Climate chart - Rovaniemi (Finland)
The climate of Rovaniemi, the capital of the Lapland province, is cold continental, with freezing winters and mild summers.
The city is located just south of the Polar Circle, but due to atmospheric refraction, the midnight sun can be seen here as well, from 7 June to 6 July.

In December, you can see the sun on the horizon for just over two hours. To observe the polar night, in which the sun does not rise, it is necessary to go further north of about 100 km (60 mi), for example, in Sodankylä, on the days of the winter solstice (December 21st).
