The Lowdown
Alright, Rusty here. Let’s look at what’s brewing for Yzerfontein over the next couple of weeks.
First things first, the water is sitting at 53°F, which is a full 7°F colder than what you’d normally expect this time of year. That’s not just a little chilly – that’s a serious bite. You’ll want a good thick wetsuit and maybe some booties.
The standout session is this Sunday morning, September 6th. We’ve got a solid 7ft swell rolling in from the SW, and it’s packing a hell of a punch – the combined energy is up at 2692, which is strong. But the real beauty is the wind: a clean ESE breeze at 12 mph blowing offshore. That’s going to keep the faces smooth. The period is a very long 18 seconds, meaning this is proper groundswell. On a beach-and-reef setup like Yzerfontein, that long period can make the waves a little straight at the beach, but the reef sections should really line up nicely. It’s going to be powerful, so this is one for the experienced crowd.
After that, Monday morning the 7th is looking glassy with a light W wind at 3 mph and a 6ft SW swell, 14-second period. The energy is still solid at 1418. It’s clean and inviting, but that’s still a decent chunk of water for a learner.
Things quieten down through Tuesday and Wednesday with smaller swell and tricky winds. Then come Thursday the 10th, we see a jump back up – 8ft from the WSW, 16-second period, and the energy is roaring at 3517 in the morning and 3926 in the afternoon. The wind is cross-offshore, so the surf will be clean. However, at 8ft, this is really only for the experts. It’s a solid, powerful swell.
The 11th of September brings a 10ft swell on Friday afternoon, but with an 8-second period – that’s short-period windswell. The energy is still high at 1806, but the wave quality won’t be as good as the groundswells, and that size is again strictly for pros.
We get another window of quality on Saturday the 12th morning – glassy conditions with a 6ft SW swell, 14-second period, and 1665 energy. That’s a great combo for a confident intermediate or expert.
From there, the second week gets a bit messy. There are a few spikes – like the 10ft and 12ft swells around the 15th, 16th, and 17th – but they’re coming with onshore or strong cross-winds that will chop it up. The 16th of September morning has an 12ft SW swell with a cross-offshore wind, which sounds tempting, but that’s a massive, dangerous wave for this break.
The best of the second week actually looks like Monday the 21st of September morning – glassy, 6ft SW swell, 13-second period, with energy at 1449. That’s a good, clean, strong session for anyone who knows what they’re doing. But it’s a long way out, so keep an eye on it.
Overall, this is a stretch where Yzerfontein offers some serious, powerful swells. The best on offer is undeniably this Sunday morning, the 6th – big, clean, and full of energy. Monday the 7th morning is another beauty. After that, it’s a mixed bag of big, tricky conditions, with the 21st of September morning being a promising, but distant, potential highlight.

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.
