Sardinia Climate Patterns

Sardinia is warm, dry and windy, with a sharper difference between coast and interior than its size suggests.

The pattern

Summers are hot and reliably dry. Coastal highs sit around 30-32 °C in July and August, tempered by sea breeze; the Campidano plain and the inland valleys regularly reach 35-38 °C. Winters are mild on the coast, generally 10-16 °C by day, and this is when nearly all the rain falls — annual totals are low, around 500-600 mm on the coast.

The mountains

The interior is a different climate. The Gennargentu holds snow from December to March and has a small ski area at Bruncu Spina; Barbagia villages at 700-900 m are cold and wet in winter. Visitors who plan a February trip around beaches and end up inland are routinely caught out.

The mistral

The north-westerly mistral blows for a large share of the year, strongest in winter and spring. It keeps summer heat bearable on the west and north coasts, makes the island excellent for sailing and windsurfing, and can disrupt ferries and small-boat excursions at short notice — including the boat-only beaches of the Gulf of Orosei.

Practical notes

• The sea is warm enough to swim from roughly June to October, warmest in late August and September.
• Wildfire risk is high from June to October; the combination of drought and wind is what makes fires spread.
• Boat trips are weather-dependent — build slack into any plan that ends with a flight.
• Pack for the interior separately from the coast if you are doing both.
