The archaeological remains found here will take you back in time to the epic naval battles between ancient peoples for the domination of the seas; marble slabs, columns, wood, anchors, these extraordinary underwater museums are one of the things that make diving in Sardinia so special.

And with numerous shipwrecks still equipped for battle, armed with cannons and guns loaded with ammunition, supplies that never reached their destination, the seabeds around Sardinia are a unique insight into this region’s rich history.

When To Go Scuba Diving In Sardinia

With hot, dry summers and cooler yet humid winters, Sardinia experiences a typical Mediterranean climate. You can dive all year round in Sardinia but conditions are best during the summer months. 

Although the water can still be a little cool, May is arguably the absolute best time to go scuba diving in Sardinia. The prices are reasonable, the dive sites are relatively quiet and the visibility is excellent, up to 40m most days.

Summer (April – September)

During the summer season, water temperatures can reach 26°C (82°F) but there is normally a thermocline at around 12m (40 ft) where the temperature will drop down to 15°C (59°F). 

July and August are considered the peak season in Sardinia when accommodation prices often double and dive sites can be very busy. So it’s better to avoid these months if possible.

Visibility is best at the beginning of the summer, in May and June, but the water can still be quite cold. The sea is warmest towards the end of the season in September and October, but thunderstorms are more likely. 

Winter (October – March)

In the winter, water temperatures remain around 12°C (54°F), visibility is reduced and a lot of the marine life disappears. So it’s best to avoid this time of year. 

But if you’re looking for a cheap deal on diving and accommodation, consider visiting at the start or end of this season when conditions are still good and prices are low.

Where To Stay When Scuba Diving In Sardinia

Although Sardinia is relatively easy to travel around it’s still one of the largest islands in the Mediterranean so it makes sense to stay in or near the areas you want to dive in. Sardinia offers a wide range of accommodation options to suit all budgets including hostels, hotels and full-service resorts. 

If you only have 1 week, we recommend picking one area, for example, Costa Paradiso in the North, where you can enjoy both the Asinara and La Maddalena Marine parks. Or you could try basing yourself in Villasimius in the South if you want to be able to access Capo Carbonara and the wrecks in the Gulf of Cagliari.

Or if you’re looking for a more relaxed setting and untouched dive sites, consider a stay in the relatively undeveloped and beautiful area of Sant’antioco to enjoy the lesser-known, but equally impressive, dive spots on the west coast.

But if you have more time, we really do recommend staying in a few different areas to really make the most of the variety of scuba diving in Sardinia.

The History Of Sardinia

Contrary to the island’s clear waters, the historical origins of Sardinia remain somewhat murky. While no written records remain of the original settlers, it’s suggested that the island received its name from Sherden, a group of sea pirates who engaged in coastal raiding.

The island of Sardinia features several Narughi, ancient structures made of basalt taken from extinct volcanoes during ancient times. While the exact origins of who made these structures are unknown, historians generally attribute the construction of these structures to the island’s prehistoric population.

The Narughic age is recorded in history as having existed during the period of 1900-730 BCE. In today’s age, the Narughe has become a symbol of Sardinia’s unique history and culture dating back to ancient times. Archaeologist’s believe there were more than 10,000 Narughe structures, although only 7,000 are officially recorded.

Organized tribal states continued to establish a culture and population in Sardinia. Sardinian mines attracted the attention of Phoenician traders who established trading posts on the island. 

The Greeks attempted colonization of Sardinia in the early part of the 6th century. This effort proved unsuccessful due to opposition from the aforementioned Phoenicians. Before the city of Carthage gained ruling power over the Western Phoenician’s, the indigenious people of Sardinia and the settler’s of the island co-existed in a peaceful manner.

After Carthage gained ruling power, there was a struggle for power and control in the West which led to Carthaginians launching a conquest over the island’s most economically productive areas. This military conquest occurred around 500 BCE and led to Sardinia’s native population relocating to the island’s mountains. After the capture of Sardinia by the Carthagianians, the ruling hands of the island changed many times. 

In the year of 238 BCE, The Romans took control of Sardinia during a Carthagian revolt. The native population of Sardinia continued to face a tragic history as they were conquered by the Roman’s after several bloody Roman campaigns.

Following the Roman’s, Vandal and Byzantine populations. The Vandal ruling period of Sardinia is characterized by its cultural revival through the assembly of monasteries and relics of St. Augustine. In 533-534, Byzantine Duke Cyril conquered the Vandals. The date of Sardinia’s separation from the Byzantine empire remains unknown to historians. 

Following the Byzantine Empire rule of Sardinia, Italian and Arab influence pervaded the island. The Island’s violent history continued through repeated conflicted with Aragonese, Austrian, and Savoyian domination before being united with Italy in 1861 under King Victor Emanuel II.

The prolongment of Sardinia being unified with Italy can be attributed to its geographical isolation from the Italian mainland as well as its distinct language. 

Sardinia pushed forward, fighting for autonomy during World War I, only to be fought with opposition from Mussolini’s fascist party. Sardinia served as an airbase for Mediterranean attacks during World War II. Following World War II in 1948, Sardinia gained autonomy while still remaining a region of Italy.

Sardinia makes a fantastic location to visit partly due to the island people’s strict code of honor that is characterized by loyalty, as well as hospitality. Sardinia’s population is heavily coast concentrated providing opportunities for tourist markets and a growing economy.

If you’re looking to skip the crowds,Sardinia may be the destination for you and your scuba excursion as it is one of Italy’s least populated regions. On the coast, you’ll find rich opportunities to indulge in the region’s seafood as Sardinia’s waters are known for lobsters, tuna and sardines.
