Went whale watching last Wednesday on Bay of Fundy, located between Nova Scotia and New Brunswick just north of Maine. Very nice day 70F. no wind or waves water temperature 55F. The difference between high and low tide is 43 ft. The water flow in a 12 hour tide cycle is 100 billion tones of water or more than twice the flow of all rivers in the world. The tide is so high that the St John River will flow backwards on the high tide. We saw 4 different humpback wales, blue heron, minke whale, seals and porpoises.
