In Finland, most museums and galleries are open year-round, and there is just as much to do in the dead of winter as there is at the peak of summer. Nevertheless, you will probably have a superior time if you come in the warmer months, either in summer or anytime from May to September. Summers are quite sunny and pleasantly warm for the latitude, with the mercury traveling between 13°C (55°F) and 22°C (71°F) in July in the south and only slightly less up north. Rain is mild in summer and sleety in the long winter.
As well as the reward of warm weather, summer is the time of the midnight sun.
If a winter in Finland is on the schedule try the Baltic-tempered southwest coast temperatures are however freezing but less than around the rest of the country. Winter north of the Arctic Circle is a chilly union of strange bluish light and encroaching melancholy. Despite snowfalls from November, it stays sludgy until late winter: skiing is not great until February, the coldest month, and you can ski in Lapland right through to June.
