The Mediterranean yacht charter season is quite long. It starts in May and ends in early October. May and June are very pleasant as the weather is not so hot and the most coveted spots are still not crowded. July and August are the high season for most places in the Mediterranean and in some locations, like the Aegean Sea in Greece, can be very windy. The mellow weather of September makes this month ideal. Still warm and fewer crowds everywhere. October can be riskier but during the last years, it has been uncharacteristically warm with mild weather and sunshine.
