The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the menu for the next couple of weeks.
We’ve got a solid run of groundswell coming in from the WSW, and the first surf worth paddling out for kicks off on Wednesday, 12th August. The water temp is sitting at 55°F, which is a good 4°F colder than normal for this time of year – so yeah, it’s nippy. You’ll want a thick steamer and maybe some booties.
The standout start is Yzerfontein, a beach and reef setup. Wednesday morning is looking prime with a clean 6ft swell from the WSW, a long 18-second period, and a moderate offshore breeze from the ENE. The wave energy is pumping (2183), so there’s plenty of push. This is excellent surf for experienced surfers – the power is real, and the sets will have some serious length to them. Those long-period waves will be better on the reef sections, so find your line. It’s a bit exposed, but with that offshore wind, it’ll be clean. Watch out for crowds, though – it can get busy here.
The clean conditions hold for Wednesday afternoon as well, with a gentle offshore wind from the ESE, still packing that 6ft swell. The energy drops slightly (1965), but it’s still a very good session.
Thursday the 13th gets a bit tricky. The swell jumps to 7ft in the morning with a 17-second period, still WSW, but the wind swings to a fresh N cross-off at 22 mph. The energy is massive (3019), but the wind is making it messy. The afternoon is a cross-on mess. Not the one.
Friday the 14th is a write-off for me – cross-shore winds and a bit of chop on a 6ft swell. The energy is still solid (1432), but the quality isn’t there.
The real gem of the whole window might be Sunday morning, 16th August. Glassy conditions with a 6ft WSW swell at 14 seconds. The wave energy is 1267. It’s clean, it’s fat, and the wind is nearly non-existent. That’s a morning of pure, lined-up walls. Go early.
Monday the 17th is another big one. Glassy in the morning again with a 8ft swell from the WSW, 13-second period. That’s big, heavy, and only for the experts (energy 2279). The afternoon gets a bit of cross-on wind, but the morning will be a proper session for the chargers.
After that, the swell starts to drop and quality fades. There’s a bit of a gap from Tuesday 18th afternoon through to the end of the week, with a lot of cross-shore wind and dropping energy. The 20th is basically blown out.
We get a glimmer again on Saturday 22nd – a morning with 5ft from the SW, 14-second period, clean with a gentle cross-off breeze. The energy is 1429, and it’s a much better call than the week before.
The final week from 23rd to 26th is pretty slim. The swell is small, periods are short, and the wind is all over the shop. Not much to write home about.
Then, on Thursday 27th August, we get another glassy start with 4ft from the WSW, 13-second period, and gentle ESE airs. The energy is 558, but the conditions are clean. It’s a nice little finisher for the two-week look.
If you’re picking a single best session, it’s Sunday 16th August – glassy, clean, 6ft, and a long period. That’s the one. Runner-up is the Wednesday 12th morning for the power and the offshore wind.
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.
