The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming up for Eerste Steen. The wait is finally over and there’s a bit of a slow start, but once we get past the first few days, this stretch has some real magic lined up.
The water’s sitting at 56°F right now, which is a bit colder than normal for this time of year, so you’ll want a good steamer.
We’re kicking off from Sunday 9th August, but honestly, you can forget about paddling out. There’s a chunky 10ft SW swell with a 12-second period, but that SSE wind is screaming at 25 mph cross-shore, making a total mess of things. The wave energy is strong (2724), but it’s not surfable. Monday 10th isn’t much better – still cross-shore winds and a lumpy 6ft SW swell. Not worth your time.
Tuesday 11th, we start to see a glimmer. The morning brings a cleaner 6ft SSW swell (12s period) with a gentle E breeze, cross-off. It’s still not a standout, but it’s getting closer. The wave energy is moderate (1137). By Wednesday 12th, things really start to light up. The morning has a 6ft SW swell, and the wind goes offshore from the east at 9 mph. The swell period jumps to a very long 18 seconds – that’s proper groundswell energy, and the wave energy is strong (2343). The afternoon is even better: glassy conditions, 6ft WSW swell, same long 18-second period. This is excellent surf for experienced surfers, and the clean conditions are a dream. This is a true standout.
Thursday 13th keeps the stoke going. Offshore winds from the NE in the morning on a 7ft WSW swell with a 16-second period. Wave energy is very strong (3245). The afternoon is equally clean with a 6ft WSW swell and 18-second period. This is world-class quality for the crew who can handle it.
Friday 14th and Saturday 15th are still good, but not as epic. Clean conditions with offshore or cross-off winds, and consistent 6-6ft WSW swell, but the periods drop back to 14 seconds. Still very surfable, but the real magic is behind us.
Sunday 16th is a bit of a mixed bag – morning is clean with a 6ft WSW swell, but the afternoon wind swings onshore. Then Monday 17th morning delivers another gem: glassy conditions, an 8ft WSW swell with a 13-second period, and strong wave energy (2323). That’s a big, powerful swell – experts only. The afternoon gets a bit lumpy with onshore wind.
After that, conditions get shaky again. Tuesday 18th sees cross-shore winds and a drop in size. The rest of the week into the weekend is mostly marginal – onshore or cross-shore winds, and the swell size stays around 5ft to 6ft, but the quality is poor or marginal. The wave energy drops off significantly, often below 1000. There’s a brief flash on Wednesday 19th afternoon with a clean 5ft WSW swell and a 15-second period, but it’s not the same as the mid-week run.
The standout days are definitely Wednesday 12th and Thursday 13th. That Wednesday morning with the offshore wind and very long-period groundswell is the pick of the whole forecast. The break is fairly consistent here, and even though it gets crowded sometimes, the quality on those days will be worth the company.
Rusty out.

Information about the Eerste Steen Surf forecast
The above surf forecast table for Eerste Steen provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Eerste Steen can be found by selecting the local surf guide option on the grey menu. Our Eerste Steen surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Eerste Steen) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Eerste Steen may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Eerste Steen is 8 km (5 miles) from the very large city of Robben Island. If you plan a holiday in Cape Town, look for hotels and other accommodation in Robben Island. Robben Island has rooms for a wide range of budgets as well as cheap car hire and transport links.
