Canadian Tide and Current Tables

Volume 1

Available for purchase from an authorized chart dealer.

Tide Tables provide predicted times and heights of the high and low waters associated with the vertical movement of the tide. The Current Tables provide predicted times for slack water and the times and velocities of maximum current, all of which are associated with the horizontal movement of the tide. Short term predictions are available online.

Prediction

The tide predictions are available in table, graphic and text formats for over seven hundred stations in Canada. The hours and heights of the high and low waters and also the hourly water levels for seven days are available. The period can be modified if needed with the help of boxes reserved for the matter in the left margin.

The predicted hours correspond to the time zone of the locality for the year period. The time zone can be modified if needed. The predictions are also available in universal coordinated time (UTC).

Meteorological conditions can cause differences (time and height) between the predicted and the observed tides. These differences are mainly the result of atmospheric pressure changes, strong prolonged winds or variations of freshwater discharge.
