The barometric pressure in Forest Grove, Oregon, varies throughout the year. It changes with the seasons, influenced by the Pacific Ocean and the surrounding terrain. Atmospheric pressure fluctuates with the movement of high and low-pressure systems. This results in a mix of sunny and cloudy days.

Forest Grove lies in the Tualatin Valley, west of Portland. The city is surrounded by the Coast Range to the west and the Tualatin Mountains to the east. The valley's shape affects the flow of air, causing the atmospheric pressure to rise and fall. The proximity to the Pacific Ocean also influences the pressure, bringing in marine air masses.

The surrounding hills and mountains force air to rise, cool, and condense, resulting in precipitation. This orographic effect contributes to the region's rainfall. The combination of these factors creates a unique weather pattern in Forest Grove, with a mix of rain and sunshine throughout the year.
