What is the maximum duration of a TAF forecast?

The maximum duration of a TAF (Terminal Aerodrome Forecast) is 30 hours. TAFs are specifically designed to provide forecast information for aviation operations, particularly for airports and aerodromes. These forecasts focus on significant weather conditions that could impact aircraft operations, including wind, visibility, and precipitation.

A 30-hour duration allows for comprehensive coverage of expected weather changes that could affect flights, ensuring that aviation users have relevant information to plan their routes and manage potential weather-related disruptions. TAFs are issued at regular intervals, typically every six hours, and the 30-hour timeframe ensures that users can receive timely forecasts for planning purposes without being overwhelmed by too much data.
