Frequently asked questions
The coast of Asturias runs from the Eo estuary, on the border with Galicia, to the Tina Mayor estuary, on the border with Cantabria. It has town beaches such as San Lorenzo, in Gijón, and many beaches and coves between cliffs.
Based on the smoothed average of our data from 2023 to 2025, the sea in Asturias is at 20°C or more from roughly 15 July to 13 September. This is an average for the whole region; each beach may differ from it.
A great deal. On the Cantabrian Sea the tide changes the size of the beach, and the swell can be strong. The water temperature alone does not tell you whether it is safe to swim: follow the flag and the lifeguard’s instructions.
