The Lowdown
Alright folks, Rusty here. Let's have a look at what Muizenberg has on the cards over the next couple of weeks. Gotta be straight with you, it's a bit of a mixed bag, and we're staring down a lot of noise before we get to the real gems.
Right off the bat, the water at Muizenberg is sitting at 56°, a full 5° colder than what's normal for this time of year. That’s a notable chill, so a good, thick wetsuit is going to be your best mate.
The first week is a write-off for the most part. We’ve got a run of poor conditions stretching from now through the first few days. Winds are onshore or cross-onshore from the SSE and S, directionally wrong for this spot, and they’re messing up what little swell is around. The energy levels are weak to moderate, mostly in the 100 to 800 range, and the wave comments are all “poor surf conditions.” There’s a slight uptick in swell energy on Thursday the 10th with a 6 ft SW swell hitting a combined energy of 1191, but those onshore winds will trash it. Don’t bother.
We finally see a glimmer of hope on the morning of Sunday the 13th. Winds go light and cross-shore from the ENE, and there’s a 4 ft SW groundswell with a 14-second period rolling in. The energy is moderate, around 986. It's labelled “marginal,” but that light wind might carve out a few clean ones if you’re picky. The afternoon gets a bit bigger at 7 ft from the SSE, but the period drops to 10 seconds and the wind turns cross-onshore again.
Now, the standout dawn patrol is on Monday the 14th. We get the first proper window of offshore wind, blowing from the NW at 12 mph. The swell is a bit small, at 3 ft from the SW, with a 12-second period and a combined energy of 287. It’s light and clean – the text says “expect good surf conditions.” It won’t be big, but it’ll be the cleanest we’ve seen in days. Snag a log and make the most of it.
Looking further ahead, the real meat is on Saturday the 19th of September. The morning looks magic: glassy conditions with a whisper-light WSW breeze and a clean 4 ft SW groundswell. The energy is moderate at 433. “Expect good surf conditions” is what the chart says, and for Muizenberg, glassy is about as good as it gets. If you can, that’s your call.
But if you’re an experienced surfer chasing a proper session, circle Wednesday the 23rd of September. We’ve got strong offshore winds from the NNW at 12 mph all day. The morning starts with a solid 10 ft swell from the WSW, though the period is a short 10 seconds, which is a little weak for a wave that size. The energy is very strong at 2844. It’s labelled “excellent surf conditions for experienced surfers.” By the afternoon the swell drops to 8 ft from the SW with a better 11-second period, and the energy is still strong at 1428. These are heavy, powerful waves with offshore wind. Not for the faint-hearted, but for the crew who know what they’re doing, this is the set of the month.
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.
