Understanding wind directions, theory and characteristics is necessary for kitesurfing.
Understanding wind directions relative to the beach is very important for selecting an appropriate safe location for the prevailing wind. Cross-shore (side-shore) and cross-onshore winds are ideal for kitesurfing. Off shore and cross-offshore wind directions can be dangerous for kitesurfing and are best avoided.
Understanding the Wind Window is critical for managing the power of the kite and your direction of travel. The Wind Window is the three dimensional region of sky downwind of the rider in which the kite can be flown. When facing downwind, the wind window is roughly all the area the you can see.
