The annual companion book for the Canadian Hydrographic’s Current Atlas makes it easy to use – just look up the month, day and the hour, and you will be given the appropriate page in the Atlas. The Tables list every hour of every day and are corrected for Daylight Savings Time. Waggoner Tables and Canadian Hydrographic’s Current Atlas (can be purchased here) help you to understand the details of the currents around the San Juan and Gulf Islands and up the Strait of Georgia as far as Campbell River. With these two books you can judge what the currents will be for your cruise and adjust accordingly.
