Is July/August too hot for Cyclades?

Temperatures reach 28-32°C with strong sun. It's manageable near the sea, but expect crowds and peak prices. Best for beach lovers.

Can you swim in Cyclades in October?

Yes! Sea temperature stays warm (22-24°C) through October. Many beaches remain pleasant into early November.

What about the Meltemi wind?

Strong north winds blow July-August, especially in northern Cyclades. Great for sailing/windsurfing, less ideal for beach lovers. Southern islands are calmer.

Are there differences in weather between the islands?

While the general climate is similar, there are microclimatic differences. Northern islands tend to be slightly cooler and windier, while southern islands are typically warmer and drier.
