Is September a good time to visit Sardinia? September is genuinely the best month to visit Sardinia. The sea is at its warmest, averaging 24 to 26°C (75 to 79°F), the Italian and European families have returned home for the school year; prices drop noticeably; and the island feels calm without feeling closed. It is also the last month when full-boat tour schedules are running to the La Maddalena Archipelago and other island destinations, so if boat trips are on your list, September is your window.
Key Takeaways
- September is the best month to visit Sardinia: warm sea, far fewer crowds, lower prices.
- It is the last month for full-boat tour schedules to the La Maddalena Archipelago. Book early.
- You need a rental car. Book it before you travel, not at the airport.
- Some beaches require reservations and paid entry, even in September.
- The Autunno in Barbagia festival begins in September, offering a rare look at inland Sardinian culture.
Why Sardinia in September Is the Best Month for Sardinia
Ask anyone who has been to Sardinia more than once and they will tell you the same thing: go in September. The tourists who come in July and August crowd the best beaches, pay peak prices for accommodation, and spend hours stuck in parking lot queues. September visitors get the same water, the same scenery, and the same beaches, but with a fraction of the stress.
The sea temperature in September typically sits between 24 and 26°C, which is actually slightly warmer than July since the ocean takes time to heat up through summer. Air temperatures during the day hover around 26 to 28°C, comfortable without the aggressive heat of August. Evenings are pleasant, and you will want a light layer when sitting outside after dinner.
There is another reason September is particularly special: it is the last full month for boat tours to the La Maddalena Archipelago and other offshore destinations. Most tour operators wind down through October, so if you want to take a full-day boat excursion to the islands, September is your best and last reliable window. This matters more than most guides acknowledge. The archipelago beaches that cannot be reached any other way are genuinely among the most beautiful places in the Mediterranean.
Feuza’s Take: “We went to Sardinia in September and it genuinely changed how I think about travel timing. We flew into Olbia, picked up our car with Smeralda car rental, and drove down to San Teodoro. The region was busy enough to feel alive, but nothing like what I saw in photos from August. Parking at the beaches was easy, the water was incredible, and we got to do the Le Hemingway boat tour to La Maddalena without fighting for spots. September in Sardinia is the kind of trip where everything works the way it was supposed to.”
Weather in Sardinia in September
September in Sardinia is part of the extended Mediterranean summer. The first three weeks are reliably warm and mostly sunny. Rain becomes more likely in the final week of September, though it is usually brief and does not derail a trip. Here is what to expect:
| Metric | Early September | Late September |
|---|---|---|
| Average daytime temp | 27 to 29°C (80 to 84°F) | 24 to 26°C (75 to 79°F) |
| Sea temperature | 25 to 27°C (77 to 81°F) | 23 to 25°C (73 to 77°F) |
| Average rain days | 2 to 3 | 4 to 5 |
| Sunshine hours/day | 9 to 10 | 7 to 8 |
The sea temperature is genuinely ideal for swimming throughout September. Most visitors find it more comfortable than June, when the water can still carry the cool of winter. Pack light summer clothes, a light jacket for evenings, and sunscreen. UV levels remain high.
Getting There: Flying Into Olbia and Renting a Car
For northern Sardinia, Olbia Costa Smeralda Airport (OLB) is the right arrival point. It sits about 25 km north of Olbia town and roughly 40 km north of San Teodoro, which is the best base for the northeast coast. Multiple airlines serve Olbia from major European cities, with the most connections in summer and early fall.
A rental car is not optional in Sardinia. Public transportation exists between towns but does not reach most beaches, and the island’s layout makes a car essential for exploring. Book your rental well in advance, especially for September when demand is still significant. Several rental companies are operating from Olbia Airport, and if you want a local operator with good service in the San Teodoro area, Smeralda Car Rental is worth considering.
Feuza’s Take: “We rented with Smeralda and it worked well for our trip. One thing I cannot stress enough: book the car before you leave home, not when you land at Olbia. Airport car rental desks in Sardinia can have long waits, and in peak season or early fall, availability gets tight. We have a whole guide to Sardinia’s airports that covers what to watch out for, including what happens when late-night arrivals meet closed car rental counters.”
Where to Stay in Sardinia in September
September prices are noticeably lower than July and August, which opens up options that might be out of reach in peak season. Here are the main areas to consider for a September trip to northern Sardinia:
San Teodoro
San Teodoro is the best all-around base for the northeast coast. The town has good restaurants, a lively but not overwhelming atmosphere in September, and easy access to several of the best beaches in northern Sardinia. La Cinta, Cala Brandinchi, and Lu Impostu are all within a short drive. From here you can also reach Palau for the La Maddalena ferry, and Costa Smeralda is accessible as a day trip. Accommodation ranges from small apartments to larger resort-style hotels.
