An incredible phenomenon seen in very few parts of the world, tidal bores are formed as tidal waters flow into outgoing rivers. As the 100 billion tonnes of water rushes into the Bay of Fundy at high tide, there is only so much space and therefore the great tides actually reverse the flow of rivers that would typically flow into the Bay.
Within the Bay of Fundy tidal bores can be found in three locations: Petiticodiac River, Salmon River and Shubenacadie River.
Perhaps the most popular location for viewing the tidal bore in near Maitland, Nova Scotia, on the Shubenacadie River. The tidal bore here will reverse the outgoing river and send it almost 40 km backwards. The tidal bore wave can range in height from just one foot to over ten feet of water, depending on channel conditions as well as the lunar cycle. Its speed can reach up to 12 km an hour and can be heard well before it is seen. During each tide cycle – therefore twice every day – between eight and ten sets of these natural sand rapids occur and each set lasts for approximately 15 minutes (Shubenacadie River Runners/Tidal Bore Rafting Park & Cottages, 2011).
To truly experience the tidal bore phenomenon – upclose and personal – set out on an unforgettable, exhilarating Zodiac adventure with Shubenacadie River Runners or Tidal Bore Rafting Park & Cottages and ride the tidal bore on its crest. Following this thrilling ride, sit back and take in your surroundings as your captain returns you safely to shore; spot bald eagles soaring overhead and learn more about the incredible, natural force of the Bay of Fundy and some interesting historical tidbits.
