What is the most appropriate source to obtain weather information at your arrival time?

The Terminal Aerodrome Forecast (TAF) is designed specifically to provide weather information for airports and aerodromes for a specified period, typically covering 24 to 30 hours. It includes forecast details on wind, visibility, significant weather events, and cloud cover. Because TAFs are updated regularly and tailored to a specific location, they offer valuable insights for pilots regarding expected weather conditions during their arrival.

In contrast, an Aerodrome Weather Report (METAR) provides current weather observations at a specific location, which is useful for understanding existing conditions but does not predict future weather. The Area Forecast (FA) gives broader meteorological information about larger regions and may not contain localized data required for arrival decisions. The Predicted Weather Analysis (PWA) offers a forecast analysis but can be less precise than TAFs for particular airports. Therefore, the TAF is the most appropriate choice for anticipating weather conditions at the time of arrival.
