Seen here are Cumulus congestus, narrow tower shearing, and patches of Altocumulus and Cirrostratus, with a partial 22° halo and a parhelion coming from the latter. A few Cirrus elements and a layer of haze (close to the ground) are illuminated by the low Sun.

Cumulus clouds are generally dense with sharp outlines, developing vertically in the form of rising mounds, domes or towers. Cumulus are normally detached clouds; while it is not possible to determine if these clouds are detached in this image, shadows on the sea just beyond the coast suggest a degree of separation of the main cells. They also have the characteristic very bright white sunlit parts; relatively dark and nearly horizontal base; and strong vertical extent associated with Cumulus. Significantly, the strong sprouting with sharp outlines and bulging upper parts that resemble a cauliflower at 4 and 5 determine the species to be congestus.
