Nationwide Fire Danger Remains High

SAWS warns of extremely high fire danger conditions expected across several provinces including Gauteng, Mpumalanga, Eastern Cape, Free State, North West, parts of the Northern Cape, Limpopo, and KwaZulu-Natal. These areas face a heightened risk of runaway fires sparked by dry, hot, and windy conditions. Residents in these regions should avoid open flames, report fires promptly, and follow local fire authority advice. The Western Cape does not currently face elevated fire risks.

Residents can expect fine, warm to hot weather with a very high UVB sunburn index. It is strongly advised to take sun protection measures, such as wearing hats and sunscreen.

Mpumalanga:

Morning fog may linger in eastern areas, but the day will be largely fine and warm, becoming hot in parts of the Lowveld.

Limpopo:

Morning fog patches are expected over the Lowveld and central parts, turning into warm to very hot conditions later in the day.

North West:

Partly cloudy, windy, and warm weather will prevail, with isolated showers and thunderstorms possible in the far west.

Additional Weather Hazards

• Wind: Strong coastal winds are likely along the Western Cape’s west coast and parts of KwaZulu-Natal, potentially impacting marine activities and vulnerable structures.
• Fog: Patches of morning fog may reduce visibility along coastal and some inland escarpment areas, drivers are advised to exercise caution.
• Isolated Thunderstorms: Possible in North West province’s extreme west, bringing short-lived heavy rain that may cause localized flooding.

Health and Safety Recommendations

Given the hot and dry conditions, especially in interior provinces, heat-related illnesses such as heat stroke are possible. SAWS recommends staying hydrated, avoiding strenuous outdoor activities during peak heat hours, and protecting skin from intense sun exposure. Residents in fire-prone areas should follow fire safety rules diligently.

Stay Safe

On 3 September 2025, South Africans face a complex weather mix: from isolated coastal showers and morning fog to hot, dry, and windy conditions inland with serious fire risks. Awareness and preparedness are essential to navigate these conditions safely. Stay updated by following SAWS alerts and heed local authorities’ advice to protect health and property during this period.
