Hamilton is situated at the western end of Lake Ontario. The lake's presence affects the city's weather. Moist air from the lake moves inland. This air rises, cools, and condenses, forming clouds and precipitation.

The Niagara Escarpment, a steep slope, runs east-west across the city. This escarpment blocks and redirects air masses. It influences the path of storms and air pressure systems. As a result, Hamilton's weather can be quite changeable.
