Mariners should also be aware that the increased tidal ranges will also affect the low water period and subsequently the available water over these periods is predicted to be much less than on normal spring tides. In addition to the enhanced tidal range there will also be a risk of increased tidal flows.
Weather conditions will continue to play a dominant role in whether tides meet predictions, therefore mariners are advised to pay particular attention to observed heights especially during low water periods where there may be a risk of a negative tidal surge.
The dates where the most notable high tides are expected are:
27th – 30th September 2015
27th – 30th October 2015
25th – 27th December 2015
11th – 14th January 2016
