Sardinia Sea Temperature 5 Best Things To Know

Are you looking for the perfect vacation destination this year?

Search no more; Sardinia is one of the most beautiful places in Italy, with its warm weather, sandy beaches, and picturesque cliffs. Have you ever wondered what the sea temperature is like in Sardinia?

Sardinia is a Mediterranean region located off the northwestern coast of Italy.

It offers many natural attractions such as beaches, mountains and forests, making it an ideal holiday destination. 

Whether you’re planning to visit Sardinia or just curious about its water temperature to plan your vacation accordingly, this article will provide insights into the average sea temperatures that you should know. 

What Temperature Is The Sardinia Sea?

The warmest months in Sardinia are around July to August. 

During these months, the average sea temperature is around 77 °F, making it perfect for swimming and other water activities. However, during winter months, the sea temperature can drop to as low as 50 °F. 

This means that if you are planning a trip to Sardinia during this time of year, you should be prepared for cooler temperatures and bring appropriate clothing.

In addition to seasonal variations in sea temperature, there are also regional differences. The waters off the western coast tend to be warmer than those on the eastern side due to their proximity to Africa. 

In general, however, Sardinia’s waters remain relatively temperate throughout the year and are suitable for swimming at any time. So if you’re looking for a great place to take a dip or just relax by the beach, then Sardinia is definitely worth considering!

1. Are You Allowed To Swim In The Sea In Sardinia?

The Sardinian Sea is a beautiful destination for beach goers, but unfortunately it is not suitable for swimming throughout the year. During the winter months, the water temperature drops drastically and can become icy cold. 

This makes it virtually impossible to swim in the sea, as well as stay at the beach to sunbathe. The strong northern wind called mistral also makes it difficult to enjoy a day at the beach. 

The tides and waves are often so strong that they can change the shape of the coastline every year, burying or digging up large chunks of sand.

For those who wish to take a dip in Sardinia’s waters, it is recommended to visit during summer, when temperatures are warmer and more pleasant. 

Even then, caution should be taken due to strong currents and unpredictable weather conditions. It is always important to check with local authorities before entering any body of water for safety reasons.

2. What is The Sea Temperature Like Throughout The Year?

The Mediterranean island of Sardinia is known for its beautiful beaches and clear waters.

However, the sea temperature in Sardinia varies throughout the year, making it unsuitable for swimming in the winter months.

The average sea temperature ranges in January and February to July and August.

Although the temperatures may seem warm enough for a swim, there are certain coastal areas which can be colder due to factors such as beach position, amount of daily sunlight, water depth, etc.

For those looking to take a dip in the sea during their stay on Sardinia, it is best to wait until May or June, when the water temperature starts to become more bearable. 

Even then, some locals may find it too cold for their liking and prefer to wait until later in summer before taking a plunge into the refreshing waters of this stunning island.

3. When Is It Ideal To Visit And Enjoy The Sardinia Sea?

Visiting Sardinia is a great way to enjoy the Mediterranean climate and all the attractions it has to offer. From the end of May to the beginning of June, you can expect sunny days with little rain, making it an ideal time for swimming in the sea. 

The warmest water temperatures are usually found between June and August, although this is also when beaches tend to be more crowded. 

For those who don’t mind cooler temperatures, September and early October are still pleasant times to visit, as the sun has kept the water warm for almost four months. 

This is also a great time for those looking for a quieter beach experience as there are fewer people around.

It’s important to remember that although Sardinia may look like a Caribbean island, its climate is completely different, and you can’t swim in the sea throughout the year. 

4. When Does The Sea In Sardinia Begin To Warm Up?

April marks the beginning of Sardinia’s sea warming up again after the winter months. The main temperature jumps, averaging out at 59.54 degrees Fahrenheit, which is similar to what you would find in mid-summer around the British Isles. 

May is when things really start to heat up, with max temperatures.

As a result, May sees an influx of people onto beaches as they take advantage of the warmer weather and test out the waters. 

With long hours of sunshine and pleasant temperatures, it’s no wonder why so many flock to these areas during this time of year! 

5. What Factors Can Alter The Sea’s Temperature In Sardinia?

The sun is the primary factor that affects the temperature of the sea. In Sardinia, the shallow bay is much warmer due to the lack of depth for the sun to have to heat up. 

In addition, currents and winds also play a role in changing the temperature of the sea.

The Best And Worst Months Of The Year To Go To Sardinia


The month of June is a wonderful time of the year, it’s one that we look forward to every year. The days are sunny and long, with temperatures that are warm but not too hot. 

It’s the perfect time to get out and enjoy nature, whether it’s a picnic in the park or a hike. Plus, there’s nothing quite like watching the sun set over the horizon at the end of a beautiful day.


The sea has had all the summer months to warm up by this point, so the water is pleasantly warm enough for swimming. However, in comparison to June, the days are shorter as darkness falls earlier at around 7PM. 

This means that you may need to plan your day accordingly if you want to make the most of your time in Sardinia.

Winter Months (January, December, And February)

These months are not exactly the ideal time for a tourist getaway. Despite the mild temperatures, the windy conditions make it difficult to enjoy outdoor activities. 

Furthermore, most of the restaurants, bars, shops, and tour operators tend to close up shop over the winter months as soon as the tourist masses leave at the end of summer. This means that visitors will find limited services available during these months. 

August And July

July and August are usually the months when people plan their dream holiday to Sardinia, but unfortunately they are one of the worst times. 

Italian families, the moment school finishes, flock to the island amongst international tourists, driving up prices of a visit to the island. 

Final Thoughts

Sardinia is a beautiful island with plenty of things to do and see all year round. The best time to visit depends on what you are looking for in your holiday. 

If you’re looking for a peaceful getaway then winter months may be the best option, while if you want to enjoy the beach and outdoor activities than June or September are ideal.
