What you need to know now: the South African Weather Service has issued an impact-based Yellow Level 2 warning for damaging winds at sea between Table Bay and Cape Agulhas from the morning, spreading to Plettenberg Bay in the afternoon. Mariners and anyone planning coastal activities along that stretch should expect difficult navigation and take precautions.
Overview and safety advice
Overall, the Weather Service expects mainly fine, cool to warm conditions across many provinces this week, with local variations including coastal cloud, light rain, isolated showers and morning fog in places. The UVB sunburn index is forecast as High for parts of the country, so sun protection remains advisable on exposed, clear days.
Immediate practical steps:
- Avoid non-essential small craft operations between Table Bay and Plettenberg Bay while the warning is in force; secure loose items on vessels and at harbours.
- If travelling coastal roads or promenades, be alert to sudden gusts and possible sand or debris blown by strong winds.
- Use sunscreen, a hat and eyewear on days with a High UVB index; seek shade during peak sun hours.
- Drivers should take care in morning fog areas — reduce speed and use lights appropriately.

Marine and coastal detail
The alert highlights that damaging winds may make navigation at sea difficult between Table Bay and Cape Agulhas from the morning, with the area of concern extending to Plettenberg Bay in the afternoon. Vessel operators, ferries and recreational boaters should monitor marine forecasts and heed local port and harbour advisories.
Although no fire danger warnings were issued in this update and no other advisories were listed, the combination of gusty coastal winds and dry inland conditions can elevate risk in exposed coastal vegetation; communities and landowners should maintain vigilance.
Health and travel
With a High UVB index in some provinces, the Weather Service emphasises sun protection. People with respiratory conditions should be cautious where morning fog is dense, and commuters should allow extra time when visibility is reduced. Road users in affected coastal areas should be prepared for strong crosswinds, especially on exposed bridges and coastal passes.
Continue to follow updates from the South African Weather Service for changes to warnings and local forecasts. For marine operations, consult harbour authorities and official marine bulletins before departing.
Stay weather-aware: check forecasts before travelling, secure items that could be blown away, and protect skin from strong sun even when temperatures feel mild.
