Mosterd’s Bay in Cape Town to close for a month due to seawall construction

Mosterd’s Bay in Strand will be off limits this summer as the City of Cape Town pushes ahead with the next phase of its seawall upgrade.

The popular stretch will close from December 15, 2025 to January 15, 2026. The City says it’s a straightforward precaution — safety first, as heavy construction continues.

The closure affects the area between the Strand swimming pool and Norman Road.

Visitors won’t be stranded, though. The nearest safe swimming spot is near the Strand Surf Lifesaving Club, between the red and yellow flags when lifeguards are on duty. Those looking to fish or walk their dogs can head east of Norman Road, close to Greenways.

Deputy Mayor and Mayco member for Spatial Planning and Environment, Alderman Eddie Andrews, urged beachgoers to cooperate.

“Neighbourhood watches and security will be on site to guide visitors to the nearest available beach to the east of Norman Road or west of Strand Pavilion throughout the upcoming holiday period. We ask locals and visitors to please adhere to this closure as this is for your own safety and security. I also want to thank the public for their ongoing support and understanding as we are working on this seawall that is intended to protect this pristine beach for generations to come,” he said.

Sub council 8 chair and ward councillor Chantal Cerfontein reminded residents to keep water safety top of mind.

“The City would like to remind the public of four golden rules when in and around water. Only swim where and when lifeguards are on duty, between their red and yellow flags designating the safest bathing areas; beware of rip currents; please don’t swim under the influence of alcohol and always actively monitor children in and around the water,” she said.

The City also urged beach users to keep an eye on public advisory signage, which may go up during the holiday period.
