Due to its Mediterranean climate, Cagliari has dry hot summers and mild winters. From June to September happens to be the warm season and from November to March is a cold season. Rain stays moderate through out the year. 

Tourists can travel to Cagliari anytime of the year, since the weather is not extreme. Both seasons have their own flavours to cherish. The weather hardly gets to the freezing point and usually warms up faster after the late winters.
