The tides in the Bay of Fundy are most impressive, something that we don’t get to see in the Midwest.
Nova Scotia and the Bay of Fundy have some of the highest tides in the world and something that I think is very interesting to observe. I was able to see a 48 foot tide.
Another tidal phenomenon is the tidal bore where rivers actually change direction as a wave front moves up the river. There is a Tidal Bore at Truro Nova Scotia where you can watch a wave come up the river and the river flow change directions.
There are several factors that influence the tides but in simplified terms, and highest high tide and lowest low tide occur on the same day and that occurs on or about the new and full moon phases.
Two weeks later, during the first or third quarter phases, the tidal range is the lowest--- lowest high tide and highest low tide.
With basically two high and two low tides a day your viewing time needs to be over six hours for a complete transition. Find a dock where there will be a big change in the tide and stay there for at least six hours to watch the water level change. There is such a dock near Blomidon Provincial park. It is fun to watch the boats go from dock level to resting on the muddy bottom with their decks many feet (10-20) below the dock.
The Bay of Fundy is certainly more impressive during times of greatest tidal range. I always tried to plan my Nova Scotia trips based upon the tide tables. If you still in the planning stages, try to be in Nova Scotia during a Full moon or a New moon to get the tides of highest range.
