Climate and Average Weather in Sardinia

Surrounded by the Mediterranean Sea, the island of Sardinia is one of Italy's two autonomous island regions—the other one being Sicily. Due to its extensive coastline of approximately 1,200 miles (1931 kilometres), the vibrant island gets more extensive hours of sunshine in comparison to other holiday destinations in Europe, resulting in long, warm summers spanning up to nearly six (6) months in a year. Sardinia is home to exquisite beaches, as well as the infamous nuraghe or the historical remnants of architecture left by the Nuragic civilisation, making the island both a top tourist and historical hotspot in Italy.

Sardinia has a temperate Mediterranean climate. As such, the weather and climate in Sardinia are hot and dry during summer from July to September. Meanwhile, spring is from March to June, and autumn is from October to November, where both spring and autumn are particularly mellow and pleasant. Winter spans from December to February, and is mild and humid with occasional hot days. In terms of sunshine, Sardinia enjoys 7 hours of sunshine each day in April on average, and up to an average of 11 hours in July.

August is Sardinia’s warmest month, while January is the coldest. The average maximum temperature in August ranges around 30°C (86°F) in Alghero, while temperatures average around 32°C (89°F) in Cagliari.
