In Short

The wind won't start cooking until September, August can have some days but its hit and miss. Swell is at its best from May/June through until October, If you only kite waves then you needn't bother bringing kites in the winter, nearly all the wind comes from an Easterly direction which can be good if you like flat but down the line it is not. You need summer SW winds to get good wave riding
The wind and waves align nicely between late August to early November...
If you are a Southern wave snob (no offence) then you might have reason to complain, If you like good small waves in awesome scenery with the occasional big swell then you'll be more than happy...
Just remember it isn't Margs, heaps of crew flood up every year and complain its not as consistent, or isn't big enough for their ego

the great thing is, line ups remain uncrowded whilst these crew talk about how good the surf is down South from the car park
