You can find a wind direction using 8 point compass rose (wind rose) diagram. It’s a graphical tool used to display the orientation of the cardinal directions and azimuth degrees.
N – North (0°/360°)
NE – North-East (45°)
E – East (90°)
SE – South-East (135°)
S – South (180°)
SW – South-West (225°)
W – West (270°)
NW – North-West (315°)
To define direction of wind blow at particular location, just turn your face straight towards wind and compare with the diagram.
Wind in Kitesurfing
The Wind Window
The Wind Window is the area in front of you where you can fly the kite in. It’s dynamic wind window so when you are on the water in motion, wind window is moving with you.
The wind window rotation degrades the performance when riding fast in a path upwind. To minimize the wind window rotation and sail upwind as much as possible, the kiter should keep the slowest board speed without sinking the board by lack of hydrodynamic lift. High flotation boards like surfboards are preferable in such cases. Also, keeping the kite high in window, pulling up the user and the board, is quite efficient in coping both with the reduced hydrodynamic lift of the board and with the intended reduction of the board speed.
Cross-shore and cross-onshore winds are the best for unassisted kiteboarding. Direct onshore winds carry the risk of being thrown onto land or stuck in shallows. With direct offshore winds kiter can be blown away from the shore in the event of equipment failure or loss of control. Beginners should avoid riding with more than 15 knots.
Most twintip boards and inflatable kites would be barely rideable below 11 knots, therefore for most cases kiter should focus on the winds classified as moderate up to strong.
