The Republic of Croatia is located on the eastern coast of the Adriatic Sea, which is favorable for swimming during half of the year. The sea temperature in Croatia begins to exceed 20 degrees Celsius (68 degrees Fahrenheit) starting from the month of May and maintains this temperature until September. The sea temperature in Croatia is suitable for swimming even in the months of April and October, when it ranges between 16 and 18 degrees Celsius (61-64 degrees Fahrenheit). The sea temperature in Croatia is systematically recorded and monitored at over a hundred locations.
The temperature is perfect for swimming for all ages.
The temperature of the sea in Croatia is interesting for study and has been systematically recorded and monitored for over 30 years. The Adriatic Sea is a warm sea. During summer, the surface temperature of the open sea in Croatia ranges from 23 to 25 degrees Celsius (73.4 to 77 degrees Fahrenheit), while the deepest waters have a temperature greater than 11 to 13 degrees Celsius (51.8 to 55.4 degrees Fahrenheit). In general, the temperature of the sea in Croatia decreases from the surface towards the bottom. Temperatures are slightly higher near the coast, especially in shallow and enclosed bays. During the warm part of the year, especially in summer, there is a temperature jump in the layer from 10 to 30 meters from the surface, and it decreases the fastest at a depth of several meters. At a depth of 70 meters, the temperature of the sea in Croatia is 18 to 19 degrees Celsius (64.4 to 66.2 degrees Fahrenheit).
During the fall, the sea in Croatia begins to cool on the surface. In winter, the surface temperature of the sea in Croatia varies from 14 to 16 degrees Celsius (57.2 to 60.8 degrees Fahrenheit), with a minimum of around 12 to 10 degrees Celsius (53.6 to 50 degrees Fahrenheit). In winter, the southern Adriatic is warmer than the northern, and the temperature difference between the northern and southern Adriatic is 8 to 10 degrees Celsius (46.4 to 50 degrees Fahrenheit). The shallow waters of the northern Adriatic, ports, bays, and river estuaries cool down to 4 to 6°C (39.2 to 42.8 degrees Fahrenheit) in winter. There is no sea ice in the Adriatic Sea. In spring, the sea begins to warm up and soon reaches a temperature of 18 to 22 degrees Celsius (64.4 to 71.6 degrees Fahrenheit) suitable for swimming. During summer, the sea in Croatia is the warmest. The maximum temperatures occur in July and last until mid-September, ranging from 23 to 26 degrees Celsius (73.4 to 78.8 degrees Fahrenheit). During summer, the sea is cooler than the air, preventing significant warming, while in winter, the sea is warmer than the air and warms it up. Thus, the sea in Croatia acts as a regulator of air temperature, mitigating temperature extremes in summer and winter.
The coastal zone, especially near mountainous areas, is rich in underwater sources of fresh water called “vruljas”. Famous vruljas are located along the coast in the Velebit and Brac channels, Rijeka, Kastela, Mali Ston, Boka Kotorska Bay, and Velika Vrata. In summer, relatively cold water flows from these sources and quickly mixes with seawater. However, under certain meteorological conditions, fog can form in these areas. During summer, the cold “bura” wind can quickly cool the surface layer of the sea, keeping the sea temperature 2 to 4 degrees Celsius (35.6 to 39.2 degrees Fahrenheit) lower as long as the bura is blowing. The temperature of the sea in Croatia is measured daily at over one hundred locations along the Croatian coast. The temperature of the sea in Dalmatia, the temperature of the sea in Istria, and the temperature of the sea in Kvarner have their peculiarities and together help illustrate the complex picture of the sea temperature in the Republic of Croatia.
Although technically you can bathe at any temperature, which is why some recommend bathing in cold water for various health benefits, the best temperature to bathe at is between 20 and 23°C. For most bathers, this is the ideal temperature, especially because it reduces the chance of shock in older and sick people.
For babies from 0 to 3 months, the minimum temperature at which they should be bathed is 32°C. For those from 3 to 12 months, the temperature can be slightly lower - 30°C. For older children, the temperature should be around 25°C. The temperature of any baby bath should never exceed 35°C.
The most famous beaches in Croatia are Zlatni Rat in Bol on the island of Brač, Zlatna Plaža in Lopar on the island of Rab, Sakarun Beach on Dugi Otok, Stiniva Beach on the island of Vis, Banje Beach in Dubrovnik, and Bačvice Beach in Split.
It is very simple to protect yourself from the sun, just make sure to drink enough water, use sunscreen with a high factor (30+) and avoid the sun when UV radiation and temperature are at their highest, which is from 10 in the morning to 4 in the afternoon.
