The barometric pressure in Bellevue, Washington is influenced by its proximity to the Pacific Ocean and the surrounding mountains. This combination of factors creates a unique pressure system. The pressure is affected by the clash of moist air from the ocean and the dry air from the mountains.

Bellevue is situated in the Puget Sound region, surrounded by the Olympic and Cascade Mountains. The Olympic Mountains block the flow of moist air from the Pacific Ocean. This blockage causes the air to rise, cool, and condense, resulting in rainfall. The Cascade Mountains, east of Bellevue, create a rain shadow effect, drying the air that passes over them.

The landscape around Bellevue also creates microclimates within the city. The hills and valleys channel the wind, directing it through certain areas. This can cause localized variations in pressure and temperature. The surrounding bodies of water, including Lake Washington and Puget Sound, also play a role in regulating the pressure.
