Aurora in Helsinki
Helsinki sits at 60.2°N, south of the core auroral zone. Aurora viewing here more often depends on a southward expansion of the oval, making predicted Kp and geomagnetic latitude especially useful for the hourly outlook.
Around Helsinki, long northern nights can provide extended observing windows, but local cloud cover still decides whether an active aurora is visible from the ground.
All times on this page use the local Europe/Helsinki time zone. The forecast combines current auroral activity, predicted Kp, darkness, Moon conditions and local weather to estimate practical viewing conditions near Helsinki.

FAQ — Helsinki
How is Viewing Score calculated for Helsinki?
Viewing Score is a local 0–100 estimate rather than an official NOAA probability. The current score starts from the aurora chance for Helsinki; future hours adjust auroral activity using the predicted Kp.
Darkness, cloud cover and Moon illumination then modify the result. Cloud cover only affects the score when the “Include clouds in score” switch is enabled. Daylight can reduce the score to zero, while a bright Moon above the horizon applies a smaller penalty.
