Barometric pressure in London, Ontario, Canada is affected by the movement of high and low-pressure systems from the west. These systems bring changes in the weather. The pressure is higher when a high-pressure system is over the city, and lower when a low-pressure system is present.

London is situated in a valley in southwestern Ontario. The valley is surrounded by lakes and hills to the north and west. The landscape affects the flow of air into and out of the valley. When winds blow from the west, they must rise to cross the hills, cool, and condense, resulting in precipitation.

The city's location in the valley also leads to temperature variations. Cold air from the north and west settles in the valley, making it colder than surrounding areas. Warm air from the south and east has to rise to enter the valley, making it warmer than surrounding areas. As a result, London's temperature can be different from nearby cities.
