Its warming up but today is quite cool. Tomorrow looks like it will be cool too. However the north easters and warmer weather have started already. Not sure how that relates to wetsuits but if I go windsurfing tomorrow I'll be using my 4 by 3 full length wetsuit.

Welcome Panda.
You should be right from now on with a 3 mil. Usually by end of September and start of October its boardies and a rashy until at least end of March.
Tomorrow might be a bit cool as the water is still cold and the wind from the cool direction but at least it will be sunny.
This time last Dads day it was a nice sea breeze.
I had a super quick squirt on sunset yesterday arvo in a 3/2 s/s steamer and it was fine, I also hate the cold.

Depends how much you can "harden da f**k up". A while back I Sailed with a Swedish guy in a westerly down at La Perous. It was mid winter. I wore a 4 mill suit he was in a shorty. Obviously he really "hardened da f**k up."

Thanks all. 3mm for summer it is.

ita almost warm enuf last weekend to use boardies and a long sleeve rashie :)

never used anything more than a 2/3 steamer in sydney.
