Get to know the world’s highest tides

Twice a day, 100 billion tonnes of seawater flows in and out of the Bay of Fundy’s Minas Basin. This makes the Bay of Fundy home to the world’s highest tides, where the average tide range can reach 12 metres and sometimes, up to 16 metres!

The high tides of the Bay of Fundy are primarily influenced by two factors: astronomical factors and the unique shape of the Minas Basin. The height of the tides varies from day to day, depending on the strength of the gravitational pulls from the sun and the moon. Visit the Bay of Fundy during a full moon cycle, and you’ll witness the reason why the tides stand as being the world’s highest.

Due to the Minas Basin’s unique shape, the body of water entering the Bay of Fundy gradually becomes constricted which causes the water to rise. Picture a small child getting pushed on a swing. With each push, the child goes higher and higher. The pulse of the Atlantic Ocean, its lunar tide, is that extra push which makes the tides even higher.
