How often are METARs issued?

METARs, which are routine aviation weather reports, are generally issued every hour on the hour. This time frame ensures that pilots and meteorologists have up-to-date information about weather conditions crucial for flight safety and operations. The reports provide essential data regarding temperature, dew point, wind direction and speed, visibility, weather phenomena, and cloud cover, which can all change frequently.

While there are specific conditions that can lead to the issuance of special reports (SPECI) when significant weather changes occur, the standard hourly reporting schedule is in place to maintain a consistent and reliable flow of meteorological information. Such regular updates help ensure that pilots can make informed decisions based on the latest weather updates as they prepare for and conduct their flights.
