Durban — The South African Weather Service (SAWS) has forecast generally fine and warm conditions across most of the country on 31 August and 1 September 2026, but warned residents in parts of KwaZulu‑Natal to expect isolated showers while the Western and Northern Cape face a more severe system.
What SAWS is predicting
According to the national weather service, central and eastern areas of South Africa should see partly cloudy skies with only pockets of rainfall. However, an intense cut‑off low is expected to affect the Western and Northern Cape from Thursday into Friday, bringing cold, wet and windy conditions.

SAWS has issued a series of impact‑based warnings for Thursday and Friday. Of particular note to coastal provinces:
- KwaZulu‑Natal: isolated showers and possible thundershowers in places — residents should expect brief, locally heavy downpours but no large‑scale flooding warnings were issued for the province at the time of the advisory.
- Western Cape: very cold conditions in the southern parts, with Yellow Level 4 warnings for disruptive rainfall and damaging winds across several districts, including the Overberg and Garden Route.
- Northern Cape: Yellow Level 4 warnings for damaging wind in the Namakwa district and for rough seas between Alexander Bay and Plettenberg Bay.
Understanding the SAWS warning levels
SAWS uses a colour and number system to indicate likely impacts. In this system, yellow denotes a moderate risk requiring caution and awareness; orange signals a higher‑risk event demanding increased attention. The number accompanying the colour indicates the likelihood of an impact: levels 4 and 8 are low likelihood, 5 is medium, and 2 and 6 are high.
| Province / Area | Warning | Main impacts |
|---|---|---|
| Western Cape (Overberg, Garden Route, Winelands) | Yellow Level 4 | Disruptive rainfall, flooding of roads and settlements, transport disruption |
| Northern Cape (Namakwa) | Yellow Level 4 | Damaging wind, danger from flying debris, travel affected |
| Coastal strip Alexander Bay–Plettenberg Bay | Yellow Level 4 | Damaging waves, disruption to ports and navigation |
| KwaZulu‑Natal (selected areas) | No specific level issued | Isolated showers and possible thundershowers |
Local impact and practical advice for KwaZulu‑Natal residents
For Durban and other KZN coastal communities, the forecast points to mainly dry, warm weather with the chance of brief, isolated showers. While widespread disruption is not expected in the province, SAWS advises people to take ordinary precautions when rain and lightning occur.
- Drivers should reduce speed on wet roads and be alert to sudden pooling and spray that reduce visibility.
- Outdoor events may continue but planners should have contingency for short heavy bursts and lightning.
- Small stock farmers should monitor pasture and shelter animals if winds pick up locally; SAWS highlighted rural stakeholders in its advisory for the Cape, and similar vigilance is sensible elsewhere.
Mariners and port operators along the west and south coasts should take particular care. SAWS warned of damaging winds and waves that could affect harbours and navigation between Alexander Bay and Plettenberg Bay.
Why the Western and Northern Cape are worst affected
A cut‑off low is a closed pocket of low pressure that becomes separated from the main westerly flow. These systems often bring prolonged rain, strong winds and a marked drop in temperatures. SAWS said the cut‑off low will bring very cold, wet and windy weather to the Western and Northern Cape from Thursday into Friday.
Residents in affected districts should follow local municipal notices and updates from emergency services if conditions deteriorate.
SAWS continues to monitor the situation and will issue further updates if warnings are upgraded or expanded. For the latest forecasts and warnings, members of the public should consult the SAWS website and official social media channels.
