The Lowdown
Right then, let’s have a look at what’s on offer for Muizenberg. I won’t lie to you, it’s been a tough start to the period and we’re paying for it now. The first few days are a write-off. Friday the 11th and Saturday the 12th are a complete mess with strong onshores in the 22 to 25 mph range and poor surf conditions. We’re talking a complete no-go. The water temp is sitting at 60°F, which is about average for this time of year, so nothing unusual there. The combined swell energy is bouncing around moderate to strong (729 to 2008), but with that wind, it’s all just a washing machine.
Sunday the 13th is only slightly better – still onshore and choppy, with marginal surf at best. That theme carries on through Monday and Tuesday. We’ve got a bit of a drop in swell size, and while Tuesday the 15th sees offshore winds from the NNW with a very long 19-second period SW groundswell, the swell is tiny, only 1ft to 4ft. The combined energy is low to moderate (236 to 665), so it’s clean but just not enough push for a proper session.
Now, if you’ve got patience, there’s a little light at the end of the tunnel. Saturday the 19th morning is the first real bright spot. We get glassy conditions with a whisper of wind from the NNW at just 3 mph. The swell is small, 3ft from the SW with a 12-second period, and the combined energy is weak (281), but it will be clean as a whistle. It’s not going to be big, but for a beginner looking for a gentle roll, this is your moment.
The following week gets more interesting. Monday the 21st morning is another glassy one, with the wind dropping to 3 mph from the SSE. Swell bumps up a touch to 3ft from the SW, 14-second period, and combined energy is moderate (391). Again, clean and small.
But the real standout, the one to circle on your calendar, is Thursday the 24th. We’ve got a gentle offshore wind from the NNW, surf around 4ft from the SW with a solid 13-second period, and combined energy of 556 (moderate). The conditions are described as “expect very good surf conditions”. This is the pick of the bunch. The swell direction (SW) is not the optimum SE the wave likes, but with offshore wind cleaning it up, Muizenberg will have some nice, shapely lines. It’s a beginner-friendly break, so the 4ft is perfect for a longboard. Just keep in mind crowds are listed as “often” here, so expect plenty of company out the back.
Friday the 25th also has gentle offshore winds in the afternoon with clean 3ft surf. A nice follow-up session.
There’s a bit of a run of marginal stuff after that, with some onshore winds returning, but Thursday the 24th is your best bet by a long shot. It’s the only day that really has it all together.

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.
