Key West is a small island at the southernmost tip of Florida. It is surrounded by the Atlantic Ocean and the Gulf of Mexico. The island's flat terrain allows winds to flow freely. This leads to a relatively stable atmospheric pressure. The open waters surrounding the city also moderate temperature and humidity.

The proximity to the equator means the sun's rays strike the island directly. This leads to a high amount of solar radiation. The radiation heats the air, causing it to expand and rise. This creates a low-pressure system. The surrounding ocean waters cool the air, counterbalancing the effect.

The result is a relatively stable atmospheric pressure in Key West. The pressure rarely drops below 29.80 inches or rises above 30.20 inches. This stability contributes to the city's pleasant subtropical climate.
