JOHANNESBURG - The mercury will soar to 37°C in Pretoria on Sunday, the hottest day of the first heatwave of the season.
Johannesburg residents can expect temperatures of up to 34°C.
eNCA Meteorologist Annette Venter said heatwave conditions with persistently high temperatures are expected in Gauteng, eastern parts of North West, eastern parts of the Free State, western parts of Mpumalanga and the western Bushveld of Limpopo.
"The conditions will possibly continue until Monday in Gauteng," said Venter.
Venter said it remains mainly dry in the east with Gauteng with the province still awaiting it's first proper rain going into summer.
"Weather models are indicating that the heatwave will be over by next week Tuesday, but it will remain hot with isolated thunderstorms expected over parts of South Africa."
Venter provided a few heatwave tips:
- Avoid direct sunlight
- Use sun protection lotion when you work or play outdoors.
- Protect the eyes from direct sunlight by wearing sunglasses or a hat with a peak.
- Take enough water or other fluids during the day.
- All elective sporting activities or physical exertion should be cancelled in the midst of a heatwave;
- Make sure that animals have clean and sufficient water.
- If you are in a swimming pool or other open water, use a sunblock as water attracts UV rays which causes severe burns that will only be visible later the day.
- Monitor someone with symptoms of heat exhaustion closely to ensure they do not lose consciousness or seizures, which could be fatal.
- Drink water that is at room temperature, rather than ice-cold fluids.
