Quick answer
July is peak summer: about 32–34°C, warm sea (about 24°C), busy islands and the highest prices. Strong north winds often blow across the Aegean, which cools islands but can delay or cancel smaller and fast ferries. Heatwaves can bring 40°C+, and some ancient sites may shorten hours on extreme-heat days.
