Forecast

Dunnville, Ontario, Canada has a humid continental climate. This means it has big temperature differences between seasons. In winter, cold air from the Arctic makes air pressure low. In summer, warm air from the Gulf of Mexico makes air pressure high. The Niagara Escarpment, a big hill, blocks some of the air moving from the lake. This helps keep the area's air pressure relatively steady. In spring and fall, air pressure can change quickly, causing unstable weather.
