The Lowdown
G’day, Rusty here. Let’s talk about what’s brewing for Yzerfontein. It’s a beach and reef setup, open to the swell, and pretty consistent overall. Water temp’s about what you’d expect for this time of year.
The first couple of days are a bit of a bust. Tuesday the 18th and Wednesday the 19th have some solid 8ft to 8ft WSW and SW swell, but the wind is cross-shore and the wave energy is strong (2329 down to 1638). The report says marginal, and with a cross-chop, it’s not going to be fun.
Thursday the 20th morning gets big – 12ft SW swell with a 13-second period, clean cross-off wind, and energy at 3587. That’s a lot of juice, but it’s too big for most folks at this break. Expert only. The afternoon drops to 10ft but the wind turns cross-shore.
Friday the 21st morning is a bit smaller at 7ft SW, light cross wind, energy at 1306. Still marginal, but cleaner. Could be a sneaky one.
Saturday the 22nd is a write-off with cloudy skies and cross-on wind. Sunday the 23rd morning is the real deal – clean cross-off wind, 8ft SW swell at 12 seconds, energy at 1976. The forecast calls it excellent for experienced surfers. That’s the top pick of the first week.
Monday the 24th drops off, but Tuesday the 25th morning is another clean one – 8ft SW swell, 14-second period, cross-off wind, energy at 2419. That’s a long-period groundswell, so it’ll have power, but might be a bit straight for the beach. Still a good one.
The end of the month gets huge. Friday the 28th morning is 13ft SW, 17-second period, energy at 8543. That’s massive and only for the brave. Saturday the 29th and Sunday the 30th have clean 8ft to 10ft SW swell, but the wind is fresh on Saturday. Sunday the 30th afternoon is another big clean one at 10ft – expert only.
Into September, Wednesday the 2nd morning is glassy with a 5ft WSW swell, 11-second period, energy at 799. That’s a small, clean session – perfect for a longboard. The forecast says very good conditions.
So, the standouts? Sunday the 23rd morning for experienced surfers, Tuesday the 25th morning for that long-period groundswell, and Wednesday the 2nd September morning for a glassy, smaller day. The rest is either too big, too choppy, or just marginal.
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.
