Why does Lake Ontario affect the climate in the cities?

Lake Ontario influences the climate in nearby cities primarily through its moderating effects on temperature and precipitation. The lake acts as a heat reservoir, absorbing warmth in the summer and releasing it slowly during the winter, which can lead to milder temperatures in coastal areas. Additionally, it can enhance snowfall and precipitation patterns, particularly in winter, due to lake-effect snow. This interplay between the lake and local weather systems contributes to a unique microclimate in the surrounding urban areas.
