Click on the 'Predict' button (third button down) which will prodice a weeks worth of tidal data.
To calculate slack water, deduct 4 hours from the HW time or add 3 hours to the HW time.
For example, HW is 14:22.
Therefore slack water is:
14:22 - 4:00hrs = 10:22 in the morning and
14:22 + 3:00hrs = 17:22 in the afternoon.
Please carefully check all times personally as we cannot be held responsible. Actual slack duration varies depending on tide state - Springs or Neaps - as well as weather conditions. Contact the shop on 01243 601000 for latest info.
