September in San Sebastián is 19.5 °C by day and 21.5 °C in the sea. Load has fallen from August's 5 to 4 out of 5.

Late September brings the film festival, held here since 1953, and for a week the centre is tight. The rest of the month is a working one: schools have started, the university is open, the beaches have emptied. There are 3 international schools, a hospital 10 minutes away, and living without a car scores 5 out of 5. For a family choosing a city, September is the honest month.
