What is a TAF?

A TAF, which stands for Terminal Aerodrome Forecast, is specifically designed to provide weather information relevant to the needs of aviation at airports. It typically offers a forecast for a period of up to 24 hours, with updates every six hours, but can also include expected conditions up to 30 hours in some cases. This makes it essential for pilots and air traffic control to assess flying conditions, including visibility, wind, precipitation, and significant weather events, which all play crucial roles in ensuring safety during flight operations. Thus, the definition aligns closely with the characteristics of a surface conditions forecast, reflecting the practical application of TAFs in real-world aviation scenarios.
