Trinidad and Tobago Barometric Pressure Map

Depending on how many places we monitor in Trinidad and Tobago, 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

Air pressure in Trinidad and Tobago changes mainly because of weather systems like the Atlantic High and the Intertropical Convergence Zone (ITCZ). The Atlantic High is a large area of high pressure out in the ocean. When it is strong, Trinidad and Tobago get dry winds and clear skies. The ITCZ is a band of low pressure that brings clouds and heavy rain when it moves close to the islands.

Geography

The location and shape of Trinidad and Tobago affect air pressure, too. Trinidad is closer to South America, so it feels more of the low-pressure air coming from the continent. Tobago is smaller and has more breeze from the ocean, which helps even out the pressure changes. Mountains and forests on the islands also cause small, local changes in air pressure.

Seasonal Cycles

During the year, pressure changes with the seasons. From December to May, the dry season, the Atlantic High is stronger and keeps the pressure higher and more stable. From June to November, the rainy season, the ITCZ shifts north and brings lower pressure and more storms. Tropical waves and storms can make pressure drop suddenly.

Climate Change

Climate change is making these air pressure trends less predictable. Warmer seas may make the Atlantic High weaker or stronger at different times, causing more wild swings in pressure. This can lead to more sudden storms or longer dry spells on the islands, forcing people to adjust to new weather patterns.
