Climate and Average Weather in Finland
The ideal time to visit Finland is May through September when the weather is warm. A quarter of Finland's territory lies within the Arctic Circle and the midnight sun can be experienced around this time of the year. The further north you travel, the more days the midnight sun can be experienced. At Finland's northernmost point, the sun does not set for 73 consecutive days during summer, and does not rise at all for 51 days during winter, when the Aurora Borealis illuminates the sky.
Finland is one of the few countries in the world whose surface area is still expanding. Owing to the post-glacial rebound that has been taking place since the last ice age, the surface area of the country is expanding by about 7 square kilometres (2.70 sq mi) annually.
