Réunion Barometric Pressure Map
Depending on how many places we monitor in Réunion, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.Trends Today
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
Réunion's air pressure changes with passing weather systems. Cyclones during summer bring low pressure, causing storms. High pressure from surrounding ocean areas brings calm, dry weather in winter. These systems move, causing regular shifts in air pressure across the island.
Geography
Réunion’s mountains block and redirect winds. High areas, like Piton des Neiges, create lower pressure on windward sides and higher pressure on sheltered sides. The island’s small size makes pressure change fast, especially near steep mountains or the coast.
Seasonal Cycles
Pressure patterns change with the seasons. In summer, warm ocean water lowers pressure and attracts cyclones. In winter, cool air over the island raises pressure, making dry, stable weather. The switch between these patterns brings strong seasonal cycles in air pressure.
Climate Change
Climate change heats the ocean and air around Réunion. Warm water leads to lower pressure and possibly more storms or cyclones. Pressure differences between ocean and land may also get stronger, making weather less predictable and more extreme.
