The barometric pressure in Seattle is affected by its proximity to the Pacific Ocean and the surrounding mountains. This combination leads to frequent changes in pressure. Low-pressure systems from the Pacific dominate the winter weather, bringing cloudy and rainy conditions. High-pressure systems from the north and east bring fair weather during the summer.

Seattle is surrounded by the Olympic Mountains to the west and the Cascade Range to the east. The Puget Sound, a body of water, lies between the city and the Olympic Mountains. This unique landscape channels airflow and influences the barometric pressure. The mountains force air to rise, cool, and condense, resulting in rain.
