What does tidal range affect?
The greater the tidal range the more effect this phenomenon has on the coast. The slope of a beach or other coastal landform also is important however because a steep cliff provides only a nominal change in the area over which waves and currents can do their work even in a macro-tidal environment.

Why is there no tide in the Caribbean?
Most of the Caribbean islands are really islands out in the ocean with not so much topography to alter the way the tidal bulge is distributed. Channels between island will routinely see higher currents than surrounding areas because more water has to get between the islands to normalize the height.
