A tall midsummer bonfire burning on the water at dusk in Lappeenranta, its flames doubled in the lake

The country closes and moves to the water. Midsummer Eve is the Friday between 19 and 25 June; the cities empty, a bonfire is lit on every shore at about eleven at night, the sauna is hot, and it never really gets dark.

The Saturday between the 20th and the 26th

Finland fixes this one by law and the Almanac Office of the University of Helsinki, which keeps the state calendar, states it plainly: Midsummer Day, the Day of the Finnish Flag, is the Saturday between 20 and 26 June. Midsummer Eve is the Friday before. The flag rule is unlike any other day of the year — it goes up at six in the evening on Midsummer Eve and is not taken down until nine the following evening, so it flies straight through the shortest night.

The name is not pagan even if the festival is. Juhannus is a form of "John": the feast of Saint John the Baptist falls on or near the solstice, and the Christian name settled on an older celebration of the light. Today it is thoroughly secular.

Where everyone goes

Finns spend Midsummer at a waterside cottage — swim, sauna, and not much else — and the cities empty out in the course of Friday afternoon. Bonfires, kokko, are the old ritual that survived, lit on shores and islands late in the evening, which at that latitude still means daylight. In the Swedish-speaking parts of the country and on Åland the bonfire gives way to a decorated maypole instead.

Helsinki, Tampere and the other large cities now put on public celebrations for the people who stay, and those are the easiest way in for a visitor: a shore, a fire, a stage, and a crowd that looks surprised to be in town.

The statistic

Midsummer is also the weekend on which Finland drowns. Yle, reporting the Finnish Swimming Teaching and Lifesaving Federation's figures, gives an average of six deaths every Midsummer over the past decade; in the country as a whole there are roughly 100 to 150 accidental drownings a year and almost half of the people who drown are intoxicated. The pattern is not dramatic — someone swimming, or moving a rowing boat, or stepping off a dock, usually alone, usually in water they had known since childhood. It is worth knowing before the second sauna.

When it happens

Midsummer Day is the Saturday between 20 and 26 June and is also the Day of the Finnish Flag; Midsummer Eve, the Friday before, is the evening everything happens on. Both are public holidays.

Visiting with respect

Good to know

  • This is a private holiday, spent with family at a cottage. If you are invited to one, that is a real invitation and worth accepting.
  • Sauna first, then the lake, then food. Follow whoever is hosting and do not hurry it.
  • Bring something. Drink, or food for the grill, or both.
  • In the cities the official bonfires are open to everyone and nobody minds an outsider. At a private shore, ask.

Avoid

  • Do not expect shops, restaurants or offices to be open. Most of Finland is shut from Friday afternoon.
  • Do not light your own fire anywhere without the landowner's permission, and never during a wildfire warning.
  • Do not photograph people in or around the sauna.

Stay safe

  • This is the dangerous weekend on the Finnish water. An average of six people drown every Midsummer, and almost half of those who drown in Finland are intoxicated. Keep the drinking and the boat apart.
  • Drownings typically happen while swimming, handling a rowing boat, or after falling off a dock, often alone and in water the person knew well.
  • Mosquitoes in the lakeland in late June are serious. Bring repellent.
  • Public transport thins out drastically over the weekend; check the return before you go.
