El Salvador Barometric Pressure Map

Depending on how many places we monitor in El Salvador, 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

The weather in El Salvador is affected by two main pressure systems. The Pacific high-pressure system brings dry and stable air, while the Intertropical Convergence Zone (ITCZ) brings clouds and rain. These systems shift during the year and change El Salvador’s weather patterns.

Geography

Mountains and valleys in El Salvador change how air pressure moves. The mountains block winds from the Pacific Ocean and funnel air into valleys, sometimes causing quick pressure changes and stronger local storms. Coastal areas often have more stable pressure compared to inland areas.

Seasonal Cycles

Air pressure in El Salvador changes with the seasons. From November to April, pressure is higher and weather is dry because of winds from the north. Between May and October, pressure drops as warmer, moist air arrives from the south, bringing rain.

Climate Change

Climate change can make air pressure patterns less stable. As temperatures rise, pressure changes become less predictable. This can lead to stronger storms, longer dry periods, and sudden shifts in weather, making it harder to predict and prepare for extreme events.
