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 summer, warm air from the Gulf of Mexico brings low pressure, making the air rise, and it gets hot and humid.
