Sardinia Weather from September to December

Sardinia Weather in Autumn: The last 21th of September the Autumn officially begun, it’s a very interesting period of time in Sardinia, thanks to its mild Mediterranean climate. Especially in September and October days are still long, temperatures high and the sea water warm enouth to keep swimming. Especially if you come for nothern European countries the difference is huge, just think that in the last years it’s quite easy to arrive up to Christmas with only a handful days of rain and high temperatures (around or even over 20°C, like it was still Spring).

The Sardinian warm Autumn:

September in Sardinia is definetely a Summer month, thanks to lots of sunny days and pleasant temperatures, with an average high of 26 degrees, but with less tourists on the beaches, restaurants, clubs and roads. While October welcomes cooler temperatures and shorter days across much of Europe, Sardinia is still a hub of warmth and sunshine, experiencing average highs well into the low-20s. Basically the weather begins to cool off in November, with average monthly highs hanging around the mid to high-teens. December is just a couple degrees cooler actually (average high around 15 degrees). The cooler temperatures do offer some great outdoor adventure conditions, ideal for cycling and walking, explore ancient ruins, coastal art cities and inland authentic villages. This is also the best time of the year for picking mushrooms in Sardinia.

The Rainy Season in Sardinia:

sardinia-everage-rainfallAutumn is also the beginning of the Sardinia rainy season, but no worries, rains – even if enough for actual needs – are definetely not abundant. They typically fluctuate from 400 to 550 millimetres (15.7 to 21.7 inches) per year on the coast (but locally they can go even below, such as in the southeastern tip of the island). Altough in the inland rainfall may exceed locally 700 millimetres (27.5 inches) per year in hilly areas, and 1,000 mm (40 inches) in the mountains. This is also the reason why between the second half of Setpember and the first half of October, lots of religious festivals take place all over the island, invoking the arrival of the rains.

Weather in Sardinia not uniform all over the island:

Being Sardinia so large and hilly, weather is not uniform. The climate of the island in fact  is variable from area to area, due to several factors including the extension in latitude and the elevation, that’s why it can be classified in two different macrobioclimates – “Mediterranean pluviseasonal oceanic” and “Temperate oceanic” – and several others variants and classes for a combination of 43 different isobioclimates. In particular the East is drier while the western coast has a higher distribution of rainfalls even for modest elevations (for instance Iglesias, elevation 200 m (656 ft), average annual precipitation 815 mm (32.1 inches)). The driest part of the island is the coast of Cagliari gulf, with less than 450 mm (17.7 inches) per year. In fact  Cagliari is the Italian city with the higher number of sunny hours per year.
