Annual profile · Coast and sea
Marseille: the swimming season follows two curves
Average daily highs vary by 21.1 °C through the year, while the sea varies by 9.6 °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.
