Summer in the Cyclades begins in May and ends in early October.

Under normal conditions, the temperature in May and September reaches 19 to 20 degrees Celsius, while in June, July and August the minimum is 25 degrees and can reach 32 to 35 degrees.

The meltemia [etesian winds], which intensify in July and August, bring relief from the sweltering heat, and thus one only rarely experiences a heat wave. However, the north winds often blow with great force, consequently making the sea dangerous—particularly for amateur yachtspersons. The winds intensify in the morning and afternoon hours, and die down in the evening.

Do not be fooled, however, even though it may be windy; the sun still reigns supreme in the Cyclades, giving life to us and to everything around us—but this is beneficial only when we exercise prudence whenever we are exposed to it and also use sunscreen protection.

At sunset, humidity makes its appearance and it gets chilly, especially near the water. For this reason, it is recommended that visitors pack a light jacket, light sweater or sweatshirt in their suitcase for their evening outings next to the waves.
