About the Finland Aurora Forecast
The AuroraVision forecast for Finland uses real-time data from NOAA's Space Weather Prediction Center, updated every 2 minutes. Our visibility score combines solar wind Bz, speed, particle density, magnetic field strength, and local cloud cover.
Finnish Lapland spans from Rovaniemi at the Arctic Circle (66.5°N) to Inari near 69°N — well inside the auroral oval. Finland sees aurora on average 200 nights per year in northern Lapland. The dark, snow-covered fells reflect aurora light creating a magical double display.

Key Forecast Factors
Five data points that determine aurora visibility in Finland
Bz (nT)
Southward Bz is the primary trigger. Finnish Lapland at 66–69°N is inside the auroral oval during strong activity.
Solar Wind Speed
High speed (>500 km/s) drives aurora deeper into the oval. Finland's latitude benefits from moderate to strong solar wind.
Magnetic Field Bt
Total interplanetary magnetic field. Strong Bt combined with southward Bz produces the best Finnish aurora.
Particle Density
Solar wind proton density. Higher density amplifies aurora intensity across all Finnish Lapland locations.
Cloud Cover
Finnish Lapland winters are often clear and cold. The eastern fells near Russia tend to have drier, clearer conditions.
Best Viewing Window in Finland
Best viewing window is 21:00–02:00 local time (UTC+2 in winter). Finnish Lapland has polar night in December and January — prime time for all-night aurora hunting. Kaamos (polar night) means complete darkness and the best aurora windows of the year.
