Hourly Pressure Trends
Track the barometric pressure in Mississauga hour by hour and stay informed about how it will change over the next 6 hours.
Mississauga's weather is affected by its location near Lake Ontario, which makes the air pressure change frequently.
Air pressure is lower near the lake because water heats and cools slower than land, making the air above it rise or sink.
In winter, cold Arctic air brings high pressure, making the air sink, and it gets cold and dry.
In summer, warm air from the Gulf of Mexico brings low pressure, making the air rise, and it gets hot and humid.
Mississauga has a continental climate with cold winters and warm summers, which means big air pressure changes between seasons.
