Port of Spain is a coastal city. It is surrounded by the Northern Range mountains to the north. The Gulf of Paria lies to the west. The city's location affects the atmospheric pressure. The mountains block winds from the north, causing air to rise. This creates high pressure.

The landscape also affects the flow of air. The Gulf of Paria brings in moist air from the ocean. This air rises when it meets the mountains. As it rises, it cools and condenses, forming clouds. This process affects the barometric pressure.

The pressure changes cause different weather patterns. High pressure brings clear skies and dry air. Low pressure brings cloudy skies and rain. This is why Port of Spain experiences a tropical savanna climate.
