Barometric pressure

Philadelphia is surrounded by the Appalachian Mountains to the west and the Atlantic Ocean to the east. The mountains block cold air from the west. The ocean brings warm, moist air from the east.

The city's proximity to the ocean moderates its climate. The ocean's warmth keeps the temperature relatively stable. This stability affects the barometric pressure.

The Appalachian Mountains also influence the pressure. They force air to rise, cool, and condense. This creates clouds and precipitation.

The combination of the ocean's warmth and the mountains' force affects the pressure. It leads to a mix of sunny and cloudy days throughout the year.
