Tyrrhenian Sea Water Temperature Today & Regional Overview
We find every place where you can swim and show you the water temperature there today and throughout the year.
Current Water Temperature
The water temperature in the Tyrrhenian Sea today ranges from 21.3°C (Capo Coda Cavallo, Italy) to 24.5°C (Sant'Agata di Militello, Italy).
As of today, the minimum water temperature in the Tyrrhenian Sea ranges from 68°F (20°C) to 74°F (23°C). The water is warm and pleasant for swimming, and in this range, one can stay in the water for extended periods without the risk of hypothermia. This is the ideal temperature for relaxation, swimming, and water sports. Families with children, as well as outdoor enthusiasts, will enjoy swimming and time spent in the water. For most people, this is the optimal temperature for a comfortable beach experience.
It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

The Tyrrhenian Sea, off Italy’s western coast between the mainland, Corsica and Sardinia, shows a clear seasonal cycle in surface water temperature. In winter (December–February) typical temperatures range from about 12 °C to 15 °C along most coastal areas, rising in spring (March–May) to roughly 14 °C–20 °C. Summer (June–August) brings the warmest waters, generally between 20 °C and 26 °C, with shallow, sheltered bays and southern exposures occasionally reaching toward 26 °C–28 °C on calm, sunny stretches. In autumn (September–November) the sea cools again, usually ranging from about 18 °C to 22 °C as the season progresses. Local factors such as depth, coastal configuration and prevailing winds can shift these values by a few degrees between nearby beaches.
Swimming Conditions
Swimming in the Tyrrhenian Sea is commonly practiced and effectively permitted year-round, with the most comfortable and popular period in summer when surface temperatures are warm enough for extended bathing without thermal protection. Spring and autumn are also suitable for many swimmers, though water at the lower end of those ranges can feel brisk and may require shorter sessions or a wetsuit for those sensitive to cold. Winter swimming is possible but limited by colder temperatures, and prolonged immersion at 12–15 °C carries risk of rapid cooling. As always, local conditions—weather, currents, water quality and presence of lifeguards—should be checked before entering the water.
