Saint John Bay of Fundy has the Highest Tides in the World

The Bay of Fundy, Saint John, New Brunswick, Canada - the highest tides in the world
The Moon effects the Tides (and other watery things like our emotions and bleeding)

100 billion tons of seawater flows in and out of the Bay of Fundy during one tide cycle - more than the combined flow of the world's freshwater rivers.

We went to Reversing Falls.

The Bay of Fundy has the highest tides in the world. The Bay of Fundy faces southward, so the rushing ocean tides enter it like going into a funnel. The farther up the Bay of Fundy the water goes, the more it gets squeezed by the sides, which get more narrow, and the bottom, which gets more shallow. Then the low tide running out, confronts the high tide coming in.

According to the Bay of Fundy website, the Bay of Fundy tides are from tidal action originating in the Southern Indian Ocean, sweeping around the Cape of Good Hope and then northward.

They are also affected by the distance of the moon from the earth at this longitude.

At Saint John, the tides rise 28 1/2 feet. We observed this right in front of the pulp mill (mentioned below).

According to the Bay of Fundy website,

"When the tide is low, the St. John River, 450 miles long, empties into the bay. Between Fallsview Park and the Pulp Mill, the full flow of the river thunders through a narrow gorge. An underwater ledge, 36 feet below the surface causes the water in the river to tumble downward into a 175-200 foot deep pool. Below the mill and under the bridge. The water then boils in a series of rapids and whirlpools.

"As the bay tides begin to rise, they slow the course of the river and finally stop the river's flow completely. This short period of complete calm is called slack tide. It is only at this time that boats are able to navigate the Falls. Shortly after this slack tide the bay tides become higher than the river level and slowly, at first, the river begins to flow upstream. As the bay tides continue to rise, the reverse flow gradually increases and the rapids begin to form, reaching their peak at high tide. "
