Burntcoat Head, Bay of Fundy (Canada) — The tidal range of Minas Basin in Nova Scotia is 17 m (55.8 ft). A record spring tide of 21.6 m (71 ft) was reportedly observed on Oct. 4-5, 1869, during a tropical cyclone named the Saxby Gale. Each tide cycle (12.4 hours) of 115 billion tonnes of seawater in the Bay of Fundy is more than the combined flow of all of the world’s freshwater rivers. In Mi’kmaq First Nation folklore, the huge tides are caused by a giant whale.
Leaf Basin, in Nunavik’s Ungava Bay (Canada), has a 16.8 m (55.1 ft) tidal range.
