BAY OF FUNDY TIDES: THE HIGHEST TIDES IN THE WORLD!
Twice everyday the bay fills and empties of a billion tonnes of water during each tide cycle—that’s more than the flow of all the world’s freshwater rivers combined.

How High are the Fundy Tides?
Low Tide in the Bay of FundyThe Bay of Fundy has the highest tides in the world, and those enormous tides alone make that the Bay of Fundy is one of the world’s greatest natural wonders.

The height of the tide difference ranges from 3.5 meters (11ft) along the southwest shore of Nova Scotia and steadily increases as the flood waters travel up the 280 km (174 miles) of shoreline to the head of the Bay where, in the Minas Basin, the height of the tide can reach an incredible 16 meters (53ft).

Tides cause the ocean to rise and fall twice each day. But what exactly causes high tides and low tides?
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another.

Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see Timing). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude tides a day—is a third regular category.
