The Lowdown
Righto, grab a coffee and settle in, because we’ve got a long-range look at Eerste Steen, and it’s a bit of a mixed bag. This spot is a fairly consistent, intermediate-level reef or point, exposed to the southwest swell. The water temperature is sitting at 52°, which is a whopping 8° colder than usual for this time of year – that’s seriously unusual, so you’ll want a thick wetsuit, no question.
We’ve got a bit of a wait for the first decent wave. Monday afternoon kicks off with a solid 6ft southwest swell, period at 13 seconds, and light southwest offshore winds. That’s a clean start, but the energy is already moderate (1069), and the forecast says it’s marginal. The real standout window looks like it’s shaping up for the weekend. Saturday morning, September 10th, sees a 8ft southwest groundswell, period 15 seconds, with light southeast cross-offshore winds. The energy is strong (2411), and it’s clean. However, that’s a bigger swell, pushing into expert territory, and the long period might make it a bit straight at the beach – but Eerste Steen is a reef, so it should handle it well. Expect crowds to be possible.
Sunday morning, September 11th, is the highlight. You’ve got a 7ft southwest swell, 14-second period, gentle southeast cross-offshore breeze, and the conditions are described as excellent for experienced surfers. The energy is strong (1646), and the wind is clean. This is the one to circle. After that, the middle of the week gets messy with strong winds and lumpy conditions, so it’s a skip.
Looking further out, the second week has a few promising moments. By Friday, September 16th, the swell drops to a more manageable 7ft, period 13 seconds, with fresh southeast cross-offshore winds and clean conditions. The energy is strong (2145). And then Saturday, September 17th, has a lighter 4ft swell, period 12 seconds, with a light southeast breeze and clean conditions – a good option for a smaller board. Just keep in mind that long-range forecasts are a bit less certain.
So, overall, the best bet is Sunday morning, September 11th, with that 7ft southwest groundswell and clean offshore winds. Saturday morning, September 10th, is also a solid, bigger option for the experts. The rest of the period is a constant battle with wind and chop, so pick your windows carefully.

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.
