Residents of South Africa can expect hot or very hot weather in several provinces on Friday. A heatwave is forecast to persist in parts of the Eastern Cape, KwaZulu-Natal, and Mpumalanga, along with an extremely high fire danger level across large areas of the country.

The South African Weather Service has warned of prolonged high temperatures in certain areas of the Eastern Cape until Saturday, in northern KwaZulu-Natal until Sunday, and in Mpumalanga (excluding areas along the Escarpment) until Monday.

The forecast for Friday, October 16, also indicates isolated showers and thunderstorms in some parts of Gauteng, Mpumalanga, Limpopo, North West Province, and the Free State, although good and hot weather is expected in most places.

SAWS has warned that extremely high fire danger is expected across most of the Northern Cape, eastern parts of the Western Cape, in some parts of the Eastern Cape, western Free State, northern KwaZulu-Natal, southeastern Mpumalanga, as well as in the northern and western parts of Limpopo.

Gauteng prepares for hot climate and isolated thunderstorms

Variable cloudiness and warm weather with isolated showers and thunderstorms are expected in Gauteng. Temperatures will be higher in the northernmost parts of the province. A high sunburn index is expected, and residents are advised to take precautions against prolonged sun exposure.

The North West Province and the Free State are forecast to be clear and hot, transitioning to variable cloudiness in the afternoon, with isolated showers and thunderstorms possible in their easternmost parts.

Heatwave persists in Mpumalanga and Limpopo

Clear and warm or hot weather is expected in Mpumalanga, transitioning to variable cloudiness over Highveld in the afternoon. Isolated thunderstorms are possible in the southwestern parts of the province. It is expected to be very hot in some Lowveld areas, and the heatwave warning remains in effect until Monday in some parts of the province, except for areas along the Escarpment.

Limpopo is forecast to have clear and warm or very hot weather, with variable cloudiness and isolated afternoon thunderstorms in the southwestern areas. Extremely high fire danger is also expected in the northern and western parts of Limpopo.

Northern Cape faces extreme fire danger

Clear weather is expected in the central parts of the Northern Cape, while the rest of the province will experience variable cloudiness and warm or very hot weather. Some western areas will be cool or warm, and the east will be windy. SAWS has warned of extremely high fire danger across most of the province. Residents are strongly urged to exercise caution, especially in areas where hot, dry, and windy conditions can promote the rapid spread of wildfires.

Western Cape to face scorching temperatures inland

In the Western Cape, fog is expected in some places in the morning on the west, which will give way to variable cloudiness and warm or hot weather. However, in some eastern parts of the province, temperatures are expected to reach very hot or extremely hot levels. Conditions will be cool along the southwest coast and adjacent inland areas. Fresh or strong northwesterly winds are expected along the west and southwest coasts, while a moderate southerly wind is forecast along the south coast. The sunburn index is expected to be very high.

Eastern Cape to face heat and uncomfortable humidity

Morning fog is expected in some parts of the Eastern Cape, especially south of the Escarpment and along the coast, before the weather becomes clear and warm or hot. In some areas in the interior of the western half of the province, temperatures will be very high, while the eastern half, south of the Escarpment, will also experience very hot conditions. The province is under a heatwave warning, with prolonged high temperatures expected in the areas of Chris Hani, O.R. Tambo, and Alfred Nzo municipalities until Saturday. Extremely uncomfortable and humid conditions are expected in some places. Light to moderate northeasterly winds are expected along the western half of the Eastern Cape coast, which will strengthen to fresh or strong southwesterly winds by evening. The eastern half of the province will experience a moderate or fresh northeasterly wind along the coast.

KwaZulu-Natal to face extreme UV exposure

KwaZulu-Natal is forecast to have variable cloudiness and warm or very hot weather with morning fog patches in the northeast. Isolated showers and thunderstorms are possible in the far northwest, while southern parts of the province will be warm in some places. The heatwave warning remains in effect for some parts of northern KwaZulu-Natal until Sunday. Very hot or extremely hot and uncomfortable conditions are also expected in some eastern parts of the province. The sunburn index is expected to reach extreme levels, making sun protection particularly important. Light to moderate northerly or northeasterly winds are expected along the coast, strengthening to fresh during the day.

Residents advised to take precautions

Given the high temperatures expected in several provinces, residents are advised to maintain hydration, limit strenuous outdoor activities during the hottest hours of the day, and take measures against sunburn. Those in areas with an extremely high fire danger warning should avoid activities that could trigger wildfires and remain vigilant about changing conditions.

The weather service issued a Level 2 yellow warning for reduced visibility in parts of Gauteng, Mpumalanga, and Limpopo on Thursday morning. Fog and low clouds are expected to complicate road conditions.

Drivers in parts of Gauteng, Mpumalanga, and Limpopo may encounter difficult driving conditions on Thursday morning due to low clouds and fog reducing visibility, while extremely high fire risks are forecast in some areas of the North Cape and Northwest.

The South African Meteorological Service has issued a Level 2 yellow warning for reduced visibility in affected areas of three northeastern provinces. This warning is in effect from midnight until 9:59 AM on Thursday.

According to the meteorological service, low cloud bases can significantly reduce visibility in isolated and foggy locations. It has been warned that such conditions may complicate travel, increasing the likelihood of traffic accidents and leading to longer journey times.

Fire Risk Threatens North Cape and Northwest

While drivers in the northeast face poor visibility, conditions with an extremely high fire risk are expected in some areas of the northeastern part of the North Cape and the Greater Tugela Municipality in the Northwest. As conditions favor rapid fire spread, residents in affected areas are advised to exercise caution.

Otherwise, the North Cape will be fair and warm or hot, although cooler conditions are expected in the west. In the afternoon, variable cloudiness and windy weather are forecast for the east.

In the Northwest, it will first be cloudy in the east, then the weather will become fair and warm or hot, with developing variable cloudiness in the afternoon.

Fog and Mist in Northeastern Provinces

Gauteng can expect variable cloudiness and warm weather on Thursday, along with a high ultraviolet solar radiation index. In Mpumalanga, cloudiness with possible mist is expected along the escarpment, and fog is forecast over the eastern Highveld in the morning. The rest of the province will have variable cloudiness and warm weather.

Limpopo will also experience cloudy conditions, with the possibility of mist and patches of morning fog along the escarpment before variable cloudiness and warm weather set in elsewhere. Precipitation forecasts indicate a 30% chance of isolated rainfall in some parts of Limpopo and Mpumalanga, while most of the country is expected to remain dry.

Warm Weather in Central South Africa

Free State will first be cloudy in the east, then become fair, windy, and warm. Variable cloudiness is expected to develop in the afternoon.

KwaZulu-Natal will experience patches of morning fog over inland areas, followed by variable cloudiness and warm or hot weather.

Good Weather in Cape Provinces

The Western Cape is forecast to have fair and cool or warm weather, although variable cloudiness is expected along the southeast coast in the evening. The ultraviolet solar radiation index will be very high.

Morning fog is expected in some places over the interior of the western half of the Eastern Cape, after which fair and warm weather will settle in. The eastern half of the Eastern Cape will also experience morning fog in some places along the escarpment, followed by fair and warm weather.
