A combination of flooding due to heavy rain on Friday morning, leading to poor visibility, several vehicle accidents and traffic lights that are out of order worsened the peak-hour traffic.
Cape Town Traffic Service spokesperson Richard Coleman urged motorists to "take caution in this weather".
Rainy conditions are expected from Friday until Tuesday – with a break from the rain from Saturday afternoon until Sunday morning – due to a few cold fronts setting in over the Western Cape.
The most intense cold front made landfall early on Friday, with a short spell of intense rain expected.
A truck that jack-knifed on the N1 outbound before Sable Road obstructed three lanes.
The City’s Disaster Risk Management Centre said: "Due to last night’s heavy downpour, the following weather-related matters have been reported: a roof has been damaged by strong winds in Kirstenbosch; and roadways are flooded across the city in areas such as Grassy Park, Parow and Constantia.
