Côte d’Azur & Corsica vs English Channel & Brittany

France’s Mediterranean coast (French Riviera and Corsica) enjoys sheltered 24.5–25.5°C August waters protected by the Maritime Alps. Conversely, Brittany and Normandy face 8–12 meter tidal ranges and strong currents that continuously mix the water column, limiting summer temperatures to 16.5–18.0°C.

Oceanographic Phenomenon:Ligurian Current vs Macrotidal Channel Currents
Thermal Lag Characteristic:Corsican and Riviera thermal lag: sheltered gulfs retain comfortable swimming conditions (21.5°C) well into October.
Peak Bathing Average:August (24.8°C)
