Weather in the Oulu Area
Finland is located in the zone of the prevailing westerly winds where tropical and polar air masses meet. Therefore weather types can change rapidly and the variations in the weather conditions from one year to another can be vast.
You should keep in mind that we have a cold winter in Finland. To give you some idea of what is waiting for you, a table of average weather conditions in Oulu is provided below.
