Port Dover is near Lake Erie, which affects its air pressure. The lake makes the air pressure rise in winter and fall, and drop in spring and summer.
When winds blow from the lake, they bring mild air, making pressure rise. Winds from the land bring cold air, making pressure drop.
In winter, cold air from the north makes pressure drop, causing cold and snowy weather. In summer, warm air from the lake makes pressure rise, causing warm and humid weather.
Port Dover has a humid continental climate, which means big temperature differences between seasons. This causes pressure to change a lot throughout the year, making the weather changeable.
