The Lowdown
Hey folks, Rusty here. Let’s break down what’s coming for Yzerfontein over the next two weeks. It’s a tale of two extremes – slim pickings at the start, and then some serious beast-mode swell.
We start off Wednesday the 19th of August – nothing doing. The swell is 8ft from the SW at 12 seconds, but it’s crossed up with a 12 mph south wind and the wave energy is strong but sloppy at 2073. Not worth the paddle.
Thursday the 20th is the first real call. The morning glass-off at Yzerfontein (beach and reef) shows 10ft of SW groundswell, a solid 13-second period, and light SSE wind making it clean. Wave energy is very strong at 3020. That’s big – over 8ft – so this is for experienced surfers only. The afternoon gets lumpy but that morning is a winner.
Friday the 21st backs off to 7ft SW with an 11-second period. Wave energy is moderate at 1242. Morning is cross-shore and clean enough, but nothing special. The afternoon turns onshore.
Saturday the 22nd – forget it. Only 4ft SSW and messy, wave energy weak at 509. Leave the board at home.
Sunday the 23rd is another standout – the best of the week. Morning has 8ft of WSW groundswell at 13 seconds, with a light SSE offshore breeze. Clean and powerful, wave energy very strong at 2329. Again, expert-only at that size. The afternoon gets cross-shore and fades.
Monday the 24th and Tuesday the 25th sit around 5–7ft. Tuesday morning gives you 7ft of SW swell with a long 14-second period and clean SSE wind. Wave energy is strong at 2050. That’s a fun session for intermediates, but the long period might make the beach breaks a bit straight – stick to the reef sections for better shape.
Wednesday the 26th through Friday the 28th are all average – moderate energy between 900–1700, cross-shore breezes, and nothing to get stoked about. Swell stays around 4–7ft.
Now, from Saturday the 29th of August onward, we get a massive pulse. Saturday morning is 12ft SW at 14 seconds, wave energy a massive 4347. The afternoon jumps to 13ft with a 22 mph SSE cross-off – wave energy hits 6901. Sunday the 30th is 10ft with a 28 mph SE wind, also clean but enormous. This is huge, dangerous surf – only for the experienced crew. Those strong winds and big swell make it a potential kite spot more than a paddle session.
Monday the 31st drops to 5–7ft, with fresh, clean SE wind. Wave energy is moderate at 918–1315. Workable for a session, but not a highlight.
The first days of September see another spike. Wednesday the 2nd has 10ft WSW at 12 seconds, and Thursday the 3rd hits a massive 16ft WSW at 14 seconds, wave energy at 8675. That’s huge – again only for experts. Those long-period groundswells will work best on the reef to avoid closeouts.
So the real standouts are Thursday the 20th and Sunday the 23rd of August – both mornings offer clean, powerful, expert-level surf.
Rusty.

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.
