The Lowdown
Alright folks, Rusty here with a look at what’s coming our way for the next couple of weeks. We’ve got a bit of a mixed bag, with some clean windows but a heck of a lot of onshore chop to wade through too.
The forecast kicks off at Muizenberg (South Africa) from Monday the 17th. We’re looking at a solid 6ft swell from the WSW with a period of 13 seconds – that’s a nice, solid groundswell with good energy (1042). The water is sitting at 57°, and that’s a good 4° colder than usual for this time of year, so you’ll want a thick steamer. Monday morning is looking pretty workable with a cross-offshore breeze, so the waves should be clean despite the cloud cover.
Monday afternoon actually improves a bit with light rain and the same 6ft swell. The energy picks up slightly (1066), and it's looking excellent for experienced surfers. The cross-off wind is keeping things tidy.
Now, Tuesday the 18th is where things get ugly. The swell sticks around at 6-6ft from the SW, but a strong SSE wind swings onshore, turning the place into a choppy mess. Wednesday and Thursday are more of the same – onshore wind and messy conditions. The swell gets a bit bigger on Thursday morning, hitting 8ft from the SW (energy of 1817), but with moderate cross-onshore winds at 12 mph, it’s just a big, blown-out wall. That's kite-surf territory, not paddle.
Friday the 21st offers a brief tease in the morning with a 5ft SSW swell and an onshore wind, but it’s marginal. The afternoon drops to 4ft and gets worse.
Here’s the real standout: Saturday the 22nd. Morning at Muizenberg is nearly perfect for a session. The swell is a clean 5ft from the SW, period is 11 seconds, and the wind is a dead southerly at only 3 mph – pure glass. The combined energy is moderate at 457, but that glassy surface is the real prize. Get out there early before it gets too crowded, because it’s often busy here.
Sunday the 23rd through Monday the 24th is another rough patch. The wind goes back onshore, the swell drops off to 4ft to 4ft, and it’s mostly a write-off.
We get another good window on Wednesday the 26th of August. The morning offers 4ft of SW swell at 13 seconds with glassy conditions again, light wind from the SSE. That’s a real gem for some clean, fun waves.
Thursday the 27th looks promising too, especially in the afternoon. The swell is 4ft from the SW, but the wind is a cross-offshore from the W at 9 mph, keeping it clean. The energy is light (476), but the shape should be there.
The final week is a tale of two halves. Friday the 28th brings a bigger 6ft SW swell (energy 1400) with a nice long 14-second period, but the wind is onshore again. The weekend of the 29th and 30th is similar – size is there (up to 8ft on the 31st with energy at 2592), but the wind is onshore and strong, making it a messy, expert-only affair if you’re brave.
Best Bet: Without a doubt, Saturday 22nd August morning is your ticket. That glassy surface on a clean 5ft swell is as good as it gets in this stretch. Wednesday 26th August morning is a close second.
Stay frothy.

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.
