Hourly Pressure Trends

The barometric pressure in New Orleans is affected by its location near the Gulf of Mexico. This proximity to a large body of water means that the air is often humid and prone to changes in pressure.
The city is situated in a low-lying coastal area, surrounded by water on three sides. This unique geography contributes to the instability of the atmospheric pressure. The Mississippi River runs along the city's edge, adding to the moisture in the air.
The surrounding landscape is flat and low-lying, with few natural barriers to block or disrupt wind patterns. As a result, weather systems can move quickly and freely across the region. This leads to rapid changes in barometric pressure, making it challenging to predict the weather.
