The etesians (every year - “etos” in Greek) are strong, dry north winds of the Aegean Sea, which blow in the summer, especially in August.
The photo captured a cloudy and stormy summer sunset of August in the central Aegean Sea. I was a passenger on a Blue Star Ferry. I looked at the turbulent sea and was searching for the moment when the wave came in the opposite direction from the air and bounced over the sparkling water cloud.
