The Lowdown
Alright folks, Rusty here. Let’s have a look at what Muizenberg has got cooking for us over the next couple of weeks. It’s a bit of a slow burn, so don’t expect perfection every day, but there are a couple of windows that’ll get the stoke up.
Right off the bat, the start of the period is a write-off. Sunday the 9th and Monday the 10th are getting hammered by a strong SSE wind and some messy, lumpy swell around 8ft. The water is sitting at about average for this time of year, nothing unusual there, but the conditions are just too ugly to even think about paddling out.
We’ve got a few days of nothing really worth chasing until Wednesday morning the 12th. That’s when things start to turn. A long-period SW groundswell starts showing up, with a period of 18 seconds. The combined energy is moderate (1472) but the real story is Wednesday afternoon. The wind goes glassy, the swell is a clean 4ft, and we get “excellent surf conditions for experienced surfers” flagged. That’s the first real standout. The long period will make for proper, well-shaped lines, though at a beach break it might pitch a bit straight. Keep an eye on the tide.
Thursday the 13th stays clean with cross-offshore winds and a similar 6ft SW swell, but the quality drops to “marginal.” Friday through Sunday are small but clean, with knee-to-waist high waves and light winds. Not terrible for a longboard or a foiler.
Now, here’s the next real highlight. Monday morning the 17th of August is a beauty. We’ve got a 7ft SW swell with a 16-second period and glassy conditions. The combined energy is strong (2228) and it’s labelled as “excellent surf conditions for experienced surfers.” This one is for the crew who know what they’re doing—7ft is solid and it’s going to be pumping. The wind is glass, so it’ll be as clean as it gets.
The following Wednesday the 19th also offers a good look with a 6ft SW swell and a gentle offshore wind out of the NW. It’s consistent and clean, a solid option for intermediate surfers. Keep in mind, this spot can be inconsistent, but when it lines up like this, it’s worth the wait.
The second week is more of a mixed bag. Thursday the 20th gets blown out again by onshore winds, so skip that. Saturday the 22nd of August is a promising long-range call. We’ve got a 6ft SW swell with a 16-second period and a moderate offshore wind. The energy is strong (1837) and it’s another “excellent” rating. That’s a good session in the making, but it’s a week and a half away, so don’t book the day off just yet.
Sunday the 23rd and Monday the 24th look like they’ll get messy again with onshore winds and dropping swell. All in all, the best bets are Wednesday afternoon the 12th and Monday morning the 17th. The 17th is the pick of the litter.
This is Rusty, signing off.

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.
