Which METAR code indicates sky clear?

Which METAR code indicates sky clear?

• A. FEW
• B. SCT
• C. SKC
• D. OVC

Answer: (C)

METAR reports use octas to describe how much of the sky is covered by clouds. Zero octas means there are no clouds at all, which is indicated by SKC. So SKC communicates that the sky is entirely clear. The other codes describe some cloud cover: FEW is a few clouds, SCT is scattered, and OVC is overcast. Therefore, SKC is the code that means sky clear.
