How to have high tides in the tropics?

The Bay of Fundy sees the world's highest tides, with ocean water advancing and withdrawing as much as 20 meters or more within a single day.

Here is a list of the 50 tidal stations around the world with the highest tides, all with average tidal ranges of over 7 meters. Note the location of these tidal stations: they are in Canada, United Kingdom, Alaska, Argentina, France, Chile and Russia. None of these locations are anywhere near the tropics.

I want a great tropical river delta, like the Ganges delta, to empty into a sea with massive 10m or more tides. The river will collect waters from a wide swathe of savanna, and be highly seasonal in flow; a great monsoon season will increase flow rate by a factor of 10.

With the least amount of physical changes from Earth, how can I get 10 meter tides or more at a tropical river delta?

• I want the tides at this delta to be exceptional, so tides elsewhere on the planet must be roughly equivalent to Earth's.
