The barometric pressure in Hattiesburg, Mississippi is influenced by its location in the southeastern United States. It is affected by the movement of high and low-pressure systems from the Gulf of Mexico. These systems bring changes in the atmospheric pressure, which in turn affect the weather.
Hattiesburg is situated in a region of gentle slopes and low hills. The city is surrounded by forests and wetlands, which can trap and slow down air masses. This unique landscape feature can cause the atmospheric pressure to fluctuate.

The wetlands and swamps to the west and southwest of the city have a similar effect on the atmospheric pressure.
