Weather file & wind directions clarification

Grasshopper Eddy3D

Hi
I am rather new to Eddy 3D but I can see the potential I want to learn.

Right now i am trying to implement a epw file to my simulation, everything runs fine, but I do get a message from the ABL that states:

“The average angle offset between simulated wind directions and the weather file is 95.6°.
You might want to consider changing the input wind directions to better fit the weather file.”

Is this normal, an issue or how would you recommend to fix it?

This is a warning for when you use the interpolation setting on the pedestrian wind comfort post-processing settings. Fig. 13 here talks about this tangentially.
