<P> Traditional Mi'kmaq folklore states that the tides in the Bay of Fundy are caused by a giant whale splashing in the water . Oceanographers attribute it to tidal resonance resulting from a coincidence of timing : the time it takes a large wave to go from the mouth of the bay to the inner shore and back is practically the same as the time from one high tide to the next . During the 12.4 - hour tidal period , 115 billion tonnes of water flow in and out of the bay . </P>
