The barometric pressure in London, Canada, can vary throughout the year. In general, it tends to be higher during the colder seasons, such as winter and early spring. This is because colder air is denser, causing the pressure to increase. Conversely, during the warmer seasons, like summer and early fall, the barometric pressure tends to be lower.
The landscape around London, Canada, plays a role in influencing the atmospheric pressure. Surrounded by the Great Lakes and located in a region with rolling hills and forests, the area can experience changes in pressure due to its proximity to these features. For instance, when a high-pressure system moves across the lakes or the hills, it can cause the air pressure to rise, resulting in clear skies and fair weather. Conversely, when a low-pressure system moves in, it can bring unsettled weather with clouds, rain, or snow.
