Kite surfing is going to be a lot of fun if you are in the ideal place for it. There are parts of Australia, New Zealand, Indonesia and East Timor that are believed to have the perfect setting for the water sport. In these locations, it gets quite difficult to surf with a good wind blowing. This is when kite surfing comes in.
In the ideal case, kite surfing or kite boarding is done on days when the sea is calm and quiet. Chances of a storm or rainfall should be negated. Hard blowing winds can be quite hard to handle, specially in the form of kites. Choose a day when the wind is blowing onshore. This way, even if your plans go wrong, and you find yourself in the sea, there are all chances of your being washed on shore.
Be sure to be in company of other adventure seekers who can help you in case you get into trouble while getting on the kite board, or while landing. Always use a chord to hold the kite to your boat securely unless you want it to gather some air and blow away on its own.
Practically, you are going to need the wind to pull at the kite, and it is the momentum gathered by the thrust that is going to pull your boat across the water. Choose a day when there is a slight wind rather than a calm and quite day for kite surfing. The thrill is going to remain with you for a lifetime.
