Cyclades and Saronics Sailing Conditions

The Saronic Gulf, Argolic Gulf and eastern coast of the Peloponnese is a protected cruising area with consistent winds, averaging Force 4-5 in the summer. Some of the area is affected by the Meltemi wind and in the evenings there can be katabatic winds off the high mountains of the Peloponnese although these are usually isolated and only last for a few hours before dying down.

Stronger Meltemi winds from the north in the height of summer, more open seas and greater distances between islands means that to sail in the Cyclades requires a skipper with experience. Whilst winds average Beaufort 4-5 they can rise to a 7-9 in high summer, especially July and August.
