Sardinia’s weather is a classic Mediterranean story — hot, dry summers and mild, wet winters — but the island’s mountain spine and coastal breezes make local forecasts essential. The live forecast above gives you the current conditions across the island, from Cagliari to Olbia.
What is the typical weather in Sardinia year round?
Sardinia’s climate shifts from a long, sun-drenched summer (June to September) where daytime highs regularly hit 30–35°C, to a cooler, rainier winter (December to February) where coastal lows hover around 8–12°C. Spring and autumn are the sweet spots — pleasant for hiking or beach walks, with average highs of 18–24°C. The Mistral wind can sweep across the island at any time, especially in the northwest near Alghero and Porto Torres.
What should I expect for sardinia weather in October and November?
October is still warm — think 20–24°C daytime highs — but rain becomes more frequent, especially in the north and east. By November, temperatures drop to 15–18°C and you’ll want a jacket for the evenings. These months are excellent for visiting archaeological sites like Su Nuraxi without the summer crowds, but pack a waterproof. For a 14-day outlook, the live forecast above provides the latest trends for your travel window.
What is the weather in Sardinia like for a 14-day trip in spring?
Spring (April–May) delivers mild days around 18–22°C, cool nights, and occasional showers. The island is green and wildflowers bloom. Sea breezes keep the coast comfortable, but inland areas like Nuoro can be cooler. Check the live forecast above for daily updates.
Is sardinia weather in December suitable for a holiday?
December is cool and damp, with highs of 12–15°C and frequent rain, especially in the north. Skiing is possible on the Gennargentu mountains, but coastal swimming is out. It’s a quiet, atmospheric time to explore towns like Alghero and Cagliari.
How does the weather in Alghero differ from the rest of Sardinia?
Alghero, on the northwest coast, feels the Mistral wind more than the south. This keeps summer heat slightly lower (28–30°C) but can bring choppy seas. Winters are milder and wetter than in Cagliari. The live forecast above covers Alghero conditions.
