Best Time
The best times to visit Izmir, for exploring the city, the monuments and the neighbouring towns such as Ephesus and Pergamum, are spring and autumn, ie the months of April and May, and from mid-September to mid-October. In fact, summer is often very hot, especially in July and August.
For a beach holiday, you can go from June to September.
September is probably the best compromise between seaside and cultural tourism, if you wish to do both.
