* The Gulf of Mexico is a much smaller body of water than the Atlantic Ocean. This means that there is less water to generate waves.
* The Gulf of Mexico is located in a more sheltered area than the Atlantic Ocean. It is surrounded by land on three sides, which helps to block waves from forming.
* The Gulf of Mexico has a shallower continental shelf than the Atlantic Ocean. This means that waves lose energy as they travel over the shallow water.
As a result of these factors, the waves in the Gulf of Mexico are typically smaller than those in the Atlantic Ocean. However, there are still some areas of the Gulf of Mexico where waves can get quite large, such as during hurricanes.
