August in San Sebastián is 20.5 °C by day and 22.7 °C in the sea. This is the year's peak for both water and load: 5 out of 5.
August is all this sea can manage: 22.7 °C, and it gets no warmer. For comparison, the Costa del Sol reads 22.6 °C in August and 15.4 °C in its coldest month — close to what this shore offers at the height of summer. The city is full: housing is dear, viewing flats is pointless, and La Concha has no spare sand. Come for the bay, and make the decision in September or February.
