A month-by-month breakdown of weather, crowds, prices, and what to expect throughout the Greek charter season.
The Meltemi is not a problem — it's a feature. Experienced sailors love it. But for first-time charterers or families with young children, we recommend avoiding the peak Meltemi months in the Cyclades.
If your dates are flexible, ask Katerina about 'repositioning weeks' — when yachts need to move between bases, they sometimes offer significant discounts for charters that align with the repositioning route.
September is widely considered the best month — warm seas (25-27°C), golden light, fewer crowds, lower prices, and the Meltemi winds have calmed. June is also excellent with long days and pleasant temperatures. July and August are peak season with the liveliest atmosphere but also the most crowds and strongest winds.
The Meltemi is a strong northerly wind that blows across the Aegean Sea from June to September, peaking in July-August. It can reach Force 6-8 in the Cyclades, creating challenging sailing conditions. Experienced sailors enjoy it, but it can be uncomfortable for first-timers. The Ionian and Saronic are sheltered from the Meltemi.
The main charter season runs May to October. Some yachts are available in April and November at significantly reduced rates, but weather is unpredictable and many island services close. Winter charters (December-March) are very rare in Greece as most yachts are in maintenance and island infrastructure is minimal.
Sea temperatures in May range from 19-22°C — refreshing but swimmable for most people. By June, the sea reaches 22-24°C, and by August-September it's a warm 25-27°C. If warm swimming water is a priority, aim for July-September.
High season runs from early July to late August. This is when charter fees are highest, availability is most limited, and the islands are at their busiest. The most popular yachts for peak weeks (especially the last two weeks of July and first two weeks of August) can sell out 12 months in advance.
