Barometric Pressure in Canada

We monitor barometric pressure across 228 cities in Canada, giving you up-to-date insights into local weather patterns.

Whether you're tracking pressure changes for health reasons, planning outdoor activities, or planning a fishing trip, our data is tailored to conditions in Canada, with detailed readings city by city.

Canada Barometric Pressure Map

Depending on how many places we monitor in Canada, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.

Here you can see which cities experienced the biggest and smallest changes in barometric pressure today. This helps highlight areas with the most stable or unstable weather patterns.

Most volatile

Least volatile

How is it calculated?

Our volatility “beta” number is generated by an algorithm that analyzes hourly barometric pressure changes. It looks at how much the pressure fluctuates from hour to hour. A beta of 0 means no change, perfectly stable pressure. The higher the decimal value, the more variation there has been throughout the day or over a longer period.

Weather Systems

Weather systems bring changes in air pressure across Canada. Low-pressure systems often come from the Pacific Ocean, bringing clouds and storms to the west. High-pressure systems move in from the Arctic or from the south, bringing clear skies and calm weather. These systems shift quickly and can cover large areas.

Geography

Geography also shapes how air pressure is spread out in Canada. The Rocky Mountains block some weather systems, so the west side often has different air pressure than the east. The flat Prairies allow systems to travel farther without obstacles. The Arctic’s cold air often holds higher pressure, especially in the north.

Seasonal Cycles

Pressure patterns change with the seasons. In winter, cold Arctic air creates high pressure in the north and center, while lower pressure appears near the coasts. In summer, southern parts heat up, creating low-pressure areas and more storms. Pressure changes help drive Canada’s strong seasonal weather.

Climate Change

Climate change is causing pressure trends to shift. The Arctic warms up, lowering pressure there and changing how air moves across Canada. This can lead to more frequent storms, longer heatwaves, and changes in usual weather systems. Scientists watch these patterns to predict future climate effects.

Places in Canada

You can find your city in the lists below, by using our search, or on the Canada Pressure Map above. We're tracking barometric pressure across multiple locations in Canada to keep you informed.

Each city includes a pressure status showing whether it's currently high, normal or low, along with two volatility values: one for today and one for the full period, usually 14 days. These help you see how much the pressure is changing over time.
