The answer is - wavelength.
As the wave approaches the shore and it reaches shallow waters it's characteristics start to change. When the wavelength is half of the water depth than the bottom of the wave starts to drag on the ocean floor. As it starts to do this the wave starts to slow down at it bottom as it approaches the beach but the upper part of the wave maintains its initial speed. Because of this the wave becomes longer. Once it reaches the shore it crashes on it and falls apart.

The hurricanes have negative, often devastating effects on the Caribbean and Central America.
Explanation:
Both, the Caribbean an Central America, are located in areas where there is high hurricane activity. These two regions are not well developed, but instead they are developing, and there is large scale poverty, which unfortunately doesn't go well in a combination with the hurricanes. Every year, several hurricanes of varying sizes hit these regions, and the effects are devastating more often than not.
Because the people are poor in general, as well as the countries themselves, the infrastructure is of very bad quality. The systems for warning are either non-existent or not very efficient. When stronger hurricanes hit these two regions suffer badly as most of the infrastructure gets destroyed. The bad organization results in lot of people ending up without any help or with little to no medical assistance. Hundreds of thousands of people every year end up homeless, badly injured, or dead, and part of the reason for that is that the warning systems often don't work properly and don't notify the people on time to take cover in safer grounds.
Some of the countries that often have huge problems because of hurricanes are:
- Haiti
- Dominican Republic
- Belize
- Cuba
