How often are METAR reports typically issued?

METAR reports are typically issued every hour, which is standard practice for providing current weather information relevant to aviation. This hourly issuance allows pilots, air traffic controllers, and meteorologists to stay informed about the latest conditions at airports and for flight planning.

While there may be times when special METAR reports are issued more frequently, especially during significant changes in weather or when specific conditions warrant, the routine reporting is done on an hourly basis. This ensures that the data remains relevant and useful, helping to maintain safety in air travel. Other frequencies, such as every 30 minutes or every 15 minutes, are not standard practices for routine METAR reporting, serving specific needs rather than the broader operational requirements of aviation.
