When to go
From the 2026 climate study, not the live forecast.Structural odds, not a verdict — the live forecast can still surprise either way.
Jerzu, Sardinia hit 48.0°C on 24 July 2023 in the Cerberus heatwave — peak summer is now a real heat-risk window. The Sardinian coast itself is breezier and 3–4°C cooler than inland, but the inland fires are real. May–June and September–October keep the postcard image; August does not.

Common questions about Cagliari
When is the best time to visit Cagliari?
May–June and September–October are when we'd go. Skip July–August: heat that regularly passes 35°C. The live forecast on this page shows what the next two weeks look like.
Is Cagliari worth visiting in September?
Yes. September sits inside the best stretch (May–June and September–October). Once your dates fall within the next two weeks, the forecast above gives you the real picture.
Is Cagliari good in July?
We'd go another month: July means heat that regularly passes 35°C. Locked dates? It still works if you make sure the room has air conditioning that works.
Dates settling? Compare hotels on Booking and flights on Kiwi — both open with the forecast's best window pre-filled.
