Brrrr! Coldest night of 2023 with temperatures to drop below zero

Gauteng will hit the first sub-freezing temperatures for Johannesburg, central Pretoria and Vereeniging due to a strong cold front.


Regional weather forecaster Gauteng Weather urged residents to keep extra warm with Sunday evening’s forecast to be the coldest evening of 2023 so far.

Last week, Gauteng Weather warned that another cold front was expected to hit the province, with temperatures expected to drop below freezing in the three major metros.

According to the latest forecast, residents must take extra precautions against the freezing temperatures.

Freezing temperatures

“Coldest night so far in 2023 expected in Gauteng overnight with first sub-freezing temperatures for central Pretoria and Johannesburg, due to strong cold front,” Gauteng Weather tweeted.

The latest temperature forecast show that mercury in Johannesburg is expected to drop well below zero tonight – to -3°C.

The temperature in Pretoria is expected to drop to -1°C with Vereeniging in the Vaal the coldest of the metros with -6°C.

Gauteng Weather also warned of a very cold start to the week.

Temperatures in Johannesburg are expected to drop to a minimum of -3°C on Monday with a maximum of 16°C on Thursday.

The mercury in Pretoria will drop to -1°C on Monday with a maximum of 18°C on Thursday.

Both Johannesburg and Pretoria will also experience very windy conditions.

Emergency services

The cold front is likely to force residents to use all available heating apparatus to keep warm during the freezing temperatures with Johannesburg Emergency Services (EMS) assuring people that officials will be on high alert for any eventuality.

Joburg EMS spokesperson Robert Mulaudzi said the city‘s residents must ensure that all heating devices are well looked after and not left unattended in order to prevent fire incidents during this cold front.

“From our side as the emergency management services, we remain on high alert monitoring all seven regions of the city to make sure that we are able to respond to all emergencies that might occur throughout the city,” said Mulaudzi.

Power outages

Meanwhile, Johannesburg’s City Power said it was taking necessary precautionary measures to deal with high volumes of power outages across the city.

City Power spokesperson Isaac Mangena said cold temperatures would lead to higher electricity demand, which puts pressure on its network.

“City Power is taking all precautionary measures, including beefing up resources in our SDCs, to mitigate against outages that may be triggered by adverse weather. Our teams are on high alert and we will increase resources in high-pressure areas to minimise the disruption of power supply to our residential customers,” Mangena said.

Load shedding

The freezing conditions are likely to also put pressure on the electricity grid.

However, Eskom has maintained load shedding at a minimum with steady stage 3 and, at times, suspending the deliberate power cuts altogether.

Be that as it may, Eskom said it will publish another update should any significant changes occur.
