A single large cumulus cloud fills the center of the picture. It is built from rounded, sculpted masses in warm cream and ivory, with soft grey shadows underneath. Smaller clouds drift along the lower edges and the right side.

The blue sky around it is worked in visible, swirling brushstrokes that vary from dusty slate to brighter cerulean. The composition has no horizon or landscape, so the clouds are the whole subject. The effect is calm and open, like an old plein-air sky study.
