What are TAF reports typically updated?

TAF reports, or Terminal Aerodrome Forecasts, are typically updated four times a day. These forecasts provide specific weather information for airports and are essential for aviation operations, including those involving unmanned aircraft. The scheduled updates occur at regular intervals, typically at 00, 06, 12, and 18 UTC. This ensures that pilots and operators have access to the most current and relevant atmospheric conditions, allowing for better flight planning and safety.

By providing updates every six hours, TAF reports can reflect changes in the weather that are critical for flight operations, including visibility and significant weather events within a five-mile radius of the aerodrome. Less frequent updates would not suffice given the dynamic nature of weather, particularly in regions experiencing rapid changes. In contrast, reporting every hour or weekly does not align with the needs of aviation, as conditions may require more timely adjustments in training and operational decisions.
