I looked out the window, as I do every morning and, as it mostly is in the morning, the sea was flat and calm. A few minutes later I logged on to a webcam at the Rocks in Sydney to check the weather there and then to a Melbourne cam site to see how foggy it is in St Kilda. They have added another camera, the newest being at Chelsea. I had a look and two guys are surfing. How can there be waves big enough to surf on at Chelsea when the bay is so calm at St Kilda?
