Madagascar Barometric Pressure Map

Depending on how many places we monitor in Madagascar, 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 and the Mascarene High help control air pressure in Madagascar. The Intertropical Convergence Zone brings low pressure and rain, while the Mascarene High brings high pressure and dry, windy weather, especially from the southeast.

Geography

Madagascar's mountains block or change winds. The central highlands force moist air up, lowering pressure and causing rain on east slopes. The west gets more dry air, so pressure tends to be higher there. Coastal zones see more changes as ocean winds push in different air masses.

Seasonal Cycles

During summer from November to March, pressure drops because hot air rises—this brings lots of rain and sometimes cyclones. In winter from May to September, cooler, dry air from the southeast increases air pressure, making weather calmer and drier, especially on the east coast.

Climate Change

Climate change may cause more extremes in pressure patterns. Warmer temperatures bring more low pressure and stronger storms, especially cyclones. Scientists think dry and wet seasons might change timing or intensity, affecting how pressure patterns work across the island.

Places in Madagascar

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