What are Meltemi winds and how can they affect your yacht charter vacation?
The Meltemi wind (/melˈtemē/ /mɛlˈtɛmi/ ) is the strong dry north wind that blows in July and August across the Aegean Sea. ‘The Meltemi winds are known by old Greeks as the Etesian northern winds and are not viewed in a bad way as they bring cooler weather, low humidity, and good visibility.’ Here we will cover what you should consider when they’re present and how Meltemi winds may affect your yacht charter vacations.
The Meltemi Weather Conditions
The Meltemi winds of Greece are seasonal, a hot and dry wind that blows from the north of Greece across the Aegean Sea. They are a natural phenomenon that occurs yearly, which is why you may sometimes hear them referred to as Etesian Winds. The wind is created by atmospheric pressure differences between Europe and Africa combined with different temperatures across the Mediterranean Sea. The wind starts blowing from the north across the seas, and because there is little to stop it, the wind builds up quite some speed before it reaches islands or what may be in its way.
The Winds in July and August
In the months of July and August, the Meltemi blows strongly, but you can expect these northern winds to blow anytime between June and September. These winds peak can reach 7 and 8 Beaufort. What does that mean? Waves 13-19 ft, white foam streaks off breakers. That can put winds as high as 75 miles an hour. These winds can provide some relief in the heat of the season, as it helps to reduce the very high summer temperatures experienced in parts of Greece, but it does make getting around a bit tricky.

The islands of the Aegean. The most well-known for being affected by the winds are The Cyclades islands. Mykonos may be nicknamed the island of the winds, but nearby Andros and Tinos probably experience the Meltemi the most. The effects of the Meltemi do not only run through the Cyclades. The eastern side of mainland Greece, the Sporades, islands of the Northeastern Aegean, the Dodecanese Islands, and even Crete are exposed to them.
