Guinea-Bissau Barometric Pressure Map
Depending on how many places we monitor in Guinea-Bissau, 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.
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 Guinea-Bissau is shaped by tropical weather systems. The Intertropical Convergence Zone (ITCZ) brings low pressure and rain during the wet season. In the dry season, the Harmattan winds from the Sahara create higher pressure and drier air.
Geography
Guinea-Bissau’s flat coastal land and proximity to the Atlantic Ocean affect air pressure. Ocean breezes help keep pressure more stable along the coast, while inland areas may see quicker pressure changes due to less influence from the sea.
Seasonal Cycles
During the rainy season, which lasts from June to October, air pressure drops as moist air arrives from the ocean. In the dry season, from November to May, higher pressure moves in as dry, continental air replaces the wet winds.
Climate Change
Climate change is making pressure patterns less predictable in Guinea-Bissau. Rising ocean temperatures can affect how the ITCZ moves and increase extreme weather, leading to shifts in both low and high pressure events throughout the year.
