How does one determine what the Mean Higher High Water (MHHW) is at a
specific location?

The answer seems very complex. Does this explanation suffice?

Calculating Operational MHW, MHHW, and MTL

Yeah, it's pretty complicated the way the USGS explains it (or doesn't!).

But the concept is a pretty simple one:  most locations have two high
tides per day.  The mean higher high tide is just the long-term
average height of the higher of the two daily tides.

Does that make sense...?

Hello researcher,
I surveyed some ground elevations in Puget Sound WA. I need to tie my
elevation data to a datum. I would like to tie them to the MHHW, but I
can't seem to find out what it is for Lynch Cove in Belfair, WA. Any
ideas?

This site:

http://students.washington.edu/dfinlays/pugetsound/bm1960_ll.tab

gives MHHW of 3.38 for Lynch Cove (search on the page for [ lynch ] to find it).

Is that what you need?
