Even though Jamaica is commonly known to have a tropical marine climate, the truth is, the climate of Jamaica depends on where in Jamaica you are located. Why is this so? Well, Jamaicans experience two climates. If you are at the north eastern end of the island (windward side) you will experience a tropical marine climate, however if you are to the south western side (leeward wide) you will experience a semi-arid climate.
The Caribbean greatly impacts our climate. During the day, the sea is usually cooler than the land. Winds blowing from the sea will help to keep the land cool. In the night, the land loses heat quickly and becomes cooler. As a result, the nights are generally cooler than the day. Places that are closer to the sea coast will feel the effects of the sea breeze during the days.
