Water temperature and wave height on the beaches of Santorini

📍 Santorini – Coastal Overview:

Santorini, a volcanic island in the Aegean Sea, offers a dramatic coastline with beaches made of black, red, and white volcanic sands. While it doesn’t have the long stretches of classic sandy beaches, its unique geology creates a stunning and unforgettable seaside experience.

Beaches are mostly located along the eastern and southern coasts. The western side features towering caldera cliffs — beautiful, but not swimmable.
