Anyway, the haze that you see there is from the cold ocean air moving in over the land. The water temperature at the time was only 12°C - which I'm guessing is why that wetsuitless mad surfer person decided to come in to shore.
In case you're wondering, I know it was 12°C because my friend and I (he with his thermometer-watch) hit the waves for all of 4 minutes. It was very unpleasant. Cold-sandy water, with plenty of seaweed constantly wrapping around our legs.
Everybody says Clifton's a great place to enjoy the view, play in the sand, and relax on the beach - but for swimming, she was certainly not made. Now, this is mostly the case, but I have to say that if you catch the tides just right, Clifton's water can actually be reasonably warm... even approaching a swimmable 19°C! ;)
