Historical 30-year sea surface temperatures across 38 coastlines in France for June. Derived from NOAA 0.25° blended satellite and in-situ marine observations.
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.
