Turner has applied translucent washes of watercolour in broad, gestural strokes to set out the basic arrangement of this Folkestone beach composition. The obscure outline of a headland is visible in the distance. It is summarily rendered with swift lines and dots of purple and with grey wash applied with a dry brush lending it a mottled appearance. Faint, vertical dry-brush strokes at the right could possibly suggest sea grasses of some sort. Turner has applied a very thin layer of grey wash for the overcast sky. Rainfall is evoked above the headland where the wash has dragged against the grain of the paper.
Some of the watercolour continues onto the opposite page and appears to have also offset onto this page.
