Yes, June suits travelers who want warm afternoons, dry days and a sea that’s getting comfortable, along with archaeology, parks and a truffle festival in Laconi. Afternoons reach 84°F (29°C) in Cagliari and Olbia, and rain falls on only about two days.
The sights worth the trip are spread across the island, and several can only be seen on a guided tour. Su Nuraxi di Barumini, for example, admits visitors with a guide, so plan the day around the departure times.

What is the weather like in Sardinia in June?
| Month | Average high | Average low | Rain | Rainy days | Sea |
|---|---|---|---|---|---|
| May | 75°F (24°C) | 56°F (13°C) | 1.0 in (26 mm) | 4 | 64°F (18°C) |

*Long-term monthly averages.*
June is warm and mostly dry. Cagliari has afternoons of 84°F (29°C) and nights of 63°F (17°C). Olbia matches the afternoons and cools to 60°F (16°C) at night, so evenings there ask for a light layer.
Both cities average two rainy days in the month, so rain rarely interferes with a plan. Light cotton clothes work for the day, and the sights that involve long walks, like the Asinara trails or the Tharros ruins, fit best in the morning before the afternoon heat.
May is gentler, with Cagliari afternoons at 75°F (24°C) and more rain days, four in both cities. July is hotter, with afternoons at 89°F (32°C) in Cagliari and nearly dry skies. June sits between the two.
Where to go in Sardinia in June
Cagliari
Cagliari is the easy base for a first visit. The tourist office is on the ground floor of the Town Hall, via Roma 145, and the botanical garden covers five hectares. Patrizio Gennari founded it in 1866, and its shade is welcome in the warm afternoons. The Castle of San Michele also hosts exhibitions and lectures.
Su Nuraxi di Barumini
Su Nuraxi is a nuragic complex and a UNESCO World Heritage site. It’s open every day of the year, and one ticket also covers Casa Zapata and the Giovanni Lilliu Centre. Tours run in Italian, English and French.
Tharros
Tharros lies in the Sinis landscape, between the sea and the ponds. Phoenician colonists founded it at the end of the 8th century BC, and it was abandoned in 1070. The site offers guided tours and a bookshop, and a morning visit keeps you out of the afternoon heat.
Asinara National Park
Asinara sits on the northwestern tip of Sardinia and has been a national park since 1997. Admission is free. Boats reach it from Porto Nuovo at Stintino and from Porto Torres. The trails cover five thousand hectares, and in June’s dry weather they suit a full day outdoors.
Laconi
Laconi has an urban park, the Aymerich park, spread over 22 hectares. The truffle festival takes place here every year in June, which makes this month the one to choose for it. Book rooms early if you plan to stay.
Sadali and Isili
Sadali has a natural waterfall, Su Stampu de su Turrunu, that is 52 feet (16 meters) high. The Trenino Verde runs guided excursions there. Isili has the Is Paras nuraghe, 39 feet (12 meters) tall, and pedal boats for rent on Lake San Sebastiano.
What to do in Sardinia in June
Su Nuraxi di Barumini on a guided tour

Casa Zapata and the Giovanni Lilliu Centre each have guided tours of about 30 minutes, also leaving every 30 minutes. Wear comfortable clothing and non-slip shoes. Animals are not admitted, except guide dogs, and only by reservation.
Asinara by bike, horse or tourist train
Visitors can explore Asinara by mountain bike, on horseback, in an off-road vehicle or by tourist train. The Asinara donkey is the symbol of the park. Choose the tourist train or a vehicle if the afternoon heat is a concern.
The marine protected area was established in 2002.

The truffle festival takes place every year in June in Laconi. Combine it with a walk in the Aymerich park, which covers 22 hectares.
