Sardinia has a typical Mediterranean climate with long summers. It is hot and dry from May to October, making the crystal clear waters all the more inviting. Coastal temperatures reach an average high of 29°C in July and August. Inland, temperatures can even rise to 40°C.
September and October still see a lot of sunshine and winter months are mild and damp, although the mountain regions can see temperatures fall to 0°C. Spring begins in March and gets a good amount of sunshine; it is an ideal time to visit as it is hot during the day and cooler at night.
Sardinia is also known as isola del vento or ‘the windy island’ due to the winds that come across the Mediterranean. Winds such as Scirocco, a hot wind originating from the African deserts in the South, the Mistral, a strong north-westerly wind, and the Levante, a moist wind from Northern Africa, mean that the island is a top destination for surfers and sailors.
