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

Australia Barometric Pressure Map

Depending on how many places we monitor in Australia, 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

Australia’s weather is shaped by high and low-pressure systems. High-pressure systems, called anticyclones, bring clear skies. Low-pressure systems, like troughs and cyclones, cause clouds, rain, and storms. These systems move across the country and change the weather from day to day.

Geography

Geography makes air pressure uneven in Australia. The coastal areas, mountains, and deserts all affect the movement of pressure systems. Mountains can block or slow weather systems. The dry, flat interior often has high pressure, while moist coastal regions get more low-pressure systems.

Seasonal Cycles

Seasonal cycles change air pressure over the year. In summer, the center of Australia often has low pressure, drawing wet, tropical air from the north. In winter, high pressure covers the interior, bringing dry and stable weather. Southern areas get more storms and rain from passing low-pressure systems in winter.

Climate Change

Climate change is altering pressure patterns in Australia. High-pressure systems are becoming more common and lasting longer, especially in the south. This leads to less rainfall and drier conditions in some areas. Climate change may also cause stronger or more frequent extreme weather, like cyclones or droughts.

Places in Australia

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