Finland: when to go?
continental subarctique climate
Finland offers a subarctic continental climate marked by stark seasonal contrasts. Winter, long and harsh from November to March, sees temperatures plunge well below freezing with permanent snow cover, creating a fairytale landscape conducive to northern lights and Nordic sports. Spring (April-May) remains cool with gradual snow melt. The Finnish summer, brief yet luminous from June to August, reveals all its magic with the midnight sun, pleasant temperatures around 20°C, and lush nature dotted with thousands of lakes. This is the ideal time to discover Helsinki, navigate the archipelago, and enjoy endless summer days. Autumn (September-October) unveils its vibrant colors but temperatures drop rapidly. For a first visit, favor June to August for optimal weather and varied activities.
