The "average" direction is done by calculating the resulting vector. So if
the average is tending to north, something in the calculation is not right.
Zero wind has no direction. Even if the hardware is showing a direction
with zero wind (for instance: the direction the vane is pointing) there
cannot be an effect on the "average" direction, because the current vector
has a zero length and cannot influence the result of the "average"
direction in any way.
Since I never have seen tending the "average" direction in any direction in
calm winds: is this really a weewx issue? Or something else (hardware,
driver, skin, ...)?
