The Lowdown
The back half of this run ain’t looking too flash for Eerste Steen, but don’t write it off entirely—there’s a window early in the second week that’s worth paddling out for. The first few days are messy, with wind chopping things up, and the swell direction is holding mostly from the SW, which is solidly exposed here. But the quality is going to be junk until things settle.
Monday the 14th starts off with a 4ft SW swell at 12 seconds, but that N cross-off in the morning doesn’t do much when the period’s a bit jumbled and the water’s a stark 54.7°F—that’s a full 5.4°F colder than normal for this time of year, so you’re going to want the thick rubber, mate. The afternoon drops slightly to 3.3ft, but the wind goes cross and the surface gets lumpy. Nothing doing.
Tuesday the 15th is worse—early on there’s a short, weak 4ft NW windswell at 7 seconds, and the combined energy is weak. By afternoon, it jumps up to 4ft SW, but the period jumps to 16 seconds, and suddenly the energy reads strong. Problem is the wind is fresh cross-shore the whole day, so it’s messy. The long period should be better shaped, but with that angle and chop, it’s just not coming together.
Wednesday the 16th is where it gets real, but not in a good way. Morning sees a solid 10ft SW swell at 13 seconds, with combined energy sitting at a strong 3315. That’s serious size—easily beyond the comfort zone for most, and honestly only for experienced surfers. The wind is cross and strong (40 km/h in the afternoon), so it’s a washing machine. For me, this setup looks more interesting for the kite crew than for paddlers. The afternoon drops to 6ft, but the chop is relentless.
Thursday the 17th, the swell drops a touch to 7ft in the morning, but the wind is still strong, 40 km/h from the SE, and it’s only a cross-off. The combined energy is moderate, and it’s clean on the surface, but the size plus the strength of the wind makes it a tough paddle. The afternoon goes back to 6.5ft and the wind turns cross again—messy. Only the most experienced will even consider it.
Friday the 18th, things ease down to 5ft both sessions, period holding 11-13 seconds, and the wind backs off to 35 km/h cross-off. The morning is clean but the energy drops, and the afternoon is better, but honestly the quality is still poor—too much wind for the size.
Saturday the 19th is the first real glimmer. Morning has 5ft SW at 12 seconds, combined energy moderate, with a gentle 20 km/h SE cross-off. Clean and surfable, but still marginal—I’d call it a 2 out of 10. The afternoon blows out again with 40 km/h cross. So, you get a small morning window.
Sunday the 20th starts with 5ft SW, but the wind is 35 km/h cross, and it’s lumpy. Not worth it.
Monday the 21st is a slight step up: 5ft WSW at 13 seconds, but the morning wind is gentle cross, and the afternoon goes cross-on with a chop. Poor again.
Tuesday the 22nd and Wednesday the 23rd are flat-ish—dropping to 4ft and then 2.5ft, short period, messy. A real lull.
Then Thursday the 24th, we get 3.5ft SW at 13 seconds, with only a moderate cross-off in the afternoon. Still clean, but weak energy. Marginal.
Now here’s the standout. Sunday the 27th is the one to circle. Morning has 5.5ft SW at 13 seconds, combined energy solid, and the wind is only a gentle 15 km/h cross-off—clean, glassy early. The afternoon is even better: drops to 5ft from the WSW, 13 seconds, and the wind is a light 10 km/h cross-off. That’s proper surf. The period’s long enough to hold shape, the size is still fun and not too crazy, and the conditions are clean. This is the best on offer, hands down. It’s a promising call, but it’s still a week out, so keep an eye on it.
After that, Monday the 28th has similar early promise with 4.5ft SW, cross-off, clean, but the energy drops a bit. Still decent, but the afternoon is more marginal.
Then Tuesday the 29th is interesting—a 3.5ft SW swell, glassy morning with zero wind, but small. The afternoon turns onshore and light rain, so quality drops.
So, if you’re keen, target the Sunday the 27th morning and maybe the Monday the 28th morning. There’s also a very brief flash on the

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.
Eerste Steen is 8 km (5 miles) from the very large city of Robben Island. If you plan a holiday in Cape Town, look for hotels and other accommodation in Robben Island. Robben Island has rooms for a wide range of budgets as well as cheap car hire and transport links.
