Understanding Wind Socks: Definition, Types, and Reading Guide (PDF)

A wind sock, sometimes called a wind cone, is a conical tube designed to indicate wind direction and relative wind speed. Wind socks are used in meteorology, aviation, and chemical plants for safety reasons. Made from light, resilient materials such as nylon or PVC, wind socks are often brightly colored or have reflective surfaces to enhance visibility. They are usually white, orange, or red for maximum contrast against most backgrounds.
