The City of Cape Town has issued a warning to residents ahead of a cold front expected to impact the Western Cape from Friday evening.

The weather system is set to bring strong winds, heavy seas and colder temperatures, with potential risks including falling trees, flying debris and minor structural damage.

The South African Weather Service (SAWS) indicated that the cold front will become more established by early Saturday. While such systems can occur throughout the year, they are more common and often more intense during the winter months, particularly from June to early September. The Western Cape is typically one of the regions most affected during this time.

Although the approaching front is not classified as particularly intense, it is forecast to produce widespread cold and rainy conditions along with strong to gale-force winds.

Areas expected to be most affected include Cape Town, the West Coast District, the western Overberg and the Cape Winelands. Rainfall totals could range between 10 and 20 millimetres in many parts, with mountainous or high-lying areas possibly receiving up to 40 millimetres.

As the system moves eastward, it is expected to weaken. This means the eastern regions of the Western Cape may experience little to no rainfall, although windy conditions will still persist.

The Cape Town Weather Office has issued Yellow Level Warnings for damaging winds and high waves from Friday night. These conditions may cause disruptions, particularly along wind-prone routes and for the maritime sector.

Wind speeds are expected to range between 30 and 50 kilometres per hour across much of the Western Cape and the southern parts of the Northern Cape. Gale-force gusts may occur along the coast, in the Cape Winelands, Central Karoo and southern Namakwa region.

There are no storm surge warnings in place at this stage. However, warnings for high seas remain active, with wave heights between four and six metres expected on Saturday and Sunday. These rough conditions may be further impacted by the start of Spring Tide on Monday, which could lead to higher-than-normal coastal tides.

A separate weather advisory has also been issued for the southern high ground of the Northern Cape and the northwestern parts of the Western Cape. These areas can expect very cold, wet and windy conditions.

Residents are encouraged to take necessary precautions, such as securing outdoor items and limiting travel during peak weather periods. The City and weather authorities will continue to monitor the situation and provide updates as needed.
