The South-African Weather Services (SAWS) warned that the cold front moving in on Friday will result in very rough seas and gale-force winds for the Cape Provinces.


According to Hannelee Doubell, SAWS spokesperson the cold front will make landfall over the south-western Cape on Friday afternoon, 25 June 2021.

“This will result in strong to gale force winds and very rough sea conditions, especially along the coastal areas of the Western Cape, spreading along the Eastern Cape south coast on Saturday morning, 26 June 2021.”

Doubell said the cold front will cause scattered showers and rain, especially over the western parts of the Western Cape.

“The showers and rain will spread along the south coast in the evening.

“Whilst rainfall is not expected to be a significant factor with this system, sustained strong to gale force north-westerly to westerly winds of 55-70 km/h will impact the south-west coast from the morning, spreading along the south coast of the Western Cape in the evening.”


Doubell said these winds will further be accompanied by very rough sea conditions (5.0 to 6.0m wave heights).

“These conditions, coupled with a full moon, are likely to result in dangerous conditions for vessels at sea. This may result in the risk of medium or large vessels dragging anchors or breaking mooring lines.”

She added that localised disruptions to beachfront activities and damage to coastal infrastructure may also occur.

Strong winds (40-60 km/h) will also be present over the western interior of the country, especially over the Western and Northern Cape, and could result in localised infrastructure damage as well as a high risk for the development and spread of veld fires.


The South African Weather Service has issued the following Warnings:

  1. Yellow level 2 warning for wind leading to possible localised infrastructure damage is expected over the Central Karoo, City of Cape Town, Overberg and eastern parts of Cape Winelands of the Western Cape and the southern parts of Namakwa (Northern Cape) on Friday.
  2. Yellow level 2 warning for waves leading to possible coastal infrastructure damage and difficulty in navigation at sea is expected between Lambert’s Bay and Cape Agulhas from Friday afternoon, spreading to Plettenberg Bay in the evening.

    The South African Weather Service will continue to monitor any further developments relating to this weather system and will issue subsequent updates as required.
