Temperature and dew point are reported in the body of the METAR/SPECI report in what unit?

Temperature and dew point in METAR and SPECI reports are reported in whole degrees Celsius. This is the standard used in aviation weather reporting worldwide, aligning with international meteorological practices. Whole degrees Celsius provides a clear and straightforward representation of temperature and moisture levels.

Using degrees Celsius allows for easier interpretation and is essential for pilots and meteorologists who require precise and consistent weather information. The adherence to this unit of measurement across various reports ensures uniformity and helps maintain safety in aviation operations.

While other measures, such as tenths of a degree Celsius, are common in different contexts or meteorological studies, the established protocol for METAR and SPECI specifically utilizes whole degrees Celsius to convey temperature and dew point values. This distinguishes it from those other formats and aligns with global meteorological standards.
