Sardinia has a Mediterranean climate, with the exception of some interior areas, whose weather is harsher.
In the coastal areas, where most of the population lives, winters are mild, thanks to the presence of the sea. Snowfalls are rare (one every 5-10 years), and temperatures very rarely fall below zero; summers are hot and dry. The low humidity rate and the prevalence of sea breezes make it relatively easy to enjoy the high summer temperatures, which often reach 35-40 °C.
The climate is harsher in the interior areas. During winter, the Gennargentu Mountains are often mantled with snow and temperatures frequently drop below zero. In the summer, the climate is cool, especially during the night hours. It is rarely hot for many consecutive days.
Rainfall is scarce along the coasts and in the southern area, with mean values of less than 500 mm per year; in particular, the Capo Carbonara area has the absolute minimum value, both on a regional and a national level, with an average of only 266 mm per year. In most of the interior areas, mean average rainfall is 500-800 mm per year, while the region’s highest values occur near the main mountain ranges.
Sardinia is a windswept region, the dominant wind being the Mistral (coming from north west), but the Sirocco is also fairly frequent. The former mitigates summer heat, though at times its speed damages agriculture and it is a contributing factor to brush fires. The prevalence of winds has encouraged the installation of a number of wind farms on high points and industrial parks.
