Barometric pressure in Petaluma is influenced by the coastal proximity of the city. The pressure often changes with the tides. It tends to be higher during low tide and lower during high tide.
Petaluma is situated near the Pacific Coast and is surrounded by rolling hills. These hills can create a unique microclimate. The surrounding landscape affects the air pressure, as the hills can block or redirect air masses.
