The sauna is not reserved for one kind of weather. In Finland it is used all year round, and each season gives the sauna a different character. A summer sauna after a swim feels different from a winter sauna followed by a roll in the snow — but both are wonderful.
Here is how the sauna fits into Finland's four distinct seasons.
Winter sauna
There is nothing quite like a winter sauna. Step from the intense heat of a steaming cabin into the crisp, sharp air of the snow, and the temperature contrast is bracing and gloriously alive. For many Finns, winter is the sauna's most magical season — heat followed by cold air or a plunge, then back inside for another warm round.
Spring and summer
As the ice melts, the sauna moves to the lakeside. The quintessential Finnish summer evening is simple: a sauna, a swim in the lake, and quiet time on the shore as the light lingers late. Birch branches, folded onto the benches as vastat, add fragrance to the steam. It is gentle, social and a little magical in the long dusk.
Autumn and the harvest
As the air turns crisp and the forest changes color, the sauna becomes a warm refuge again. This is the season of the harvest sauna, of steam after a day outdoors, and of the quieter, deeper pleasure of heat as the evenings draw in. The shorter, colder days make the warmth feel more precious than ever.
Sauna all year round
Across all four seasons, the rhythm stays the same: heat, löyly, cooling, rest. The season only decides what the cooling looks like. Finns love the sauna in every weather, which is the whole point — the sauna is made to be enjoyed, not saved for special days.
Frequently asked questions
Can you really go from a hot sauna into the snow?
Yes, and many Finns love it. The cold makes the following heat feel even better. Take it gently the first time, and always have a warm sauna or towel to return to.
What is the best season for a sauna?
There is no best — every season has its appeal. Winter offers the contrast of cold, summer offers lakeside evenings, and spring and autumn offer their own calm. Try all four and pick your favourite.
What is a vasta?
A vasta (or vihta) is a bunch of fresh birch branches, used gently in the sauna. Whisked lightly over the skin it releases fragrance and improves the feeling of the heat. It is a classic summer sauna extra.
