My backyard is surrounded by a six foot privacy fence. The back of the yard has a six foot hill and one of the sides is all cypress trees. So much of the wind into my backyard is blocked but I still find the anemometer to be useful as a relative measure. I completely ignore the wind direction but if I see that there's been a 15 mph wind in my backyard, I know the wind in the neighborhood is a good bit higher.
