Meteorological truth: True autumn has not yet begun. This is a liminal month—the "second summer" ( Allou genitsa in folk tradition). The only hint of change is the shortening daylight and the first, rare, dramatic thunderstorms that break the four-month summer drought.
If you want the deep, experiential answer:
This is not autumn as most foreigners imagine it. September in Greece is still summer in all but name. The meltemi winds (the strong, dry northern winds of the Aegean) begin to subside. Sea temperatures peak, often warmer than in July. Tourists thin out after the first week, but the sun remains intense, temperatures frequently reach the high 20s°C (mid-80s°F), and swimming is sublime.
