The Lowdown
Alright, let me break down what’s coming for Eerste Steen. This forecast has some solid pulses, but you’ve gotta pick your moments.
Sunday the 13th of September kicks off with a proper SW groundswell at 7ft with a long 14-second period. The combined energy is 1890 – plenty of juice. A light north cross-off breeze at 6 mph is keeping it clean. This is excellent surf for experienced surfers only; that size is pushing it for anyone not confident. Water temp is 56°F, which is much colder than normal, so suit up good.
Sunday afternoon the wind swings onshore and the quality drops fast. Monday and Tuesday are mostly blown out with strong NNW winds at 19 mph creating lumpy, messy conditions. A gap in quality holds until Thursday the 17th of September morning, when the swell drops to 6ft and a cross-off from the SE at 12 mph cleans things up. It’s still marginal, but the surface is clean.
The first real standout is Saturday the 19th of September morning. Swell at 5ft from the SW, 12-second period, with only a 3 mph cross-off breeze. The energy is 1031, and it’s forecast as very good conditions. That near-calm wind will make for glassy, fun waves. Crowds are possible, but not guaranteed.
The next big highlight is Tuesday the 22nd of September morning. Swell builds to 6ft from the WSW with a 13-second period, but the wind is glassy – zero wind. The combined energy jumps to 1721, and it’s rated excellent for experienced surfers. That glassy surface on a longer-period swell will be a treat, especially at a setup like this.
Thursday the 24th of September morning also looks solid with 7ft SW swell and a light cross-off. Clean conditions again.
The end of the forecast on Monday the 28th of September shows a massive 12ft pulse from the SW, but the wind is howling cross-shore at 22 mph, and it’s just too big for this break. Stay home that day.
Your best bets are Saturday the 19th and Tuesday the 22nd mornings – clean, solid, and well worth the paddle.

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.
