The Cantabrian Sea is usually cooler than the Mediterranean, in San Sebastián too. Before you swim, check the latest reading for your beach and whether it is a measurement or an estimate.
Yes. In San Sebastián the tide changes the size of the beach and the state of the sea a great deal. The water temperature alone does not tell you whether conditions are good for swimming: follow the flag and the lifeguard’s instructions.
