Re: surge forecasting is not a perfect science

It's kind of confusing to convey too. I know there's reasons for some of the various datums they have, but it makes it confusing when different ones are used. And each station has ones that relate to that station as it depends on its tides.

NHC uses:

MHHW*
Mean Higher High Water
The average of the higher high water height of each tidal day observed over the National Tidal Datum Epoch. For stations with shorter series, comparison of simultaneous observations with a control tide station is made in order to derive the equivalent datum of the National Tidal Datum Epoch.
