The Meltemi Winds

The single most critical variable for any traveler to the Cyclades is the Meltemi. This dry, northerly wind is not merely a weather event; it is the regulator of the Aegean climate.

Originated from high-pressure systems in the Balkans colliding with lower pressures in the Eastern Mediterranean.

The Seasonal Triptych

April – May – Early June

The Vernal Awakening

Spring in the Cyclades is a revelation. Following the winter rains, islands are verdant and carpeted in wildflowers. Prime for hikers and cultural travelers.

Mild temperatures (20-25°C)
Orthodox Easter celebrations
Fewer crowds and lower prices
Green landscapes unique to this season

Late June – July – August

The High Energy Apex

The period of maximum intensity. The sun is relentless, the Meltemi is at its peak, and the islands are operating at full capacity.

Peak beach club and nightlife scene
Maximum ferry frequency
Vibrant social dynamics
Strongest Meltemi cooling winds

September – October

The Golden Autumn

Often cited as the optimal balance. The Aegean acts as a heat sink, retaining warmth well into October, yet air temperatures are comfortable.

Warmest sea temperatures (23-24°C)
Soft light, ideal for photography
Dissipating crowds and relaxed vibe
Wine and agriculture harvest seasons
