What time period does the forecast in the METAR typically cover?

The forecast provided in a METAR typically covers a time period of one hour. This is important for pilots and aviation professionals as METAR reports are updated regularly, typically every hour, and provide current weather conditions at an airport or weather station. This data includes information such as wind speed and direction, visibility, weather phenomena, and temperature, allowing for real-time decision-making for flight operations.

In contrast, options that suggest longer time periods like six, twelve, or twenty-four hours refer to different types of weather reports or forecasts, such as TAF (Terminal Aerodrome Forecasts), which can cover longer durations. Understanding the scope and purpose of METARs is crucial for interpreting how weather may impact flying within the immediate short term.
