As winter steadily approaches, residents across several regions of South Africa are preparing for an intense bout of cold, wet, and windy weather. The South African Weather Service (SAWS) has issued a severe weather warning as a powerful cold front sweeps across the country on Tuesday, 20 May 2025. Authorities are urging the public to take necessary precautions as temperatures drop drastically, bringing heavy rainfall, strong winds, and even snow in some higher-lying areas.
This sudden plunge in temperature marks the first significant cold front of the winter season. Forecasters expect it to cause widespread disruption, especially in the Western Cape and Eastern Cape, with ripple effects extending into inland provinces.

Cold Front Hits the Western Cape First
The cold front began making landfall early on Tuesday morning. By midday, Cape Town and surrounding areas were already experiencing gusty winds and steady rain. According to the South African Weather Service (SAWS), this system is unusually strong for this time of year. Forecasters expect it to move inland over the next 24 to 48 hours.
In the Western Cape, residents should prepare for rainfall between 20–40mm. Mountainous areas could receive up to 60mm. Coastal regions are on high alert for localised flooding, especially in low-lying areas and informal settlements. The City of Cape Town’s Disaster Risk Management Centre has activated its contingency plans. Emergency services are on standby to respond to incidents quickly.
What to Expect: Rain, Wind, and Snow
The cold front will also bring damaging winds, with speeds of up to 60km/h expected along the coast. Gale-force winds may lead to fallen trees, flying debris, and potential disruptions to road and air travel. The South African Civil Aviation Authority has issued an advisory for flights in and out of Cape Town International Airport, warning of possible delays or cancellations due to poor visibility and strong gusts.
Most notably, snowfall is forecast for high-altitude regions such as the Hottentots Holland Mountains, the Drakensberg, and parts of the Eastern Cape interior. Motorists travelling on mountain passes are advised to avoid non-essential travel, as roads may become slippery or impassable due to snow and ice.
Inland Impact: Gauteng, Free State, and KwaZulu-Natal
While the coastal provinces feel the cold front’s initial impact, inland areas will begin to feel it by Wednesday. Residents of Gauteng including Johannesburg and Pretoria can expect temperatures to drop to single digits. In some areas, daytime highs won’t exceed 12°C. Light rain may accompany the cold, and the combination could disrupt daily routines, especially for school-goers and commuters.
In the Free State and KwaZulu-Natal, SAWS has warned of a sharp drop in temperatures. Strong southwesterly winds and a biting wind chill will add to the discomfort. Vulnerable groups such as the elderly, the homeless, and schoolchildren face increased risk. Humanitarian organisations and municipal shelters are already mobilising to offer warmth and temporary shelter.
Safety Measures and Community Response
Authorities are urging South Africans to take safety seriously during this period of severe weather. Here are several recommended precautions:
- Secure outdoor furniture and structures: With wind speeds expected to be high, anything not bolted down can become hazardous.
- Avoid unnecessary travel: Especially in mountainous or flood-prone areas.
- Keep warm and dry: Dress in layers, ensure homes are insulated, and avoid exposure to cold for extended periods.
- Stay informed: Follow SAWS and local news for real-time updates and weather alerts.
Communities across the country are being encouraged to check on neighbours, particularly the elderly or those who live alone. Several local NGOs have also launched cold weather relief drives, distributing blankets, jackets, and warm meals to those in need.
Long-Term Forecast and Looking Ahead
While this cold front is expected to pass by Thursday, 23 May, its effects will linger. Damaged infrastructure, wet conditions, and possible road closures may continue to impact daily life for days afterward. SAWS has indicated that further cold fronts are likely as winter progresses, and this system may serve as a precursor to a wetter-than-usual season ahead.
In light of the climate trends seen in recent years, meteorologists are closely monitoring ocean temperatures and atmospheric patterns to better predict the severity of upcoming winter systems.
Residents are reminded that preparedness is key. Stocking up on essentials, checking home insulation, and ensuring reliable heating systems can make a significant difference during extreme weather events.
