Below is a picture of foam and granite along the coastal rocks just west of Petrel Cove on the southern Fleurieu Peninsula.
It was made on a day after the big storm in early May. Though the storm had passed the seas were still surging and they were too rough for the surfers. The 2 metre high waves dumped, rather than rolled into the shore.
The picture above refers back to this earlier picture of foam as well as to this one. This is what the littoral zone looks like during, or just after, a big storm from the south west. The foam quickly vanishes.
A huge wave swept over the rock I was standing to take the photo just after I'd made the photo. I just managed to avoid being caught by the wave.I heard the wave coming whilst I was photographing. It was a rogue wave. So I quickly moved to the foot of the cliffs. On other occasions that morning I was not so lucky. I wasn't quick enough. I was too absorbed in photographing the foam. Wet shoes, socks and pants was the result. I managed to keep the digital camera dry though.
