How dangerous are rip currents?  When waves break on a beach, they push water towards the shoreline. Once that water reaches the shore, it has to find a way to get back out to sea, and it does this by flowing downwards into deeper channels in the surf zone. Once the water is in these deeper areas, it can flow back out to sea away from the shoreline. These deeper channels are called rip currents. They are a major cause of death and it's well following our surf scientist Dr Rob Brander to find out more how to spot a rip. Check out this video too:
