The Lowdown
Alright folks, Rusty here. Let's have a proper look at what the next couple weeks are serving up for us at Muizenberg.
Straight up, the first week and a half is a bit of a write-off. We've got a big gap here with no real surf to get excited about until well into the second week. The onshore winds are just relentless. From Saturday the 12th all the way through to late in the week, it's a steady diet of strong SE winds blowing straight onshore, making a mess of things. The water is sitting at 59°, which is just a touch cooler than usual for this time of year. The swell energy is kicking, with values well over a thousand (1092 to 1886), but with that rubbish wind, it's all chop and no shape. Honestly, for most of that first week, you'd be better off taking up kite surfing with that wind, because paddle surfing is going to be a frustrating battle.
Now, we finally get a sniff of something decent towards the end. The morning of Saturday the 19th looks a little better with a light E wind, a 5ft swell from the SW, and the swell energy is still high at 962. It's only cross-on though, so it's a marginal call, but a glimmer of hope.
The real standout, the one to circle on the calendar, is the morning of Sunday the 27th of September. This is the one. We’ve got a 5ft SW groundswell with a very long period of 18 seconds. That long period means the waves will have proper power and shape, and it’s packing some serious energy (1285). The wind is light and offshore from the WNW, which will groom it into clean, lined-up walls. This is your best bet by a country mile. It's a classic Muizenberg corner, and that offshore breeze is the key. Crowds are always a factor here, so get in early.
The afternoon of the 27th is still holding decent 5ft swell with that long 18-second period, but the wind swings onshore from the south, so the magic won't last.
So, to sum it up: suffer through the onshores for the first ten days, then get ready for a magic Sunday morning on the 27th if 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.
