Perranporth Beach is a beautiful beach on the incredibly scenic Cornwall coast and is very popular with tourists, surfers....and scientists.

This is not the first time I've used a picture from this beach because it's close to where I live, but it's the first time I've ever used a picture of an actual rip current that almost resulted in a drowning.

Western Australia has some stunning beaches. Beautiful white sand, turquoise waters and of course sharks! But sharks aren't nearly as big a problem as rip currents. It all begins with an idea.
