Sardinia’s weather today is mild and settled, as shown in the live forecast above. The island enjoys a Mediterranean climate with hot, dry summers and mild, wet winters; autumn and spring offer the most comfortable conditions for travel.
What is the typical weather pattern in Sardinia?
Sardinia’s climate is shaped by its position in the central Mediterranean. Summers (June–August) are consistently hot, with daytime highs around 30–35°C along the coast and lower humidity than many mainland Italian regions. Winters (December–February) are mild, with daytime temperatures of 10–15°C, though inland areas and higher ground can be cooler. Rainfall is concentrated between October and March, with November typically the wettest month.
How does the weather vary across the island?
Coastal areas such as Cagliari, Olbia and Alghero enjoy a moderating sea breeze, keeping summer heat bearable and winters frost-free. The mountainous interior, including the Gennargentu range, sees cooler temperatures year-round and occasional snow in winter. Northern Sardinia (around Olbia) can be slightly windier than the south, especially in spring and autumn.
What is the weather like in Sardinia in October?
October is warm and increasingly unsettled. Daytime highs average 22–25°C, with sea temperatures still pleasant for swimming. Rain becomes more frequent, especially from mid-month, but sunny spells remain common.
Is Sardinia windy in September?
September is generally calm, with light breezes along the coast. The Mistral wind can occasionally pick up in the north around Olbia, but it rarely disrupts beach plans. It is one of the most stable months for weather.
Does Sardinia get cold in December?
December is mild by UK standards, with daytime highs of 12–16°C. Nights can drop to 5–8°C inland. Rain is frequent, and snow is possible on the highest peaks, but coastal areas remain relatively mild.
