Portugal Barometric Pressure Map

Depending on how many places we monitor in Portugal, 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

Portugal’s weather pressure comes mostly from the Azores High and the Iberian Low. The Azores High is a large area of high pressure over the Atlantic Ocean. It often brings dry, sunny weather to Portugal. Low pressure, especially from the Iberian Low, brings clouds and rain, mostly in winter.

Geography

Portugal’s geography affects pressure patterns. The country is close to the ocean, so sea breezes and maritime air change the pressure often. The mountains in northern Portugal block some weather systems. Coastal areas usually have steadier air pressure than inland places.

Seasonal Cycles

Pressure cycles change by season. In summer, the Azores High gets stronger, so Portugal has higher air pressure and more dry, stable weather. In winter, air pressure drops because of more storms and low pressure from the Atlantic, causing rainy, windy weather.

Climate Change

Climate change is making pressure patterns less predictable. The Azores High might get stronger and move north, which could mean longer dry spells for Portugal. Storms and low-pressure systems could become rarer or more intense, making weather swings sharper than before.

Places in Portugal

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