Tonight's chance of northern lights where you are, the best hours to look up, 7-day forecast, and an alert when a night looks genuinely good. Know which nights are worth it. Aurora gives you one clear answer each evening: tonight's chance of seeing the northern lights where you are, how sure the forecast is, and the best hours to look up. TONIGHT • Tonight's chance in percent, with a confidence level • Best viewing hours: the clearest dark hours at your location • Why: clouds, darkness, moonlight and space weather, in plain words PLAN AHEAD • Three nights ahead, with tonight's cloud cover hour by hour • A 7-night outlook of darkness and moonlight • Any destination: check Tromsø, Abisko, Iceland or Lapland before you go ALERTS • A planning alert on afternoons when tonight looks genuinely good • An optional heads-up when conditions turn strong during the night • You choose how good is good enough, and set quiet hours BUILT FOR REAL CONDITIONS Aurora combines space weather from NOAA and GFZ with MET Norway's cloud forecasts for your exact spot, instead of relying on the Kp index alone. In backtests over three winters of all-sky camera data in northern Scandinavia, nights rated Excellent had clearly visible aurora 79% of the time. A forecast, not a guarantee: the aurora is unpredictable and conditions can change within minutes. Your location is only used approximately (about 5 km) and only while the app is open. No account, no ads. SUBSCRIPTION Aurora is available with a weekly or yearly subscription. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your Apple Account settings.
