Annual profile · Coast and sea

Sardinia: the swimming season follows two curves

Average daily highs vary by 14.2 °C through the year, while the sea varies by 11.8 °C. Air and water temperature should therefore be considered separately.

The practical difference

The month with the highest daytime temperature and the month with the warmest sea need not define the same travel window. Rain and sunshine help resolve the trade-off.
