Cape Town South Africa is a good spot.
There are a few spots for exactly what you are looking for.
You've got Muizenberg, with warm water and small to medium waves that break quite close to the shore, and long stretches of beach perfect for nailing any tricks you're working on.
You've got Big Bay, with perfect wind and the most prime kickers you'll ever find. So good the Red Bull King of the Air is coming back there in January 2014! http://capetown-watersports.com/red-bull-king-air-2014/
And who could forget the renowned Kite Beach, with mad wind and just the craziest waves you'll ever ride.
Pair all of those with SA's weak currency and friendly locals and you have the perfect place for a kiting holiday!
