About Tide Predictions

  • The times stated are in Standard Time (24 hour clock). During Daylight Saving Time (when in force) one hour needs to be added to the times stated.
  • The tide predictions for the Standard Ports are based on sea level observations, hence the tide needs to be estimated between the Standard Ports.
  • For Information on the Tide Gauges used to determine the tide predictions, please see the Tide Gauge Metadata. Access to monthly statistics of the sea level observations is also available via this link.
  • Please see the cautionary note regarding meteorological conditions and seasonal variations.
