I'm posting this over 3 months after it was taken so I'd be lying if I said I can remember what the temperature was that day. It may have just been more stormy and misty than actually cold.
Mind you, at the time of writing in February 2017 we're in the middle of yet another heatwave (with high 30's predicted for today) so the thought of cold weather is difficult to even imagine from here.
Whatever it was, it didn't deter this school of surfers.
