Change from light to dark in 30 minutes

Threatening skies. One minute blue, changes to grey, then more wisps of blue. A rainbow appears. And the sky changes to grey and heading for black.

But the water is calm, warm too. Simply fantastic swimming in those waters.

Within 40 minutes the sky has changed from pure blue to jet black. The whole countryside has changed from bright joy to dark foreboding.

Typically Irish.
