Damaging Coastal Waves and Strong Winds Along the Coast
A yellow level 2 warning is in effect for damaging waves along the coastline stretching from Saldanha Bay in the Western Cape to East London in the Eastern Cape. These waves are expected to cause difficulties for small vessels, including risks of taking on water and capsizing. Beachfront activities may also face localised disruption due to rough seas.
Additionally, a yellow level 1 warning has been issued for damaging winds between Plettenberg Bay and East London, as well as over the Kouga and Nelson Mandela Bay municipalities in the Eastern Cape. These strong winds may cause localised damage to formal and informal settlements and complicate navigation at sea.
Residents along these coastal areas should exercise caution, especially small boat operators and those engaging in water-based activities. It is advisable to avoid unnecessary travel near the coast during periods of peak wave activity.
Intensifying Cold Conditions in the Interior
Very cold conditions are forecast for the interior regions of the Western Cape and the Namakwa District of the Northern Cape. Daytime maximum temperatures will remain at or below 10°C until Friday, 20 June. This cold snap is part of a cold front moving over the south-western Cape, bringing isolated to scattered light showers.
The cold weather may increase the risk of hypothermia and other cold-related health issues, particularly for vulnerable groups such as the elderly and homeless. Residents are advised to dress warmly and ensure adequate heating indoors.

Rain and Snow Risks
While the primary focus is on cold and windy conditions, some light showers are expected in parts of the Western Cape due to the cold front. There is no current severe snow warning; however, previous warnings for disruptive snow and rain earlier in June have heightened awareness of winter weather risks in the region.
Drivers should remain vigilant on wet and potentially slippery roads, especially in mountainous areas where temperatures can drop further.
Fire Danger Status
Currently, there are no extreme fire danger warnings issued for the Western or Northern Cape. However, the Northern Cape and parts of the Free State and North West provinces continue to experience extreme fire danger conditions. Residents in those areas should remain alert and follow fire safety protocols.
