The Lowdown
G’day, Rusty here. We’ve got a real mixed bag coming up at Eerste Steen over the next couple of weeks. The water’s sitting at 55.8° right now, which is a solid 4° colder than usual for this time of year – you’ll want a good steamer.
The outlook kicks off from Saturday, August 1st with clean, small waves. Saturday morning is your go: a clean 3.9ft SW groundswell with a period of 14 seconds, light offshore breeze from the ENE, and the energy is moderate (585). Nice and clean, but you’ll be searching for the better sets. The afternoon turns choppy, so make the most of the morning.
Sunday the 2nd keeps the same 3.9ft SW swell, but the wind goes cross-off in the morning from the N, staying clean. However, the period drops a touch to 13 seconds – still workable, but not as juicy as Saturday morning. The afternoon gets a direct onshore from the WSW, so call it early.
Now, Monday the 3rd – this is the first real standout. We’ve got a 4.6ft SW groundswell, 12-second period and glassy conditions in the morning with a NNE breeze so light it’s barely there. The energy bumps up to a solid moderate level (795). This is clean, fun surf and it’s the best small-wave window in the whole outlook. The afternoon goes cross-on, so hit it early.
Tuesday the 4th sees a drop-off. Morning is cross-off and clean with 4.6ft SW swell, but the energy is back down to 483. Worth a paddle if you’re keen, but it’s not a standout.
Come Wednesday the 5th, the swell jumps. Morning brings 6.9ft SW groundswell at 14 seconds with a clean, cross-off NW wind – but it’s blowing 15.5 mph, so it’s a bumpy clean-up. The energy is strong (1792). This one’s for intermediate surfers who can handle a bit of punch. By the afternoon, it’s a 9.8ft WSW swell, cross-shore wind at 15.5 mph, and the energy shoots up to 3767 – messy cross-chop and big, so not one for the faint-hearted.
Thursday the 6th and Friday the 7th get big and messy. Thursday sees 13.1ft WSW swell, cross-shore winds, and energy over 5500. It’s too big for Eerste Steen. Friday is 9.8ft SW groundswell at 13 seconds, but with a weak onshore flow. Not recommended.
The weekend of the 8th and 9th is a write-off. Saturday the 8th has 11.5ft SW swell with a fresh cross-onshore 21.7 mph breeze – messy, lumpy, and the energy is over 4000. Sunday the 9th is even bigger: 19.7 to 21.3ft SSW swell, energy over 12,000, and though the wind is cross-off from the SE, this is expert-only territory and honestly too big for the break. Kite surfers might be eyeing it, but for paddle surfing, it’s a no-go.
Monday the 10th stays huge: 18ft S swell in the morning, clean cross-off, but energy over 8000. Afternoon stays 14.8ft with lumpy cross-shore. Still too big.
Then we get a proper reward. Tuesday the 11th morning is still massive (16.4ft SSW, 12,000+ energy, clean cross-off – experts only). But Tuesday afternoon – bingo. The swell drops to 8.2ft S swell at 12 seconds, the wind goes glassy from the SSW, and the energy is still strong but manageable (3434). This is excellent for experienced surfers. That’s a standout session.
Wednesday the 12th morning is a treat: 5.2ft WSW groundswell with a very long 18-second period, clean cross-off from the SE, energy at 2959. That’s a groundswell gem – glassy conditions, proper lines, and that long period will wrap beautifully. Best for the point and reef setups, as it might be a bit straight for a beach break. Afternoon goes cross-on, so get in early.
Thursday the 13th morning keeps it clean: 5.9ft WSW groundswell, 15-second period, cross-off ESE breeze, energy 1613. Another excellent window for experienced surfers. The long period is still in play, so again, points and reefs will shine.
Friday the 14th morning is solid: 4.6ft SW groundswell at 14 seconds, clean cross-off wind, energy 781. Very good conditions. The afternoon gets a bit messy with a light cross-on.
The final standout to watch is Saturday the 15th morning: 7.2ft WSW groundswell at 14 seconds, clean offshore ENE breeze at 6.2 mph, energy a healthy 1787. This is excellent for experienced surfers – clean, powerful, and the wind is off it all morning.
Sunday the 16th goes huge again – 14.8 to 18ft

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.
