I am new here so bear with me,,,I am reading the wind direction graph for north coast of NSW.Its blowing about 15 to 20 from the N / NE.
I have looked at the direction arrows, if I am reading correctly it states "Where wind is going"
Have I missed something
are you tripping.. you answered your own question. "Its blowing about 15 to 20 from the N / NE." which means it is going south
Or have i just been trolled

I think what he is (correctly?) referring to is that it says "where is the wind going" not "where is the wind coming from"