Palau
Palau is the departure point for La Maddalena ferries and has its own relaxed seaside character. Staying here puts you closest to the archipelago and makes early morning departures for boat tours easy. It is smaller and quieter than San Teodoro, which suits travelers who want a calmer base with easy island access.
Olbia
Olbia is a practical base rather than a scenic one, but it has good accommodation options at lower prices and puts you centrally located for day trips in multiple directions. If you are splitting time between Costa Smeralda, San Teodoro, and La Maddalena, Olbia can work well as a midpoint.
Boat Tours and La Maddalena Archipelago
This is the single most important activity consideration for a September visit. The La Maddalena Archipelago is a national park comprising over 60 islands off the northeastern tip of Sardinia. The water here is some of the clearest in the entire Mediterranean, and the only way to reach the best beaches is by boat. Full boat tour schedules run reliably through September. By late October, most operators have reduced or stopped.
Day boat tours typically depart from Palau or La Maddalena town and cover multiple stops around the archipelago, including island beaches, snorkeling spots, and sometimes a pass by Spiaggia Rosa on Budelli Island (which cannot be landed on but is visible from the water). Most full-day tours include lunch on board or at anchor, and depart around 9 AM returning by early evening.
One operator worth knowing is L’Hemingway, which offers full-day excursions in the archipelago with a genuine focus on the experience rather than packing in maximum numbers. The boat makes stops at some of the most pristine spots in the park, and lunch is served on board. They run through September and it is worth booking in advance, as the remaining spaces fill up quickly once August visitors leave and September travelers arrive.
Feuza’s Take: “The Le Hemingway boat tour was a genuine highlight of our trip. We did it in September and I am really glad we did not leave it until October. The crew was wonderful, the stops were beautiful, and having lunch on the water in the archipelago is the kind of thing you remember for years. Book this early: September tours do fill up, especially earlier in the month when there are still many visitors on the island. It is worth calling or emailing ahead rather than assuming you can book last minute.”
Beaches in September
Sardinia’s beaches in September are at their most enjoyable. The water is warm, the crowds have thinned significantly, and the late summer light makes everything look extraordinary. Several important things to know before you go:
Pre-Booking and Reservation Requirements
Some of Sardinia’s most beautiful beaches have strict daily visitor caps and require advance reservations with a fee. This is still true in September, though the spots are easier to get than in July or August. The main beaches with reservation systems are:
- La Pelosa (Stintino): Daily cap of 1,400 visitors, split into morning and afternoon slots. Fee of €3.50 per person. Book at spiaggialapelosa.it. Available year-round for dates up to October 15.
- Cala Coticcio (La Maddalena): Only 60 people per day allowed. Fee of €3 per person. Book through the national park authority’s website. One of the most pristine beaches in Europe.
- Cala Brigantina (La Maddalena): Also 60 people per day, €3 per person. Same booking system as Cala Coticcio.
For the La Maddalena beaches, you must book your spot before joining any boat tour, as the tour cannot land without a confirmed reservation for each passenger.
Parking Tips
Even in September, parking at popular beaches fills up at peak hours. The best strategy is to arrive before 9 AM or after 4 PM. Many beaches have paid parking nearby, and some require a walk of 10 to 20 minutes from the nearest available space. Park where it is legal, even if it means walking, and never block access roads. At beaches like Lu Impostu, there is a car park a short walk from the beach that serves as the main access point.
Best North Sardinia Beaches for September
La Cinta (San Teodoro): A long stretch of white sand with shallow, brilliant blue-green water and views of Tavolara Island. No reservation required. Flamingos on the lagoon side. One of the best family beaches on the island.
Lu Impostu (San Teodoro): A quieter alternative to Cala Brandinchi, with calm sheltered water and good snorkeling along the rocky edges. No reservation required, and in September the beach is even calmer. Park at the designated car park and walk down.
Cala Brandinchi (San Teodoro): One of the most photographed beaches in Sardinia, with extraordinarily clear shallow water. Visitor numbers are managed in peak season. In September it is still worth arriving early, as it fills up on sunny days.
Capriccioli (Costa Smeralda): Three sheltered coves with clear water and good snorkeling. Parking fills quickly even in September, so aim for early morning. Worth the drive from San Teodoro as a day trip.

