The weather on Sunday, 10 August 2025, across South Africa will be marked by significant coastal and rainfall hazards, particularly in the south-west and along much of the coastline.
While inland areas will experience largely fine to partly cloudy conditions, the South African Weather Service (SAWS) has issued multiple Yellow Level 2 warnings for disruptive rainfall, damaging waves, and hazardous coastal winds, which may impact both marine activities and vulnerable communities.
Weather warnings issued for Sunday, 10 August 2025
Yellow Level 2 Warning – Disruptive Rainfall
Heavy rainfall is expected over the south-western parts of the Western Cape, including the City of Cape Town, leading to localised flooding in low-lying areas, informal settlements, and along susceptible roads.
Impact meaning: A Level 2 warning signals a medium likelihood of significant localised disruption. Residents should avoid flood-prone routes and ensure property drainage systems are clear.
Yellow Level 2 Warning – Damaging Waves
Hazardous sea conditions are forecast between Lambert’s Bay and Port Edward, bringing the risk of storm surge, small harbour disruptions, and dangerous navigation for vessels.
Impact meaning: This level indicates a medium probability of dangerous marine conditions that could threaten life and property at sea and along the shore.
Yellow Level 2 Warning – Damaging Coastal Winds
Strong winds between Saldanha Bay and Port Edward could place small vessels and personal watercraft at risk of capsizing or taking on water.
Impact meaning: A Level 2 alert warns of moderate to severe coastal hazards, requiring smaller craft to remain in safe harbour and coastal communities to secure loose items.
According to SAWS’ Seasonal Climate Watch, the south-western regions, including the Western Cape coastline, may see above-normal rainfall during mid-winter, followed by drier-than-normal conditions later in the season.
This supports the heightened flood risk from current systems. Warmer-than-average inland temperatures remain likely, while coastal areas may trend slightly cooler in coming months.
