We walked Dún Laoghaire pier before 9 and were rewarded by the diving of gannets and terns into the slack tide.
The mean tidal range in the harbour is about 3 m while the difference between the lowest and highest astronomical tides is recorded as 4.7 metres. An amazing feat of engineering, this was in 1842 the largest man-made harbour in western Europe.
Then I moved a few kilometres south to watch people fishing from Dillons Park. Constant change is the reality of living by the sea.
On the pier, little fish were clearly visible in the lowest water of this spring tide. The terns flew in the shadow of the pier to avoid detection. A gannet came into the harbour after a yacht sailed out.
At home in the garden, a lens and camera change for some macro photography before the forecast storm might strip the plants of flowers and leaves. And there came a journey to a socially-separated lunch among the chickens, ducks, bees, pigs and grandchildren down on the farm.
