Last month for rain as Cape Town dam levels fall short of key threshold

The hydrological year ends on 31 October, with Cape Town’s dam levels still below the 80% mark typically needed to avoid water restrictions.

Cape Town’s combined dam levels currently stand at 75.7%, with warmer and drier weather arriving as summer approaches.

The National Department of Water and Sanitation (DWS) has the authority to impose restrictions on users of the Western Cape Water Supply System.

The possibility is currently under consideration as dam levels remain relatively low.

Other factors include water demand from urban and agricultural users, as well as seasonal weather forecasts.

Cape Town dam levels remain below 80% threshold

Despite recent rain forecasts, dam levels barely changed, reaching 75.7% on Thursday, 1 October.

That is 16% lower than at the same time last year, according to the City.

The City also recorded daily water consumption of 895 million litres, above its 860 million litres per day limit.

“Proactive water savings remains of utmost importance as dam levels look unlikely to reach the 80% threshold typically applied to avoid water restrictions,” said Zahid Badroodien, the City’s Mayco Member for Water and Sanitation.

The City estimates household consumption needs to fall by at least 10% during the coming summer and into winter next year.

Driest July on record

Cape Town has witnessed a drier-than-usual winter in 2026, while large parts of the south-western Western Cape experienced their driest July on record as the global effects of El Niño are being felt.

Unlike other major South African cities, Cape Town has a ‘Mediterranean’ climate, with most of the rain falling in winter.

City officials are trying to avoid a repeat of the 2017/18 Cape Town water crisis, and the looming threat of a ‘Day Zero.’

Capetonians urged to save water ahead of summer

The City’s latest 2026 Water Outlook does not indicate an immediate risk to supply. However, it says the potential for restrictions has increased compared with previous years.

The City says its dams need to carry Cape Town through the next winter without relying on unpredictable rainfall.

For context, dam levels fell by about 40% during the past summer because of peak demand.

“Cape Town is a water-scarce city, and using water wisely must remain part of our everyday habits,” Badroodien added.

He added that City teams are replacing ageing pipes, repairing leaks and managing pressure. The City is also investing in groundwater, water reuse and desalination.

Around 70% of high-volume water use takes place at home, according to the City’s consumption statistics.
