Track the barometric pressure in Oshawa hour by hour and stay informed about how it will change over the next 6 hours.
The barometric pressure in Oshawa is influenced by its location on the north shore of Lake Ontario. It tends to be lower than in surrounding inland areas. This is because the lake's moisture-laden air masses move over the city. As a result, Oshawa's pressure is often lower than in cities farther away from the lake.
Oshawa is situated in the Greater Toronto Area, near the lake's shoreline. To the north and east of the city, there are gentle hills and forests. These features do not block or disrupt the airflow from the lake. As a result, air masses can move freely over the city, affecting the pressure.
The surrounding landscape plays a significant role in shaping Oshawa's weather patterns. The lake's presence helps moderate the city's climate, keeping temperatures relatively mild. This, in turn, influences the barometric pressure, making it more prone to fluctuations.
