Cape Town beaches: where it is safe to swim

In the summer of 2025/26 the City of Cape Town put 680 lifeguards on 29 beaches, tidal pools and stretches of coast, daily from 10 am to 6 pm, and asked visitors one thing: swim between their red and yellow flags (People's Post, November 2025). Three weeks into the holidays, seven people had drowned across South Africa, nearly all of them at places where no lifeguard was on duty (Cape Argus, December 2025).

That is the first thing to know about Cape Town beaches: a beautiful beach and a safe swim are not the same list. Some of the most photographed bays on the Atlantic side are guarded and cold, a few are not meant for swimming at all, and the warm water of False Bay comes with its own system of spotters, sirens and flags. Sanwin Beachwear ambassadors Nicolas Rimensberger and Floris Baas spent time on the Atlantic side in 2018; their photos run through this guide.

Which Cape Town beaches are safest for swimming?

Muizenberg, St James and Fish Hoek, on False Bay. Together with Caves at Kogel Bay, further east, they are the only beaches with Shark Spotters on duty all year, they have lifeguards in summer, and the water there is about 19 °C in January, against roughly 15.5 °C on the Atlantic side.

Fish Hoek goes one step further. From October to May, when wind and swell allow, an exclusion net is put out in front of the beach every morning and taken in every night. It is designed not to catch or kill animals (Shark Spotters, safety FAQ), and Fish Hoek is the only beach in the city that has one. Beyond the three big beaches, the calmest swims on this side are in the tidal pools of St James, Dalebrook and Kalk Bay, and between the granite boulders at Boulders and Seaforth, which the City's coastal map for 2026 lists as safe swims in calm, shallow water.

Note the last row. Llandudno has a Blue Flag for 2025/26 (WESSA, October 2025), and the same City map still calls it not a recommended swimming spot. A Blue Flag is awarded for water quality, environmental management and facilities. It does not tell you how strong the surf is today.

Are there sharks at Cape Town beaches?

Yes. White sharks come close to the shore in False Bay, with more sightings in summer than in winter, which is why the spotters stand above those beaches and not above Camps Bay.

Muizenberg is the beach with the most sightings: on average 83 white sharks a year, and more than 70 percent of them behind the breakers, according to Shark Spotters. A mountain spotter sits high above the beach with polarised sunglasses and binoculars and sets off the siren when a white shark comes in; a beach spotter changes the flag. The system only works while they are there, so the hours matter as much as the beach.

Put the two systems on top of each other and you get the safest window of the day on False Bay: between 10 am and 6 pm, when spotters and lifeguards are both on duty. Before 8 am and after 6 pm, Muizenberg is a beautiful empty beach with nobody watching the water.

What do the shark flags mean in Cape Town?

Green means good visibility, black means poor visibility, red means a shark was seen recently, and white with a black shark means a shark is in the area now: the siren sounds and you leave the water at once.

When the shark has left the area, the white flag comes down and the red one goes up. You may swim again under red, but Shark Spotters suggest waiting an hour or so until the green or black flag is back, because the shark may return. The red and yellow flags are a different system altogether: they belong to the lifeguards, not to the spotters, and they mark the stretch of water the lifeguards are watching. On a good day at Muizenberg you see both at once.

Which Cape Town beaches are not safe for swimming?

Llandudno, Noordhoek, Scarborough, Danger Beach and Diaz Beach. All five are on the City's own list of places to look at rather than swim, mostly because of rip currents and heavy surf.

Noordhoek Long Beach, below Chapman's Peak, is the one people underestimate. It is a long, wild beach in Table Mountain National Park with strong rip currents, and in April 2026 the lagoon at its northern end broke through to the sea, leaving a wide, deep channel of fast water where someone nearly drowned (Time Out Cape Town, April 2026). Walk to the wreck of the Kakapo, which ran aground in 1900, and swim in False Bay instead.

Inside Cape Point, Diaz Beach is not safe for swimming either. Buffels Bay and the tidal pool at Bordjiesdrif, a few minutes further on, are the safe places there. Take your food with you when you get out of the car: baboons around Seaforth, Millers Point and Bordjiesrif know exactly where a picnic is kept.

Can you swim at Clifton and Camps Bay?

Yes, but briefly. Clifton and Camps Bay are guarded and well sheltered from the summer wind, and the water averaged 15.5 °C in January over the last ten years. In January 2026 it was 12.9 °C at Camps Bay.

The cold comes with the wind. When the south-easter blows, it pushes the surface water away from the Atlantic coast and cold water wells up from below, the City map explains. The same wind hits False Bay head-on, which is why the warm side is best in the morning, before it picks up. On the Atlantic side the mountains break it: Clifton's four beaches are the most sheltered in the city on a windy day, and at the south end of Camps Bay a tidal pool gives you a warmer, calmer swim.

15 °C: a short swim, a long time on the rock

On the Atlantic side you swim a few strokes and then lie on a boulder in the sun. That is what the Sanwin Venice Tequila is for, light blue with a print of shot glasses: the quick-dry peach-skin polyester means you are not lying wet on the granite for long after a dip in 15 °C water. The shorts run small, so if in doubt, take the larger size.

Discover the Venice Tequila

Clifton is reached by steps between the houses, which is how Floris Baas walked down in February 2018. Below, the four beaches lie between granite boulders under Lion's Head, First and Second quieter, Third and Fourth busier. Further south, past the rocks of Bakoven, Llandudno is beautiful and best kept for the sand.

Floris wears the Sanwin Venice Crabs: the same Venice model as the Tequila, classic fit, in navy. Pack the two together, one light and one dark, and you wear one while the other dries on the rock. Travelling with your son? The Venice Crabs also comes in a boys' version, and the matching sets are with our father and son swim shorts. The other prints are in the Venice swim shorts collection.
