Water temperature in Santorini: sea and beaches at the moment
Now the average temperature of the sea on the beaches of Santorini is +22°C...+23°C — it's time to go swimming!
Living on the island and observing the water temperature in Santorini revealed a little secret: the water on the black beach right by the shore is noticeably warmer than on the red and white beaches, for example 🙂 The conclusion is pretty obvious: black sand always heats up faster.
We have collected more information about sea temperatures on a separate page.
