The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the menu for Yzerfontein over the next couple of weeks.
We’ve got a mixed bag coming up, with a solid start followed by a bit of a lull, and then some serious power later on. The first few days are looking good for those who know what they’re doing, but there’s a gap in the middle where the surf drops off, so time your session right.
Monday, September 7th is your best early call. The morning is absolutely glassy with a 6ft swell from the SW at a juicy 14-second period. That groundswell is packing a heap of energy (1418) and the wind is dead calm. The waves are going to be clean and powerful, a proper standout for experienced surfers. The afternoon stays clean but the wind shifts to a cross-off S breeze at 9 mph. The water temp is running about average for this time of year, so a spring suit is fine.
Tuesday, September 8th sees the swell drop off fast. The morning is a weak 3ft from the WSW with a light cross-on breeze that’ll mess up the face. The afternoon is even smaller at 3ft. This is the start of a quiet spell.
Wednesday, September 9th is a write-off. The swell is tiny, around 3ft, and a moderate S cross-breeze is chopping it up. The wave energy is weak (360). Not worth paddling out.
Thursday, September 10th is a big one, but you need to be an expert. The morning brings a massive 10ft SW groundswell with a very long 16-second period. The combined energy reading is a huge 3905, and the wind is a clean cross-off from the SSE. This is serious, powerful, and potentially dangerous. It’s too big for most, but if you’ve got the skills and the right board, it’s a raw, grinding session.
Friday, September 11th is still big but messy. The morning has 7ft of WSW swell, but the wind is a fresh 19 mph cross-off, leaving it clean but still heavy. The afternoon drops to 6ft but the wind is similar. A tough one.
Saturday, September 12th is a redemption. The morning is a beauty with a clean 5ft SW swell, light offshore airs, and a moderate energy (1294). The waves will be clean and fun. The afternoon gets a bit lumpy as a 7ft swell bumps up with a light cross-on breeze.
Sunday, September 13th through Monday, September 14th is a messy patch. The swell hangs around 6ft to 7ft, but the wind is fresh and cross-shore, creating chop. Not great.
Tuesday, September 15th is another day for experts only. The morning sees a massive 10ft WSW swell with a very long 16-second period, and the energy is a colossal 5155. The wind is a fresh cross-shore, so it’s lumpy and unpredictable. The afternoon gets even bigger at 13ft but with a cross-on wind, making it a full-on survival mission.
Wednesday, September 16th is a big cleanup. The morning has a 10ft SW swell with a clean cross-off wind from the SSE. It’s still too big for most, but the surface will be a lot smoother. The afternoon is 8ft and clean.
Thursday, September 17th sees the swell drop to a manageable 4ft, but the energy is low (887). Clean conditions again, but small.
Friday, September 18th is a sneaky good one. The morning gives you a solid 7ft S swell, clean, with light winds and excellent conditions for experienced surfers. The energy is moderate (1008) and the waves should have some shape.
From Saturday, September 19th onward, the surf fades again. The weekend has small, weak waves and cross-shore winds. The following week is mostly the same story – moderate swell but with fresh cross-shore winds that keep it lumpy, not glassy.
The standout: Definitely Monday, September 7th morning for the glassy, powerful 6ft SW groundswell. The other standout is Thursday, September 10th morning for the sheer, raw power of a 10ft SW groundswell, but that’s strictly for the experienced crew.
Keep your eyes on the sky, Yzerfontein.
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.
