The weather station is located on the roof of my house, but the site is quite sheltered from the wind. As such the wind is not a good indicator (except for me) of the wind in Christchurch. It can be blowing quite hard in other areas around Christchurch but here it can be quite gentle. As such you may notice that the wind is reported as normally from the North and only a few km/h in speed.
