Well I just spent the last few hours getting my arse handed to me.
When I got there I saw quite a few near perfect tubes rolling through south of Trigg. Absolutely spectacular and very much unexpected and very few people (like Zuke said) out there. It got consistently worse though, but by Perth standards was still cranking when I called it quits after one too many cold water cramps and over the falls excursions.
I am really surprised by the quality of some of the waves lately, coupled with incredible winter weather. For once, it's good to be a surfer in Perth
