What is a TAF?
TAF is the international standard code format for terminal forecasts issued for airports. The acronym translates to Terminal Aerodrome Forecast and is analogous to the terminal forecast (FT) coding format currently used in the US. Aviation terminal forecasts serve the pre-flight and in-flight meteorological service requirements of aviation operations by providing a forecast of weather conditions at an airport. It is the policy of the FAA and ICAO (International Civil Aviation Organization) that terminal forecasts shall be prepared, issued, and distributed on a timely basis in a code format designed by the World Meteorological Organization (WMO) for both domestic and international use.
