How often are METAR reports issued?

METAR reports, which provide routine weather observations from airports, are issued every hour. This frequency ensures that pilots and other aviation personnel receive timely and relevant information about current weather conditions, enabling them to make informed decisions for takeoff, landing, and flight planning. The hourly reporting schedule helps maintain safety and efficiency in aviation operations, as weather conditions can change rapidly. Therefore, having up-to-date information is crucial for safe aircraft operations.

While there might be reports issued more frequently during significant weather events, the standard practice is to generate METAR reports on an hourly basis.
