June in San Sebastián is 17.5 °C by day and 19.9 °C in the sea. Load is 4 out of 5: the season is only starting.
June shows what kind of sea this is. 19.9 °C is the Bay of Biscay, not the Mediterranean: the same month on the Costa del Sol reads 19.1 °C. People mostly go in wearing a wetsuit, which is why Zurriola has surfers all year. The swimming season is short and the summer air is mild: 17.5 °C by day against 24 °C in Marbella. Air conditioning is rare here, and unnecessary.
