Lake Oswego is situated near the Willamette River and surrounded by the Willamette Valley. The city's proximity to the river and valley affects the atmospheric pressure. The valley traps and channels air masses, influencing the pressure.

The surrounding hills and mountains also play a role in shaping the local weather. They force air to rise, cool, and condense, resulting in precipitation. This, in turn, affects the barometric pressure.

The unique combination of the river, valley, and hills around Lake Oswego contributes to its dynamic weather patterns. The city's weather is characterized by frequent changes in pressure, leading to varying conditions throughout the year.
