Wind window kitesurfing


A kite wind window is the area where the kite can fly. This is a three-dimensional semi-dome. In the wind window there are three components: the power zone, the intermediate zone and the edge of the wind window.

Power zone

When you can feel the wind in your back, you will find the power zone lying in front of you. In the picture above you see the red and orange colored areas where this is indicated. This is the part where the kite catches wind the most and thus where the kite generates the most power. A Power zone is a risk zone where you should go with caution, but this does not mean it’s dangerous. It’s a learning process on how to use it. When water-starting or when the wind isn’t blowing as hard you will have to send the kite faster and closer through the power zone. When the wind is blowing harder then you should avoid it correctly.

The intermediate zone

As the name suggests, this is the area with less force. This is located at the top and sides of the wind window. This you can see in the picture as the colour green. You will use this zone more when the wind is blowing a lot harder.

Window border (edge of the window)

This is the furthest a kite can fly into the wind. A kite has the least power at the window edge. In order to know where the kite is along the wind window, we have classified this as a clock. When the kite is just above your head, this is called 12 o’clock or the zenith. On the right, all the way towards the ground it’s called 3 o’clock and towards the left 9 o’clock. You can either launch or land the kite at the edge of the window (9 or 3 o’clock). The kite is then slowly brought up to 12 o’clock or brought down from 12 o’clock (as safe as possible). Imagine a semi circle (dome) in front of you like the image below and you’ll see that the edge of the window starts at 9 0’clock and ends at 3 o’clock.
