Forecast

Johannesburg South has high air pressure most of the year because it's on a high plateau, about 1,753 meters above sea level. High altitude causes lower air pressure normally, but Johannesburg's pressure is still high due to its location. Its geography, with hills and valleys, can cause small changes in air pressure. In winter, cold fronts bring low-pressure systems, causing cooler temperatures and rain. In summer, strong high-pressure systems dominate, leading to warm, sunny days. Johannesburg South has a subtropical highland climate, with significant changes in air pressure throughout the year. The city's climate type results in large daily temperature ranges and varying air pressure. Low-pressure systems bring most of the area's rainfall. Winds can change air pressure, with strong winds in summer and gentler winds in winter. The city's air pressure affects its weather, making it generally mild and sunny. Seasonal changes impact air pressure, with lower pressure in summer and higher in winter.
