Barometric Pressure in Ireland

We monitor barometric pressure across 23 cities in Ireland, 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 Ireland, with detailed readings city by city.

Ireland Barometric Pressure Map

Depending on how many places we monitor in Ireland, 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

Atlantic storms called depressions often move over Ireland. These bring low air pressure, making weather windy and wet. In summer, sometimes high pressure from the south brings dry, settled weather. Ireland’s pressure changes quickly when these systems pass over.

Geography

Mountains in the west block some weather systems. This means the west coast often gets lower pressure, wind, and rain, while the east is a bit more sheltered. Ireland’s small size means pressure differences are not huge, but geography matters for local weather.

Seasonal Cycles

During winter, low pressure is more common. This brings frequent storms and rain. In summer, high pressure sometimes moves in, so there are periods with calmer, sunnier weather. The pressure patterns repeat every year, but exact timing changes.

Climate Change

Climate change is causing more extreme weather. Storms can get stronger and happen more often, which means lower air pressure events might increase. High pressure heatwaves may also last longer. These trends can make Ireland’s weather less predictable over time.

Places in Ireland

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