What is the frequency at which METAR reports are typically generated?

METAR reports, which provide essential weather information for pilots, are typically generated every hour. This regular interval ensures that pilots and air traffic controllers have access to up-to-date meteorological data, which is crucial for flight safety and planning. The hourly frequency allows for the monitoring of changing weather conditions, particularly at busy airports where rapid weather changes can significantly impact operations. While some special reports may be issued if conditions change significantly (like a sudden storm), the standard generation of METARs remains on an hourly basis, making it a reliable source for current weather information in aviation.
