Charts & Tides

Introduction to Tides

Tides are the alternating rise and fall of the surface of the seas and oceans. They are due mainly to the gravitational attraction (pull) of the moon and sun on the rotating earth. Two high and two low tides occur daily around Britain and, with average weather conditions, their movements can be predicted with considerable accuracy . . . . ”

Tidal Conversion Table

Please note that these conversion tables are average and are therefore only an approximate guide. More accurate times should be acquired from Tide Tables. The conversions listed are applied to the times given in the Calendar for Dover. Thus for Falmouth - 0612 means that high water occurs, on average, 6 hours 12 minutes before High Water Dover.

The duration is the approximate time of Low Water before the High Water listed. For Dover Low Water will therefore be about 5 hours 5 minutes before the times of High Water Listed.
