This is the Gordons Bay harbour in Helderberg, during last year's storms you can see this wave going over the harbour wall a day before the storms. They closed the harbour later on because people were in danger of being thrown from the wall.
Lots of people ran through the waves, children as well and since they've changed the other side of the wall where the boats and yachts are, the fall is a bit harder because they've laid out concrete.
There were loads of surfers enjoying the massive waves as well.
