Last year, I took a girls’ trip to Sardinia in May, timing it with the bank holiday weekend in Ireland. I’ll be honest, I was a bit nervous we were heading there too early in the season to enjoy the beach. But as it turned out, it was the perfect time to visit. The weather was just right, the beaches weren’t crowded, and we felt like we had the island almost to ourselves. I honestly think May is the best time to experience Sardinia, and I would go back in a heartbeat.

Sardinia is a large Italian island located in the Mediterranean Sea, west of mainland Italy and just south of the French island of Corsica. It’s actually the second-largest island in the Mediterranean after Sicily, with over 1,800 kilometers of stunning coastline and turquoise waters. The island is renowned for its diverse landscapes, from rugged mountains and lush forests to charming rural villages and vibrant cities. With a rich cultural history dating back thousands of years, Sardinia is a stunning and natural paradise.

Absolutely. Sardinia in May strikes the perfect balance: summer is just beginning, but it’s not sweltering hot. The sea is warm enough to swim in, restaurants and beach clubs are open for the season, and yet the island hasn’t been overrun by tourists. Prices for accommodation and flights are lower, and the overall vibe is relaxed and authentic. Long sunny days (sunset is around 8:30 PM) mean you get plenty of daylight to explore, swim, or simply lounge on the beach.

May weather in Sardinia is generally mild and sunny. Expect daytime temperatures between 20–28°C (68–82°F), with average of around 23°C (73°F). Nights are cooler, usually between 12–15°C (53–59°F), which makes for perfect sleeping weather.

Rain is pretty rare—typically only 9 days in the month, with an average of 19 mm. When we visited, we enjoyed three full days of sunshine with a little sprinkle of rain one of the nights. It honestly felt like summer had already begun.

Yes. The sea temperature in May is around 17°C (63°F) on average. Its cool and refreshing, especially when paired with warm sunshine. It was the ideal weather to swim, sunbathe, and enjoy the beach all day without feeling overheated.

There are several festivals in May in Sardinia, and you’ll get to experience a more local side of the island’s culture:

• • Festa di Sant’Efisio (May 1st): A huge religious celebration in Cagliari with traditional costumes, music, dancing, and colorful parades honoring Saint Efisio.

• • Festa di San Simplicio (mid-May): Held in Olbia, this multi-day festival features parades, fireworks, food, and wine in honor of the city’s patron saint.

• • Cavalcata Sarda (second to last Sunday of May): This cultural event in Sassari showcases Sardinian heritage with vibrant costumes, horseback performances, and traditional dances.

One of the biggest advantages of traveling to Sardinia in May is the cost. Because it’s just before the peak tourist season, you’ll find amazing deals on flights and hotels. When I went, I was able to book a hotel with beach access for a fraction of its usual summer price. Many properties are still trying to fill rooms during the month of May, so you’re more likely to land a prime location without blowing your budget.

If you prefer peaceful travel experiences over busy tourist hotspots, May is your month. Sardinia feels calm and uncrowded, most visitors are locals, and you won’t need to fight for a table at popular restaurants or a spot at the beach. It’s not deserted, but it has a laid-back, tranquil vibe that makes it incredibly relaxing.

You’ll enjoy long, sunny days that are warm but not sweltering. It’s the kind of weather that invites you to stay outside all day, swimming, hiking, exploring coastal towns, or just enjoying a long lunch by the sea. Evenings bring a pleasant breeze, making it ideal for strolling around or enjoying a drink on a terrace.

While Sardinia in May offers plenty of perks, it’s worth being aware of a few small drawbacks, none of which should be deal breakers, but helpful to know when planning your trip.

Sardinia is a seasonal destination, especially in smaller towns. Some hotels, restaurants, and attractions only open during the peak summer months, or may run on limited hours in May; like opening only on weekends. When I visited, this didn’t affect our plans at all, but it’s something to keep in mind. If there’s a specific spot you’re excited to check out, I’d recommend confirming their opening hours before your trip.

