The Lowdown
Right, let's have a look at what's on the cards for the next couple of weeks, focusing on Eerste Steen. It’s a mixed bag, to be honest. The water’s sitting at 53°F, which is a solid 7°F colder than what’s normal for this time of year, so you’re going to want the thickest hood and gloves you’ve got. It’s properly unusual, that cold.
Right off the bat, there’s nothing worth paddling out for on Wednesday. We’re looking at small, weak swell around 3ft with a light cross-onshore breeze. It’s a bit of a flat, bumpy mess. You can give that a miss.
Thursday and Friday see a bit more push, with swell building from the 8ft mark on Thursday morning, but the wind is cross-shore and it’s looking messy. The energy is moderate (2215) on Thursday morning, but the waves are going to be chopped up. Friday is similar, cleaner lines (1124) but still not offering much in the way of quality. It’s a lot of effort for marginal waves.
Come Saturday, the swell is still there, around 6ft in the morning with a clean cross-off breeze and a big jump in energy to 2288. That’s looking like the first real chance to get a few. But the standout, for sure, is Sunday morning on the 13th. The swell is a solid 7ft from the SW with a 14-second period, and the wind is forecast to be glassy – just nothing at all. The energy reading is strong at 1542 and the conditions are being called excellent for experienced surfers. That’s the window you want to be in the water. The beach break might get a bit straight with that period, but when it’s glassy like that, you’ll take it.
After that high, it gets a bit wild. Monday sees the wind crank up and the onshore junk arrives, making a mess of things. Then we’ve got a big pulse of energy mid-week. Wednesday the 16th is a serious case of “so close, yet so far.” We’re talking a solid 12ft of SW swell with a huge energy reading of 5371. But, it’s just too big for this spot. It’s a washing machine, and only for the truly unhinged. After that, Thursday and Friday are back to average, mediocre conditions.
The following week, starting Monday the 21st, shows a bit of promise. The energy is lower, but Monday afternoon is looking clean with a cross-off breeze and a 5ft swell. The real gem in the second week is Tuesday morning, the 22nd. The wind is forecast to be calm, completely glassy, with 5ft of SW swell. It’s not huge, but for a clean, fun morning session it could be the pick of the week. After that, it’s a slow slide into smaller, wind-affected surf for the rest of the period.
So, to keep it simple: if you can only get out once, make it Sunday morning the 13th. That’s the standout for size and cleanliness. If you miss that, Tuesday morning the 22nd is your next best bet for some smooth, user-friendly waves.

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.
