After days of high winds and squally rain (official weather warnings from the Met Office), I set off for the beach prepared to find plastic debris from the storm. Instead, I found the inevitable band of seaweed at the high-water mark but no foreign bodies on the sand: only a beautifully disintegrating lobster pot and a dead gannet.

Once, several years ago, the beach at Cwm-yr-Eglwys was littered with goose barnacles which I have never found again.
Did I recommend the book Strands by Jean Sprackland? It’s all about what she finds on the beach over one year.
Strands sounds wonderful. I shall add it to my Christmas list – although I don’t really want to wait that long.
