The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for our local stretch. Honestly, the next week and a half is a write-off—strong winds and messy conditions are going to keep things ugly. We’ve got a solid gap of poor surf stretching from today right through to the 23rd of September, so don't bother paddling out unless you like getting blown off your board.
Muizenberg is the only game in town, but it’s exposed to the south-westerly swell and needs clean conditions to work. Right now, the water is sitting at 58°, which is a bit colder than usual for this time of year. The wind is mostly howling onshore from the SSE, killing any chance of a wave.
There’s a light at the end of the tunnel though. On Thursday the 24th of September, things finally flip. We get a light offshore breeze from the NW, and the swell cleans right up. The morning session will see a 4ft SW groundswell, with a long period of 13 seconds, bringing some proper energy (combined swell energy: 502). That's a solid, lined-up wave. It’s not massive, but it’ll be glassy and fun for a beginner-friendly spot. Crowds are often here, so expect company, but the quality will be worth it. The afternoon stays clean with a 3ft SW swell and a light offshore.
The stand-out session, the one you circle on the calendar, is Friday the 25th of September in the afternoon. The swell bumps up to 5ft from the SW, with a 14-second period, and the wind goes light and variable, cross-offshore. That’s a recipe for some of the best waves we’ll see all forecast period. The water will still be clean, and the energy reading (998) is pushing into strong territory. This is the pick of the bunch.
Beyond that, it gets windy again and turns sloppy. Sunday the 28th shows a big spike in size, with 8ft SSW swell on the Monday morning, but it’s blown out with strong onshore winds—too much for this break and only for experts anyway. Don’t get tempted.
So, keep your powder dry until the 24th, and make sure you’re out there on the afternoon of the 25th.
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.
