In addi- tion, the base heights of these low clouds are lower over the ocean; this is likely due to the higher humidity at the water surface.

Why is there sometimes no clouds in the sky?
Even when it is very warm and sunny, there might not be any clouds and the sky is a clear blue.

Nearly 70 percent of Earth’s surface is covered by clouds at any given time. While cloud cover can obscure the surface and frustrate satellite imagery of land and sea, clouds offer a beautiful glimpse of our atmosphere and its processes.
What percentage of the sky is cloud free?
Over land, 30 percent of skies are completely cloud free. Earth’s cloudy nature is unmistakable in this global cloud fraction map, based on data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite.
Why do we see clouds?
