I am not sure where I can find accurate wind data regarding the direction of it. For example, here on RG along with about half of the mlb weather websites it said the wind was blowing out in ATL today, while in the other half it said it was blowing in. Petco park in SD also has the wind blowing out here on RG, but blowing from L to R on many other websites and a couple saying it is going from R to L. I’ve noticed that there are discrepancies daily in these two parks, and i’m sure there are discrepancies in other parks as well that I just haven’t noticed yet.
EDIT: I am aware of all of the existing sites, just don’t know which ones are accurate since they all provide different directions for some parks. Also, I’m only interested in finding an accurate site, I am not interested in people telling me about wind not mattering lol
