What is the coverage radius for a TAF?

The coverage radius for a TAF, or Terminal Aerodrome Forecast, is established at a 5 statute mile (SM) radius from the reporting station. This distance encompasses the area in which the forecast is deemed to be most applicable and where pilots and operational teams can expect weather conditions to affect operations. TAFs are primarily created for airports and relevant aerodromes, providing crucial information on expected weather conditions for flight operations within that specific radius. By using a 5 SM radius, it ensures that the forecast is relevant to the immediate area surrounding the airport, capturing significant weather impacts that could affect takeoffs, landings, and flights in the vicinity.
