When cloud height and visibility values are halfway or less between two reportable values, which value should be reported?

Explanation:
Rounding to the nearest reportable value uses a conservative rule: if the observed value is halfway or closer to the lower of two reportable levels, report the lower value. This keeps reports consistent and avoids overstating favorable conditions for flight, since cloud height and visibility are published in discrete steps. For example, if the cloud base sits halfway between 2,500 ft and 3,000 ft, report 2,500 ft. If it’s closer to 3,000 ft (more than halfway), you would report 3,000 ft.
