A deep cold front sweeping the country over the long weekend is expected to bring significant snowfall to the Eastern Cape’s mountain and high-lying areas, while independent forecasters say light to locally heavy snow cannot be ruled out in parts of Gauteng — including Johannesburg — on Monday, 10 August.
Where snow is likely
Independent forecaster Juandre Vorster — known as The Weather Hooligan — said recent model runs put Johannesburg “back on the radar” for possible snowfall on Monday. Vorster cautioned that the forecast remains sensitive to small changes in the system.
“Some of the latest forecast guidance is once again indicating the potential for significant snowfall across parts of Johannesburg and Gauteng, with some model projections currently suggesting up to around 30cm in the most favourable areas,” said Vorster.
Vox Weather forecaster Annette Botha said the cold front will move across the southern parts of the country on Sunday, with snow expected mainly in mountainous regions. She said heavier snowfall is likely over the mountains and high-lying areas of the Eastern Cape, where some locations could receive around 10cm.
- Eastern Cape highlands: Heavier snowfall likely; some localised amounts around 10cm possible.
- Drakensberg and Lesotho border areas: Snow spreading into the southern Drakensberg and surrounding high-lying areas.
- Gauteng (including parts of Johannesburg): Light snowfall possible in south-eastern suburbs and adjacent towns; isolated model runs indicate heavier accumulations in the most favourable scenarios.
- Western Cape mountains: Light snowfall expected around Sutherland and the Nuweveld Mountains.
Forecast uncertainty and what to expect
Forecasters emphasise that global weather models are still updating and that the precise position, strength and moisture available in the system will determine where the heaviest snow develops. Botha said the ECMWF and GFS global models currently predict significant snowfall on Monday for the eastern Free State, the Free State–KwaZulu‑Natal border, and the Mpumalanga Highveld, in addition to the Eastern Cape highlands.
Vorster warned that “the next few forecast runs will be absolutely critical” and reiterated that forecast guidance can change when systems are complex. Residents and motorists in high-lying areas should therefore monitor updates closely and prepare for rapidly changing conditions.
Practical implications for the Eastern Cape
Snow in the Eastern Cape’s mountain areas can disrupt road travel, agricultural activity and local service delivery. Highways and secondary routes that cross mountain passes — commonly used by freight and commuter traffic — may become hazardous if accumulations occur and temperatures remain low.
Local municipalities and emergency services are usually the first point of contact for road closures and safety advisories. Travellers planning to cross mountain passes over the weekend and into Monday should check for updates from the South African Weather Service (SAWS) and local traffic authorities before setting off.
| Area | Expected snowfall |
|---|---|
| Eastern Cape highlands | Heavier snow; some locations ~10cm |
| Johannesburg / Gauteng (selected areas) | Light snow possible; some model runs indicate up to ~30cm in the most favourable scenarios |
| Western Cape mountains (Sutherland, Nuweveld) | Light snowfall |
Advice for residents and road users
- Monitor official forecasts from SAWS and local traffic authorities; model guidance is changing and updates are expected.
- If travelling through mountain passes, ensure your vehicle is winter-ready: good tyres, warm clothing, a charged phone and extra food and water.
- Expect possible delays on major routes; consider postponing non-essential travel on Monday if your journey takes you through high-lying areas.
- Municipal services in rural and elevated areas should be prepared to assist with road incidents and local disruptions.
Residents in the Eastern Cape’s elevated districts are advised to keep a close eye on the weather over the weekend and to follow updates from SAWS and independent forecasters. The situation remains fluid, and small shifts in the system’s track will determine whether pockets of heavy snow materialise or whether the event remains limited to higher terrain.
The next series of model runs, expected through Sunday, will provide clearer guidance on snowfall distribution and likely impacts for Monday, 10 August.
