For how long are TAFs valid?

Terminal Aerodrome Forecasts (TAFs) are aviation weather forecasts specifically designed for the needs of pilots, providing critical information about the weather expected at an airport during a specific time frame. TAFs are typically issued for a 24-hour period, with the forecast covering weather conditions expected during that time.

This 24-hour validity period is essential because it gives pilots enough lead time to plan their flights thoroughly, considering weather changes that might affect safety and operational effectiveness. The forecasts can be updated or amended as necessary, depending on evolving weather conditions, which emphasizes the importance of being current with the latest TAFs during flight planning.

Understanding the specific duration of TAFs is vital for flight planning and ensuring readiness for potential weather impacts during the intended flight segment.
