South Africa Barometric Pressure Map
Depending on how many places we monitor in South Africa, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.Weather Systems
Big weather systems, like the South Atlantic High and the South Indian High, control South Africa’s air pressure. These are large areas of high pressure over the oceans that help bring winds and weather into the country. Low pressure systems, especially from the south, can cause storms and colder weather.
Geography
South Africa’s land is made up of high plateaus, mountains, and coastal regions. The high central plateau, called the Highveld, usually has lower air pressure than the coastal areas because it’s higher above sea level. Mountains like the Drakensberg can block and redirect winds, making local pressure patterns change quickly.
Seasonal Cycles
During winter, South Africa has high pressure over the center and lower pressure cuased by cold fronts in the south. This brings dry air inland and rain to the coastal areas. In summer, a low pressure area forms over the land, pulling in moist air from the oceans and causing thunderstorms.
Climate Change
Climate change is shifting pressure patterns. The highs over the oceans are getting stronger and moving. This can lead to longer droughts in some areas, more intense storms in others, and more unpredictable weather overall for South Africa.
