The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking for the next couple of weeks.
We’ve got a bit of a wait on our hands right now, with Monday 3 August being the first real sniff of a wave. The whole forecast starts off with a solid pulse of SW groundswell, but it’s a slow burner in terms of quality. The standout window is shaping up to be the middle of next week, specifically Wednesday 12 August and Thursday 13 August, where the combination of size, period, and winds looks the most exciting. There's a big gap around the 8th to the 9th where the wind gets messy and it's not worth paddling out, then it cleans up again. For the second week, the outlook gets a bit rougher and less reliable.
Let’s get into it.
Monday 3 August starts with clean conditions at Eerste Steen. That morning, the ENE wind is glassy offshore, and we’ve got a 4.6 ft SW swell with a nice 12-second period. The water is sitting at 55.4°, which is 4.3° colder than normal for this time of year. That chilly water anomaly is very unusual, so grab a thicker wetsuit. The combined wave energy is moderate at 805. That morning session is the pick of the day, with clean faces. By the afternoon, the wind swings to a light cross-onshore and quality drops off.
Tuesday 4 August is another early-bird call. The morning is glassy again with a 3 mph easterly breeze, and the swell holds at 4.6 ft from the SW with 11-second period. The energy dips to 484, so it’s a little weaker, but fine for an intermediate. The afternoon sees a cross-onshore wind and smaller waves.
Wednesday 5 August – This is a day where the raw power ramps up, but the wind doesn’t play nice. The swell jumps to 6.6 ft from the SW, with a very long 16-second period, pumping the combined energy up to 2046. But a moderate cross-shore breeze from the NNW at 12 mph will put a chop on it. This is a lot of juice, but for the beach/reef setup here, that long period might make it break a bit too straight for the sandbanks. Probably better for more experienced surfers only, given the size.
Thursday 6 August is a major highlight. The morning shows a clean 9.8 ft SW swell with a 13-second period, and a light cross-offshore wind from the SE at 6 mph. The energy is very strong at 3348. This is big, powerful, and clean – excellent for experienced surfers. It’s over 8 ft, so keep that in mind. The afternoon gets a light cross-onshore, so the morning is the clear call.
Friday 7 August – Deja vu. Another morning with 9.8 ft SW swell, 14-second period, and a light cross-offshore wind from the SE at 6 mph. The energy is even higher at 3621. Again, this is excellent and a standout for more advanced crew. The afternoon goes cross-onshore.
Saturday 8 August and Sunday 9 August are a write-off for the most part. Swell is still solid, but on Saturday we get onshore winds and on Sunday we get strong cross-shore winds up to 28 mph that will absolutely mess up the surface. The energy is still high, but it's a battle. Not worth it for a paddle surfer – that Sunday setup actually looks more interesting for kiting, if that’s your thing.
Monday 10 August – A big clean-up. The morning delivers a 4.6 ft SW swell with a light cross-offshore wind from the SE, leaving clean surf. Energy is down to 783, so it's more manageable. A good, fun option if you want a break from the bigger stuff.
Wednesday 12 August – This is the absolute top shelf of the forecast. The afternoon is where it’s at: 5.2 ft from the WSW but with a ridiculously long 20-second period, producing a very strong energy reading of 2012. The wind goes glassy, totally calm with 3 mph from the WSW. That’s a dream combo: clean, long-period groundswell, perfect conditions. The morning is also fine but a slight cross-onshore is there. The afternoon is the session.
Thursday 13 August – Potential, but huge. The swell jumps to 11.5 ft from the WSW with a 17-second period, and the combined energy is through the roof at 5798. The wind is a light cross-shore from the SSE. The forecast says it may be too big for this break, and honestly, at 11.5 ft with that power, this is for experts only, and even then, it might be a washing machine. Only for the brave.
Friday 14 August remains big, around 9.8 ft, with decent winds, but the swell is still huge and

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.
