I am a big fan of Balnarring when the wind is SW or SE, but I don't go there often because it is a long drive and the wind meter always seems to say there isn't much wind.

I suspect that if the wind is east of SE or west of SW it might be in a shadow?

Can anyone give me some guidance on how to read this wind meter?

For example I always assume there is 5 knots less wind at Rosebud than at South channel when it is blowing from the north.

Thanks, I was assuming that it was connected to the annamometer on the roof of the yacht club.
