Gauteng residents have been warned to brace for another week of scorching temperatures and extreme heat with the mercury expected to spike significantly.
The regional weather service, Gauteng Weather, has predicted temperatures in the thirties with a slight chance of rain for the province.
High temperature
Johannesburg
Temperatures in Johannesburg range from a low of 15°C to very hot and reach a high of 32°C on Tuesday.
Pretoria
Pretoria is predicted to heat up with hot temperatures.
Temperatures in the city are expected to start with a minimum of 18°C on Monday, and reach a peak of 34°C on Wednesday, with a chance of rain.
Other provinces
The South African Weather Service (SAWS) has also forecast heatwave conditions in other parts of the country.
“A heat wave with persistent temperatures is expected in the Northern Cape, except for the local municipalities of Kamiesberg and Richtersveld, in the Free State except in the north-east until Monday and in the north-east of the Eastern Cape until Wednesday.”
“Extremely hot and uncomfortable conditions are expected in Khai-Ma municipality in the Northern Cape as well as Oudtshoorn and Prince Albert municipalities in the Western Cape,” he said.
Prevention
According to SAWS, when the temperature is too high, the ability to cool the body through sweat is reduced, and this can lead to dehydration and heat stroke.
Affected individuals are advised to stay out of the sun, especially between 12pm and 3pm, avoid strenuous activity or work outside and stay hydrated.
Eliminate the burden
Hot weather can also put pressure on the power grid as people use a variety of appliances, including air conditioners, to keep cool.
Eskom is currently implementing stage 6 load shedding in the country for the past two weeks.
High alert
Meanwhile, Johannesburg Emergency Services Robert Mulaudzi urged residents to be cautious during the extremely hot conditions.
“Residents are advised to stay hydrated, drink plenty of water, avoid direct sunlight especially between 11 a.m. and 3 p.m. People who work in direct sunlight should take regular breaks to prevent heat exhaustion and heat cramps that can lead to heat stroke.
“On our part as the City of Johannesburg Emergency Management Service, we remain alert to respond to emergencies that may arise throughout the City of Johannesburg,” Mulaudzi said.
