Fine, warm to hot weather is expected across much of South Africa on Friday, 30 October 2026, but dangerous conditions will persist in parts of the Eastern Cape and Northern Cape. The South African Weather Service (SAWS) says a heatwave affecting areas of the Eastern Cape is expected to continue until Sunday.
The heatwave advisory applies to parts of the Chris Hani and Alfred Nzo district municipalities. Persistently high temperatures can increase the risk of dehydration, heat exhaustion and other heat-related illness, particularly for people working outdoors, older people and those with existing health conditions.
Residents in the affected areas should limit prolonged exposure to the hottest part of the day, keep drinking water and avoid strenuous activity where possible. Homes should be kept as cool as practical, while children and vulnerable people should not be left in hot, poorly ventilated spaces.
Fire danger remains a major concern
The most serious fire-related warning is in the Northern Cape, where SAWS has forecast extremely high veld fire conditions across most parts of the province. The combination of heat and dry conditions can allow fires to spread quickly, threatening farmland, vegetation and nearby communities.
People working with open flames or machinery that may create sparks should take additional care. Fires should be properly extinguished, and any smoke or fire that appears to be spreading should be reported to the relevant emergency services without delay. The warning is a reminder that hot weather is not only a comfort issue but can also create a direct risk to lives, property and agricultural land.
Regional forecast for Friday
Gauteng will start out fine before cloud increases during the afternoon, with conditions ranging from warm to hot. The expected UVB sunburn index is high, so residents should use protection against prolonged exposure to direct sunlight.
Mpumalanga can expect morning fog in places, followed by afternoon showers and thundershowers along the escarpment and eastern Highveld. Elsewhere, conditions should be fine and cool to warm, with afternoon cloud developing outside the Lowveld. Limpopo will be fine and warm to hot, with cloud building over central areas later in the day.
North West will be fine and hot, becoming partly cloudy during the afternoon. The Free State is also expected to be fine and hot, although isolated afternoon showers and thundershowers are possible in the east.
| Province or area | Expected conditions | Public-safety note |
|---|---|---|
| Northern Cape | Hot to very hot in many areas; mist along the west | Extremely high veld fire danger |
| Western Cape | Hot, with very hot conditions in the Central Karoo | Very high UVB index |
| Eastern Cape | Warm to hot, with coastal fog in places | Heatwave continues in specified districts |
In the Northern Cape, the west will be cloudy and misty in places, while the remainder of the province will be fine and hot to very hot. Afternoon cloud is expected in the east, with warmer conditions in the north-western parts.
The Western Cape will be partly cloudy and hot along the southern areas. Elsewhere, it will be fine and hot, with very hot conditions in the Central Karoo. The province’s UVB sunburn index is expected to be very high, requiring extra care during outdoor activities.
In the western half of the Eastern Cape, morning and evening fog may occur near the coast. Away from those areas, the weather should be fine to partly cloudy and warm to hot. The forecast indicates a mixture of coastal visibility concerns and inland heat, with the broader heatwave advisory remaining in effect in parts of the province.
- Protect yourself from prolonged sun exposure, especially in Gauteng and the Western Cape.
- Drink water regularly and reduce strenuous activity during the hottest periods.
- Take extreme care with fires and equipment that can produce sparks in the Northern Cape.
- Be alert for fog near the Eastern Cape coast and morning fog in parts of Mpumalanga.
Friday’s forecast therefore combines generally settled national conditions with several localised hazards. The main priorities are managing heat in the Eastern Cape, limiting sun exposure in areas with high UV levels and preventing veld fires where conditions are rated extremely dangerous.
