Strait of Öresund

The Öresund is an iconic international waterway, and has had great strategic importance and influence on Northern European history throughout the ages. The narrow strait connects the world’s largest inland sea, the Baltic Sea, with the Kattegat. More than 45,000 merchant ships sail through Öresund every year. To this must be added the many fishing cutters, recreational sailors, speedboats and other vessels. This makes Öresund extremely busy.

Despite the heavy shipping traffic, Öresund has a particularly healthy and diverse marine life. There are, among other things, bluefin tuna, porpoises, harbor seals and gray seals. Orca flocks and single individuals are not seen very often, but have been visiting inland Danish waters at regular intervals.

The currents in the Öresund can be fickle, mischievous and strong at times. This happens because of the enormous water flow, which either has a northbound direction from the Baltic Sea to the Kattegat or southbound from the Kattegat to the Baltic Sea. The tidal differences are small in the region (less than 20 cm), but the tide has a visible effect on the current strength in the Öresund. The sea temperature in Öresund can vary between 0 C° (32 F°) in winter and 22 C° (71.6 F°) in summer. The warmest months are in July and August, when you can expect an average sea temperature of 18 C° (64.4 F°). In the colder years, the temperature has been down to about 15 C° (59 F°).

One crossing since 1927

On 31 July 1927, the Danish girl, Edith Jensen, just 17 years old, did what no one thought was possible. She got a lot of attention when she crossed the Öresund on one of the widest stretches. She swam between Barsebäck in Sweden and Bellevue Strand in Denmark (19 km) in 12 hours and 45 minutes. She became the first on this crossing. Since 1927 and until the year 2022, only a few swimmers have crossed one of the widest streaches across the Öresund.

Responsibility and Risk

As a swimmer, you should be aware of the risks and the responsibility connected to marathon swimming. You should never attempt to swim in open water without being aware of the risks connected to your own survival. Thus, marathon swimming requires total dedication.

The main risks associated with marathon swimming include: hypothermia, inadequate training, overconfidence, inexperience, inadequate preparation and lack of understanding of the challenge being undertaken. It is absolutely necessary to train yourself well before committing to marathon swimming. Both physical and mental training are very important.

Marathon swimming is an extreme, high-risk sport. Therefore, it requires the swimmer to be dedicated and engage in continuous training.

As a swimmer, you need a good support team who know you and your limits well, and who can make important and decisive decisions for you while you swim.

The responsibility for your safety lies with you. If you are not ready to swim, do not risk your life or health. It is better to wait and make a new plan for your crossing.
