My AWS is at head height. What height should the anemometer really be,

It's really complicated, Hugh!
10 metres EFFECTIVE height, so any nearby trees and buildings need to
be taken into account within 10x their height from the anemometer.
Some anemometers look really high - say 20 metres, but their effective
height is only 10 metres.
Have a look at the Observers' Handbook if you can, it's all in there.
Only mean speed should be adjusted, gusts remain as read.
Best wishes,
Ken


Thanks all.

Mine is about 5 metres on my garage roof. As mine is for my own use I
"calibrated" it against a number of readings over a period of time from
nearby official observations. It gives sensible readings most of the
time except when the house blocks it!
