The Lowdown
G'day, Rusty here, and I've been staring at the charts for Yzerfontein. The next couple of weeks look like a bit of a mixed bag, with a lot of swell but also a lot of wind. The real standout is a very specific window early next week, but we'll get to that.
The water is sitting at 53°, which is a massive 7° colder than normal for this time of year. That's proper winter water, so you'll want a thick wetsuit, maybe even boots.
Right now, the first real surf on offer is kicking off on Friday the 4th of September. There's a solid 10ft S swell with moderate energy (1351) but it's coming in with a 22 mph SE cross-off wind. The chart says it's clean, but that swell is predicted to be too big for the break, so unless you're a seasoned charger, give it a miss.
Saturday morning and afternoon, the 5th, sees the swell drop to 6ft - 6ft from the S, but the ride is marginal. The wind stays cross-off, but the energy is moderate (537-693). Honestly, it's not looking like the best bet.
Now, Sunday the 6th of September is the standout. The morning shows a 7ft SW groundswell with a very long period of 18 seconds and a massive energy reading of 2655. The wind is a gentle offshore from the ESE at 9 mph. The chart is calling it "excellent surf conditions for experienced surfers". This is the one. That long period from the SW means the point and reef setups at Yzerfontein (beach and reef) will be firing. The 7ft is enough for a good session, but it's over 5ft, so beginners might find it a bit much. The afternoon sees the swell drop to 6ft and the wind goes light cross, which is still okay but the magic is gone.
Monday and Tuesday are okay but not epic. Monday the 7th has a 6ft SW swell with a good period of 14 seconds, but the wind is a light cross-on from the WNW and WSW. The energy is still strong (1418-1077), but it's not as clean. Tuesday morning the 8th drops to 4ft from the SSW with a 12-second period, but the wind turns glassy – 3 mph from the WSW. It's a small window of perfection, but the energy is weak (536). The crowd factor is listed as "sometimes," so you might find a few others out.
From Wednesday the 9th through to the end of the first week, the swell drops off to 3ft - 4ft, and the winds turn cross or onshore. The energy is weak (292-355). It's a bit of a flat spell with poor conditions.
The second week starts to ramp up again. Thursday the 10th sees a 5ft SW swell with 19 mph cross wind, which is lumpy. The energy is moderate (1545), but it's messy.
Friday the 11th has a 10ft S swell with a short period of 8 seconds – that's a windswell. The energy is high (2123) but the wind is 22 mph cross-off. It's clean, but again, too big for the break. Saturday the 12th is a big one: 10ft SW groundswell with a 17-second period, and glassy conditions in the morning. The energy is massive (4985). This is a serious swell for experts only. The afternoon is 12ft with an onshore breeze, so that's a write-off.
Sunday the 13th continues with a 10ft SW swell and onshore winds, and the chart says "poor surf conditions". The energy is high (4281), but the wind is terrible.
The rest of the week from Monday the 14th to the 19th is a mix of big, messy swells and onshore winds. The energy levels are high (878-7437) but the conditions are poor. The standout for the whole period is undeniably the Sunday morning, the 6th of September. That's your call to action.
Rusty out.

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.
