What does a METAR report indicate if wind direction varies 60 degrees or more?

A METAR report serves as a crucial tool for pilots and those involved in aviation, providing essential weather information. When the wind direction varies by 60 degrees or more, the term used to describe this phenomenon is "variable." This indicates that the wind is not coming from a consistent direction, which could have implications for flight operations, including takeoff and landing procedures.

Understanding wind variability is essential for pilots as it affects aircraft performance and navigation. A variable wind can present challenges, particularly during critical phases of flight. This contrasts with stable wind conditions where the direction remains relatively constant. Therefore, when faced with significant fluctuations in wind direction, identifying it as variable allows pilots to prepare adequately for potential impacts on flight safety and maneuverability.
