Fundy National Park of Canada

High and Low Tides

In the Bay of Fundy you can see two high and two low tides each day. The time between a high and low tide, on average, is six hours and 13 minutes.

If you come back to the same place two or three days in a row, you will notice that the water is at its highest and lowest about an hour later each day. This is because the tides work on a "lunar" or moon day which is 24 hours and 52 minutes long. While the earth is turning on its axis the moon is orbiting in the same direction around the earth and it takes one day and 52 minutes for a point on the earth to reappear directly beneath the moon.
