The barometric pressure in Opelousas varies throughout the year. Changes in pressure are driven by weather fronts and storms that move into the region. Pressure drops when low-pressure systems approach. Rises occur when high-pressure systems settle in.
Opelousas sits in a flat, low-lying region. This terrain allows air masses to move freely. The city is surrounded by wetlands and swamps to the south and east. These water bodies heat up slowly, influencing local atmospheric conditions. The nearby Atchafalaya Basin also affects the flow of air.
The location of Opelousas exposes it to humid air from the Gulf of Mexico. Moist air moves northward and collides with cooler air from the north. This clash of air masses creates unstable conditions, leading to changes in pressure. The result is a dynamic weather pattern with frequent fluctuations in barometric pressure.
