Cape Town - It will be a cold weekend for the Western Cape and Northern Cape, as a cold front hits the provinces on Friday, 11 August, with a flood alert issued by the SA Weather Service. The rest of the country is enjoying warm temperatures with cool weather only hitting the Gauteng area and parts of the Free State.

Cold front

A cold front, expected to hit the Western Cape on Thursday evening, 10 August, is forecast to bring light snow on the Cape's extreme high peaks on Friday.

According to Snow Report SA, snow flurries are estimated, at this stage, to fall along Matroosberg (5cm), Cederberg (1cm), Groot Wellington Sneeukop (5cm) and Sneeuberg in Cederberg (2cm).

"Some of the other high peaks in the Western Cape could also get light dustings," says Snow Report SA, adding that "It is unlikely that there will be any low-level snow at this stage, and all falls will be confined to the high peaks."

Flood warning

The South African Weather Service has issued an alert for Friday as well, due to the possibility of localised flooding in places across the Cape Metropole and southern parts of Cape Winelands.

Added to this gale force wind warnings, issued for Thursday, are expected to continue between Table Bay and Cape Agulhas into Friday morning, with north-westerly winds of up to 60-75km/h expected.

High seas with wave heights of approximately 6 metres have been forecast for Thursday evening, subsiding by Friday afternoon.

Drought conditions continue

While a 30% chance of rain exists over the coastal parts of the Western Cape, water shortages and restrictions remain in place. More rain is expected to hit the Cape on Friday, 11 August. 

Cape Town is currently implementing Level 4b restrictions, and the City of Cape Town says dam storage levels are at 29,4% which means the amount of useable water is at 19,4%. 

Water usage is 642 million litres per day – 142 million litres above our target of 500 million litres of collective water use per day.

"All residents must immediately reduce consumption further and report contraventions to the City. Consumption remains far too high. It is clear that water users are still taking chances with Cape Town’s collective future," says the city.

Temperatures across SA

Minimum temperatures will be cold to very cold across the interior with cool temperatures along the coastal areas of South Africa, before warming later in the day for most of the country except the Western Cape and western parts of the Northern Cape.

On Friday, the coldest place in SA is Sutherland in the Northern Cape, climbing to -6°C.

The cold front hitting Western Cape and Northern Cape will ensure cold maximum temperatures, getting warmer as you move eastward, especially in KwaZulu-Natal and Limpopo. Bethlehem to Ermelo retain cool temperatures.

The hottest city on Friday will be Pietermaritzburg in KwaZulu-Natal, reaching a high of 31°C.
