Gauteng, South Africa | Residents of Gauteng have been urged to prepare for a heatwave that is expected to affect the province, as well as several other regions in South Africa.
The South African Weather Service (SAWS) has issued a warning for consistently high temperatures throughout the week.
The heatwave, which began on Monday, is anticipated to bring temperatures into the high 30s in some parts of Gauteng. Areas like Johannesburg and Pretoria will experience extreme conditions, with Johannesburg reaching highs of 33°C and Pretoria experiencing even hotter temperatures of up to 36°C. These temperatures are expected to persist until at least Friday, creating potential risks for residents’ health.
In response to the extreme weather, Johannesburg Emergency Services (EMS) has advised the public to take precautions.
EMS spokesperson Robert Mulaudzi stressed the importance of staying hydrated and avoiding exposure to direct sunlight, particularly between 11 a.m. and 3 p.m., when the sun is at its strongest.

He also recommended that those working outdoors take regular breaks, and that vulnerable groups, such as the elderly and those on medication, remain in cooler environments to avoid heat-related illnesses.
The EMS also raised concerns about an increased risk of veld fires during the heatwave, particularly in dry and undeveloped areas.
The combination of extreme heat and dry conditions could lead to fast-spreading fires, and emergency services are on high alert across the city.
Safety Tips for Coping with Heatwaves
SAWS and EMS have shared several guidelines to help residents stay safe during the heatwave:
- Stay out of the sun: Wear protective clothing such as hats, and apply sunscreen when outdoors.
- Stay hydrated: Drink plenty of water or non-alcoholic, non-caffeinated beverages.
- Limit outdoor activities: Stay in shaded areas or cool indoor spaces, and take regular breaks if working outside.
- Protect vulnerable groups: Keep children and pets safe by not leaving them in cars or exposed to the heat.
Swimming Safety During Heatwaves
As many residents may head to swimming pools to cool off, EMS has issued the following swimming safety advice:
- Secure swimming pools: Cover pools with safety nets when not in use.
- Install fences: Pool fences should be high and secure to prevent children from gaining access.
- Use public pools: Pools with lifeguards present provide a safer alternative for swimming.
Health Risks of Extreme Heat
Extreme heat can lead to serious health issues, such as dehydration, heat cramps, heat exhaustion, and heat stroke. The elderly, children, and individuals with chronic health conditions or on certain medications are particularly at risk.
Heat cramps are painful muscle spasms caused by excessive heat, while heat exhaustion is characterized by dizziness, nausea, and weakness.
The most severe heat-related condition, heat stroke, occurs when the body is unable to regulate its temperature, which can be fatal if not treated promptly.
Authorities are urging residents to stay vigilant and take necessary precautions to ensure their safety during this intense heatwave.
