Sailing in Greece: the meltemi and why the Saronic Gulf is so popular

Greece has more islands than a week could ever show. Yet the most important question for your planning is not which island but which wind. In high summer a single wind decides almost everything in the Aegean: the meltemi.

The meltemi blows from roughly June to September from the north to north-east across the Aegean, most often and most strongly in July and August. It typically freshens during the day, peaks in the afternoon and eases in the evening – but on some days it blows through the night, and it can last several days in a row. In the open waters of the Cyclades it often reaches strengths at which smaller boats are better off in harbour.

What this means for you:

• In the Cyclades, sailing in July and August is often sporty and calls for experience or a skipper. Legs north against the wind are hard work.
• In early summer and autumn (May, June, September, October) the meltemi is rarer and weaker; lighter winds make the open sea pleasant.
• If you want to sail more calmly in high summer, choose a more sheltered area.

The Saronic Gulf lies right in front of Athens. The islands of Aegina, Agistri, Poros and Hydra and, a little further on, Spetses and Ermioni on the Peloponnese are close together and quickly reached from the mainland. The meltemi usually blows less strongly here than out in the Aegean. Add to that a short journey: the marinas at Alimos are a short drive from Athens airport.

Our week-long route idea from Alimos goes via Aegina, Poros and Hydra to Spetses and Ermioni; for four days there is a shorter loop via Aegina, Poros and Agistri. Both describe the legs in nautical miles.

Both suit the Saronic Gulf. The catamaran lies more calmly in wind and offers room for groups; the sailboat is the classic choice for guests who want to sail. In the Cyclades in high summer many guests feel more comfortable on a catamaran because it barely heels.

For boats without a skipper, providers in Greece usually ask for a recognised boat licence and often a second experienced person on board. Which documents apply to your boat is shown on the boat or explained by the provider before booking. In meltemi conditions a skipper is worth considering even for experienced sailors.

May, June and September combine warm weather with lighter winds; October is often still pleasant. July and August are the hottest and windiest months – then the Saronic Gulf is the most relaxed choice.
