cloud estimate above with a current forecast for your route and viewing position.
Check the Met Office cloud map ↗3. Check the horizon
Use the north-facing guide, then assess buildings, hills and trees in person. Choose a familiar accessible spot and check local access and weather.
Read AuroraWatch UK's direction advice ↗Start with the night, rather than a countdown
Choose your location and the date on which the evening begins. Sunset is not the start of the darkest sky: civil twilight and full astronomical darkness come later. In northern UK summer, full darkness may not occur. The planner shows missing crossings rather than inventing a time.
AuroraWatch UK: when aurora is visible ↗What will you actually see?
A faint aurora may look like a pale glow or band by eye. A camera can record colours your eyes do not pick up as clearly. Try a steady phone night-mode photo, but do not treat colourful photographs as a promise of the same naked-eye view. Look for changing structure; ordinary cloud and urban skyglow can also colour a photograph.
When should I arrive?
Use sunset and twilight times to plan access and set up before it is fully dark. Leave time for your eyes to adapt, keep screen brightness low and recheck activity. The calculated darkness window tells you about sunlight, not when a solar storm will arrive.
Aurora forecasts, regional guides and practical advice
Northern lights questions
Is midnight always the best time?
No. Activity can change during the night. Check the forecast alongside local darkness and cloud.
Can I watch immediately after sunset?
Twilight can still make a faint display hard to see. Compare dusk and full darkness for your location.
Why is there no full darkness time in summer?
At northern latitudes the Sun may not drop far enough below the horizon that night.
Does the Moon prevent all sightings?
Moonlight can affect contrast, but illumination alone cannot predict whether aurora will be visible.
Which date should I use after midnight?
Keep the date the evening starts. The planner assigns early-morning hours to the next day.
