The Lowdown
Alright, Rusty here, let’s run through what’s coming up at Eerste Steen.
The water’s sitting at 55°F right now, which is about 4°F colder than normal for this time of year – that’s a real chilly anomaly you’ll feel through the wetsuit.
First up, Friday afternoon (7 August) brings a strong SW groundswell at 12 ft with a 14-second period, offshore SW wind at 10 km/h, and combined energy hitting 4370 (moderate to strong). That’s a lot of oomph, but honestly, it’s too big for the break. Skip it unless you want to get worked.
Saturday morning (8 August) is the absolute gem. Swell drops to 8 ft from the SW, still a solid 13-second period, but the wind goes glassy – only 5 km/h from the NNW. The energy is still strong (2221), and conditions are dead clean. This is the best session of the whole forecast – for experienced surfers only, but it’ll be worth the paddle.
Saturday afternoon the wind swings onshore and the swell jumps back to 12 ft. Tight window.
Sunday (9 August) is blown out with cross-shore gusts over 35 km/h and 10 ft of messy swell. Not worth it.
Monday (10 August) is marginal – morning sees cross-off winds with 6 ft swell, but the afternoon gets lumpy.
Now Tuesday morning (11 August) is a good option: offshore E wind at 15 km/h, 7 ft SSW swell, 12-second period, energy at 1174. Clean. Wednesday (12 August) turns excellent – 6 ft WSW swell with a very long 18-second period, offshore E at 15 km/h, energy at 2110. That long-period groundswell will hold up well at Eerste Steen, especially for experienced surfers.
Thursday (13 August) stays top-notch – 7 ft WSW swell, 17-second period, light offshore NE wind, energy at 2964.
The following days from Friday to Sunday drop to 6–7 ft with offshore winds, clean but less energy. Still fun for intermediates.
The final stretch from 19 August onward turns ugly – strong cross-shore winds, and by the 21st and 22nd we’re looking at 15 ft to 21 ft swell with energy over 13000. That’s way out of range for paddling – better suited for kite or windsurfing.
The one to lock in your calendar is Saturday morning 8 August – glassy, 8 ft, clean, and uncrowded. The midweek stretch from Tuesday 11th through Thursday 13th is also quality for the experienced crew. The rest is either average or too big.
Rusty.

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.
