Peter Rabbit is blowing in the wind

We found this Peter Rabbit weather vane near the Lingholm Estate where Beatrix Potter used to take her holidays by Derwent Water. The walled garden was apparently the inspiration for her Peter Rabbit stories. The wind was blowing south to north but notice that the arrow is pointing south. My classes find it hard to get their heads round the idea that the wind is named for the direction from which it comes not to which it goes. So the arrow points in the opposite direction to the air current. It's a bit like an electron in an electric field where the electric force points in the opposite direction to the electric field.
