In summer, Helsinki enjoys up to 19 hours of sunshine a day - and the locals stay outside for most of it. The parks abound with parties and free live music events, and the streets buzz with outdoor cafés, food stalls and concerts. And, if you´re lucky or clever enough to be there for the Juhannus (Midsummer) celebrations, you can experience Finnish festivities at their most exuberant. Kippis!
