Aurora: Forecast & Alerts

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.
