Costa Rica Barometric Pressure Map

Depending on how many places we monitor in Costa Rica, 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

Weather systems like the Intertropical Convergence Zone (ITCZ) and trade winds influence air pressure in Costa Rica. When the ITCZ moves over the country, it brings low pressure and more rain. Tropical storms and hurricanes can also change air pressure quickly, causing sudden weather changes.

Geography

Costa Rica’s geography shapes how air pressure is distributed. The country has mountains, valleys, and coasts on both the Pacific and Caribbean sides. High mountains can block cool or moist air, creating different pressure on each side. The Caribbean side can get lower pressure and more rain, while the Pacific may stay drier.

Seasonal Cycles

Each year, Costa Rica has clear pressure cycles. During the dry season from December to April, high pressure from the north keeps skies clear and rain away. In the rainy season from May to November, the pressure drops as warm, moist air moves in, creating storms and heavy rains.

Climate Change

Climate change is making air pressure patterns less predictable in Costa Rica. Some places are getting more intense rainfall or longer dry spells. These changes are caused by shifts in pressure systems, which could mean more extreme weather in the future.
