The Lowdown
Alright, Rusty here, let’s talk about what’s coming up for Eerste Steen. Right now, the water is sitting at a chilly 55°F, and that’s a whopping 5°F colder than normal for this time of year – that’s a serious bite in the air and the water, so you’ll want the thickest wetsuit you’ve got.
The first few days are a bit of a write-off, if I’m being honest. Friday and Saturday are plagued by a fresh cross-offshore wind and a lumpy, short-period swell that’s just not lining up. The combined energy is there, but the quality just isn’t. We’re looking at a gap of a couple of days with nothing worth paddling out for.
Now, hold onto your board, because Sunday morning, 6th September, is the real standout of this whole outlook. The swell is a solid 7ft, but it’s not just any swell – it’s a long-period groundswell from the SW at 18 seconds. That’s a proper, powerful pulse rolling in, and with a gentle ESE breeze keeping it clean, the wave face is going to be smooth. The combined energy is a massive 2877, so there’s plenty of grunt behind it. That’s the session to circle on the calendar.
Sunday afternoon pulls back a touch, with the swell dropping to 6ft and the period shortening to 16 seconds, but it’s still a decent wave. The wind goes a little cross, so it won’t be as pristine as the morning, but it’s still rideable.
Monday and Tuesday are a mixed bag. Monday sees a cross-onshore breeze that messes with the shape, but the swell holds in the 6ft to 6ft range with a good 13-14 second period. Tuesday morning is a real tease – glassy conditions with a 4ft SSW swell, but it’s not quite enough to get the blood pumping. The energy is a low 617, so it’s on the weaker side.
The middle of the week (Wednesday and Thursday) is pretty average. The swell drops off further, and the wind is mostly cross-onshore. Not worth getting excited about.
Then, a big pulse rolls in for the weekend of the 12th and 13th. Saturday morning, 12th September, has a 8ft SW swell with a 14-second period and a clean cross-offshore breeze – that’s a solid combo. The energy is pumping at 3311. But Saturday afternoon, the swell jumps to 12ft from the SSW. That’s too big for this break, and the forecast flags it as too big. It’s going to be a washing machine out there, so unless you’re a seasoned charger looking for a tow-in, give it a miss.
The following week is a bit of a fade. Sunday and Monday offer some smaller, clean waves in the 3ft to 6ft range, but with the swell direction shifting around, it’s nothing to write home about. By Tuesday and Wednesday, the wind turns nasty from the NNW, making it messy and lumpy, and the swell is short-period again.
The very end of the outlook, on the 18th and 19th of September, has another big swell spike – 13ft on Friday morning – but again, it’s flagged as too big for this spot. That’s a kite-surfing day, not a paddle-surfing one.
So, to wrap it up: the one true stand-out is Sunday morning, 6th September. That long-period SW groundswell with the clean offshore breeze is your best bet. The Saturday the 12th is also a good call for the morning session, but be ready for it to get out of hand in the afternoon. The rest of the window is a mix of average to poor conditions, with some days that are simply too big for comfortable surfing.
Rusty out.

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.

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.
