Much of South Africa is currently experiencing a heatwave that is forecasted to persist until Saturday in regions such as North West, Free State, and Northern Cape, according to the South African Weather Services (Saws). Even areas that may not technically meet the criteria for a heatwave are expected to endure extreme heat, prompting the public in those locations to take appropriate precautions. These measures include staying hydrated, avoiding outdoor activities during the hottest parts of the day, dressing appropriately, and ensuring the well-being of vulnerable individuals.
The intensified heatwaves in South Africa align with the global trend of rising average temperatures, as revealed in a recent report by the journal Nature, which documented a 1.7°C increase compared to pre-industrial levels. The year 2023 was noted to be the hottest on record, with parts of the world experiencing exceptionally high temperatures and widespread wildfires. In the Western Cape specifically, around 6,000 wildfires were reported between December 2023 and January 2024, scorching nearly 100,000 hectares of land. The El Niño weather phenomenon and dry, windy conditions have exacerbated these fires.
Dr. Dawn Mahlobo, the senior manager of climate services at Saws, emphasized that while heatwaves during this period were not unusual, the current intensity of temperatures surpasses previous levels. Factors such as El Niño contribute to the warmer-than-normal temperatures, intensifying the heatwave. Mahlobo highlighted that climate change has led to significant alterations in weather patterns, particularly in the eastern regions of South Africa, resulting in higher temperatures and more extreme weather events.
The Department of Health’s National Health Action Guidelines outline the potential health risks associated with extreme heat, including dehydration, heat-related illnesses, and organ damage. Vulnerable populations, such as the elderly, children, and individuals living in inadequate shelter, are at higher risk during heatwaves. Preventive measures recommended include ensuring access to water, shade, and rest for vulnerable groups, as well as implementing strategies to mitigate the impact of extreme heat on health and well-being.
In addition to the heatwave alert, Saws also issued a warning for severe thunderstorms that could lead to flooding, property damage, power surges, and lightning-related injuries. Dr. Nicholas Brink, a research consultant at the Wits RHI Research Institute, emphasized the unequal impact of heatwaves on society, particularly on vulnerable groups who may struggle to cope with the extreme temperatures. Employers are urged to provide adequate hydration and rest breaks for workers, especially in outdoor or high-temperature environments, to improve productivity and reduce health complications.
Overall, the combination of the ongoing heatwave and potential severe weather conditions underscores the importance of taking proactive measures to protect individuals and communities from the adverse effects of extreme heat and related hazards. It is crucial for the public to stay informed, follow safety guidelines, and support those who may be more susceptible to the impacts of heatwaves.
