How often are METAR reports typically updated?

METAR reports are typically updated every hour. This regular issuance is vital for ensuring that pilots, meteorologists, and other aviation-related personnel have the most current and accurate weather information. The hourly updates provide real-time observations of weather conditions, including temperature, wind speed and direction, visibility, cloud cover, and significant weather events.

Although there are situations where METAR reports may be updated more frequently, such as during rapidly changing weather conditions or for special flight operations, the standard practice remains an hourly update. This frequency helps maintain a standardization across airports and weather stations, allowing for consistent data availability for planning and safety in aviation operations.
