Summer in the city: An open-air pool beckons in the heart of Helsinki

Helsinki Swimming Stadium is an oasis. In a park in the middle of the Finnish capital, you can swim in a heated, Olympic-size outdoor pool or work out at an open-air gym.

Every year it happens all over again, typically on the second Sunday in May. At 4 am, people are already lining up at the entrance. After more than six months, you can finally use the 50-metre (55-yard) outdoor pool again, not to mention the sauna.

Helsinki Swimming Stadium’s faithful customers are eager to be among the first to jump into the water.

Located near the centre of Helsinki, the pool is open from early May to mid-September (during corona restrictions the season has been several weeks shorter). The pool is open every day from early morning to late evening, except for adjusted opening hours on Midsummer’s Eve and Midsummer Day.

Many people go to the Swimming Stadium to spend a summer day in a beautiful location where the clear water, green lawn and leafy trees create a refreshing haven in the heart of the city. A modest admission fee gives you unlimited access to the swimming pool, gym, sauna, deckchairs and waterslide.

Visitors come even when the weather is cool or rainy – the large pool is heated to 27 degrees Celsius (80 Fahrenheit), and the children’s pool is even warmer. After swimming, you can have a sauna. There are two; one is moderately hot and the other is much hotter.

At 2.5 kilometres (1.5 miles) from Helsinki Central Railway Station, the Swimming Stadium is within easy reach on foot or by tram. You can also opt for a city bike, purchasing a daily, weekly or seasonal pass – there are bike stations all over the city, including one near the pool.

More than just a pool

The Swimming Stadium forms a venue for aquatic sports and more. There’s a sports field, an indoor gym, a table-tennis table, two beach volleyball courts, a basketball court and a waterslide. Don’t forget the café and the ice cream stand.

The main attraction, of course, is the 50-metre swimming pool, with separate lanes for swimmers of different skill levels and a wide lane for aqua jogging. Facilities also include a children’s pool, a wading pool and a diving pool with springboards at 1 and 3 metres (3 and 10 feet) and platforms at 5, 7.5 and 10 metres (16, 24 and 32 feet). Aqua jogging vests and various other accessories are available free of charge.

The pool also hosts water aerobics and swimming lessons for adults and children, and water polo teams practice there. In the spring and fall, Helsinki schools hold physical education classes in the Swimming Stadium. Now and then, triathlon competitions and theatre performances are held there.

The loudspeakers usually play the radio, sometimes interrupted by service announcements in four languages: Finnish and Swedish, which are official languages in Finland, as well as English and Russian.

Admission to the Swimming Stadium costs just a few euros, much less than a private pool or waterpark. For current prices, visit the Swimming Stadium website. Children from 7 to 17 years old, students, unemployed persons, pensioners and people with disabilities receive a discount, and entrance is free for kids under seven.

The entrance fee covers only a small portion of the operating costs. The City of Helsinki covers the rest, seeing it as a way to promote a healthy lifestyle. Other municipal sports organisations, including indoor pools and gyms, are funded in the same way, as is the city bike programme.

Other Finnish cities, such as Espoo, Turku, Tampere and Porvoo, have similar open-air swimming pools. The Olympic-size pool in Lahti, 100 kilometres (60 miles) north of Helsinki, may boast the oddest location – it’s at the bottom of a ski jump (link in English).

June and July are the time of white nights in Helsinki, when the sun sets but the sky doesn’t get completely dark. By late summer, dusk falls earlier in the evening, and the outdoor pool season ends in mid-September. On the last Friday of the season, they hold a moonlight swim, keeping the pool open almost until midnight, with lanterns and live music. Visitors say goodbye to their summer oasis until next year and switch to indoor pools.

A jewel of Finnish functionalist architecture

Helsinki is home to many swimming pools, including four outdoor pools in the metropolitan area. The most popular and iconic one is Helsinki Swimming Stadium. Architect Jorma Järvi designed it for the 1940 Olympic Games, which were cancelled because of the Second World War. During the war, people used the pool basins to store root vegetables and herring.

The venue was completed in 1947 and Helsinki hosted the Summer Olympics in 1952. A special set of stands nicknamed the sun stands was built for the Olympics. Today, visitors can spread out their towels there for sunbathing.

The creators of the sports complex paid a lot of attention to detail. The functionalist style of the time is visible in the light fixtures, staircases and loudspeakers. Historical photos decorate the doors of the spacious locker rooms.

Next to the Swimming Stadium is another prominent example of functionalism, Helsinki Olympic Stadium, renovated in 2020. It houses a café, a new sports museum and a tower that offers a view over the entire city.
