Low tide yesterday was at 1344 and this shows it just a few minutes afterwards at 1356. At that time it was only at 1.55m above chart datum (data from tidetables.org.uk) and was one of the lowest tides that I have noticed since I arrived. The kayaks really put it into perspective, showing how narrow the channel had become.
For comparison, the following high tide was at 1902, at 4.60m. It was getting dark by 1902 so this photo was taken at 1711, as the tide was coming in, at c.3.80m.