May tends to be quite dry, but occasional showers can happen. On average, there are about 9 days of rain throughout the month, though this varies from year to year. During our trip, we only experienced a bit of nighttime rain, and the days stayed sunny and bright. Compared to the wetter winter and early spring months, Sardinia in May still feels like a solid bet for good weather, but it’s not quite as dry as high summer.

Sardinia is famous for its beaches, and May is a fantastic time to enjoy them. With crystal-clear water and fewer people, you can unwind without the crowds. Some standout beaches to visit include Cala Goloritzé, La Pelosa, Su Giudeu, and Porto Giunco. Many beaches offer umbrella and sunbed rentals, or you can spend the day at a beach club with access to food, drinks, and a comfortable setup by the water.

If you enjoy cycling, renting a bike is a fun and active way to explore. Many hotels and beach clubs offer hourly or daily rentals. You can ride through coastal paths, discover hidden beaches, or explore charming towns at your own pace.

Even if you’re in Sardinia mainly for the beach, I would recommend taking a few hours to explore some of the towns. They’re full of character, history, and beautiful architecture. Here are a few I would recommend.

• • Alghero (Northwest): Known for its preserved old town and Catalan influence.

• • Bosa (Northwest, south of Alghero): A colorful town along the river, full of charm.

• • Castelsardo (North): A hilltop town with a medieval castle and panoramic sea views.

Sardinia is rich in history, and you’ll find fascinating archaeological sites scattered across the island. In Cagliari and Cabras, you can explore archaeology museums that offer deeper insight into the island’s ancient past. One of Sardinia’s most unique features is its nuraghes; mysterious megalithic stone towers built during the Nuragic Age, found nowhere else in the world. The most famous of these, Su Nuraxi, is especially worth visiting. The island also has well-preserved Roman ruins, medieval city walls, ancient fortresses, and beautiful mosaics that offer a glimpse into the many civilizations that once called Sardinia home. 

Sardinia’s rocky peaks and coastal cliffs make it a perfect destination for hikers. In May, the weather is ideal; sunny but not too hot, with long daylight hours. Whether you’re a seasoned hiker or just looking for a scenic walk, there’s a trail for you. Some popular hikes include: Gennargentu National Park for mountain trails, Gola di Gorropu, one of the deepest canyons in Europe, and Cala Fuili to Cala Luna, a coastal hike with epic views.

Exploring Sardinia by boat is a must. The coastline is stunning, and many boat tours offer stops for swimming, snorkeling, or visiting hidden coves. I took a small-group tour near Alghero with just five people. We spent the morning cruising along the coast, exploring sea caves, and snorkeling in secluded bays. It was one of the highlights of the trip.

Yes, Sardinia is an island, but it’s surrounded by smaller, equally beautiful ones worth exploring. These islands are great additions to your Sardinia itinerary, especially if you’re looking to escape even further from the beaten path.

• • Asinara Island: A protected national park known for its wildlife, including rare white donkeys.

• • La Maddalena Archipelago: Rugged, rocky islands with dramatic cliffs, perfect for a boat tour or beach-hopping.

• • Sant’Antioco: Offers stunning coastal scenery, ancient churches, and an archaeological museum.

You’ll definitely want your swimsuit! May is warm enough to enjoy the water, so pack for sunshine. Include light, breathable clothes like t-shirts, tank tops, shorts, and sundresses. Evenings can get breezy, so bring a light sweater or jacket for dinners or sunset strolls.

If you’re planning to explore the island or do any hiking, pack comfortable walking shoes or lightweight trainers. A sunhat, sunglasses, and reef-safe sunscreen are must-haves for long days in the sun. A reusable water bottle is also a good idea, especially if you’re out exploring all day.

For boat excursions or day trips, a small backpack or tote bag is useful to carry your essentials, and a light scarf or cover-up is great for layering if the wind picks up on the water.

Trust me, Sardinia in May is as good as it gets. You get beautiful weather, affordable prices, and a much more relaxed vibe before the summer crowds roll in. Whether you want a quiet beach holiday, an active adventure, or a little bit of everything, Sardinia delivers. It’s one of those destinations you’ll fall in love with. If it’s not already on your travel list, it should be. May is the perfect time to experience the island’s charm, whether you’re exploring with friends, a partner, or heading off on a solo trip.
