The previous afternoon the weather was similar. . .

a light swell is coming off the Atlantic.

Waves are in motion, just visible, moving towards us across the surface of the water – at speed.

The actual water they pass through is barely changing position, describing small, slow, circular, vertical orbits.

Finally, almost at the last moment, a small section of a wave is cut off  by the rocks-  guided into a gully.

Forced into the tight space, it loses speed as it drags against the sides. But it retains its energy.

Thus gaining height, it trips over itself, breaking on some underwater obstruction.

And now it is the water itself  – (at a ton per cubic metre), that is surfing down the face of the wave, accelerating towards us.

In speeding up, it quickly reaches its end, dashing itself with abandon on the Breakwater – while, a few seconds later, the rest of the wave, still in the freedom of comparatively open water only a few feet away, rolls sedately up the stones.

And here, it is lifted by the swell above the surrounding sea, only to sluice downhill across the rocks, seeking balance with the main body of water.
