The Meltemi winds are seasonal, strong, dry winds that appear all over the Aegean.
The Meltemi helps bring down summer temperatures and clears the air, providing increased visibility. They are strongest during July and August, but you may also come across them in June or September. The Meltemi generally blows during the daytime, typically being at its strongest during the afternoon and early evening. That said, it’s not uncommon to have full-blown Meltemi wind, even in the early morning or during the night.
It is always a consideration in the summer months, in the Cyclades. If the winds are really bad, no one is going anywhere off their anchorage. Even the biggest boats cannot fight the Meltemi winds.
