The South African Weather Service (SAWS) has issued a double cold front warning for the Western Cape this week. It forecasts two cold fronts that will make landfall in the province between and . As such, the service has issued weather advisories for gale-force winds and substantial rainfall. Similarly, the province will experience a marked decrease in temperatures, rough seas and the chance of snow in high-lying areas.

Following several days of unseasonably warm pre-frontal weather in the Western Cape, the first of two cold fronts is expected to touchdown today (). North-westerly winds will grow from moderate to strong throughout the day. And these will intensify into gale force winds (75 km/h) in the early hours of , as the second cold front approaches.

In turn, this intense system will bring about heavy rain (forecast at more than 30 mm in parts) and rough sea conditions. Therefore, SAWS warns coastal and maritime operators of possible abnormal waves in the 7-metre range on . Buildings and power lines could be affected by high winds, too.

Moreover, the cold front warning means motorists could see significant delays. Commuters are warned that strong winds will create hazards for high-sided vehicles on national routes.

Furthermore, the cold front warning means persistent rainfall throughout . Rainfall accumulations of 30 mm are expected in central Cape Town and surroundings. Temperatures will drop significantly, with a maximum of only 14°C expected across the Cape Peninsula and adjacent areas. The cold front will move east and inland throughout the day, affecting the Boland and Overberg regions. All of which have experienced substantial flooding as a result of similar weather systems in 2024.

Rainfall intensity will decrease through , with Cape Town expecting intermittent rainfall of 5 mm. Temperatures will remain cool with a maximum of 15°C.
