The Lowdown
Alright, this is Rusty. Let’s have a look at the next couple of weeks for Eerste Steen. There aren't really any days in the first few that scream "go now", but there's a lot brewing. The water temp is about average for the time of year, nothing weird going on there.
The first real standout comes early on Thursday morning, the 13th of August. We've got a solid 7ft swell from the WSW, with a very long period of 17 seconds, so plenty of energy (2998 combined). That's a proper groundswell. The wind is a cross-off from the NNE at 9 mph, keeping things clean. This is going to be a classic, powerful point break wave, but with that size and power, it's really for the experienced crew only. The long period might make it a bit straight at the beach, but at a reefy point like this, it'll be fantastic.
Friday the 14th and Saturday the 15th are smaller, with the swell dropping to around 6ft-6ft, still from the WSW. Saturday morning is the pick of those two, with glassy conditions and a 3 mph wind from the S. The energy is more moderate now (1184), but still offering fun, chest-high sets. It’s not the biggest, but with the glass, it'll be clean and a bit more manageable for intermediates.
The next big highlight is Monday morning, the 17th of August. The swell bumps back up to 8ft from the WSW, with a 13-second period. The combined energy is strong (2187). The wind is glassy from the SSE at 3 mph. This is another one for the more experienced surfers, as it’s getting overhead and powerful. It’ll be clean and lined up, but the power means it's for the strong swimmers only.
After that, things drop off for a few days through the middle of the week. From Tuesday afternoon the 18th right through to the end of Saturday the 23rd, it's mostly messy or onshore, with the swell being inconsistent or too weak. Thursday afternoon the 20th has a small 4ft swell and an offshore wind, so it might be rideable for a log, but it’s not a main event.
A quick look ahead: the 24th of August (Monday morning) has a bit of a pulse again, with 5ft from the SW, clean with a cross-off, but it’s a moderate energy (1105). Then, the real long-range promise is Friday morning, the 28th of August. We see a big 10ft WSW swell with a 15-second period and glassy conditions. The energy is very strong (4128). It’s way out there in the forecast, so take it with a grain of salt, but if that holds, it’ll be a day for experts only at a spot like this, with some serious, clean walls.
For the best on offer, I'd say Thursday morning the 13th of August. The combination of size, long period, and clean wind at Eerste Steen is hard to beat, especially for the experienced surfer. The second best is Monday morning the 17th of August for a similar, slightly smaller, but glassy session. If you’re an intermediate, the glassy Saturday morning the 15th of August is your best window for a clean, fun session.
Keep an eye on that 28th of August window, it could be the big finale.

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.
