How frequently are TAFs issued?

TAFs, or Terminal Aerodrome Forecasts, are issued every 6 hours for the majority of airports, which translates to a total of four times daily. This frequency ensures that pilots and aviation personnel have up-to-date information about expected weather conditions at specific airports within a 24-hour period. The general forecast period for TAFs is 24 hours, and for selected airports, they might issue TAFs for up to 30 hours. The reason for this schedule is to provide timely and relevant weather updates that are critical for flight planning and safety. The issuance every 6 hours reflects the dynamic nature of weather patterns that can change, making it essential for pilots to have the most current data available to make informed decisions about flight operations.
