The Lowdown
Alright folks, Rusty here. Let’s have a good look at what Eerste Steen has on offer. We’ve got a solid run of surf coming up, starting this Tuesday, August 11th, and stretching right through to the end of the month.
The overall pattern is looking promising. We kick off with a decent pulse of SSW groundswell that holds for a few days, then it backs off a bit before a bigger, more powerful WSW swell rolls in towards the end of the first week and into the second. There are a few days in the middle where the conditions get a bit tricky, but there are some real gems to pick out.
For the standout, I’m looking at Wednesday, August 12th. The morning session is looking prime. We’ve got a clean 5.6ft SW groundswell with a proper 18-second period – that’s long-period energy that’ll wrap in beautifully. The wind is offshore from the east at 12 mph, keeping the faces clean as a whistle. The combined energy is strong at 2244. This is expert territory with that size and power, but the quality is top-notch. The afternoon cleans up again with a cross-off breeze and 5.9ft swell, still with that lovely 18-second period.
Tuesday the 11th is a great warm-up. A 6.6ft SSW swell with 12-second period and a cross-off ESE breeze will have you stoked for the morning. By the afternoon, the wind goes light offshore from the east, and the swell drops slightly to 5.2ft. Very clean conditions with moderate wave energy (1385).
After that mid-week peak, the swell hangs around but the wind gets more challenging. Thursday the 13th is a bit of a write-off with a lumpy cross-onshore breeze in the afternoon. Friday the 14th, however, is a hidden gem. The morning sees a light cross-off breeze from the NNE with a clean 5.9ft WSW swell. But the afternoon is pure magic – glassy conditions, no wind at all, and the same 5.9ft swell. That’s the kind of session you dream about. Moderate energy (1393).
Saturday the 15th starts clean again in the morning with a cross-off breeze, but the afternoon turns onshore and messy. Sunday the 16th is another glassy morning, with calm winds and a clean 5.2ft WSW swell. Moderate energy at 1047. The afternoon gets a light cross-onshore breeze, so go early.
Then we hit a bit of a rough patch. Monday the 17th and Tuesday the 18th see the swell size jump up to 8.2ft and 9.8ft, but with lumpy cross-shore winds and some poor conditions, especially Tuesday afternoon when a fresh southerly breeze kicks up to 22 mph, creating lumpy cross-chop. The wave energy is high (2581), but the quality drops off. This setup at a beach-and-reef spot like Eerste Steen might be more interesting for kite surfing than paddle surfing.
We get a clean-up on Wednesday the 19th with a morning cross-off breeze and a 7.2ft S swell. That’s good for experienced surfers. The afternoon fades with a short, weak 7-second period.
Thursday the 20th and Friday the 21st see the swell drop right off to around 3.9ft, with clean but weak surf. Friday gets blown out by a strong north wind.
Now, looking into the longer range – Saturday, August 22nd, we get a glassy morning with a 5.6ft WSW swell and a 15-second period. The energy is strong at 1704. That’s a promising one, but it’s a week and a half out, so treat it as a hopeful eye on the calendar.
Sunday, August 23rd, is looking like another proper standout for the second week. A clean 8.2ft WSW groundswell with a 15-second period, combined with a light cross-off ESE breeze. The combined energy is very strong at 3219. That’s expert-only territory, but if it holds, it’ll be one of the best swells of the whole run. The afternoon gets a cross-onshore breeze, so hit it early.
After that, the swell slowly fades into the following week, with smaller, cleaner days on the 24th and a final clean pulse on Wednesday the 26th with a 6.2ft SW swell and a cross-off breeze.

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.