Things to Do in Sardinia in September
Boat Tours and Island Hopping
September is the prime month for boat excursions. Full schedules are running, prices are slightly lower than peak summer, and the water remains excellent for swimming and snorkeling. Beyond La Maddalena, there are day trips available along the Costa Smeralda by sea, tours of the Tavolara Marine Reserve from San Teodoro, and various smaller group and private charters throughout the northeast coast.
Hiking and Nature
September’s cooler temperatures make hiking significantly more comfortable than July or August. The interior of Sardinia is dramatically different from the coast, with granite mountains, ancient villages, and cork oak forests. Supramonte is one of the most spectacular areas, with hiking routes to gorges and caves that would be dangerously hot in summer. The island also has several scenic coastal walks, particularly around Capo Testa near Santa Teresa Gallura in the far north.
Wine and Food Experiences
September is harvest season for Sardinian wine. The vendemmia (grape harvest) begins in earnest, and several wineries in the Gallura region, which produces the Vermentino di Gallura DOCG, welcome visitors for tastings and vineyard tours during this period. Cannonau di Sardegna, the island’s famous red, also begins its harvest cycle in September. If you are interested in wine tourism, this is the best time to visit.
Sardinian food culture is distinct and worth exploring beyond the tourist restaurants on the coast. Look for porceddu (roasted suckling pig), culurgiones (filled pasta typical of Ogliastra), seadas (honey and cheese pastry), and the various local cheeses including pecorino sardo. In September, local sagre (village food festivals) begin appearing across the island.
Snorkeling and Water Sports
The sea visibility in September is excellent, often exceeding 20 meters in the clearer areas around La Maddalena and the Costa Smeralda. Snorkeling gear is available for rent at most beach areas. More serious divers will find dive centers operating out of Palau and La Maddalena with organized dives to wrecks and marine park sites. Wind conditions in September also suit windsurfers and kitesurfers, particularly around the north coast where the Mistral wind can pick up.
Visiting Inland Sardinia
With a car and cooler temperatures, September is the right time to venture inland. Nuoro is the cultural capital of the interior and has an excellent ethnographic museum (Museo Etnografico Sardo). The Barbagia region surrounding Nuoro is where traditional Sardinian culture is most visible, and September marks the beginning of the Autunno in Barbagia festival (see Festivals section below). Orgosolo is known for its striking political murals painted across the village walls.
Festivals and Events in September
Autunno in Barbagia (Starts September)
Autunno in Barbagia is one of the most significant cultural events in Sardinia and it begins in September, running on weekends through December. Each weekend, a different village in the Barbagia region opens its doors for “Cortes Apertas” (Open Courtyards). Traditional houses and buildings invite visitors in to experience local crafts, food, music, and folk costume demonstrations that would otherwise be completely inaccessible to tourists.
The September weekends typically start with villages like Bitti and Onanì, and the atmosphere is genuinely authentic rather than performative. You can watch traditional weaving, taste local honey and cheese, hear Sardinian polyphonic singing, and eat roasted suckling pig in narrow village alleys while locals dance in traditional costume. This is the side of Sardinia that most beach visitors never see.
It requires a car and a willingness to drive about 1.5 to 2 hours from the coast into the interior. The experience is worth the detour if you have a day to spare during your trip.
SUNANDBASS (San Teodoro, Early September)
SUNANDBASS is an annual electronic music festival held in San Teodoro in early September (typically around September 6 to 16). It focuses on drum and bass and related genres, drawing a specific music crowd from across Europe. If you are traveling to San Teodoro in early September, it is worth knowing about, as it does affect accommodation availability and prices for that specific window. Book early if your dates overlap.
Maxi Yacht Rolex Cup (Porto Cervo, September)
The Maxi Yacht Rolex Cup is a prestigious sailing regatta held at Porto Cervo (Costa Smeralda) typically in the first two weeks of September. Some of the largest and most impressive sailing yachts in the world compete in the waters off Costa Smeralda during this period. Even if you are not a sailing enthusiast, watching the boats from the Porto Cervo waterfront is a spectacle. Entry to view from shore is free.
Best Areas for Couples in September
September’s calmer atmosphere suits couples particularly well. Here are the areas that work best:
San Teodoro
For couples who want a mix of great beaches, good restaurants, and easy access to boat tours, San Teodoro is the ideal base. The town has a pleasant evening atmosphere, with restaurants that fill up nicely without being overwhelming. You can walk between restaurants and the central piazza from most accommodation options in town. The beaches nearby, including La Cinta and Cala Brandinchi, are romantic in September’s quieter conditions.
