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.
On the early 1900s farm, the practical determination of wind conditions and what they could mean, were from first-hand observation, experience and local knowledge. A wind vane (also called a weather vane) was a pointer that freely rotated on the top of a fixed vertical rod. It was designed to swing easily and point to the direction from which the wind was blowing.
