January is the perfect time to kite in Cape Town, South Africa.
Right in the middle of summer, you'll have sunny weather, awesome wind and one of the most beautiful cities in the world. You might even catch the Red Bull King of the Air comp while you're there http://capetown-watersports.com/red-bull-king-air-2014/
Plus the currency is weak, so you can insane deals on gear, and your accomodation and living expenses will be really affordable. For all the info you might need on Cape Town, check out this site specifically for Kitesurfers. http://capetown-watersports.com/
