What is the meltemi wind and how does it affect a visit?
The meltemi is the strong, dry north wind that blows across the Aegean in summer, strongest in July and August. On Milos it mainly affects the exposed north-coast beaches like Sarakiniko and can occasionally cause boat tours to Kleftiko to be cancelled for safety.
It is not constant, but on windy days you head to the sheltered south-coast beaches instead. The meltemi eases after August, which is one reason September is such a good month. Checking the wind forecast helps you plan beaches and boat trips around it. Anyone visiting Milos in summer can understand the meltemi, the strong. Dry seasonal wind that sweeps down across the Aegean from the north during the warmer months and is at its most powerful in July and August. It is a defining feature of a Cycladic summer, bringing clear skies and cooler air but also gusty, sometimes fierce conditions on exposed coasts.
On Milos the meltemi matters chiefly for two things: the beaches and the boat tours. The exposed beaches on the north coast, above all the iconic Sarakiniko, can become very windy and uncomfortable when the meltemi blows, with choppy water. The popular boat tours to the southwestern caves of Kleftiko are occasionally cancelled at short notice for safety when the sea gets too rough. The key point is that the wind is not constant and the island is shaped so that you can usually escape it: on windy days you simply head to the sheltered beaches on the south coast, which stay calm. You build flexibility into your boat-tour plans.
The meltemi also eases noticeably after August, which is a major reason the calmer, still-warm month of September is so highly rated. By keeping an eye on the wind forecast and staying flexible about which beach to visit and when to take a boat trip. You can plan around the meltemi easily and barely have it affect your holiday.
