Napa is situated in a valley surrounded by mountains to the west and east. The coastal mountain range is about 30 miles west of Napa. The Sierra Nevada mountain range is about 100 miles east of Napa.

The surrounding mountains affect the atmospheric pressure in Napa. They block or redirect wind patterns and air masses. This results in a more stable atmosphere and consistent pressure.

The valley shape also contributes to the stable pressure. It allows for gentle air flow and prevents drastic changes in air pressure. Additionally, the valley acts as a trap for cold air, which helps regulate temperature and pressure.
