Oil on mdf board, 24 x 30 cm. High tide at Porthcurno Bay in Cornwall during a squall. Catches the moment when the secondary wave fights its way up the beach against the strong drag of the water draining back (Undertow) from the preceding major wave (usually the 7th -10th wave is the biggest). Painted from sketches on site and photo. Great Place to get wet whilst painting! Where did the cormarant go?
