What is indicated by the term "SKC" in a Terminal Aerodrome Forecast (TAF)?

The term "SKC" in a Terminal Aerodrome Forecast (TAF) stands for "sky clear." This designation indicates that there are no significant clouds or obstructions to the sky, which implies very favorable weather conditions for aviation. When "SKC" appears in a TAF, it reassures pilots and flight planners that the atmospheric conditions are suitable for flying, as clear skies reduce the risk of weather-related issues such as turbulence or poor visibility.

The presence of "SKC" means that visibility is likely to be good, and pilots can expect optimal conditions for takeoff, landing, and in-flight navigation. This is particularly important for visual flight rules (VFR) operations, where pilots rely on clear weather to fly safely.
