The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the Cape Town stretch. Gotta be honest off the bat, the next few days are a bit of a write-off for a proper surf. The whole first week is a bit of a struggle, so we’re looking at a long wait for the good stuff.
The forecast is pretty bleak right through the first week. We’ve got solid swell, but the wind is just a mess. Expect a lot of onshore and cross-onshore slop. The first few days from Tuesday the 18th to Monday the 24th are full of wind-affected, choppy conditions. The combined energy is moderate, around 1525 (moderate wave energy), but the quality is just not there. It’s a real shame. We’ll see a bit of a window on Saturday the 22nd afternoon with a cleaner cross-off breeze and a 7ft SW swell, but it’s still not the standout.
The real payoff comes at the end of the month. The absolute standout is Muizenberg on Friday the 28th of August. The morning session is gonna be the one. We’re looking at a solid 8ft SW groundswell with a very long period of 16 seconds. That’s proper energy pouring in – the combined energy is a massive 3588 (strong to very strong wave energy). The wind is light NW, a gentle offshore breeze, so the waves will be clean and lined up. This is a big one though; at 8ft and with that much energy, it’s strictly for the experienced crew. This is a session you’ll be telling stories about.
After that, the swell drops a bit but there’s another good run. On Sunday the 30th of August, the afternoon session at Muizenberg looks amazing. The swell is still a chunky 7ft from the SW, period is a long 14 seconds, and the wind goes glassy. Absolutely pristine conditions. The combined energy is 1618 (moderate to strong wave energy). The water temp is about average for the time of year, so a 3/2mm wetsuit should be fine.
The following Monday, the 31st of August, keeps the wave train going with a 7ft SW swell and clean offshore NNW winds all day. Also a good call for the experienced surfer.
So, to sum it up: the first week is a washout. Just wait it out. The real surf kicks off on Friday the 28th of August. That’s your best bet for a proper, powerful, clean swell. The Sunday and Monday that follow are also excellent, but that Friday morning is the one.
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.