Palau Area
Palau offers a more intimate, less commercial atmosphere than San Teodoro, and the proximity to La Maddalena makes early morning ferry crossings and boat tours easy. The area around Capo d’Orso has dramatic granite rock formations and quieter coves that are particularly good in September. Staying near Palau puts you close to the archipelago action without being in a party-oriented town.
Costa Smeralda for a Splurge
If budget allows, September is actually a good time to splurge on Costa Smeralda accommodation because prices drop from their August peaks while the scenery and water remain identical. Porto Cervo and the surrounding area still have an undeniable elegance in September, and the beach clubs and restaurants are open. For a romantic trip with waterfront dining and genuinely beautiful surroundings, this area delivers, especially in the first half of September.
Best Areas for Families in September
September can work well for families, though school schedules obviously constrain timing for many. If you have flexibility:
San Teodoro for Families
La Cinta beach near San Teodoro is ideal for families with young children. The water is shallow and calm for a long distance, the beach is wide and spacious, and the flamingos on the lagoon side provide a genuinely memorable sight for kids. The town has good supermarkets, pharmacies, and family-friendly restaurants. The overall pace in September is relaxed, which makes it less stressful than managing children at peak August beaches.
Capriccioli for Family Beach Days
Capriccioli on Costa Smeralda has a sheltered main bay with calm, shallow water and shade from the surrounding pine trees. This is one of the best family beach options on the northeast coast. The multiple small coves mean there is usually a sheltered spot even if the wind picks up. Bring all your own food and water, as the beach has no services.
Boat Tours for Older Children
Full-day boat tours to La Maddalena are an excellent family activity for children old enough to swim confidently and enjoy being on a boat for the day. September conditions are calmer than summer, which makes the experience more comfortable for kids who might get seasick in choppier weather. Book a family-oriented tour rather than one aimed at adult groups.
Frequently Asked Questions: Sardinia in September
Is September a good time to visit Sardinia?
Yes, September is one of the best months to visit. The sea is warm, crowds are significantly smaller than July and August, accommodation prices are lower, and the island has a more relaxed atmosphere. It is also the last reliable month for full boat tour schedules to the La Maddalena Archipelago.
Is the sea warm enough to swim in September in Sardinia?
Yes. Sea temperatures typically range from 24 to 26°C (75 to 79°F) in early September, dropping slightly to around 22 to 24°C by the end of the month. Most people find this very comfortable for swimming without a wetsuit.
Do I need to pre-book beaches in September?
For beaches with strict daily visitor caps, yes. La Pelosa near Stintino, and Cala Coticcio and Cala Brigantina in the La Maddalena Archipelago, all require advance reservations regardless of the time of year. Other beaches do not require booking but benefit from an early arrival in September to secure parking.
Do I need a car in Sardinia in September?
Yes. Renting a car is essentially required for exploring Sardinia’s beaches and interior. Public transportation between towns exists but is limited and does not reach most beach destinations. Book your rental before you travel. I recommend Smeralda Car Rental or Sicily by Car.
Are boat tours still running in September in Sardinia?
Yes, September is one of the best months for boat tours. Full schedules are still running to La Maddalena and along the coast. Tours begin to reduce frequency in October and most stop entirely by November. If you want to experience the archipelago by boat, September is the best and last reliable window of the year.
What is the best area to stay in Sardinia in September?
San Teodoro is the best all-around base for first-time visitors to northern Sardinia. It gives easy access to excellent beaches, good restaurants, and is well-positioned for day trips to Costa Smeralda and La Maddalena. Palau is a better base if boat tours to the archipelago are your main priority.
Is September busy in Sardinia?
Early September (the first two weeks) still sees good visitor numbers, as many European holidays extend into the first week of September. From mid-September onward, the island quiets down noticeably. The beaches are accessible, parking is easier, and accommodation prices drop. By late September, some smaller beach-focused establishments begin to close for the season.
Feuza’s Take: “If someone asked me to plan the perfect Sardinia trip, I would tell them September without hesitating. Fly into Olbia, book Smeralda car rental, stay in San Teodoro, and do the Le Hemingway boat tour to La Maddalena. Spend your beach days at La Cinta and Lu Impostu, and take one day to drive inland and see what Sardinia actually looks like when you get off the coast. The combination of warm water, manageable crowds, and all the boat tours still running makes September the sweet spot that most visitors miss because they book in July.”
