Track the barometric pressure in Whitby hour by hour and stay informed about how it will change over the next 6 hours.
Whitby's proximity to Lake Ontario causes lake-effect weather, which changes air pressure. The lake warms or cools the air, making pressure rise or fall.
Whitby's low elevation near the lake means air pressure is often lower than in nearby areas. This leads to more unstable air, causing changing weather.
In winter, cold air from the north brings low pressure, making Whitby cold and snowy. Spring brings rising pressure as warmer air arrives, making it milder.
Summer has high pressure, making Whitby warm and sunny. Autumn's declining pressure brings cooler, rainier weather. Whitby has a humid continental climate, meaning big temperature and pressure changes between seasons.
