One week is the interval between max and min, when it comes to tides.
Just what exactly are you refering to?

There was an unusually high series of springs a week or two ago due to the
Moon being at perigee and in line with the Sun on the Sun side of the Earth.
High highs were extreme and up to two feet above normal tidal range. Not a
good time to run aground.
