One of the natural phenomenons Finland is famous for is the northern lights, or the Aurora Borealis. These pretty lights can be found in Lapland, Finland’s northernmost region. The lights are visible around 200 nights a year, or every other clear night.
Nights in Finland are dark enough for anyone to view the Northern Lights as long as the skies are clear and you have a bit of luck. The lights become more visible as you travel further north. Ideal viewing periods would be from late August to early April. In southern Finland, the lights are visible only up to 20 nights a year.
The Finnish Meteorological Institute (FMI) has a space weather service to monitor auroras in Finland. They update periodically on their Auroras Now! website.
The northern lights are caused by electronically charged particles that come from the sun. The lights form at very high altitudes, being over 100 km above sea level. The colours come when these particles interact with the atmospheric gases around the area.
