San Francisco's barometric pressure is typically between 30.0 and 30.3 inches. This is slightly higher than the national average. The pressure remains relatively steady throughout the year.
San Francisco is surrounded by water on three sides. The Pacific Ocean lies to the west. The San Francisco Bay is to the east. The Golden Gate Strait connects the two.
This unique landscape affects the city's atmospheric pressure. The ocean's influence keeps the pressure stable. The bay and strait create a corridor for winds to pass through. This reduces extreme pressure changes.
The surrounding hills and mountains also impact the pressure. They block or redirect winds, moderating the city's weather. As a result, San Francisco's barometric pressure remains relatively consistent.
