The barometric pressure in Bethesda fluctuates throughout the year. It is affected by the city's proximity to the Atlantic Ocean and the Appalachian Mountains. Changes in pressure bring different weather patterns. High pressure usually indicates fair weather, while low pressure signals stormy conditions.

Bethesda is situated in a valley near the Fall Line. This transition zone between the coastal plain and the Piedmont plateau creates a unique landscape. The surrounding hills and valleys influence the flow of air masses and the movement of weather systems.

The city's location east of the Appalachian Mountains also plays a role in shaping its weather. Moist air from the Atlantic Ocean rises over the mountains, cools, and condenses, resulting in precipitation. This orographic effect contributes to the region's humid subtropical climate.
