The wind
turns to northern and drives the humidity away, while it cools the island. In
Santorini, the sea temperature is about 23-24 degrees these days, but, of
course, the sea tends to be warmer in beaches with shallow waters (like
Monolithos) or later in the day. The temperature seems rather cool for the
Greeks, though for visitors from northern or southern countries it is rather
warm!
You can opt for beaches like Perissa, Perivolos or
Vlychada, with no waves today, unless you are an extreme sports fan! Whatever
you choose, have fun!
