Why is swimming not allowed on the beaches of Palermo?"?

Question

There are notices up from the port authority, which are generally followed apart from a few reckless kids and hardy old folk.

Answer 1

My guess is that there is a sewage problem there.  There is an area near Napoli where the sewage is dumped.

Answer 2

well, it could be a fishing area.

Answer 3

Probably a sewage problem.... the signs go up when raw sewage is let go in a beach area there.

Answer 4

I am presuming its because Palermo is mainly port/urban area. Maybe able to answer your question properly soon as will be visiting next week.
