The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what Yzerfontein’s got cooking for us over the next couple of weeks. It’s a mixed bag, and we’ll need to pick our moments.
The opening stretch is a bit of a grind. We’re looking at a solid pulse of WSW and SW swell rolling in from Monday the 17th, with wave heights in that 8 to 8ft range and periods around 13 seconds. But the wind is just a mess – cross, onshore, cross-shore chop – it’s not doing us any favours. The combined swell energy is massive, but the quality is poor. You’ll be fighting cruddy conditions for little reward. Honestly, this is more of a kitesurfing show than a paddle gig.
Tuesday the 18th and Wednesday the 19th are much the same story: 8ft to 8ft of SW swell with moderate cross-shore winds and a chop. The energy is still high, but the ride quality is just not there. We’re in a holding pattern.
Now, Thursday the 20th is where it gets interesting, but not for everyone. We’ve got a big 10ft SW swell with a 13-second period, and the wind is clean on Thursday morning with a cross-offshore SSE breeze. That’s a beautiful combo for clean faces. But let’s be real – 10ft is only for the experts. If you’ve got the chops, this is the standout, but it’s not a beginner’s game. The energy is rattling the cage.
Friday the 21st drops back to 6ft, but the wind is up and cross-shore again, so the quality slips away. Saturday the 22nd is small and weak with 5ft and light cross-shore wind. Not much to shout about.
Finally, we get a proper window. Sunday the 23rd morning has clean, cross-offshore wind and a 6ft SSW swell with a lovely long 13-second period. The energy is pumping, but it’s a long-period groundswell, so at a beach-and-reef spot like this, it might bend a bit straight. For the sharper reef sections, it’ll be gold. This is the best on offer in the first week for a standard surfer.
Monday the 24th morning has clean 7ft SSW swell with a nice cross-offshore breeze. It’s worth a look.
Then we hit a weird one. Tuesday the 25th morning shows a tiny 2ft swell but with an incredible 24-second period! The combined energy is still decent. That’s a super long-period groundswell. It’ll be clean with light winds, but you’ll be waiting for those sets. A real challenge, but a beautiful one for the patient surfer on the right bank.
Wednesday the 26th rolls through with 8ft SW swell and onshore wind. Not great.
The real hidden gem might be Tuesday the 1st of September morning. We’ve got an 8ft SW swell, a 14-second period, and the wind is perfect offshore from the E. The combined energy is very strong. That’s a proper clean, powerful day for the experienced crew. Mark it down if you can wait.
Overall, the standout is Thursday the 20th for the big-wave chargers, and Sunday the 23rd morning for everyone else looking for clean, powerful waves. The water temp is about average for this time of year, nothing unusual.
Stay salty,
Rusty

Information about the Yzerfontein Surf forecast
The above surf forecast table for Yzerfontein provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Yzerfontein can be found by selecting the local surf guide option on the grey menu. Our Yzerfontein 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 (Yzerfontein) 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 Yzerfontein 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.
Yzerfontein is 39 km (24 miles) from the city of Saldanha. If you plan a holiday in West Coast, look for hotels and other accommodation in Saldanha. Saldanha has rooms for a wide range of budgets as well as car hire and transport links.
