The South African Weather Service (SAWS) has issued an extreme heatwave warning for residents in parts of the Northern Cape (NC) and Western Cape (WC). Both provinces are facing dangerously high temperatures and extreme fire danger conditions expected to persist until Wednesday.
Communities in Kamiesberg, Bergrivier, Richtersveld, and Matzikama are urged to take extra care as temperatures climb steadily, increasing the risk of veld fires, heat exhaustion, and dehydration.
SAWS forecaster Lindelwa Mboyi explained that the current combination of hot, dry weather and strong winds creates perfect conditions for fires to spread rapidly. Residents are encouraged to avoid using open flames, hosting outdoor braais, or engaging in any activities that could trigger fires during this period.

UVB and Health Safety
The UVB sunburn index is extremely high across much of the Western and Northern Cape, creating a serious risk of sunburn and heat-related illness.
To stay safe:
- Stay indoors or in shaded areas during the hottest parts of the day.
- Drink plenty of water.
- Apply sunscreen, wear hats, and light, breathable clothing.
- Avoid intense outdoor activity between 10:00 and 16:00.
Health authorities urge communities to check on children, the elderly, and outdoor workers, who are most at risk of heatstroke and dehydration.
Community Safety and Fire Precautions
Local municipalities have distributed notices urging residents to:
- Avoid open fires, discarded cigarette butts, and unattended flames.
- Keep emergency contact numbers easily accessible in case of fire outbreaks.
- Ensure livestock and pets have access to shade and water.
Farmers are encouraged to postpone burning operations and closely monitor wind direction to prevent runaway fires.
Looking Ahead
According to SAWS, a cooler system moving in from the southwest is expected to bring slight relief by Thursday, especially along coastal areas. However, hot and dry conditions are likely to persist inland across the Namaqualand and Karoo regions.
Meteorologist Jabu Ntuli noted that South Africa is now entering late spring, a time marked by unpredictable weather shifts. While heatwaves are common, residents are advised to stay alert for sudden thunderstorms that can develop quickly in hot conditions.
Stay Safe, Stay Cool
As South Africa continues to face intense heat, residents are reminded that preparedness and caution save lives. Stay updated through official SAWS channels, municipal social pages, and trusted weather platforms. Be alert, stay hydrated, and report any fires immediately to local authorities.
