Chile Barometric Pressure Map

Depending on how many places we monitor in Chile, 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

Chile’s weather is influenced by high and low air pressure systems. The South Pacific High, a large area of high pressure over the ocean, often brings dry and stable weather to the central and northern parts of Chile. Low pressure systems from the south bring rain and storms, especially in the south of the country.

Geography

Chile is a long, narrow country with the Andes Mountains to the east and the Pacific Ocean to the west. The mountains block moist air from moving east, which causes lower pressure on the ocean side and higher pressure on the mountain side. The Atacama Desert in the north has high pressure and very dry conditions because of this effect.

Seasonal Cycles

Pressure patterns change through the year. In the summer, the South Pacific High is strong, so most of Chile is dry and sunny, especially in the north and center. In the winter, low pressure systems from the south become stronger and move farther north, bringing more rain and storms to central and southern Chile.

Climate Change

Climate change is affecting Chile’s air pressure patterns. The South Pacific High seems to be getting stronger, pushing rain systems farther south. This makes central Chile drier and can lead to longer droughts. Extreme weather, like floods and heavy rain, can happen more often when low pressure systems become stronger.

Places in Chile

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