Wind direction is a primary concern for boats and yachts coming in and out of seaports & marinas, such as commercial ports or cargo ports, to help them maneuver in and out of slips and to dock at the right angle to avoid collision or damage. In severe wind conditions, boats can be blown to collide with each other or with other objects in the marina, causing safety issues and damage.

Wind direction is also critical information at large commercial ports, where ships and barges arrive and depart with commercial cargo to be lifted by crane on or off the vessels. Weather conditions can make it difficult for crane operators and port personnel to maneuver the cargo safely on and off the carriers without damage or injury.
