Why are the tides in the Bay of Fundy so large?
The Bay experiences a natural tidal funneling effect (and sloshing effect, known as a seiche) which causes tidal ranges of over 10-15 meters. The seiche has a period of 13 hours (780 minutes), which corresponds almost exactly with the lunar tidal cycle of the Atlantic (745 minutes), creating resonance conditions that the tidal flow amplifies the seiche, causing the highest tides in the world.
