The whole adelaide coastline is pretty good with some flat water spots. In summer we get good 18-23knot seabreezes for weeks on end. But you can kite pretty much anywhere in adelaide besides some areas down south but im not going to give away the good spots

there all mine
Then theres some waves up the mid coast and you can ite there if you can be bothered driving. I've heard the murry mouth is good besides its sharkiness. Theres also Boggy Lake if you can be bothered driving for ages, its sorta like Lake Hatteras except probably a bit crapper. Theres sposed to be good spots down at yorkes but i wouldnt step foot in water there, physco.
