The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Eerste Steen over the next couple of weeks.
We’re kicking off with a bit of a slow start, honestly. The first few days – Wednesday the 26th through the 29th – are pretty average. The swell is hanging around 4ft to 5ft out of the WSW and SSW, but the wind is all over the place, mostly cross or cross-onshore, and the water’s running a bit colder than usual for this time of year at 57°. The energy is moderate to strong (1104 to 1029), but the conditions just aren’t dialled in. Wait for it.
The first real standout is Sunday the 30th. Do yourself a favour and get up early. The morning is looking glassy with a light offshore breeze, and a solid 7ft WSW swell rolling in with a period of 13 seconds – that’s proper groundswell energy (1617). This one’s got some punch, so it’s more for the experienced crew. The waves will be clean and grunty, but it’s a bit much for beginners.
Then we’ve got a big one brewing for the start of September. Tuesday the 1st is looming large – we’re talking 10ft to 12ft of SW swell with a 13-second period. The combined energy is huge (2744 to 3883), but that’s pushing it for this break. The morning is cross-shore with a moderate breeze, and by the afternoon, it’s honestly too big for comfortable paddling here. The wind and tide are favourable, but the swell is predicted to be too big for Eerste Steen, so only absolute experts with a death wish need apply. Thursday the 3rd is a write-off with near gale-force winds.
After that blowout, the surf settles down. Friday the 4th morning is a nice little window – 8ft of S swell, clean with a light offshore, and the energy is still strong (1440). That’s a good one for experienced surfers, but the afternoon gets choppy again.
The second week fades out. From the 6th onward, the swell drops away to under 3ft, and the energy gets weak (736 down to 172). The wind is mostly onshore or cross, and conditions are poor. There’s a tiny glimmer on the 10th with a clean 3ft SW swell, but it’s wafer-thin. Honestly, the first week has the goods, the second week is a waiting game.
Stay stoked,
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.
