In a Terminal Aerodrome Forecast (TAF), wind direction is measured in degrees True. This is crucial for pilots as it provides a consistent reference for understanding the wind relative to their flight path. Using degrees True allows for the accurate assessment of how wind will affect aircraft performance and navigation, regardless of the local magnetic variations.

Utilizing degrees True ensures that pilots can use the wind information effectively without needing to make additional calculations for magnetic declination, which can vary by location. This standardization is essential for flight planning and safety, as it helps pilots maintain a clear context of environmental conditions they are facing during their flight operations.

When wind direction in TAFs is reported, the degrees are rounded to the nearest ten degrees, which further aids in the simplicity of interpreting the information quickly. Other measures like radians are not used in this context, as they are more common in mathematical expressions rather than aviation meteorology.
