Do You Know How To Read ‘Wind Socks’

It’s common to see these ‘flags’ at airports, heliports, and other similar facilities, but rarely do we think of their purpose beyond indicating whether there’s wind.

These are known as “socks” or “wind flags,” and actually have a specific system of measuring. They are divided into 5 rings, each representing a speed of 3 knots.

This allows you to accurately assess wind intensity in real-time. Next time you see one, you’ll be able to check not only if there’s a breeze, but also the exact speed it’s blowing right now.
