Cayenne is located along the coast of the Atlantic Ocean and is surrounded by dense rainforests and the Guiana Shield. The landscape, with its mountains and forests, can have an impact on the atmospheric pressure in the region. The mountains can act as barriers, causing air to rise, cool, and condense into clouds, leading to higher pressure. The rainforests, on the other hand, release moisture into the air, creating a humid environment that is associated with lower pressure.
