The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming down the line for Eerste Steen. It’s not a straightforward run, but there are some windows that’ll get the heart pumping.
Straight up, the first few days are a bit of a write-off. We’ve got a solid SW groundswell running, but the wind is just not playing ball. Tuesday 1st and Wednesday 2nd are seeing a powerful 8ft to 10ft SW swell, with a long 13-second period, and the combined energy is massive (2429-3208). But it’s all cross-onshore, making it choppy and messy. That’s a lot of water moving around for not much reward. On Wednesday 3rd morning, the swell drops to 6ft but the wind is still cross-on, so it’s not worth the paddle. Thursday 3rd afternoon, the wind shifts to a clean cross-off, but the swell is a short-period 8ft from the S with only 9 seconds – it’s just not the same quality.
The real story starts to turn around Sunday 6th. The morning is still a bit marginal, but look at the afternoon: a clean 3ft SSW swell, with a *very long* 19-second period. That’s proper groundswell energy (1460). The wind is light and cross-off, so the face will be clean. That’s a beautiful, long-period wave for the experienced surfer – it’ll wrap in nicely, but it might be a bit too straight for a beach break, so keep your eyes on the point. This is a standout session.
Then, Monday 7th morning is a gem. Glassy conditions, a 5ft SSW swell, 13-second period, and the combined energy is solid (786). The wind is just a slight air from the NE. That’s a magic window – clean, lined-up, and well-shaped. The water is sitting at 55°, which is a whopping 5° colder than normal. That’s very unusual, so you’ll want a thick suit.
After a few days of flat, small, and poor conditions, the next big one is Thursday 10th. The morning looks absolutely incredible: glassy, a 7ft WSW swell, with a 15-second period. That’s a serious, powerful groundswell (1795). It’s a bit on the bigger side – good for experienced surfers, will be a handful for less confident paddlers. This is the other standout.
The following week has some smaller, more marginal swells with mixed winds. There’s a bit of a pulse on Monday 14th afternoon with a 5ft SW swell, but it’s onshore. The end of the run on Wednesday 16th has a 5ft SSW swell with a 12-second period and light onshore wind, which could be worth a look if you’re local.
So, to sum it up: the first week is a battle with the wind, but the standouts are crystal clear. Sunday 6th afternoon is a clean, long-period treat for the experienced surfer. Monday 7th morning is a glassy, all-round good session. And Thursday 10th morning is the big, powerful glassy groundswell that will have the better surfers smiling. Get out there when it’s clean.
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.
