South Africa faces an estimated 1,200 additional heat-related deaths between September and February, as extreme temperatures are expected to rise under intensifying El Niño conditions.
Multiple sources link the projections to a potentially record-breaking Super El Niño, which is associated with hotter weather and shifting rainfall patterns across the region. These changes can increase heat stress, particularly for vulnerable groups, and raise the risk of heat-related illness and mortality.
While outlets focus on different aspects of the same broader outlook—such as temperature impacts versus public health consequences—the overall message is consistent: the seasonal forecast points to heightened heat risk during the coming months. The figure of additional heat deaths is presented as a projection rather than an exact count, reflecting uncertainty inherent in weather forecasting. Authorities and researchers therefore emphasize preparedness and mitigation as temperatures are expected to deviate from typical patterns.
