Weather file & wind directions clarification

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?
