What is the difference between a TAF and a METAR?

A TAF, or Terminal Aerodrome Forecast, provides a weather forecast specifically for the area around an airport for a set period, usually 24 or 30 hours. It anticipates expected weather conditions, such as visibility, wind, precipitation, and other meteorological phenomena that can impact flight operations. This forecast helps pilots and aviation personnel prepare for potential weather challenges during flight planning and operations.

On the other hand, a METAR is a routine aviation weather report that provides current meteorological conditions at an airport. This includes observations about temperature, wind, visibility, clouds, and significant weather phenomena occurring at the time of the report. METARs are typically updated every hour.

In summary, the distinction lies in the purpose and content of each report; a TAF forecasts future weather conditions, while a METAR reports on current conditions. Understanding this difference is vital for flight planning and ensuring safety in aviation operations.
