The Bay of Fundy is dominated by the highest tides in the world.  Each day there is a solar high tide and a lunar high tide as well as a solar low tide and a lunar low tide.

High and low tides do not occur at the same time each day, every high tide is approximately 12hrs and 25 minutes later than previous one. This means that from day to day high tide occurs about 50 minutes later than the corresponding tide the previous day.  The height of tides will vary as well as the time, in some areas the difference between the highest high tide and the lowest low tide can be up to 2m or more with the "spring tides " usually being the highest. The term "spring tide" does not refer to the season but to a tide that is abnormally high due to the alignment of the moon and the sun.

The powerful tides not only effect our coastline and shore but also impact on the larger rivers that flow into the Bay. An incoming tide will cause water levels to rise at a quicker rate than they will recede. The force of this incoming rush will cause rivers to meander and will transport large amounts of material back and forth. High tides especially will cause the river to flood and deposit this material as the water level retreats, effecting salt marshes or forming mud flats.
