Forecast
Marietta, Georgia's barometric pressure is influenced by its location in the southeastern United States. The city experiences a humid subtropical climate. Pressure systems from the Gulf of Mexico and the Atlantic Ocean affect the region.
Marietta is situated in the foothills of the Appalachian Mountains. The mountain range to the north has a significant impact on the city's atmospheric pressure. The mountains force air to rise, cool, and condense, resulting in precipitation. This orographic effect contributes to the region's varying pressure patterns.
