The Mazaro (spelt also as Màzaro) is a river in Sicily, Italy.

The Mazaro river flows 28 kilometres (17 mi) across south-western Sicily,[1] from its source in Rapicaldo, located within the Salemi city boundaries, to the Mediterranean Sea in Mazara del Vallo.

"Mad sea" phenomenon[edit]

The river is characterized by a periodical phenomenon locally known as marrobbio (also known in English as "mad sea"), which consist in rapid and dramatic sea level oscillations seemingly caused by sudden atmospheric pressure changes;[2] similar phenomenons were observed only in a very few other places in the world, including Nagasaki Bay in Japan (where the phenomenon is known as abiki) and Ciutadella (in Menorca, Spain, where it is called rissaga).[2]
