The Petitcodiac River’s claim to fame is its tidal bore, forming twice a day as the tides from the Bay of Fundy push up river towards Moncton. Depending on the amplitude of the phenomenon, the wave in the Petitcodiac River will vary today from a few cm in height to as much as 75 cm ( as high as 2 m before the construction of the causeway), and at speeds ranging from a few km/hour to 13 km/hour.
A tidal bore occurs in areas of the world where tidal amplitudes are strong, as is the case with the Bay of Fundy region. The phenomenon is created and influenced by a number of factors including river slope, downstream flow, river basin morphometry, moon phases, seasons and winds. The accompanying wave or vertical front moves upriver on the incoming tide, channeling itself into a narrower body of water such as the Petitcodiac River.
Depending on the amplitude of the phenomenon, the wave in the Petitcodiac River varies today from a few cm in height to as much as 75 cm (formerly as high as 2 m), and at speeds ranging from a few to 13 km/hour. With the opening of the causeway in 2010, the tidal bore is slowly regaining its former glory.
In the summer of 2013, surfers from all over, eager to surf the newly restored tidal bore, attracted thousands of spectators to the riverfront. As a result, many international surfing magazines featured Moncton as a new surfing destination.
The Fundy Biosphere Initiative, an organization that works in synergy with local communities, conservation groups, natural resource sectors, tourism organizations and academicians have recently identified Moncton’s Bore Park and the Tidal Bore as one of their Amazing Places to visit in the Fundy Biosphere Reserve.
This watershed reserve adjacent to the upper Bay of Fundy is recognized by UNESCO and covers an area of 440,000 hectares stretching from St. Martins, around Moncton, including almost all of Albert County, to the Tantramar Marsh near Sackville. http://fundy-biosphere.ca/en/experience/amazing-places/tidal-bore
