How is wind direction indicated in a TAF?

Wind direction in a TAF (Terminal Aerodrome Forecast) is indicated in degrees from true north. This is the standard measurement used in aviation to provide precise and unambiguous information about wind conditions. The convention of using degrees allows pilots and meteorologists to accurately interpret and use the data for flight planning and operations.

Using degrees from true north means that a wind direction of 090 degrees indicates wind coming from the east, whereas 270 degrees indicates wind from the west. This numerical format is critical for air navigation as it standardizes communication across different regions and ensures clarity in operational contexts.

Other methods, such as using compass points or cardinal directions, can be less precise and might not provide the necessary detail for aviation needs. Nautical miles, while a unit of distance used in maritime and aviation contexts, are not relevant for indicating wind direction and therefore do not apply here.
