The Lowdown
Alright, Rusty here. Let’s talk about what’s on the cards for our local stretch.
Straight up, it’s a bleak run for Muizenberg over the next 16 days. There’s nothing worth paddling out for, so I’d say save your energy. The first real chance of anything surfable doesn’t show up until Tuesday 22nd September, and even then it’s only marginal. We’re looking at a long gap of poor conditions until then.
From Monday 14th, we’ve got some small swell around 2ft from the SW, with clean offshore winds, but the wave comment says poor surf conditions – it just won’t have any shape or push. The combined energy is weak (136), so you’re looking at dribbly, gutless waves. Water temp is 58°, which is a bit colder than usual for this time of year – nothing shocking, but you’ll want a good wetsuit.
Tuesday 15th stays similar – clean but small (2ft to 3ft), and by the afternoon the swell period jumps to 16 seconds, giving it more energy (493), but still poor quality. That long period groundswell on a beach break like Muizenberg often makes things too straight and hard to catch.
Wednesday 16th through Monday 21st is just onshore trash. Swell builds to 6ft to 6ft on Wednesday and Thursday, with SE winds howling on it. The energy ramps up – 1153 on Wednesday morning, 1355 on Wednesday afternoon – but the wind is onshore, so it’s messy and blown out. Too big for beginners and not clean enough for anyone else.
After that, it’s more of the same: onshore winds, lumpy conditions, and poor quality surf. The only real glimmer comes on Tuesday 22nd September morning with a marginal call – a tiny 3ft SSW swell, 13 second period, light breeze, and moderate wave energy (614). It’s not good, but it’s the least bad option. By the afternoon, it’s 7ft of SSE windswell, cross-onshore and choppy – that’s kite-surf territory, not paddle.
Later in the week, Friday 25th September morning has a little window: 3ft SW swell, 11 seconds, light WNW cross-off wind, clean. The combined energy is low (191), and it’s described as “surfable but very ordinary”. Not a standout by any stretch. That’s about as good as it gets.
Beyond that, the last few days of September and into the 28th and 29th are all onshore wind, small swell, and poor conditions. The 29th has marginal light cross-shore winds, but the swell is still tiny – 3ft with 14 seconds period – and the energy is moderate (372). Nothing to get excited about.
So the honest truth: there’s no proper swell window here. The only time the wind cleans up, the swell is tiny, and when the swell has size, the wind ruins it. Best bet? Keep an eye on the forecast for changes, but for now, it’s a long flat spell. Not much more to say.
Rusty.

Information about the Muizenberg Surf forecast
The above surf forecast table for Muizenberg provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Muizenberg can be found by selecting the local surf guide option on the grey menu. Our Muizenberg 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 (Muizenberg) 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 Muizenberg 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.
