The South African Weather Service (SAWS) says a period of cold, wet and windy weather conditions is expected to affect large parts of the country from Friday through to Monday, 20 April.
“This change in weather is associated with the passage of two consecutive cold fronts making landfall over the western parts of South Africa. Initially, these systems are expected to impact the Western Cape and Northern Cape before spreading eastwards across the central and eastern interior over the weekend,” the weather service said.
Daytime maximum temperatures are expected to drop significantly, with some high-lying areas in the western interior and adjacent regions possibly experiencing daytime temperatures between 10°C and 12°C.
These conditions, combined with strong winds, will result in a pronounced wind chill effect. By contrast, the northern extremities of the country are expected to remain relatively warm during this period.
Moreover, marine conditions are expected to deteriorate, with wave heights along the coastline forecast to reach between 4.0 and 5.0 metres from Sunday into Monday, potentially impacting coastal and beach activities.
From Friday, 17 April, cold, wet and windy conditions will dominate the western interior, including parts of the Western Cape and Northern Cape.
By Saturday, 18 April, the cold airmass will penetrate further into the central interior, while the cold front progresses further east of the country.
“Widespread cool to cold conditions are expected across much of South Africa. Isolated to scattered showers and thundershowers are forecast over the central and eastern provinces, including the Free State, North West, Gauteng, Mpumalanga and KwaZulu-Natal.
“By Sunday, 19 April, cold, wet and windy conditions will have spread to the eastern and southern parts of the country, including the southern and eastern coastline of South Africa,” SAWS said.
The impact of these weather conditions are as follows:
- Cold, wet and windy conditions may result in a significant wind chill factor, making temperatures feel colder than measured.
- Localised flooding of low-lying areas and poor drainage systems may occur in regions experiencing persistent rainfall.
- Disruptions to outdoor and beachfront activities are possible due to strong winds and rough seas.
- Reduced visibility and slippery roads may impact travel conditions.
The public is advised to take the following precautionary measures:
- Dress warmly and ensure adequate heating in homes.
- Use heating devices safely to avoid fire hazards.
- Exercise caution when travelling on wet and slippery roads.
- Avoid unnecessary travel during periods of heavy rainfall.
- Secure loose outdoor objects that may be affected by strong winds.
- Stay away from the coastline during rough sea conditions.
- Continuously monitor official weather updates and warnings issued by SAWS.
