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 2020 - 30 June 2021. The number of years of data analysed is also shown. Any difference between the period of observations and number of years analysed indicates data missing for one or more years.
