Frequently Asked Questions
What weather conditions are best for seeing northern lights?
The best weather for northern lights viewing includes clear skies (less than 30% cloud cover), high Kp index (3 or higher), and dark conditions between 21:00-03:00. Our real-time forecast combines all these factors to give you an accurate aurora visibility prediction.
How accurate is the northern lights forecast?
Our aurora forecast uses real-time data from NOAA Space Weather Prediction Center for Kp index and Open-Meteo for weather conditions. The forecast is most accurate for the next 24-48 hours, with decreasing accuracy for longer periods.
What is the Kp index and why is it important?
The Kp index measures geomagnetic activity on a scale of 0-9. Higher values indicate stronger aurora activity. For northern Norway, Kp 3+ usually means good aurora visibility, while Kp 5+ indicates excellent conditions with aurora visible even further south.
