How often are TAFs published?

How often are TAFs published?

• A. Every hour
• B. Every 6 hours
• C. Every 12 hours
• D. Every 24 hours

Answer: (B)

TAFs are published every six hours. This four-times-a-day cadence provides a practical forecast window of about 24 hours for a given airport, giving pilots and planners timely updates while keeping the forecast stable enough to be useful. TAFs are specifically designed for planning and flight operations, complementing hourly METAR observations with a forward-looking forecast. Amendments (such as AMD) can be issued when significant weather changes occur between cycles, but the standard schedule remains every six hours.
