Severe Marine Conditions Along the Coast
The Western Cape is under a yellow level 2 warning for damaging waves. The alert affects the coastline between Saldanha Bay and Plettenberg Bay, with rough seas extending to Alexander Bay by Friday.
These severe marine conditions are dangerous for:
- Small boats and fishing vessels, which may capsize.
- Swimmers and surfers due to strong currents.
- Ports and coastal infrastructure which could be damaged by strong waves.
If you’re near the coast, it’s best to stay on land. The coastal weather warning is in effect, and conditions are not safe for any recreational or commercial sea activities.
Fire Danger Warning in the Northern Cape and Free State
Today’s weather alert includes a fire danger warning for the Northern Cape and western Free State. Extremely dry conditions combined with strong Berg winds have created a serious risk of veld fires.
Why this matters:
- Fires can start quickly and spread fast in dry grass and shrubs.
- Strong winds make firefighting more difficult.
- Farming areas and rural settlements are most at risk.
Residents should avoid all open flames, report smoke immediately, and follow local fire safety regulations. This alert is especially important for farmers and communities in high-risk zones.
Cold Weather South Africa: Interior Provinces Brace for Chill
The central interior—including the Free State, Northern Cape, and North West—is experiencing cold weather with strong winds. Temperatures are expected to drop to 2°C, especially overnight and early morning.
Weather impacts:
- Wind chill will make it feel colder than actual temperatures.
- Some areas may see isolated showers.
- Cold and wind could impact livestock and water supply systems.
If you’re in these areas, stay warm, wear multiple layers, and avoid unnecessary exposure to cold and wind. Today’s weather alert places these provinces at moderate weather risk.
Rain, Fog and Wind in the Cape Provinces
In the Western Cape, scattered showers are expected throughout the day. Winds will remain strong along the coast, especially in the south-west. These conditions match SAWS’ earlier weather forecast for South Africa.
In the Eastern Cape, expect early morning fog along the coast and cool, cloudy conditions inland. Isolated rain and thunderstorms may develop later in the day.
Drivers should take care on foggy roads, especially near mountain passes or coastal routes. Visibility will be low, and road surfaces may be slippery.
High UV Index South Africa: Don’t Skip Sun Protection
Even though it’s winter, today’s weather alert includes a warning for high UV index levels in Gauteng, KwaZulu-Natal, and parts of Mpumalanga. Clear skies and dry air can still cause sunburn.
Sun safety tips:
- Use SPF 30+ sunscreen, even if it’s cold.
- Wear long sleeves, sunglasses, and hats.
- Limit sun exposure during midday hours.
This type of UV warning is often overlooked in winter but can cause long-term skin damage if ignored.
