The Lowdown
Alright, Rusty here, let's take a look at what Yzerfontein has cookin' for us.
Right off the bat, don't get too excited for this coming weekend. Saturday, September 12th, is a write-off for paddling. We've got a solid 6 to 8ft SW swell with massive energy (1847 to 3629), but that 19 mph SSE cross-off wind is just gonna wreck any chance of a clean wave. It's a no-go.
Sunday the 13th is where it starts to get interesting. The morning is a real standout. We're looking at a clean 7ft SW groundswell (energy 1750), and the wind swings perfectly offshore from the East at a light 6 mph. That's a magic combination for Yzerfontein (beach and reef). The water is sitting at a very unusual 55°, which is 5° colder than normal for this time of year, so you'll want a good thick suit and booties. This is excellent, but the 7ft swell is getting up there, so it's for the experienced crew. The afternoon stays clean with a light breeze, but the wind goes cross-on, so the morning is the clear call.
After that, we hit a rough patch. Monday the 14th through Tuesday the 15th is a total loss with strong, lumpy cross-onshore winds and dropping swell. Then Wednesday the 16th offers a real tease. The morning session shows a massive 10ft SW swell (energy 4313) with clean, cross-off winds. That's proper, heavy, expert-level juice with a very long 14-second period. But the data says it's predicted to be too big for this break. If you're not a charger, sit this one out.
The next real highlight isn't until Sunday, September 20th. The morning is another beauty: clean 6ft SW swell (energy 1144) with perfect light offshore wind from the East. It's a smaller, cleaner version of the 13th, and it's excellent for experienced surfers again.
After that, the outlook fades. From Monday the 21st onward, the swell drops off, the wind gets messy, and we get long periods of no good surf, especially around the 22nd to 24th. There's a pulse of bigger, longer-period swell around the 26th and 27th, but it's plagued by strong cross-shore winds making it lumpy and poor. Not worth paddling out for.
So, for the 16-day window, the absolute standouts are Sunday morning, September 13th, and Sunday morning, September 20th. Both offer clean, powerful SW groundswell with offshore wind. The 13th has more size and grunt, the 20th is a bit more manageable, but both are top-tier for the experienced surfer. Don't bother with the rest.

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.
