Bay of Fundy Tides

Stretching between New Brunswick and Nova Scotia on Canada’s east coast, the Bay of Fundy is truly one of the country’s most extraordinary natural wonders and attracts an average of a million nature tourists every year.

The average tidal range of all oceans around the globe is 1 meter (3ft), so how can the tidal difference in the Bay of Fundy reach up to 16 meters? This tidal phenomenon exists because the bay has a few distinct features: a substantial amount of water and a unique shape and size that causes resonance.

One hundred billion tonnes of sea water flow in and out of the Bay of Fundy twice daily – more water than the combined flow of all the world’s fresh water rivers.

Fundy’s extreme tides create a dynamic and diverse marine ecosystem. The Bay is renowned for its coastal rock formations, extreme tidal effects (vertical, horizontal, rapids and bores) and sustainable coastal development. It is also a critical international feeding ground for migratory birds, a vibrant habitat for rare and endangered whales, and one of the world’s most significant plant and animal fossil discovery regions.

The Acadia Tidal Energy Institute (ATEI) was established in 2010 following 100 years of interest and study on the potential and implications of tidal power development in the Bay of Fundy. The Institute focuses on tidal energy resource assessment, environmental impacts and socio-economic factors.
