Storm surge = difference between measured water levels and elevation of the astronomically predicted tide
Maximum height reached by storm surge is affected by (1) phase of tide at time of the surge and (2) stand of local mean sea level for that time of year

Different forms of measurements (referenced in section on Storm Surges analysis)

  • MLLW – Mean Lower Low Water = the average of the lower low 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.
  • MHHW – Mean Higher High Water = the average of all the high water heights 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.
  • MSL – Mean Sea Level = The arithmetic mean of hourly heights observed over the National Tidal Datum Epoch. Shorter series are specified in the name; e.g. monthly mean sea level and yearly mean sea level.
