The Lowdown
G’day, I’m Rusty, and I’ve got the lowdown on the next couple of weeks at Eerste Steen. It’s a mixed bag, but there’s a couple of windows that’ll get the blood pumping.
We start off from Thursday the 20th of August, and it’s a bit of a slow grind. The first few days are looking marginal, with a solid 10ft SW swell on Thursday but the wind is cross, so it’s gonna be a bit scratchy. The combined energy is strong at 3422, but it’s not lining up perfectly. Swell drops a bit Friday, and the onshores creep in Saturday afternoon. The water temp is about average for the time of year, so don’t stress about a wetsuit.
The real standout is Tuesday the 25th of August. The morning session is looking clean, with a 7ft SW swell, 14-second period, and a cross-off breeze. The combined energy is strong at 1804, and it’s rated excellent for experienced surfers – this is a serious window. The swell direction is right on the optimum from the SW, and the wind is offshore-friendly. Crowds are possible here, so get in early.
Friday the 28th of August also has a promising morning with a 7ft WSW swell and clean cross-off wind, but the afternoon goes downhill with a choppy onshore. The last week is a mixed bag of strong winds and lumpy seas, so don’t get your hopes up too high for consistency.
The absolute gem is Monday the 31st of August. We’ve got a 12ft WSW swell, 13-second period, and a glassy early morning wind. The combined energy is massive at 4241, but it’s a big one – over 8ft, so this is for experts only. The break is fairly exposed, and with that size, it’ll be a proper challenge. The cross-off breeze keeps it clean, but it’s a heavy paddle.
Overall, Tuesday the 25th and Monday the 31st are your best shots. The rest is a bit of a wait-and-see, with a lot of cross-shore winds and chop. Stay sharp, and don’t sleep on those morning windows.

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.
