Cagliari, Italy

Cagliari sits in the Mediterranean basin in Italy, and the 2015–2024 weather record gives its sunshine a clear shape: the June peak reaches a 99/100 sun score, with daytime highs around 29°C — a solid base for a sand-and-sea holiday.

Summer wins on the numbers and winter loses them; everything in between is a trade-off between warmth and crowds.
