Home > Shopping Tools > Weather Station Glossary of Terms > wind vane (definition) A wind vane is a device that measures the direction of the wind. The wind vane is usually combined with the anemometer. Wind direction is the direction from which the wind is blowing.
It's a very simple mechanism. Of course, it only works properly if the wind flows freely and isn't blocked by buildings, trees or plants. This is the very reason why weather vanes are always placed atop high buildings and church steeples. One of the oldest wind vane ornament designs is the chicken or rooster shape.
