Weather patterns in Plymouth cause changes in barometric pressure as air masses move in and out of the region. Pressure drops when a low-pressure system approaches and rises when a high-pressure system arrives.
Plymouth's 440-foot elevation and surrounding mountains influence atmospheric pressure. Mountains block or redirect air flows, affecting pressure and creating local weather patterns. Valleys and hills can trap or channel air, too.
In winter, pressure is usually lower due to frequent storms and low-pressure systems. In summer, pressure is higher due to dominant high-pressure systems. Spring and fall see more variable pressure trends.
Plymouth has a humid continental climate with significant pressure fluctuations. This leads to varying weather conditions and frequent changes, making it important to check local forecasts regularly.
