Standard port periods of observation

Find the period over which tidal observations were analysed to produce our tide predictions.

The following table indicates the years for which tidal observations have been analysed. The results of the analysis of that data have been used to generate tide predictions for the period 1 July 2022 to 30 June 2023. The number of years of data analysed is also shown. Any difference between the period of observations and number of years analysed indicates that data is missing for one or more years.
