Can You Swim in the Baltic Sea?

The short answer is yes. But the long answer involves a little more explanation.

The Baltic Sea is a popular tourist destination. The sea is dotted with islands, and its coastlines are dotted with beaches. But it’s not just the scenery that draws people to the Baltic Sea; it’s also the water. The temperature of the water can be quite nice for swimming in the summer months if you’re careful.

However, there are no sandy beaches on the shores of the Baltic Sea, and it can get quite chilly. But if you’re willing to brave some chilly water (and maybe even get your feet wet), then there are plenty of places where you can enjoy a dip in this beautiful part of Europe.

Is the Baltic Sea Warm Enough to Swim?

The Baltic Sea is known to be cold and dangerous in the non-summer months. It’s certainly not warm enough to swim year-round — even in July or August. But many people swim in it anyway. In fact, there are several islands where people come from all over Europe to enjoy their time in the water.

If you want to swim in the Baltic Sea, there are some things to consider before taking a dip in it. First, there isn’t much sand on most beaches because of erosion from wind and waves — so don’t expect soft sand under your feet while you’re swimming around! Second, there are often sharp rocks hidden just below the surface of the water — so watch out for them! Third, even though it’s warm enough to swim in during the summer, there may still be ice floating around out there, especially if you go further north into Scandinavia or Russia.

Best Locations for Swimming in the Baltic Sea?

The Baltic Sea is a unique aquatic environment, with a brackish water salinity level of 1.8-2.2%. This makes it much less salty than the surrounding oceans and seas but more saline than freshwater lakes and rivers.

This combination of features calms the Baltic Sea, allowing for safe and enjoyable swimming. The best places for swimming in the Baltic Sea are:

Jurmala, Latvia

The city of Jurmala is located on the shore of the Baltic Sea in Latvia. It is one of the most popular tourist destinations in this country and has a rich history. The beach of Jurmala is a beautiful sandy beach that stretches for miles on either side of the city. Many hotels and hostels in this area offer cheap accommodation to tourists who wish to explore this beautiful place. In addition, the beach here is clean and safe for swimming during all seasons of the year.

Curonian Spit, Lithuania

The Curonian Spit is a 65km-long sandbar located between the Curonian Lagoon and the Baltic Sea. It’s one of the most beautiful places in Lithuania, where you can swim or sunbathe on beautiful sandy beaches. The best time to visit this destination is from May to October when there is no ice in the sea.

Aland Islands, Finland

The Aland Islands are an archipelago of over 6500 islands off the coast of Finland in the Baltic Sea. There are several islands with sandy beaches that are great for swimming and relaxing on holiday. The best time to visit this destination is between June and August when there is no ice in the sea.

Rugen, Germany

The island of Rugen is a popular destination for tourists and locals alike. With its beautiful beaches and charming towns, it’s no wonder this island is a popular spot for swimming. The water here is very clean, and there are many options for water sports on the island. In addition, you can rent bikes or take tours around the island by boat or by foot. You’ll also find great restaurants on this island as well as shopping areas if you need to get something new to wear after your swim in the Baltic Sea!

Parnu, Estonia

One of the best places for swimming in the Baltic Sea is Parnu, Estonia. The city has a long sandy beach with clear water and wonderful views. The area is known as one of the best places for water sports lovers. You can find many different water activities, such as windsurfing, jet skiing, kayaking, parasailing and many others.

Mon, Denmark

The town of Mon has a beautiful beach with white sand and crystal-clear water. It is a great place to enjoy swimming and sunbathing during the summer months. The beach is located near the village of Hvide Sande, which offers great opportunities for hiking in nature and looking at wildlife such as seals or deer.

What is Wrong with the Baltic Sea?

The Baltic Sea is an incredible place to visit. The beaches are beautiful, the people are friendly, and the cities are full of things to do. But there’s one thing you might not know about this area: You can’t swim in it at all times throughout the year.

The Baltic Sea is a salty body of water that is connected to the North Sea and Atlantic Ocean through the Kattegat and Skaggerak straits. The salinity levels of this lake vary throughout the year, but they are generally between 0.5-1%. This may not seem like much, but it’s enough to make it impossible for humans to float on top of the water! If you tried, your body would sink like a stone. This is because when your body absorbs water through your skin, it becomes heavier than air (just like when you get wet). This means that your lungs will quickly fill up with water if you try to swim in this part of the world!

In addition, some parts of the Baltic Sea have been heavily polluted over time by industrial waste and agricultural runoff from surrounding countries like Germany and Poland. There are also concerns about contamination from nuclear power plants along its shores and oil spills from tankers.

Swimming in this body of water is dangerous because it could cause serious health problems for anyone who does so. It’s also illegal to swim here because the Baltic Sea is a protected nature reserve under European law — but there are still plenty of ways to enjoy this beautiful region without getting into trouble!

When Is it a Risk to Swim in the Baltic Sea?

Although many people enjoy swimming in the Baltic Sea, it’s important to know that there are risks associated with this activity. The combination of warm water and many microorganisms can cause serious infections in people who swim in the sea without taking precautions.

During heat waves, there is an increased risk of vibrio bacteria infections due to higher water temperatures. Vibrio bacteria can cause severe illness if consumed by humans; however, if ingested through the skin, it may cause milder symptoms such as fever and vomiting. If you have been swimming recently and feel ill afterward, please consult your doctor immediately!

The best way to avoid infection from vibrio bacteria is by following these tips:

  • Always swim within designated areas (marked by buoys) where water quality is monitored regularly by local authorities;
  • Avoid contact with open wounds or cuts while swimming;
  • Avoid swallowing seawater and rinse your mouth thoroughly after being exposed to seawater;

What Sea Animals threaten the Bathers at the Baltic Sea?

The Baltic Sea is home to more than 1,000 species of marine life, including whales, dolphins, and seals. It also has some of the largest populations of grey seals on Earth. Unfortunately for swimmers who love to take dips in the sea, many dangers are lurking below the surface that can harm bathers if they aren’t careful. These include the following:

Weever Fish

The weever fish is a venomous species of fish that can cause severe pain and tissue damage if stepped on. The venom is injected by spines in the dorsal and anal fins, which break off in the wound, causing additional pain for days after the initial injury.

The venom contains proteolytic enzymes, similar to snake venoms, which break down proteins in muscle tissue. The most common symptom is intense pain at the site of injury; other symptoms include nausea, vomiting, sweating, and chills.


The Jellyfish come in different colors, sizes, and shapes, but all have one thing in common – they can cause painful stings on human skin when contact with them occurs. Jellyfish stings are particularly dangerous for bathers who wear contact lenses because they can cause severe eye irritation and temporary blindness if not treated immediately after exposure to jellyfish venom.

Does it Get Rough at the Baltic Sea?

The sea is shallow, with an average depth of only 1.5 meters and a maximum of 7 meters (and that’s not far from shore). This means that at times even if you don’t venture too far out, it may be difficult to stand up because of the waves crashing over your head. The wind makes things even worse – when it blows hard, it can create some waves that are more than 2 meters high!


Contrary to what many travel guides and other publications say, you can swim in the Baltic Sea. But it’s not recommended by most people who know the area. Also, you should always watch out for dangerous currents. The best thing to do is to know the water temperature before entering the water, avoid bad weather and strong winds, swim with a partner, watch out for slippery rocks near the shore, and don’t swim when the seaweed is high.
