Hey Buzz Boy,
Perth in the winter can be a blast but you need to have a bit more sensory acuity when it comes to the weather. The winds can be very gusty and the squalls can double the wind speed in seconds.
On the bright side, we get some sick right handers allowing wicked frontside smacks.

If you have a medium to high level of ability and know your safety systems well, then enjoy winter, if not, maybe spend some more time in the gym and wait for next summer.
Good winds,
