The Lowdown
G’day, it’s Rusty here. Let’s be straight with you—this isn’t a week for the faint of heart. We’re looking at a pretty bleak stretch for Muizenberg over the next two weeks. The issue isn’t always swell, but the wind. It’s just on it or cross-on most days, turning what could be decent waves into a washing machine.
The first few days are a write-off. Thursday and Friday have cross-on breezes, with the swell blowing out. Saturday sees a strong onshore wind with a building swell, and it’s just messy. Sunday morning is still average, but then we get a brief glimpse of something better. Sunday afternoon, the wind drops right out to glassy, and we’ve got a clean 4ft SW swell at 14 seconds. It’s not huge, but it’s the best we’ll see for a while. The wave energy is moderate (696). It will be rideable, but this spot can be inconsistent, and this is one of those days you need to be patient.
After that, we go back into the doldrums. Monday and Tuesday have offshore winds, but the swell drops away. We get a bump on Tuesday afternoon with a 5ft SW groundswell at 18 seconds, but the 35 km/h offshore wind will be making it hard work. It’s more of a promise than a reality.
The following week is where it gets properly grim. From Wednesday the 16th through to the 22nd, the wind is just relentless onshore, and we’ve got periods where the swell is over 7ft. This is a real battle. The weekend of the 20th and 21st sees some serious onshore wind and a short-period SSE swell, which is just ugly. You wouldn’t want to be out there unless you’re a masochist.
We finally get a bit of a reprieve on Tuesday the 23rd when the wind drops, but the swell is tiny and short-period. Then, the real standout of the whole forecast arrives on Thursday the 24th. We’ve got a light offshore breeze, a clean 3ft SW swell with a 15-second period, and it’s looking like the best conditions of the entire run. It’s not big, but the combo of light offshores and a clean groundswell will make it worth the paddle out. Keep an eye on that Thursday afternoon. Just remember, this is a beach break, and long period swells like this can still close out here, so pick your bank carefully.
There’s a lot of poor conditions here, a lot of waiting. But that Thursday the 24th looks like the chance to actually have some fun. Until then, maybe find something else to do.
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.
