The Lowdown
Alright, Rusty here. Let’s break down what’s cooking for this stretch.
For this forecast period, we’ve got a solid run of South-West groundswell lined up, but the wind is going to be the key factor—sometimes it will clean things up, sometimes it will ruin them. The water temp is sitting right about normal for this time of year, so no surprises there.
The absolute standout of the whole 16-day window, and the one you should plan around, is Eerste Steen on the morning of Sunday, September 13th. You’ve got a clean 7ft swell coming from the SW with a solid 14-second period. The wind is light offshore from the ESE, so expect conditions to be glassy and clean. The combined energy is solid at 1622 (moderate to strong), and the spot is fairly exposed, so it will be handling that SW energy well. This is excellent surf for experienced surfers—the size is significant, so not for the faint of heart, but for those who can handle it, this is the session.
Another highlight is the morning of Thursday, September 24th. Again at Eerste Steen, a clean 6ft SW swell with a 14-second period, light cross-off wind from the SE, and excellent conditions for experienced surfers. Combined energy is 1604 (moderate to strong). This is another proper day—clean lines and good power.
In between, there are a few window dressing sessions. The morning of Saturday, September 12th has a 6ft SW swell with clean conditions thanks to a cross-off breeze. And the Friday, September 18th morning also looks good: a clean 7ft SW groundswell with a light offshore breeze from the east.
But don’t get too excited—the Monday, September 14th and a few days around the 20th and 21st will be blown out and choppy thanks to strong north-west and south-west winds. The second week of the window is a bit more hit-and-miss for quality; the first week is your best bet.
Overall, there are some ripping sessions in here if you can read the wind. Eerste Steen can get crowded, so get there early. The swell size here is often too big for beginners, so this one’s for the intermediate to expert crew.

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.
