I already had a few good sessions in Perth...maybe 5-6 on seabreezes 2-3 weeks ago. Not bad for September in my opinion!
Seabreeze is definitely good up North atm. Had a kite almost everyday last week between Gnaraloo and Shark Bay.
Season really start in Perth late October...until then you can have a few good days here and there but nothing consistent...
Better hit the midwest until then
