The best time to visit Finland depends on the type of experience you are after, and where you are headed. The summer months between June and August bring warm weather, which never reaches a stifling heat, and is the perfect time to visit the south. Be aware that if you decide to travel to Lapland in July, mosquitoes abound in numbers, so insect repellent is a must.
Winter in Finland can begin in November and end in April, depending on the location. These months are perfect for winter activities in Lapland; and the lead up to Christmas is prime-time for those wanting to visit the ‘home’ of Santa Claus.
Finally, autumn during September brings amazing scenery in all areas, through attractions will have shorter opening hours.
The capital of Helsinki is a year-round destination.
