Wind direction, and someone experienced can take a guess at wind speed.
A wind sock is used to show the direction of the wind.
Wind socks measure the direction of the wind when the wind blows into the open end and the sock points the way the wind is blowing. Wind socks can also measure the strength of the wind. If a wind sock is flapping about gently the wind is only light. If a wind sock sticks out in a straight line the wind is much stronger.
A wind vane or a wind sock.
The wind direction is measured with wind vanes or wind socks. Sexagesimal degrees.
Wind direction, and someone experienced can take a guess at wind speed.
The appearance of the wind sock gives a broad approximation to the wind speed, and a pretty good indication of the wind direction.

Wind socks measure the direction of the wind when the wind blows into the open end and the sock points the way the wind is blowing. Wind socks can also measure the strength of the wind.

An air sock is another name for a windsock, a conical open-ended tube designed to indicate wind direction and relative wind speed.
A wind sock is a tool that shows what direction the wind is blowing in. While relative wind speed can also be determined with a wind sock, a more accurate tool for measuring wind speed is the anemometer.
