The tides aren't very big on Sunday, there is typically a 2 day delay after a full moon. So taking Newquay as an example, Sunday's tide is 7.3m, by Tuesday it's 7.7m.

While 7 meters is high for some, I don't remember it as exceptional for British Waters. Any idea how high they get in any infamous North Sea storms?

Thought as much:
