The barometric pressure in Wallingford, Connecticut, varies throughout the day and year. It changes depending on weather systems and fronts. Pressure drops when low-pressure systems approach. It rises when high-pressure systems dominate.
Wallingford is situated in the Quinnipiac River Valley. The surrounding hills and mountains influence the local weather. The valley directs air masses from the northwest. Cold air from Canada moves southward through the valley. The hills to the west block warm air from the Atlantic Ocean. As a result, the city's pressure is affected by these geographic features.
The surrounding terrain also affects the flow of air. Moist air from the Long Island Sound is blocked by the hills to the south. This blocks warm, humid air from reaching the city. The combination of these geographic features contributes to the varying barometric pressure in Wallingford.
