The Lowdown
Alright, let’s get into it.
The next couple of days are looking a bit messy for Yzerfontein, but there’s some real quality coming up if you’ve got a bit of patience. The first proper call to get excited about is Sunday the 13th of September.
Sunday morning the 13th is a standout. Yzerfontein is a beach and reef set-up, exposed to the swell, and we’ve got a solid 7ft groundswell pushing in from the SW with a period of 14 seconds. That’s a good, powerful swell. Combined wave energy is sitting at 1799, so we’re talking moderate to strong energy. The real winner here? The wind is glassy, coming from the ESE at just 3 mph. That’s clean, perfect conditions for experienced surfers. The water temperature is 55°, which feels much colder than normal for this time of year.
Sunday afternoon the 13th will drop off a little. The swell hangs around 6ft from the SW, but the wind swings onshore from the SW at 9 mph, introducing some chop. It’s still surfable but not the same quality.
After that, the forecast gets ugly from Monday the 14th right through to Tuesday the 15th of September. Strong cross-shore winds, lumpy conditions, and dropping swell. This is a gap where I’d stay dry.
Next up, another real highlight lands on Saturday the 19th of September. Saturday morning brings a clean 7ft SW swell with 13-second periods. The combined energy is 1438. The wind is light from the SE at 6 mph, keeping the surface clean. This is excellent surf for experienced surfers. Crowds are sometimes an issue at Yzerfontein, so early is the move.
Then, Monday the 21st of September is a hidden gem. The morning has 6ft from the WSW with a long 15-second period, and the wind is glassy again from the ESE at just 3 mph. Combined energy is 1572. This is another excellent call for experienced surfers. The glassy conditions and that longer period will make for some proper walled-up waves, best handled at the reef sections.
Thursday the 24th of September morning is a big swell event, but it’s too big. We’ve got 10ft from the SSW, combined energy 4292, wind clean from the SSE at 16 mph. That’s expert-only territory. Too much wave for most, so watch from the sand unless you’re really dialled in.
Friday the 25th of September morning is a solid, cleaner option: 6ft SW swell, light SE wind at 6 mph, and combined energy 974. Very good conditions.
The last bit of the run, around the 26th of September, looks small and messy again.
Overall, the best windows are Sunday the 13th morning, Saturday the 19th morning, and Monday the 21st morning. That Monday the 21st is probably the pick of the whole outlook.

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.
