Craziest Wind I've Ever Seen

I was at Pleasure Bay, wind was too light to kite, so I went for a unicycle ride around the bay. About halfway around I felt a wind shift. Suddenly a cool NE wind was blowing straight in my face. I looked forward, at the flag on Castle Island, NE wind. I looked back at the flag at the kite launch, S Wind. The flags were pointing towards each other! @*!?? Wasn't this breaking the laws of physics? Sailboats in the harbor were going in all different directions at once. I expected to see an alien spaceship descend from the sky. Picture- The graph is not very impressive.  I was wondering if it could show 2 wind directions at the same time.
