These are photos I took at the sea in Viserba the Rimini (Italy) during my holiday on July. As you can see, the water is transparent, it’s just the sand that gives a brownish-mud color to the water, especially when waves agitate it. That’s why I don’t like Adriatic sea too much.
The water had this grey-green color all the time. I miss Sardinian sea, sand and water were so clear.
