Typical climate
Warm in September
September is the other “best month” for many people: sea still warm, days shorter, heat less brutal.
The south stays warm, often mid-20s, with fewer extreme days than August. The north cools fast.
Places that usually fit
Mediterranean
Spain, Italy, Greece and Croatia commonly stay in the mid-20s.
Algarve and Andalusia
Often the steadiest sun of early autumn.
Central Europe
Pleasant early in the month, unmistakably autumn by the end.
