Bluffton's barometric pressure is affected by its coastal location. The city experiences a slight drop in pressure during the summer months. This is due to the warming of the ocean water. As the water warms, it expands and rises, causing the air pressure to decrease.
Bluffton is situated near the May River and surrounded by marshlands. The Atlantic Ocean is just a few miles east. The city's low-lying terrain allows moisture-laden air from the ocean to move inland. The surrounding wetlands and waterways influence the weather patterns.
The terrain and waterways cause the air to be more unstable. This can lead to thunderstorms and heavy rainfall during the summer. In the winter, cold fronts from the north bring dry air, causing a slight increase in pressure.
