Why Is the Sea So Blue When Sailing in Greece?

On occasion, the reality of a holiday can be quite different from the picture-perfect images plastered across brochures and websites, which can leave holiday-goers feeling understandably hard done by. But when it comes to the promise of crystal-clear waters in the Mediterranean Sea, the reality is just as good as you could imagine. But why? Why is the Mediterranean so perfectly blue in colour? And why does it put other bodies of water to shame?

The answer is relatively simple and lies in the scientific make-up of the water itself. Imagine a brand spanking new white shirt – never worn and never washed. If it stays unused, it will stay perfectly white in colour. Well, the Mediterranean Sea is a little similar. It is lacking in a number of nutrients that lead to plant growth in other seas and oceans (causing that more familiar green-brown colour that is so unattractive), and as such it retains its wonderful blue hue.

But if all that is too close to a science lesson for you, just go for this light-reflecting explanation instead: the Mediterranean Sea is so perfect and blue because when you are sailing in Greece and the surrounding waters, the sun always shines.
