The Lowdown
Alright folks, Rusty here. Let’s have a look at what the ocean’s got cookin’ for us. It’s a bit of a mixed bag, but there’s a couple of windows that’ll get the blood pumping.
Right now, we’ve got a bit of a wait on our hands. The good stuff is pretty thin on the ground for a stretch, but don't lose hope. The water temp is sitting at a cool 58°F, which is a bit colder than normal for this time of year – you’ll want a good steamer.
The first real glimmer comes on Sunday the 13th. Sunday afternoon at Muizenberg is where it’s at. We’re looking at a clean 4ft swell rolling in from the SW. The wind is dead glassy, which is a massive positive – the face will be like a mirror. That swell is carrying some serious weight with a combined wave energy of 1034, and a long 14-second period, so those sets will have some push. It’s a bit of a standout for the near-term, but it’s only for experienced surfers; it’ll be clean and lined up.
Then things go quiet again. There’s a long dry spell from Monday the 14th all the way through to Friday the 18th, with howling onshores and messy conditions. Nothing worth paddling out for.
Now, if you can wait, keep your eye on Saturday the 19th morning. The swell drops a hair to 4ft from the SW, but the wind goes glassy again. Combined energy is still pumping at 917. It’s another chance for some clean, groomed lines. Sunday the 20th morning is also glassy with 4ft swell, but it’s a little weaker.
Further out, there’s a pulse showing up around the 26th of September that jumps to 8ft from the WSW, but the wind is howling onshore, so it’s a write-off for surfing. Then on the 28th, we’ve got some serious size – 8ft and 10ft from the SW and SSW – but again, those strong onshore winds ruin the party. That’s a lot of juice with energy readings of 3278 and 2952, but without clean wind, it’s just a washing machine. Not for the faint of heart or the average joe.
Honestly, the best of the bunch is that glassy Sunday the 13th afternoon. Grab it while you can.
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.
