You need to find out the exact angle of the wind, then you can use a calculation to find the exact tail- and sidewind.

**At first you determine the base angle of the wind by judging the wind-image shown in-game.**

The wind goes clockwise in 22.5° steps: 0°, 22.5°, 45°, 67.5°....

Lets say you have 3 wind going straight from left to right, which is obviously 90°

**Now you drag the cursor from 50% to the point where the in-game-shown wind turns.**

**If the in-game-shown wind turns at about 50%, you need to add 22.5°**

If the in-game-shown wind turns at about 0%, the wind is actually correct (add 0°)

So in this example lets say the wind turns at about 25%.

That would be 11.25°

Add this to the base angle we determined earlier and we get the correct wind angle of 101.25°

Now to calculate the exact parts of the wind, you may use this calculation:

tailwind = cosine(angle * PI / 180) * wind;

sidewind = sine(angle * PI / 180) * wind;

______________________________________________

tailwind = cosine(101.25 * PI / 180) * 3;

sidewind = sine(101.25 * PI / 180) * 3;

______________________________________________

tailwind = -0.59m/s

sidewind = 2.94m/s

Ok, now I'm confused

1 - is the wind direction bug also on the Driving Range?

2 - if this is true and i set the wind to East as in your example, is the wind angle 90%? (wind arrow changes if i press cursor right 1 time) or is the wind angle 90% + 22.5% ( arrow changes between 22 and 23 presses on the left cursor).

I was always of the assumption that the wind bug was as follows with your example of wind to the East:

wind % = 90% (East) + the number of clicks to the left where the wind arrow changes + 11.25

This was taken from a website many years ago where it was explained including pictures

**Quote:**

Each arrow direction signifies 22.5 degrees inside the azimuth. By moving the camera just enough so the arrow moves one way, then back the opposite direction until it changes again you can gain a feel for where inside the 22.5 degrees it is truly pointing. However, you still need to add 11 degrees to what you see, because of the bug with the wind.

It is possible that the wind ARROW showing a wind direction coming from the South (180 degrees)- pointing North (0 degrees), could actually be as far off as halfway to the NE, or about 32 degrees
