Quick Answer

The Bay of Fundy between Nova Scotia and New Brunswick, Canada, has tides exceeding 16 metres.

The Full Story

The Bay of Fundy, located between the Canadian provinces of Nova Scotia and New Brunswick, experiences the world's largest tidal range, with spring tides that can exceed 16 metres (about the height of a five-storey building). The bay's funnel shape, resonant length, and natural oscillation period of about 13 hours (close to the tidal cycle of 12.4 hours) amplify the tides. At low tide, vast stretches of seabed are exposed; at high tide, the water rushes back in a dramatic transformation.

Key Facts

1.About 160 billion tonnes of water flow in and out of the bay each tide cycle.
2.The highest recorded tidal range at Burntcoat Head was 16.3 metres.
3.The bay is a critical feeding ground for migratory shorebirds, including semipalmated sandpipers.
