Aurora forecasting, done honestly
Know which nights are worth it.
Auroral folds aurora strength, cloud cover, moonlight and sky darkness into a single 0–100 viewing score for your exact location — and only alerts you when the sky is actually clear enough to see anything.
One verdict, not a wall of numbers.
Most aurora apps shout “high activity!” while you’re standing under solid cloud. Auroral doesn’t.
One clear verdict
A single nightly score and a plain-language call — go out, worth a look, or not tonight — built from live data for where you are.
Cloud-aware alerts
Notifications fire only when conditions genuinely line up. No false alarms on cloudy nights. This is the whole point.
Plan the week
A 10-night outlook so you can pick your night, plus a live map of the aurora oval to see where the lights are right now.
Built for the field
Night-vision red mode keeps your eyes dark-adapted while you’re out, so checking the app doesn’t cost you the view.
Both hemispheres
Northern lights or southern — check any city on Earth. No sign-up, no account, ever.
Data you can trust
Aurora activity from NOAA, cloud forecasts from the Norwegian Meteorological Institute, plus light-pollution and moon-brightness modelling.
